  • Zambia facing a democratic crossroads as it enters a fresh constitutional crisis

    The election of Zambia’s president, Hakainde Hichilema, in 2021 was widely interpreted as a victory for democracy. Zambia had suffered rising repression under former leader Edgar Lungu, but Hichilema promised democratic accountability. However, there are now concerns that his government is promoting constitutional changes that would entrench ruling-party dominance.

    Hichilema has proposed a bill that would increase the number of MPs by over 60%. It would also introduce elements of proportional representation to create a “mixed” electoral system, and create reserved seats for women, young people and those with disabilities.

    Zambia’s ruling United Party for National Development (UPND) claims the amendments are needed to correct historical exclusion. But many civil society groups believe this is “gender washing” – using inclusive rhetoric to mask an authoritarian agenda.

    This scepticism is rooted in recent political developments and the text itself. The bill has emerged alongside other legislation that would tighten state control over civic and political space, at a time when infringements on fundamental freedoms in Zambia are growing.

    Many of the bill’s provisions are also vague and some undermine democratic checks and balances, while the progressive aspects are ill-conceived. This makes the proposed reforms, in the words of well-known Zambian constitutional expert O’Brien Kaaba: “deeply problematic and counterproductive”.

    I take no pleasure in saying this. The last time I wrote such an article about Zambia, it was to condemn the persecution of Hichilema after he was arrested in 2017 on trumped up treason charges. I was honoured to receive a letter of thanks upon his release.

    Like many Zambians and international observers, I was hopeful for the new administration. Yet, while the government has kept some campaign promises and negotiated a difficult deal on the country’s debt burden, efforts to restore democracy are now going backwards.

    Weakening a fragile system

    As prominent Zambian civil society leaders like Laura Miti and Linda Kasonde have warned, a number of the proposed changes could enable the government to all-but-guarantee itself a majority in the next elections scheduled for 2026.

    First, the bill would add 55 new constituency-based MPs – more than the total number to be elected through proportional representation. There are concerns that most of these new constituencies will be created in UPND strongholds, helping the party retain a majority even if it loses support.

    These fears have been magnified by the government’s failure to release the Boundary Delimitation Report, which sets out the redrawing of electoral boundaries. This has prevented independent scrutiny of the process and its motivations.

    Second, the rule that parliament must be dissolved 90 days before elections is also being revoked on the basis that this unfairly shortens office terms for MPs. Although MPs would not be supposed to conduct parliamentary business after this point, such a change would exacerbate existing problems. These include the use of government resources and vehicles in the ruling party’s campaign.

    And third, the constitutional amendment increases the number of MPs the president can appoint from eight to ten. In a system already adding reserved seats for underrepresented groups, this lacks justification. Taken together, these changes threaten to further empower the government and explain why a collective of civil society groups recently demanded “an immediate halt” to the process.

    At the same time, the government has not taken the opportunity to remove problematic clauses from Zambia’s constitution. These include the right of the president to dissolve the National Assembly if it fails to “reasonably” perform its duties.

    The government has justified the bill by emphasising the historical underrepresentation of women and marginalised groups in Zambian politics. This is a serious problem, but the bill will not fix it.

    The amendments only create 20 seats for women, 12 for young people, and three for those with disabilities. In a 256-seat chamber, this will do little to address the imbalance and falls well short of the Southern African Development Community’s target of 30% female representation.

    Poorly designed quotas can also reinforce marginalisation. Parties may push women toward quota seats, limiting their participation in regular constituency races. The amendment may thus create a new ceiling: if women only run in reserved seats, female representation would almost halve from 15% now to just 8% in the next parliament.

    A similar issue arises with the proportional representation system more broadly. When only a small proportion of seats are allocated this way, it fails to deliver the benefits of fairness that are associated with true proportionality.

    In other words, the constitutional amendment bill gives the appearance of inclusivity while carefully preserving the government’s incumbency advantage.

    A constitutional rush-job

    Perhaps the most striking flaw in the bill has been the process itself. The amendments have seen such scant public consultation that, in June, the Law Association of Zambia called for them to be withdrawn.

    This concern is shared by the constitutional court, which recently found the government had failed to meet constitutional requirements for public participation. The court recommended restarting a more inclusive process.

    Hichilema, perhaps aware of the likely verdict, preempted the ruling by announcing shortly before the court’s decision that he would pause the process to allow for wider consultation. This is a welcome, but insufficient, development. As the Law Association has argued, the amendments are so badly designed that they do not represent a viable foundation for constitutional review.

    Compounding its other flaws, the legislation is poorly written and vague. In many cases, it also fails to explain how new provisions would actually work in practice. The bill therefore needs to be withdrawn, not revised or deferred.

    Zambia needs a new constitution, but it deserves one that is rooted in evidence, consultation and democratic principles. Anything less threatens to undermine the country’s hard-won democratic gains and Hichilema’s own legacy.

  • Russian Imperial Movement: how a far-right group outlawed by the UK is spreading terror across Europe

    Source: ForeignAffairs4

    Source: The Conversation – UK – By Dale Pankhurst, PhD candidate and Tutor in the School of History, Anthropology, Philosophy and Politics, Queen’s University Belfast

    The British government announced in early July that a far-right group called the Russian Imperial Movement (RIM) will be banned under terrorism legislation. This will make it a criminal offence in the UK to be a member of the group or to express support for it.

    The RIM was at the centre of a string of letter bomb attacks targeting high-profile people and institutions in Spain in 2022. These included a bomb addressed to the official residence of Spanish prime minister Pedro Sánchez, which was intercepted by his security detail.

    Six more letter bombs were mailed to targets including the American and Ukrainian embassies in Madrid, military installations, and weapons manufacturing companies that supply arms to Ukraine. No one was killed in the attacks, which US officials considered to be acts of terrorism.

    Investigators soon announced that they suspected the RIM of being involved. US and European officials alleged that the group was directed to carry out the attacks by Russian intelligence officers.

    What is the RIM?

    The RIM is an ultra-nationalist, neo-nazi and white supremacist organisation based in Russia. It was created in 2002 by Stanislav Anatolyevich Vorobyev, a Russian national who is designated a terrorist by the US government.

    The group seeks to create a new Russian empire, and uses the Russian imperial flag as its sign. The previous Russian empire (1721-1917) encompassed all of modern-day Russia, Belarus, Ukraine, Poland, Finland, Georgia, Armenia and the Baltic states, as well as parts of China.

    The movement does not recognise Ukrainian sovereignty. It sees Ukraine as part of what it calls a global Zionist conspiracy designed to undermine Russia and promote Jewish interests. The RIM has engaged in Holocaust denial and is formally outlawed in the US, Canada and now the UK.

    It also has a paramilitary wing called the Imperial Legions, which operates at least two training facilities in the Russian city of St. Petersburg. The US State Department believes these facilities are being used to train RIM members in woodland and urban assault, tactical weapons and hand-to-hand combat.

    Denis Valliullovich Gariyev, the Imperial Legions’ leader, has in the past called on “young orthodox men” to join the Legions and defend Novorossiya – a term used to describe Russia’s claim over Ukraine. As of 2020, the Imperial Legions was estimated to have several thousand members.

    The RIM and its paramilitary wing have engaged in a wide range of activities and operations. These range from passive alliances with other far-right groups in Europe to providing paramilitary training for terrorist organisations. They have also participated directly in bomb attacks.

    Since 2014, when the conflict in eastern Ukraine began, the movement has trained and sent members as mercenaries to bolster the pro-Russian separatist groups fighting there. Its members have also actively supported the Russian armed forces in Ukraine after the full-scale invasion in 2022.

    After the invasion, posts related to the RIM on various social media platforms such as Vkontakte and Telegram revealed a ramping up of recruitment to join operations in Ukraine. Its fighters have posted videos of themselves in Ukraine armed with weaponry from sniper rifles to anti-tank missiles.

    According to analysts, the movement also maintains strong ties with the Russian private military company, the Wagner Group. Imperial Legions fighters are believed to have operated alongside Wagner mercenaries in Syria, Libya and possibly the Central African Republic.

    Outside of these activities, the movement has been active in supporting far-right organisations in Europe. These include the Nordic Resistance Movement in Sweden and similar groups in Germany, Spain and elsewhere.

    It provides training to these groups through its so-called “Partizan” (Russian for guerrilla) programme. The training includes bombmaking, marksmanship, medical and survival skills, military topography and other tactics. According to the UK government, the Partizan programme aims to increase the capacity of attendees to conduct terrorist attacks.

    Two Swedish nationals who took part in the programme later committed a series of bombings against refugee centres in Gothenburg, a city on Sweden’s west coast, in late 2016 and early 2017. The men were convicted in Sweden, with the prosecutor crediting RIM for their terrorist radicalisation and training.

    The RIM has also provided specific paramilitary training to far-right groups in Finland. Some members of these groups have fought on Russia’s side in Ukraine, while others have attempted to establish a Finnish cell of the international neo-nazi Atomwaffen Division. Police raids in 2023 also unveiled plans to assassinate the then Finnish prime minister, Sanna Marin.

    Links with the Russian state

    The movement has previously been critical of the Russian government. It initially believed the approach of Russia’s leader, Vladimir Putin, to Ukraine was too soft, while the group’s promotion of white supremacy and neo-nazism is at odds with Putin’s pragmatic nationalism within Russia.

    In 2012, the RIM even took part in discussions with other far-right groups in Russia to form an opposition movement called New Force to challenge Putin’s rule. However, the crisis in Ukraine that erupted in 2014 after pro-Russian president Viktor Yanukovych was ousted from power has caused the Kremlin and RIM’s political objectives to converge.

    Indeed, the group can now be viewed as one of the core Russian proxy paramilitaries operating in Ukraine at a time when Putin needs more recruits to continue the war. Western intelligence agencies now believe it has a relationship with officials from Russian state intelligence.

    It is difficult to pinpoint the total number of RIM fighters operating in Ukraine as the involvement of mercenary groups there is a closely guarded secret. However, based on previous intelligence reports on the group’s activities, it is reasonable to assume the number is in the hundreds to low thousands.

    The decision by the British government to proscribe the RIM indicates concern that the far-right group is increasing its operational capacity both in Ukraine and throughout Europe. With its extensive network, the movement will become an increasing threat to security if it is allowed to continue acting as a proxy for Putin’s foreign policy objectives.

  • Katy Perry and her fellow space tourists weren’t exceptions – humanity has long cared about interplanetary style

    When pop star Katy Perry and five other women made a much-publicised trip to the edge of space earlier this year, they faced sharp criticism across both social and traditional media, with sceptics questioning multiple aspects of the mission.

    Much of the backlash centred on the emphasis the crew – which included broadcaster Gayle King and Jeff Bezos’s now-wife, journalist Lauren Sánchez – placed on glamour. Detractors saw their uniforms as at odds with the traditional image of astronauts as explorers, scientific pioneers and envoys of humankind venturing into space.

    The flight suits were designed by New York fashion house Monse Maison’s co-founders, Fernando Garcia and Laura Kim. They also created Sánchez’s 2024 Met Gala look.

    The celebrity crew were first revealed in a photo shared by Blue Origin on April 12, two days before the launch. The unveiling was followed by a series of pre-flight interviews that touched on topics such as makeup, lash extensions and hair styling.

    In one such segment, Perry quipped that the crew “put ass in astronaut”. It’s the type of comment that, while playful, reinforced the criticism that the flight prioritised spectacle over substance.

    Having previously conducted research on governance of space suit design and astronaut safety, I think much of the backlash targeting the crew’s emphasis on glamour is misplaced. Fashion and style has long played a role in space exploration, a defining feature of both science fiction and real-world missions.

    The all-women crew of Blue Origin, in their own way, carried forward this tradition, reinforcing the enduring connection between style symbolism, and space travel.

    Space-faring nations spend millions getting both public and private companies to design suits for intravehicular activity (IVA suits) and extravehicular activities (EVA suits). The priority is not just functionality and safety, but also creating impressive designs.

    High fashion house Prada is currently collaborating with Axiom Inc. to design suits for the forthcoming Artemis Mission, a lunar exploration mission led by Nasa. Another Nasa next-generation spacesuit features an exterior cover designed by Esther M. Marquis, who was enlisted for the project after showcasing her visionary spacesuit designs in For All Mankind, an Apple TV Sci-Fi series.

    The European Space Agency (ESA), meanwhile, has contracted Maison Pierre Cardin to design the uniforms for training in its new lunar mission simulation facility, Luna, in Germany.

    These and many other similar collaborations represent a continuation of the longstanding interplay between art, fashion and space technology. Science fiction books and movies have both influenced and been influenced by advancements developed for space travel.

    Modern space fashion

    Photos and videos from inside the International Space Station (ISS) reveal that their intravehicular activity (IVA) suits are designed for functionality and comfort rather than style.

    It’s a sensible approach, as most crew stay there for extended periods to conduct scientific experiments. In contrast, two of the billionaires most associated with space tourism – Jeff Bezos and Richard Branson – take a different approach. In competing to promote their emerging space tourism ventures, their own trips to space have been carefully curated – with fashion playing a key role.

    From launch to landing, Bezos’ own suborbital space travel with Blue Origin in 2021 lasted 11 minutes, while Branson’s travel in Virgin Galactic’s VSS Unity lasted approximately 90 minutes, with four minutes of experience of weightlessness. However, they ensured that their “look” as they walked to their spacecraft would remain entrenched in our memories.

    Jimmy Fallon jokes about Bezos’s cowboy hat.

    Branson entrusted sports brand Under Armour to make a statement with a dark blue jumpsuit. Nine days later, Bezos appeared on the flight platform sporting a cowboy hat with his light blue flight suit.

    Branson’s crew won more fashion points with their sleek and streamlined suits – and he flew before Bezos – beating Blue Origin’s flight by nine days. Yet Bezos and his crew travelled to a higher altitude.

    As of the date of this article, Blue Origin has flown 58 people into space, whereas Virgin Galactic have flown 61 passengers, including crew. Space suits are an integral part of the experience. No less than a picture-perfect design will be expected for the high price tag.

    Elon Musk’s SpaceX, is the foremost private space enterprise of our time and arguably the one with the most political influence – although the effects of the recent fallout between SpaceX founder Elon Musk and the US president, Donald Trump, on the company remain uncertain.

    SpaceX has also stepped up its design efforts before the first-ever commercial astronaut spacewalk during the Polaris Dawn spaceflight, it unveiled its new EVA suit, dubbed the “space tuxedo”.

    SpaceX’s ‘space tuxedo’ suit reveal.

    During spacewalks, EVA suits are essential for keeping humans alive, making them a vital piece of wearable technology. The space tux was designed by Hollywood costume designer, Jose Fernandez, who also designed the suits for Iron Man and Captain America (an interesting twist given the film version of Iron Man’s alter ego, Tony Stark was reportedly partly inspired by Musk).

    Musk reportedly demanded both IVA and EVA suits to look “badass” while remaining practical. The mission was a success, as the four-member civilian team, led by billionaire Jared Isaacman, travelled further into space than any humans since the Apollo Missions to the moon.

    As we continue to explore the cosmos, fashion will continue to play a role in how we present ourselves to the universe. Whether for scientific missions or private ventures, how we dress for space will reflect our identity and aspirations as a species. This phenomenon did not begin with these glamorous star-studded women embarking on space ventures in their signature bold styles, nor will it end with the scrutiny and negative publicity they have faced.

  • How does the PKK’s disarmament affect Turkey, Syria and Iraq?

    The historic disarmament ceremony on July 11 where members of the Kurdistan Workers’ Party (PKK) laid down their arms marked a pivotal moment in a decades-long conflict in Turkey. The ceremony was described by many who attended as a profoundly symbolic and emotional day that may signal the beginning of a new era.

    During the disarmament ceremony in Sulaymaniyah in the Kurdistan Region of Iraq, 26 PKK guerrillas alongside four senior commanders and leaders of the movement, symbolically laid aid down their arms and burned them. The audience included officials from the Kurdistan Regional Government (KRG), plus politicians, journalists and international observers.

    For more than four decades the PKK has been embroiled in an armed conflict with Turkey that has claimed more than 40,000 lives and shaped Kurdish identity and politics across the region.

    The PKK disarmament ceremony also could mark a new era for the Kurds, one of the largest stateless groups in the world with over 30 million people living across Turkey, Iraq, Iran and Syria. The PKK has said it will now shift from armed resistance to political dialogue and regional cooperation.

    Strikingly, the day after the ceremony, Turkish president Recep Tayyip Erdoğan acknowledged the state’s historical failures in addressing the Kurdish issue. He listed past abuses of Kurds – state-sponsored abductions and extrajudicial violence, the burning of villages and the forced displacement of families – as examples of policies that had fuelled, rather than quelled, the conflict.

    “We all paid the price for these mistakes” he said. He later added: “As of yesterday, Turkey began to close a long, painful and tear-filled chapter.” Erdoğan also announced the formation of a parliamentary commission to oversee the legal steps of the peace process, suggesting a much-needed institutionalised and transparent approach than in previous attempts.

    This hints that the road ahead might include a period of transitional justice. This could compose of different tools used by societies to address past violence and human rights abuses during a shift from conflict to peace and democracy. These may include legal actions such as trials, as well as other efforts to heal and rebuild trust in society.

    Erdoğan also underlined the regional dimension of the agreement: “The issue is not only that of our Kurdish citizens, but also of our Kurdish brothers and sisters in Iraq and Syria. We are discussing this process with them, and they are very pleased as well.”

    PKK fighters take part in a symbolic peace ceremony.

    International dimensions

    While the PKK may be laying down arms, the Kurdish political movement should not be expected to disappear. On the contrary, it is likely to become more active in the democratic sphere — both in Turkey and in other parts of the Middle East where Kurdish people live. It is no secret that the current peace process is the result of shifting geopolitical realities.

    Growing tensions between the US and Iran, Israel’s ongoing war in Gaza, the ousting of the Assad regime in Syria, and shifting power dynamics across the region have all contributed to a geopolitical landscape in which prolonged armed conflict has become increasingly unsustainable — for both Turkey and the PKK. In this context, the current peace process is not merely a domestic initiative.

    It represents a strategic recalibration in a rapidly changing Middle East. For Turkey, stabilising its southeastern border and reducing internal security pressures is essential amid regional volatility.

    Turkey has long maintained strong ties with the Kurdistan Regional Government (KRG) (the official ruling body of the Kurdistan region) in Iraq. However, the situation for Kurds in Syria remains more complex, as Turkey continues to view the Autonomous Administration of North and East Syria (a region that has in effect been self governing since 2012 and where many Kurds live) as a security threat along its border.

    Meanwhile, negotiations continue between the new Syrian government under current president, Ahmed Hussein al-Shara, and the Syrian Democratic Forces (SDF), the Kurdish-led coalition in Syria, which has been historically backed by the US. The SDF seeks to maintain its military autonomy and have its own independent political system — both of which are opposed by Damascus.

    Western nations, particularly the US, remain influential in these talks. The US ambassador to Turkey and special envoy for Syria, Thomas Barrack, is reportedly uneasy with the lack of progress in the talks between al-Shara, and the SDF. He said: “The SDF, who has been a valued partner for America in the fight against ISIS, well-respected, bright, articulate, has to come to the conclusion that there’s one country, there’s one nation, there’s one people, and there’s one army.”

    Another factor here is that a strong Arab-Turkish-Kurdish alliance is unlikely to align with Israeli strategic interests, which may favour a more fragmented Kurdish presence in the region.

    For now, Turkey faces the complex task of overseeing a comprehensive disarmament, demobilisation and reintegration process. This requires not only the decommissioning of weapons and the disbanding of armed units, but also the social and political reintegration of former combatants. The success of this will depend on legal reforms, institutional trust and a genuine commitment to democratic inclusion.

    Erdoğan has been critised for his government’s ongoing non-democratic practices such the appointment of state trustees who replace elected officials and the imprisonment of elected officials.

    And, despite the symbolic disarmament, the Turkish government persists in using the words “struggle against terrorism” — an approach that risks undermining the peace process by criminalising political dialogue and delegitimising Kurdish demands.

    Turkey’s foreign minister Hakan Fidan reiterated that the PKK’s broader network, including the Kurdistan Communities Union (KCK), a group representing Kurds across Iraq, Syria and Turkey, must cease to pose a threat. “We will remain vigilant until every component of the KCK is no longer a danger to our nation and region,” he stated.

    For the PKK, the changing alliances and uncertainties in Syria and Iraq may have made armed struggle a less viable path forward. Yet the sustainability of peace will depend on more than disarmament. It will require ending the criminalisation of Kurds in political institutions and within civil society.

    What comes next will determine whether this moment becomes a historic turning point or another missed opportunity.

  • We can learn a lot from Troy’s trash

    Source: ForeignAffairs4

    Source: The Conversation – UK – By Stephan Blum, Research associate, Institute for Prehistory and Early History and Medieval Archaeology, University of Tübingen

    Beneath the epic tales of heroes and gods, Troy’s true story is written in something far less glamorous – its rubbish.

    When we think of Troy, we imagine epic battles, valiant deeds, cunning tricks and the wrath of gods. Thanks to Homer’s Iliad, the city is remembered as a stage for romance and heroism.

    But long before Paris stole Helen and Achilles raged on the battlefield, the people of bronze age Troy lived ordinary lives – with extraordinary consequences. They built, cooked, stored, traded and, crucially, threw things away. And they did it right where they lived.

    Today, waste is whisked away quickly – out of sight, out of mind. But in bronze age Troy (3000–1000BC), trash stayed close, often accumulating in domestic dumping grounds for generations.

    Having spent more than 16 summers excavating and analysing the bronze age layers of Troy, I’ve learned to read the city’s history this waste.

    Hundreds of thousands of animal bones from cattle, sheep, fish – even turtles – were found alongside vast quantities of pottery shards, ash, food scraps, and human waste. Sometimes, these layers were reused to level floors or build walls, showing how closely intertwined daily life and refuse management were.

    Archaeology’s dirty secret

    This wasn’t laziness or neglect, it was pure pragmatism. In a world without rubbish trucks or sanitation systems, managing refuse was neither chaotic nor careless, but a collective, spatially negotiated – and surprisingly strategic – effort.

    The excavations I have worked on as part of the University of Tübingen’s Troy Project, which has been going on since 1988, have revealed just how deliberate these routines were. Where people chose to dump, or not to dump, speaks volumes about status, social roles, and community boundaries. Waste is the diary no one meant to write, yet it records the intimate rhythms of daily life with unfiltered clarity.

    Far from a nuisance, Troy’s waste is an archaeologist’s treasure trove.

    Over nearly 2,000 years, Troy ended up with 15 meters of built-up debris. Archaeologists can see nine major building phases in it, each made up of hundreds of thin layers, which formed as people lived their everyday lives. These layers act like snapshots, quietly recording how the city changed over time. Some capture hearth cleanings, others record the rebuilding of entire city quarters.

    By analysing the layers and their ratios of bones to pottery, ash concentration, presence of storage jars, grinding stones, or production debris, specific spaces of activity become visible: kitchens, workshops, storage areas, rubbish pits. What appears chaotic turns out to be a carefully structured map of everyday routines – showing where meals were prepared, tools made, and discarded objects left behind.

    The story these remains tell is one of profound transformation. Troy began as a modest agrarian settlement, shaped by the steady rhythms of farming, herding, and small-scale craft. Over time, it grew into a thriving regional centre.

    The archaeological record, rich in refuse, traces this long arc of change. Exotic imports fashioned from stones such as carnelian and lapis lazuli begin to appear, revealing distant trade connections. Specialised metalworking tools emerge alongside monumental architecture. some buildings stretched nearly 30 metres, signalling growing ambitions and expanding capabilities.

    This rise unfolded gradually, reflected not just in grander buildings, but in shifting tools, trade, and how people dealt with what they left behind. Waste management became more organised, with designated areas for different types of waste. This reflects broader shifts in how the community structured space and managed its economy.

    Yet this ascent was interrupted. By the mid-third millennium BC, signs that things were becoming smaller appear. Architecture simplifies, household inventories shrink, production debris declines suggesting economic slowdown or political instability.

    Still, Troy endured. By the mid-second millennium BC, the city revived. Refined ceramics, luxury imports and evidence of social complexity marked a new chapter of recovery and reinvention. This splendid settlement later became the stage for Homer’s Trojan War where Greek warriors faced the daunting task of climbing towering mounds of debris built up over centuries just to reach the palaces.

    A heap worth climbing

    These insights allow us to see Troy not just as a city of walls and towers, but as a living organism shaped by daily routines, unspoken norms and social negotiation. The waste left behind is a remarkably honest archive of bronze age society – beneath myths, stones, and poetry.

    Troy’s trash heaps are the bronze age’s search history. To know what mattered 4,500 years ago, don’t ask poets – ask the garbage. From broken tools to shared meals, from imported luxuries to scraps, this waste reveals the pulse of everyday life and society’s evolving structure.

    Ironically, these mundane refuse layers preserved the bronze age world for us. Without them, we’d know far less about early Troy’s people. Their depth and composition trace changes in economy, technology, and social structure. From scraps to towers of pottery shards, waste archaeology is key to understanding early urban complexity.

    So next time you picture Achilles storming Troy’s gates, remember: the heroes might have been divine, but their city smelled very human.

    Scrolling through social media, it’s hard to miss influencers raiding the pantry for “natural” beauty fixes: baking-soda scrubs, garlic spot sticks, cayenne masks that promise to tighten pores and banish dullness.

    The appeal is obvious. Why pay for a dermatologist-tested cream when everyday ingredients come with antimicrobial or exfoliating properties? Yet what looks sensible in a 30-second reel can translate into painful, sometimes dangerous, DIY disasters.

    Just because it’s edible doesn’t mean it’s safe to put on your skin.

    Garlic, chilli, turmeric and their spice-rack neighbours may contain potent bioactive compounds, but in raw form they are unrefined, unstable and frequently far too harsh for the delicate acid mantle that shields human skin.

    Professional cosmetic chemists isolate biologically active plant compounds, purify them and blend them at precisely calibrated doses suited to the skin’s natural pH. A spoonful of cayenne or a pinch of bicarbonate of soda offers none of that control. Slapping pantry powders on your face risks chemical burns, rashes or long-term damage.

    Concentration is the first stumbling block. A teaspoon of baking soda, for instance, has nothing in common with a safety-tested cleanser that might contain less than 1% sodium bicarbonate balanced by humectants (moisture-attracting ingerdients) and acids.

    Likewise, a swipe of raw cayenne delivers an unpredictable hit of capsaicin, the fiery molecule that dermatologists use in nerve-pain creams, but only at strictly managed strengths.

    Pure kitchen spices also arrive with their own microorganisms: they are agricultural products processed in bulk. Once mixed with water or oil to create a mask they can become bacterial broths, inviting infection rather than a healthy glow.

    Baking soda: more alkaline than your skin can handle

    Baking soda illustrates how quickly a “harmless” staple can upset skin chemistry. Celebrated online for mild antibacterial and antifungal properties, sodium bicarbonate is, in fact, highly alkaline.

    Normal skin sits in the acidic range of 4.5 to 5.5. Apply a thick alkaline paste and the pH shoots upward, disrupting friendly microbes and triggering irritation and breakouts.

    Studies in humans show a bicarbonate paste does not relieve psoriasis itch or redness. On babies, baking-soda soaks for nappy rash have caused hypokalaemic metabolic alkalosis (low potassium levels in the blood), leading to seizures and coma.

    Some influencers say that the same paste that soothes burns is safe, but it can be dangerous. There are reports of baking soda causing severe skin damage – such as deep burns and even tissue death – when it was applied to broken or injured skin.

    Even more alarming are posts touting it as a DIY cancer therapy, on the theory that it “neutralises” tumour acidity. High oral doses have disrupted heart rhythm and caused death.

    Garlic: ancient remedy, modern irritant

    Garlic’s folklore as a “natural antibiotic” fares no better. Raw cloves are loaded with sulphur compounds that behave like caustic chemicals. Direct application has produced allergic or irritant dermatitis and even third-degree burns on lips and eyelids.

    Any scars may outlast the pimple they were supposed to heal.

    Research on allicin, a natural compound in garlic, shows promise as an antimicrobial and heart-protective agent – potentially helping to lower blood pressure, reduce inflammation and prevent heart disease. But that study used purified extracts in lab conditions – not a clove rubbed straight onto skin.

    Chilli peppers: capsaicin isn’t a beauty hack

    Chillies present an even hotter hazard. Capsaicin is licensed for nerve-pain creams yet even pharmacists warn of burning, redness and swelling. Home kitchens, obviously, lack a pharmacist.

    Cooks who handle chillies daily can develop Hunan hand, an intensely painful, burning dermatitis. Despite this, some beauty hacks still recommend cayenne masks for radiance. Airborne or topical capsaicin stings the eyes, triggering involuntary spasms and long exposure can cause lasting corneal injury.

    Inhaling the dust provokes coughing fits and, over time, lung inflammation. Because capsaicin penetrates the skin, repeated use can damage peripheral nerve fibres – dulling your ability to feel heat or pain – and disrupt normal blood flow, which may lead to tissue irritation, delayed healing or increased sensitivity. It can also affect blood pressure, especially in people with underlying health issues.

    A notorious example underscored the danger: a woman suffered agonising vaginal burns after unknowingly using a tampon contaminated with pepper spray that had leaked in her handbag. Even mustard powder can deliver second-degree burns when misapplied.

    Spice rack roulette: staining, burning, dermatitis

    Spices thought to be milder are hardly innocent. Cinnamon is a trendy lip-plumper, yet dermatologists document contact dermatitis and chemical burns. Ginger “glow” masks leave many users with red, irritated skin.

    Clove oil, hyped as a spot cure, has produced caustic injuries. Saffron can cause allergic rashes, while turmeric’s curcumin, celebrated online for anti-inflammatory benefits, often delivers dermatitis and bright yellow staining that lingers for days.

    Dermatologists recommend patch-testing any new skincare product, even “pure” essential oils, on the inner arm for 48 hours.

    Powdered spices also wander: a cinnamon scrub can fill the air with irritant dust that settles in eyes or airways, leaving you sneezing and sore instead of glowing.

    Respect your barrier

    Dermatologists emphasise the importance of protecting the skin barrier: gentle, pH-balanced cleansers and moisturisers help maintain the acid mantle that defends against germs. Your doctor or pharmacist can guide you toward proven plant-based ingredients like niacinamide, aloe vera, or colloidal oatmeal, all of which offer skin benefits without the sting.

    Next time an influencer urges you to “ditch chemicals” or promote “clean beauty” and scoop your skincare out of a spice jar, remember, everything is a chemical. Some belong on your dinner plate – very few belong on your face.

  • Donor-egg pregnancies may come with higher rates of serious complications – here’s what you need to know

    More women than ever are carrying babies conceived with someone else’s egg – but few are told that this might carry greater health risks.

    Pregnancies involving an embryo that doesn’t share the pregnant woman’s DNA are becoming more common. For many, it’s a path to parenthood that would otherwise be closed.

    But emerging evidence suggests that these pregnancies may come with higher rates of complications, including pre-eclampsia, gestational diabetes and preterm birth, and that women are often not given the full picture before treatment.

    As the fertility industry expands and diversifies, it’s time to ask whether patients are being adequately informed about the risks of carrying another woman’s egg – and whether more caution is needed in how these options are presented.

    There are three situations in which a woman may carry another woman’s egg in her uterus.

    The most common is when a woman cannot produce her own eggs but has a functioning uterus. In this case, donor eggs and in-vitro fertilisation (IVF) offer the only route to pregnancy.

    The other two situations involve fertile women carrying a donated egg on behalf of someone else. This happens in cases of gestational surrogacy, where a surrogate carries a baby genetically unrelated to her, or in reciprocal IVF, also known as ROPA or co-IVF. In the latter, one woman in a same-sex couple (or a trans man) donates her egg to her partner, so that both have a biological connection to the child.

    In IVF, fertilisation occurs outside the body and the resulting embryo is transferred into the uterus. But what happens when the egg in the uterus has no genetic similarity to the woman carrying it? Could this cause complications for her or the baby?

    To answer that question, we need to compare outcomes in these situations to pregnancies where the egg shares approximately 50% of the mother’s DNA, either through natural conception or own-egg IVF. Early evidence suggests that having someone else’s egg in the uterus is associated with a higher risk of obstetric complications, including pre-eclampsia, gestational diabetes and preterm birth.

    There are three key comparisons to make. First, donor-egg IVF v own-egg IVF. For infertile women using donor eggs, the most relevant comparison is IVF with their own eggs.

    Second, gestational v traditional surrogacy. In gestational surrogacy, the surrogate carries a donor egg, while in traditional surrogacy, she uses her own. Outcomes can also be compared with the surrogate’s previous natural pregnancies.

    Third, reciprocal IVF v own-egg IVF. In same-sex couples, reciprocal IVF can be compared to own-egg IVF to assess risks.

    A review of 11 studies comparing donor-egg IVF to own-egg IVF found that donor-egg pregnancies had significantly higher rates of hypertensive disorders in the mother, as well as preterm birth and babies that were small for their gestational age.

    A separate review focusing on pre-eclampsia in singleton IVF pregnancies found the condition occurred in 11.2% of donor-egg pregnancies, compared to 3.9% of own-egg pregnancies.

    For women who can only become pregnant using a donor egg, these risks may be worth accepting. But it’s important that women are made aware of the potential complications, especially if carrying twins, which further increases risks.

    Gestational surrogacy

    With colleagues, I conducted a review of eight studies. The research suggests that gestational surrogacy (donor egg) is linked to higher rates of hypertensive disorders and gestational diabetes compared to traditional surrogacy (surrogate’s own egg) or previous natural pregnancies.

    So why is gestational surrogacy often favoured by clinicians and intended parents alike? For some doctors, it can offer greater medical and ethical clarity; for some parents, it can reduce legal and emotional complications. A common assumption is that genetically related surrogates may be more likely to want to keep the baby – but research shows this is not the case. Surrogates rarely seek to retain custody, regardless of genetic connection.

    Evidence on reciprocal IVF is even more limited. A 2022 study of 21 women who underwent reciprocal IVF found that hypertensive disorders occurred in 23.8%, compared to 12.9% of the 62 heterosexual women using their own egg, and gestational diabetes occurred in 9.5% v 1.6%.

    The only study directly comparing reciprocal IVF to own-egg IVF in same-sex female couples is an unpublished conference abstract, which found a higher miscarriage rate (19% v 14%), but reported no maternal or infant outcomes.

    Despite limited data, fertility companies often market gestational surrogacy and reciprocal IVF as reasonably safe options. However, much of the research comes from clinicians affiliated with fertility clinics.

    Crucially, there is still no strong evidence showing that fertile women carrying another woman’s egg have better outcomes than infertile women undergoing the same. But a lack of evidence is not the same as evidence of safety.

    In some cases, pregnancy using one’s own egg may still be possible. For example, fertile women in same-sex couples may only need sperm donation to conceive naturally, rather than going through IVF.

    Women deserve full, unbiased information about the risks. That includes knowing that carrying someone else’s egg may increase the likelihood of pregnancy complications. They can then make informed decisions about whether the potential benefits outweigh the risks.

  • Trump’s Brazil tariffs point more to his enduring bond with far-right Bolsonaro than economic concerns

    After much back-and-forth over several months, President Donald Trump announced on July 9, 2025, that he planned to levy a 50% tariff on Brazilian exports to the United States. While Brazilian authorities, along with leaders of most other countries, have been expecting new tariffs given their centrality to Trump’s economic agenda, the announcement seemingly caught Brazilian officials off guard, as trade negotiations between the two nations were still ongoing.

    Brazil President Lula da Silva was quick in reacting, stating his country could respond in kind, if tariffs indeed come into effect on Aug. 1.

    There has been much speculation about the reasons behind Trump’s decision and timing, with some onlookers noting the proximity to the recent meeting of the BRICS nations, a grouping of emerging economies, including Brazil, which had already drawn Trump’s ire. Others argued that this was a protective measure to defend key U.S. industries, such as steel, which have been facing continued difficulties against cheaper products from Brazil.

    The clearest answer, however, came from Trump himself.

    In a letter to Lula, the U.S. president indicated that his main grievance with Brazil is in fact the trial that former Brazilian President Jair Bolsonaro faces in front of that country’s highest court. The former far-right firebrand is charged for refusing to recognize the result of the last presidential election in October 2022 and for allegedly having led an attempted coup against the democratic institutions and rule of law in January 2023. If convicted, Bolsonaro and some of his closest associates could face long prison sentences.

    A history of meddling

    The only economic rationale mentioned in Trump’s letter, that of a deficit that his country is said to face with Brazil, is belied by the numbers. The U.S. has sustained consistent surpluses in trade with the South American nation for close to two decades now.

    And Steve Bannon, Trump’s former adviser, active cheerleader and primary conduit between the Trump camp and Bolsonaro, was even more blunt than the U.S. president. In an interview with one of Brazil’s main news site, he stated: “Stop the trial and we will reverse the tariffs.”

    As the history of U.S.-Latin American relations ably demonstrates, this is far from the first time Washington has meddled in the region in order to satisfy its own political proclivities. Indeed, particularly during the Cold War, a slew of U.S. decision-makers actively intervened to support friendly right-wing regimes or to otherwise remove from power administrations considered unacceptably independent.

    This was nonetheless the first time in recent history that the official U.S. position is that a foreign nation should face harsh economic punishment unless its current government illegally circumvent the judicary’s constitutional role to stop a major investigation against someone accused of high crimes.

    Trump-Bolsonaro: Mutual admiration

    Of course, Trump’s overt support for Bolsonaro is not surprising, nor new. Their relationship of mutual admiration and ideological affinity hearkens back to the latter’s first presidential campaign in 2018, when he was labeled, to great reciprocal delight, the “Trump of the Tropics.”

    During the subsequent two years when their terms coincided (2019-2000), both men pledged to have a mutual special relationship, though to little consequence – no consequential bilateral projects were put in place.

    Both leaders also share the experience of having failed to obtain a second consecutive term and having supported the derailment of the peaceful transfer of power.

    Now that Trump is back in power, Bolsonaro hopes that the U.S. president will come to his rescue.

    Seeking to obtain explicit support, Bolsonaro’s third son, Eduardo, a member of Brazil’s lower house of congress and his family’s most eloquent international voice, took a leave from his legislative duties and moved to the U.S. early this year. He did so to lobby on behalf of his father based on the fallacious argument that Lula is a left-wing dictator, that Bolsonaro faces a politically motivated trial, and that the U.S. government should act against Lula’s administration.

    Given Trump’s tariff notice and the explicit reasons he gave for it, it seems safe to assume that Eduardo’s actions paid dividends.

    Which direction will Brazil head?

    Like the U.S., Brazil is deeply fractured along left and right political lines. So it was no surprise that the local reactions to Trump’s announcement manifested along ideological camps.

    Despite their leader’s legal travails, Bolsonaro’s supporters remain very influential in politics, the media and among important economic areas, such as the agribusiness sector. Whether Trump’s decision will serve to help people rally around and in support of Lula and against a case of foreign interference is unclear. Lula’s initial pronouncement that Brazil would respond in kind was seen favorably among his supporters, though the opposition and many in the media pinned the blame on Lula for not being able to forge compromise with the Trump administration.

    Key industrialists in the powerful state of Sao Paulo, where Bolsonaro’s powerful ally Tarcisio de Freitas serves as governor, will be the first ones affected by the new tariffs. But the pain will likely spread into other activities, including in the countryside.

    And given that the bulk of the country’s agricultural exports go to China rather than to the U.S., the important question is whether these powerful exporters will act pragmatically and work with Lula to enlarge trade with the Asian giant and other countries, or whether they will continue to act ideologically and continue to support Bolsonaro’s enduring partnership with Trump against their own economic interests.

    Dialogue has been a hallmark of Brazil’s diplomacy, and even in the middle of these latest heated diplomatic exchanges, Lula reiterated his willingness to negotiate. It is unclear, though, whether the Trump adminstration’s actions in Latin America will be conducted on the basis of rationality and actual numbers, or if they will indeed bring back some old ideologically driven behaviors of picking sides in the internal political disputes of foreign nations. Should one consider at face value Trump’s latest letter, there is reason for concern.

  • Cleaner air in east Asia may have driven recent acceleration in global warming, our new study indicates

    Global warming has picked up pace since around 2010, leading to the recent string of record warm years. Why this is happening is still unclear, and among the biggest questions in climate science today. Our new study reveals that reductions in air pollution – particularly in China and east Asia – are a key reason for this faster warming.

    Cleanup of sulphur emissions from global shipping has been implicated in past research. But that cleanup only began in 2020, so it’s considered too weak to explain the full extent of this acceleration. Nasa researchers have suggested that changes in clouds could play a role, either through reductions in cloud cover in the tropics or over the North Pacific.

    One factor that has not been well quantified, however, is the effect of monumental efforts by countries in east Asia, notably China, to combat air pollution and improve public health through strict air quality policies. There has already been a 75% reduction in east Asian sulphur dioxide emissions since around 2013, and that cleanup effort picked up pace just as global warming began accelerating.

    Our study addresses the link between east Asian air quality improvements and global temperature, building on the efforts of eight teams of climate modellers across the world.

    We have found that polluted air may have been masking the full effects of global warming. Cleaner air could now be revealing more of the human-induced global warming from greenhouse gases.

    In addition to causing millions of premature deaths, air pollution shields the Earth from sunlight and therefore cools the surface. There has been so much air pollution that it has held human-induced warming in check by up to 0.5°C over the last century.

    With the cleanup of air pollution, something that’s vital for human health, this artificial sunshade is removed. Since greenhouse gas emissions have kept on increasing, the result is that the Earth’s surface is warming faster than ever before.

    Modelling the cleanup

    Our team used 160 computer simulations from eight global climate models. This enabled us to better quantify the effects that east Asian air pollution has on global temperature and rainfall patterns. We simulated a cleanup of pollution similar to what has happened in the real world since 2010. We found an extra global warming of around 0.07°C.

    While this is a small number compared with the full global warming of around 1.3°C since 1850, it is still enough to explain the recent acceleration in global warming when we take away year-to-year swings in temperature from natural cycles such as El Niño, a climate phenomenon in the Pacific that affects weather patterns globally.

    Based on long-term trends, we would have expected around 0.23°C of warming since 2010. However, we actually measured around 0.33°C. While the additional 0.1°C can largely be explained by the east Asian air pollution cleanup, other factors include the change in shipping emissions and the recent accelerated increase in methane concentrations in the atmosphere.

    Air pollution causes cooling by reflecting sunlight or by changing the properties of clouds so they reflect more sunlight. The cleanup in east Asian air pollution influences global temperatures because it reduces the shading effect of the pollution over east Asia itself. It also means less pollution is blown across the north Pacific, causing clouds in the east Pacific to reflect less sunlight.

    The pattern of these changes across the North Pacific simulated in our models matches that seen in satellite observations. Our models and temperature observations also show relatively strong warming over the North Pacific, downwind from east Asia.

    The main source of global warming is still greenhouse gas emissions, and a cleanup of air pollution was both necessary and overdue. This did not cause the additional warming but rather, removed an artificial cooling that has for a time helped shield us from some of the extreme weather and other well-established consequences of climate change.

    Global warming will continue for decades. Indeed, our past and future emissions of greenhouse gases will affect the climate for centuries. However, air pollution is quickly removed from the atmosphere, and the recent acceleration in global warming from this particular unmasking may therefore be short-lived.

  • University graduates in Ghana must serve society for a year – study suggests it’s good for national unity

    Source: ForeignAffairs4

    Source: The Conversation – Africa – By Arnim Langer, Professor, KU Leuven

    Almost 70 years after independence was gained across the continent, many African countries continue to face the complex task of managing ethnic diversity and building national cohesion. National cohesion is a broad and often abstract concept. It refers to the extent to which people within a country share a sense of common purpose and belonging. It is often reflected in the strength of national identities and the degree of pride individuals feel in being part of the nation.

    The fact that borders in colonial Africa were drawn in the late 19th century to the early 20th century by European powers without regard for ethnic and cultural realities and histories meant that post-colonial African governments had to develop a sense of national consciousness and belonging.

    To address this task, many African countries have made efforts to promote a shared national identity which could bridge ethnic and regional divides. Governments have experimented with a diverse range of policies: promoting national languages, establishing civic education, celebrating national holidays, and reforming state institutions. Other measures have included abolishing traditional kingdoms, redistributing land, renaming capital cities, compulsory military service, and national youth service programmes.

    Research into the effectiveness of these African initiatives has been limited and inconclusive. In recently published research, researchers at the Centre for Research on Peace and Development at KU Leuven addressed this gap by analysing the impact of Ghana’s National Service Scheme. Our research shows that, under certain conditions, participation in this programme can meaningfully enhance feelings of national belonging.

    Ghana’s experience with national service

    Established in 1973, Ghana’s National Service Scheme requires university graduates to spend one year serving in diverse roles throughout the country. This sometimes takes them to regions far from their homes.

    While Ghana is widely regarded as a model for the peaceful management of ethnic diversity, the establishment of the National Service Scheme in 1973 was necessary. It was partly a response to the deep regional and ethnic divisions that marked the country’s early postcolonial period. Notably, in the years leading up to the scheme’s introduction, political rivalry between Ashanti and Ewe elites played a significant role in the country’s political instability.

    Initially designed to counteract such ethnic divisions, the scheme continues to engage very large numbers of graduates each year. Over 100,000 were deployed in 2025. The programme aims not only to strengthen national cohesion, but also to promote manpower development and address key social challenges. These include unemployment, illiteracy and poverty.

    Participants are deployed across a range of sectors, including education, healthcare, agriculture and public administration. While the vast majority of participants are assigned to teaching roles in primary or secondary schools or to positions in healthcare institutions, others take on administrative roles within government agencies or the private sector. These deployments are meant to expose them to different communities and foster intergroup contact under conditions that promote social bonding and reduce prejudice.

    But can national service also contribute towards fostering stronger feelings of national belonging?

    To answer this question, we conducted a large-scale panel survey among almost 3,000 service personnel. They had participated in the scheme between August 2014 and September 2016. The participants were surveyed three times: before their deployment and again within weeks after completing their national service.

    The survey was aimed at examining their feelings of national pride before, during, and after their year of national service. Our study provides compelling evidence that national service significantly boosts participants’ feelings of national pride and belonging.

    We found that the mechanism behind this impact lies in intergroup contact. This is described as positive, meaningful interactions between individuals from diverse ethnic and regional backgrounds. Participants who reported frequent and meaningful interactions, including developing new friendships and gaining deeper knowledge of other cultural groups, showed the most significant increases in their sense of national pride.

    Importantly, the greatest improvements were observed among participants who initially identified less strongly with the nation.

    We further found that the positive effects of participation were not short-lived. It persisted well beyond the year of service.

    Key takeaways for policymakers

    Governments aiming to strengthen national identity through youth service programmes should consider four key lessons from Ghana’s experience.

    Mandatory participation is crucial. Voluntary schemes tend to attract individuals who are already inclined towards inter-ethnic harmony. This limits their broader societal impact. Ghana’s mandatory approach ensures that a wide and diverse range of participants are included. This enhances the programme’s reach and effectiveness.

    Structured interactions must be actively promoted. Simply placing people from different backgrounds together is not enough. Successful programmes, such as Ghana’s, intentionally create opportunities for meaningful engagement. These structured interactions help participants develop lasting relationships and deepen their understanding of other cultures.

    Youth should be engaged during formative years. Recent graduates are at a stage in life when attitudes and identities are still forming. National service programmes that target this age group can have a lasting influence. Especially on how young people perceive national unity and their role within it.

    Diverse placements are essential. National service programmes should deploy participants in settings that are diverse. The geographical location is of secondary importance. Exposure to diverse settings will challenge assumptions and broaden perspectives. It will also foster stronger national bonds across ethnic and regional lines.

    Why national service pays off in the long run

    National youth service programmes, when well-designed and properly managed, are a promising yet underused tool for promoting national unity in Africa’s ethnically diverse societies. These initiatives can create meaningful opportunities for young people to engage across regional and ethnic lines. This helps to build trust, civic responsibility, and a shared sense of national identity.

    Yet, in recent decades, many of these programmes have been scaled back or discontinued across the continent. Examples are Botswana, Tanzania, Zimbabwe and Zambia. The main reason? Cost. Governments have often viewed the logistical and financial demands of deploying tens of thousands of graduates each year as unsustainable. But this short-term budget logic misses the bigger picture.

    Ghana’s scheme shows what’s possible. In recent years, the scheme’s deployment figures have reached record highs. It is now common for around 100,000 national service personnel to be mobilised in a single service year. The positive outcomes observed in Ghana offer clear, evidence-based lessons for policymakers across the continent. Investing in national service is not just a cost – it’s a commitment to a more united future.

  • 4 things every peace agreement needs – and how the DRC-Rwanda deal measures up

    Source: ForeignAffairs4

    Source: The Conversation – Africa (2) – By Philipp Kastner, Senior Lecturer in International Law, The University of Western Australia

    The governments of the Democratic Republic of the Congo (DRC) and Rwanda concluded a peace treaty in June 2025, aimed at ending a decades-long war in eastern DRC. The United Nations welcomed the agreement as “a significant step towards de-escalation, peace and stability” in the region.

    I have analysed several different peace negotiations and agreements. It’s important to distinguish between what’s needed to get warring parties to the table, and what’s eventually agreed on. In this article, I examine whether the DRC-Rwanda deal has got the four essential components that usually signal that an agreement will hold.

    Two broad points about peace agreements, first – and one particular complication in the DRC-Rwanda case.

    Firstly, one agreement is rarely enough to resolve a complex conflict. Most deals are part of a series of agreements, sometimes between different actors. They often mention previously concluded ones, and will be referred to by subsequent ones.

    Secondly, peace is a process, and requires broad and sustained commitment. It is essential that other actors, like armed groups, are brought on board. Importantly, this also includes civil society actors. An agreement will be more legitimate and effective if different voices are heard during negotiations.

    One major complication in relation to the DRC-Rwanda deal is that the United States has been the prime broker. But rather than acting as a neutral mediator trying to bring about peace, Washington seems to be pursuing its own economic interests. This does not bode well.

    There is no simple recipe for a good peace agreement, but research shows that four elements are important: a serious commitment from the parties, precise wording, clear timelines and strong implementation provisions.

    What underpins a good agreement

    First, the parties need to be serious about the agreement and able to commit to its terms. It must not be used as a cover to buy time, re-arm or pursue fighting. Moreover, lasting peace cannot be made exclusively at the highest political level. Agreements that are the result of more inclusive processes, with input by and support from the communities concerned, have a higher success rate.

    Second, the agreement must address the issues it aims to resolve, and its provisions must be drafted carefully and unambiguously. When agreements are vague or silent on key aspects, they are often short-lived. Previous experiences can guide peace negotiators and mediators in the drafting process. Peace agreement databases established by the United Nations and academic institutions are a useful tool for this.

    Third, clear and realistic timelines are essential. These can concern the withdrawal of armed forces from specified territories, the return of refugees and internally displaced persons, and the establishment of mechanisms providing reparations or other forms of transitional justice.

    Fourth, an agreement should include provisions on its implementation. External support is usually helpful here. Third states or international organisations, liked the United Nations and the African Union, can be mandated to oversee this phase. They can also provide security guarantees or even deploy a peacekeeping operation. What is crucial is that these actors are committed to the process and don’t pursue their own interests.

    DRC and Rwanda sign a US-brokered peace deal: what are the chances of its success?


    To know what to realistically expect from a specific peace agreement, it’s important to understand that such agreements can take very different forms. These range from pre-negotiation arrangements and ceasefires to comprehensive peace accords and implementation agreements.

    A lasting resolution of the conflict should not be expected when only a few conflict parties have concluded a temporary ceasefire.

    The DRC-Rwanda agreement: an important step with lots of shortcomings

    It’s difficult to tell at this point how serious the DRC and Rwanda are about peace, and if their commitment will be enough.

    Their assertion that they will respect each other’s territory and refrain from acts of aggression is certainly important.

    But Rwanda has a history of direct military activities in the DRC since the 1990s. And the treaty only includes rather vague references to the “disengagement of forces/lifting of defensive measures by Rwanda”. It doesn’t specifically mention the withdrawal of the reportedly thousands of Rwandan troops deployed to eastern DRC.

    The Paul Kagame-led Rwandan government has also supported Tutsi-dominated armed groups in the DRC since the Rwandan genocide in 1994. The Mouvement du 23 Mars (M23) is the current primary military actor in eastern DRC. But the agreement between the governments of DRC and Rwanda didn’t include the M23 or other groups. The two governments only commit themselves to supporting the ongoing negotiations between the DRC and the M23 facilitated by Qatar.

    The agreement also foresees the “neutralisation” of another armed group, the Hutu-dominated Forces Démocratiques pour la Libération du Rwanda (FDLR). This group claims to protect Rwandan Hutu refugees in the DRC, but is considered “genocidal” by the Rwandan government. The group has reacted to this plan by calling for a political solution and a more inclusive peace process.

    What’s needed

    The DRC-Rwanda agreement includes provisions that are vital to the people most affected by the conflict, such as the return of the millions of people displaced because of the fighting in eastern DRC. But it does not address other key issues.

    For instance, aside from a general commitment to promote human rights and international humanitarian law, there is no reference to the widespread violations of human rights and war crimes reportedly committed by all sides. These include summary executions, and sexual and gender-based violence, including violence against children.

    Some form of justice and reconciliation mechanism to deal with such large-scale violence should be considered in this situation, as for instance in the fairly successful 2016 agreement between the Colombian government and the Revolutionary Armed Forces of Colombia – People’s Army (FARC). This could contribute to preventing further violations as it sends a clear signal that committing crimes will not be rewarded. It also helps the population heal and gives peace a better chance.

    There is no single model for this, and so-called transitional justice (defined as the “range of processes and mechanisms associated with a society’s attempts to come to terms with a legacy of large-scale past abuses, in order to ensure accountability, serve justice and achieve reconciliation”) remains highly controversial. For instance, insisting on war crimes trials can be seen as endangering a fragile peace process.

    But peace agreements across the world, from Libya to the Central African Republic, have over past decades moved away from blanket amnesties. They have increasingly included provisions to ensure accountability, especially for serious crimes. The DRC-Rwanda deal is silent on these questions.

    A twist in the tale

    The DRC-Rwanda deal is complicated by Washington’s role and pursuit of economic interests.

    The two states agreed to establish a joint oversight committee, with members of the African Union, Qatar and the United States. It foresees a “regional economic integration framework”, which has been criticised as opening the door for foreign influence in the DRC’s rich mineral resources. The country is the world’s largest producer of cobalt, for instance, which is essential for the renewable energy sector.

    Such a neocolonial “peace for exploitation bargain” does not send a positive signal. And it will probably not contribute to ending an armed conflict that has been fuelled by the exploitation of natural resources.

  • Bullying, violence and vandalism in primary school: study explores a growing crisis in South Africa

    Source: ForeignAffairs4

    Source: The Conversation – Africa – By Julie Shantone Rubbi Nunan, Senior Lecturer in the Department of Early Childhood Education and Development, University of South Africa

    South African primary schools are facing a crisis. Every day, learners fight, bully, destroy property, and intimidate other learners and teachers, turning what should be safe spaces into places of fear and mistrust.

    Research shows that learner behaviour frequently involves violence, bullying and vandalism (damage to school property) that threatens the safety of both learners and staff.

    The media usually report only serious cases of violence, but schools and teachers face challenging and dangerous behaviour every day that often goes unreported. This underreporting is not unique to South Africa; it’s a challenge seen in other countries too.

    Research shows that this kind of behaviour disrupts teaching and learning, leading to poor learner performance and school dropouts.

    Teachers frequently face aggression and intimidation from learners, which undermines their ability to teach effectively. They feel unsafe and frustrated when learners act aggressively, and this problem worsens when parents protect their children’s bad behaviour instead of addressing it.

    Violence, bullying, and damage to school property don’t just cause harm to learners and teachers. They also cost schools money to repair the damage and cause emotional trauma and suffering for victims and their families.

    Given these realities, it is important to carefully explore the lived experiences of teachers, school leaders and caretakers to fully understand the severity and complexity of challenging learner behaviour. This understanding is essential for developing effective policies and interventions aimed at restoring safety and improving learning environments in South African primary schools.

    As part of a wider study of challenging learner behaviour, I interviewed 21 participants from three primary schools in Durban, South Africa. It was a qualitative case study, in which the small sample size was well-suited and provided relevant and credible information on challenging learner behaviour. Thematic analysis was appropriate for identifying patterns and themes for further exploration.

    The aim was to probe the participants’ perspectives to understand how learners’ challenging behaviour is experienced in primary schools. I wanted to know more about how behaviour stemming from children’s homes and environments, playing out at school, was affecting teachers and the overall school climate.

    The interviews indicated that teachers were unhappy and wanting to quit the profession, learner victims faced constant fear and distress, and caretakers felt degraded. If this is a sign of how teachers, children and caretakers are feeling around South Africa, it points to the need for ways to reduce their stress.

    Voices from schools

    The schools in my study are located in semi-urban areas within the same district and serve learners from grade R (about age 5) to grade 7 (about age 12). The surrounding communities face high levels of unemployment, domestic violence, and various social challenges.

    Fifteen teachers, three governors, and three caretakers shared their experiences through interviews, enabling open discussion and deeper insights. Consistency across school sites supported the trustworthiness of the findings. Ethical guidelines were followed throughout.

    Across the three schools, participants described an environment where serious learner misconduct was a common, everyday problem.

    Teachers, governors, and caretakers reported daily disruptions that affected teaching, learning and emotional wellbeing. Aggression and violence were constant. Learners engaged in physical fights – punching, kicking, and using sharp objects like pencils and knives. These were not minor scuffles but incidents that caused serious injuries. Teachers were also threatened, shouted at, and occasionally physically harmed.

    Bullying was widespread, both verbal and physical. Learners harassed peers through name-calling, exclusion, extortion and intimidation, often in unsupervised spaces like toilets and tuckshops. Victims lived in fear, while teachers struggled to maintain discipline and protect vulnerable learners.

    Vandalism and property damage were routine. Learners tore up textbooks, damaged desks and windows, defaced walls with vulgar graffiti, and clogged toilets with rubbish. Caretakers faced degrading tasks like cleaning and scrubbing faeces and graffiti off the walls. The costs of repairing damage strained already limited school budgets.

    Adding to the tension, gang-like behaviour emerged. Small groups banded together to provoke fights, intimidate others, and sometimes fuel unrest rooted in xenophobia or local politics, creating fear, uncertainty and division among learners.

    Some incidents had gendered and criminal implications, including the reporting of boys violating the privacy and rights of other boys in the school toilets, and girls being inappropriately touched and harassed. This contributed to emotional trauma and, in some cases, learner dropout – especially among girls. The United Nations Children’s Fund posits that school violence contributes to girls dropping out of school. The dropout rate is a concern in South Africa.

    Stealing and lying were common. Learners stole from classmates, teachers, and school offices, often without remorse, and frequently lied or blamed others when confronted, further eroding trust and accountability.

    Dealing with unruly behaviour among schoolchildren in a tumultuous world


    Many participants believed learners expressed unspoken pain or mirrored violence and instability seen at home and in their communities. According to social cognitive theory, such behaviours are learned. Children exposed to violence, neglect, or chaos often replicate these actions in school. Without consistent guidance, role models, or consequences, the cycle intensifies.

    Moving forward

    In short, these schools are no longer safe havens for learning – they are in crisis. Without urgent and effective intervention, the very mission of basic education – and the wellbeing of children – is at risk.

    Primary schools depend on governing authorities and communities for their safety and success. Stakeholders must take collective action to reclaim schools as safe learning spaces.

    Governing authorities should address the issues raised by reviewing policies and implementing support programmes, including counselling, family-school partnerships, and teacher training to handle challenging behaviour in positive and sustainable ways.

  • How Eurostack could offer Canada a route to digital independence from the United States

    Source: ForeignAffairs4

    Source: The Conversation – Canada – By Ted Palys, Professor of Criminology, Associate Member of Dept. of Indigenous Studies, Simon Fraser University

    The contemporary internet has been with us since roughly 1995. Its current underlying economic model — surveillance capitalism — began in the early 2000s, when Google and then Facebook realized how much our personal information and online behaviour revealed about us and claimed it for themselves to sell to advertisers.

    Perhaps because of Canada’s proximity to the United States, coupled with its positive shared history with the U.S. and their highly integrated economies, Canada went along for that consumerist ride.

    The experience was different on the other side of the Atlantic. The Stasi in the former East Germany and the KGB under Josef Stalin maintained files on hundreds of thousands of citizens to identify and prosecute dissidents.

    Having witnessed this invasion of privacy and its weaponization first-hand, Europe has been far ahead of North America in developing protections. These include the General Data Protection Regulation and the Law Enforcement Directive, with protection of personal data also listed in the European Union’s Charter of Fundamental Rights.

    Canada clearly took too much for granted in its relationship with the U.S. Suddenly, Canada is being threatened with tariffs and President Donald Trump’s expressed desire to make Canada the 51st American state.

    This has fuelled the motivation of Canada both internally and in co-operation with western European governments to seek greater independence in trade and military preparedness by diversifying its relationships.

    Prime Minister Mark Carney has begun promoting “nation-building projects,” but little attention has been paid to Canada’s digital infrastructure.




    Read more:
    How Canadian nationalism is evolving with the times — and will continue to do so


    Three areas of concern

    Three recent developments suggest Canada would be well-advised to start paying close attention:

    1. The current U.S. administration has raised concerns about its reliability as a partner and friend to Canada. Most of the concerns raised in Canada have been economic. However, Curtis McCord, a former national security and technology researcher for the Canadian government, has said the current situation has created vulnerabilities for national security as well:

    “With Washington becoming an increasingly unreliable ally, Mr. Carney is right to look for ways to diversify away from the U.S. But if Canada wants to maintain its sovereignty and be responsible for its national security, this desire to diversify must extend to the U.S. domination of Canada’s digital infrastructure.”

    2. Silicon Valley is exhibiting a newfound loyalty to Trump. The photo of the “broligarchy” at Trump’s inauguration spoke volumes, as their apparent eagerness to appease the president brings the data gathered by the internet’s surveillance-based economy under state control.

    3. Trump’s recent executive order entitled “Stopping waste, fraud and abuse by eliminating information silos” is alarming. The order became operational when the Trump administration contracted with Palantir, a company known for its surveillance software and data analytics in military contexts. Its job? To combine databases from both the state and federal levels into one massive database that includes every American citizen, and potentially any user of the internet.

    Combining multiple government databases is concerning. Combining them with all the personal data harvested by Silicon Valley and providing them to a government showing all the hallmarks of an authoritarian regime sounds like Big Brother has arrived.

    Civil liberties groups such as the Electronic Freedom Foundation, academics and even former Palantir employees have raised alarms about the possibilities for abuse, including the launch of all the vendettas Trump and his supporters have pledged to undertake.

    The appeal of Eurostack

    European governments have attempted to rein in Silicon Valley’s excesses for years. Trump’s re-election and his moves toward potentially weaponizing internet data have further boosted Europe’s resolve to move away from the U.S.-led internet.

    One newer effort is Eurostack. A joint initiative involving academics, policymakers, companies and governments, it envisions an independent digital ecosystem that better reflects European values — democratic, sovereign, inclusive, transparent, respectful of personal privacy and innovation-driven.

    Spokesperson Francesca Bria explains the “stack” arises from the idea that a digitally sovereign internet needs to have European control from the ground up.

    Bria discusses Eurostack in May 2025. (re:publica)

    That includes the acquisition of raw materials and manufacture and operation of the physical components that comprise computers and servers; the cloud infrastructure that has the processing power and storage to be operational at scale; the operating systems and applications that comprise the user interface; the AI models and algorithms that drive services and its policy and governance framework.

    Prospective gains to Europe are considerable. They include greater cybersecurity, promoting innovation, keeping high-end creative jobs in Europe, promoting collaboration on equitable terms and creating high-skilled employment opportunities.

    Canada receives no mention in the Eurostack proposal to date, but the project is still very much in the developmental phase. Investment so far is in the tens of millions instead of the billions it will require.

    Canada has a lot to offer and to gain from being part of the Eurostack initiative. With the project still taking shape, now is the perfect time to get on board.

  • Listening to nonhumans: What music can teach about humanity’s relationships with nature and the divine

    As someone who teaches and researches music and religion, I’ve always been curious about inspiration and how it connects humans to other beings.

    Musicians can be inspired by great artists, living and dead; by technologies that expand their experience, like artist Brian House’s macrophones that capture low-frequency infrasound; by plants and animals; and by the unseen, unheard presence of the supernatural. After all, the word inspiration is rooted in the Latin for “breathing in.” Often, it was associated with spiritual or divine influence – inspiration coming from other realms.

    In my research and teaching, recognizing non-human beings is ethically important and an act of intellectual humility. It ensures that I honor other people’s religious and musical experiences, and it admits that we cannot know precisely what they know. One person’s reality may not translate to our own understanding.

    That’s what led me to design this course: “Music, Sound and Research with Non-Humans.”

    What does the course explore?

    The “with” in the course title is key: I want students to learn about how human knowledge exists in relationship with non-humans. To do this, we read and listen widely.

    In research using Actor-Network Theory, for example, relationships between humans and non-humans are central: musicians, scientists and their instruments; you and your smartphone; humans and gods. In each case, humans and non-humans are both considered actors – beings that make a real difference in the world.

    Music scholar Peter McMurray uses a similar lens in his work on Alevi “semah” ritual, which involves music, movement and poetry. Alevism is a mystical tradition of Islam in Turkey that has long faced discrimination. Some of the sung poetry used for semah is inspired by sacred animals, such as cranes. In semah, participants experience cranelike flight through music and dance, which are central to Alevi ritual.

    Dance is an important part of Alevi semah.

    Or consider traditions of chanting revealed in texts like the Quran, which means “recitation” in Arabic. Spiritually, the purpose is not only to learn the scripture, but to draw closer to its sonic essence. Recitation recalls moments of encounter between humans and the divine, most important being the Prophet Muhammad receiving the Quran through the Angel Gabriel.

    We also look beyond music, to everything from medicine and biology to economics, to study relationships between humans and non-humans. One of our favorite readings, for example, is “The Mushroom at the End of the World” by anthropologist Anna Lowenhaupt Tsing. This is a rich ethnographic account of the relationships between humans and matsutake mushrooms, which are highly prized in Japanese cuisine: the piney forests where matsutake grow, the human activities that make them thrive, the foragers who collect them, and the global markets where they are traded.

    My students Luana Espinoza and Sofia Ahmed Seid describe our course as exploring a kind of symbiosis: the word biologists use to describe close, often mutually beneficial, relationships between species.

    What’s a critical lesson from the course?

    This course readies students to confront serious, challenging forms of intellectual diversity, considering how the possibilities of different truths and paradigms might inform their research.

    Both students this semester are science majors working on senior theses: Espinoza in chemistry and Seid in neuroscience. By reading and listening to others’ accounts of human and non-human relationships, they say they no longer feel required to leave an essential part of themselves at the classroom door.

    Music and sound bridge the physical and metaphysical, the natural and the supernatural. Because of this, they are invaluable for encountering complex truths.

  • Is there any hope for the internet?

    Source: ForeignAffairs4

    Source: The Conversation – USA (2) – By Aarushi Bhandari, Assistant Professor of Sociology, Davidson College

    Hate and mental illness fester online because love and healing seem to be incompatible with profits. Ihor Lukianenko/iStock via Getty Images

    In 2001, social theorist bell hooks warned about the dangers of a loveless zeitgeist. In “All About Love: New Visions,” she lamented “the lack of an ongoing public discussion … about the practice of love in our culture and in our lives.”

    Back then, the internet was at a crossroads. The dot-com crash had bankrupted many early internet companies, and people wondered if the technology was long for this world.

    The doubts were unfounded. In only a few decades, the internet has merged with our bodies as smartphones and mined our personalities via algorithms that know us more intimately than some of our closest friends. It has even constructed a secondary social world.

    Yet as the internet has become more integrated in our daily lives, few would describe it as a place of love, compassion and cooperation. Study after study describe how social media platforms promote alienation and disconnection – in part because many algorithms reward behaviors like trolling, cyberbullying and outrage.

    Is the internet’s place in human history cemented as a harbinger of despair? Or is there still hope for an internet that supports collective flourishing?

    Algorithms and alienation

    I explore these questions in my new book, “Attention and Alienation.”

    In it, I explain how social media companies’ profits depend on users investing their time, creativity and emotions. Whether it’s spending hours filming content for TikTok or a few minutes crafting a thoughtful Reddit comment, participating on these platforms takes work. And it can be exhausting.

    Even passive engagement – like scrolling through feeds and “lurking” in forums – consumes time. It might feel like free entertainment – until people recognize they are the product, with their data being harvested and their emotions being manipulated.

    Blogger, journalist and science fiction writer Cory Doctorow coined the term “enshittification” to describe how experiences on online platforms gradually deteriorate as companies increasingly exploit users’ data and tweak their algorithms to maximize profits.

    For these reasons, much of people’s time spent online involves dealing with toxic interactions or mindlessly doomscrolling, immersed in dopamine-driven feedback loops.

    This cycle is neither an accident nor a novel insight. Hate and mental illness fester in this culture because love and healing seem to be incompatible with profits.

    Care hiding in plain sight

    In his 2009 book “Envisioning Real Utopias,” the late sociologist Erik Olin Wright discusses places in the world that prioritize cooperation, care and egalitarianism.

    Wright mainly focused on offline systems like worker-owned cooperatives. But one of his examples lived on the internet: Wikipedia. He argued that Wikipedia demonstrates the ethos “from each according to ability, to each according to need” – a utopian ideal popularized by Karl Marx.

    Wikipedia still thrives as a nonprofit, volunteer-ran bureaucracy. The website is a form of media that is deeply social, in the literal sense: People voluntarily curate and share knowledge, collectively and democratically, for free. Unlike social media, the rewards are only collective.

    There are no visible likes, comments or rage emojis for participants to hoard and chase. Nobody loses and everyone wins, including the vast majority of people who use Wikipedia without contributing work or money to keep it operational.

    Building a new digital world

    Wikipedia is evidence of care, cooperation and love hiding in plain sight.

    In recent years, there have been more efforts to create nonprofit apps and websites that are committed to protecting user data. Popular examples include Signal, a free and open source instant messaging service, and Proton Mail, an encrypted email service.

    These are all laudable developments. But how can the internet actively promote collective flourishing?

    What if Wikipedia were less the exception, and more the norm?

    In “Viral Justice: How We Grow the World We Want,” sociologist Ruha Benjamin points to a way forward. She tells the story of Black TikTok creators who led a successful cultural labor strike in 2021. Many viral TikTok dances had originally been created by Black artists, whose accounts, they claimed, were suppressed by a biased algorithm that favored white influencers.

    TikTok responded to the viral #BlackTikTokStrike movement by formally apologizing and making commitments to better represent and compensate the work of Black creators. These creators demonstrated how social media engagement is work – and that workers have the power to demand equitable conditions and fair pay.

    This landmark strike showed how anyone who uses social media companies that profit off the work, emotions and personal data of their users – whether it’s TikTok, X, Facebook, Instagram or Reddit – can become organized.

    Meanwhile, there are organizations devoted to designing an internet that promotes collective flourishing. Sociologist Firuzeh Shokooh Valle provides examples of worker-owned technology cooperatives in her 2023 book, “In Defense of Solidarity and Pleasure: Feminist Technopolitics in the Global South.” She highlights the Sulá Batsú co-op in Costa Rica, which promotes policies that seek to break the stranglehold that negativity and exploitation have over internet culture.

    “Digital spaces are increasingly powered by hate and discrimination,” the group writes, adding that it hopes to create an online world where “women and people of diverse sexualities and genders are able to access and enjoy a free and open internet to exercise agency and autonomy, build collective power, strengthen movements, and transform power relations.”

    In Los Angeles, there’s Chani, Inc., a technology company that describes itself as “proudly” not funded by venture capitalists. The Chani app blends mindfulness practices and astrology with the goal of simply helping people. The app is not designed for compulsive user engagement, the company never sells user data, and there are no comments sections.

    No comments

    What would social media look like if Wikipedia were the norm instead of an exception?

    To me, a big problem in internet culture is the way people’s humanity is obscured. People are free to speak their minds in text-based public discussion forums, but the words aren’t always attached to someone’s identity. Real people hide behind the anonymity of user names. It isn’t true human interaction.

    In “Attention and Alienation,” I argue that the ability to meet and interact with others online as fully realized, three-dimensional human beings would go a long way toward creating a more empathetic, cooperative internet.

    When I was 8 years old, my parents lived abroad for work. Sometimes we talked on the phone. Often I would cry late into the night, praying for the ability to “see them through the phone.” It felt like a miraculous possibility – like magic.

    I told this story to my students in a moment of shared vulnerability. This was in 2020 during the COVID-19 pandemic, so the class was taking place over videoconferencing. In these online classes, one person talked at a time. Others listened.

    It wasn’t perfect, but I think a better internet would promote this form of discussion – people getting together from across the world to share the fullness of their humanity.

    Efforts like Clubhouse have tapped into this vision by creating voice-based discussion forums. The company, however, has been criticized for predatory data privacy policies.

    What if the next iteration of public social media platforms could build on Clubhouse? What if they brought people together and showcased not just their voices, but also live video feeds of their faces without harvesting their data or promoting conflict and outrage?

    Raised eyebrows. Grins. Frowns. They’re what make humans distinct from increasingly sophisticated large language models and artificial intelligence chatbots like ChatGPT.

    After all, is anything you can’t say while looking at another human being in the eye worth saying in the first place?

    When Zohran Mamdani announced his candidacy for mayor of New York City, political observers noted his progressive platform and legislative record. But understanding the Democratic candidate’s background requires examining the rich cultural tapestry woven into his very surname: Mamdani.

    He takes the name from his father, Mahmood Mamdani, a prominent academic who was raised in Uganda and whose work focuses on postcolonial Uganda. I studied the history of the Khoja community for my doctoral work and have helped develop Khoja studies as an academic discipline. The Mamdani surname tells a story of migration, resilience and community-building that spans centuries and continents.

    The Khoja history

    Mamdanis in Uganda belong to the Khoja community, a South Asian Muslim merchant caste, that shaped economic development across the western Indian Ocean for centuries.

    The name originates from greater Sindh, a region in South Asia that today includes southeastern Pakistan and Kachchh in western India.

    Its etymology is twofold. Mām is an honorific title in Kachchhi and Gujarati languages, meaning kindness, courage and pride. Māmadō is a local version of the name Muhammad that often appeared in surnames in Hindu castes that converted to Islam, such as the Memons.

    The Khoja were categorized by the British in the early 19th century as “Hindoo Mussalman” because their traditions spanned both religions.

    Over time, the Khoja came to be identified only as Muslim and then primarily as Shiite Muslim. Today, the majority of Khoja are Ismaili: a branch of Shiite Islam that follows the Aga Khan as their living imam.

    The Mamdani family, however, is part of the Twelver community of Khoja, whose Twelfth Imam is believed to be hidden from the world and only emerges in times of crisis. Twelvers believe he will help usher in an age of peace during end times.

    Around the late 18th century, the Khoja helped export textiles, manufactured goods, spices and gems from the Indian subcontinent to Arabia and East Africa. Through this Western Indian Ocean trading network, they imported timber, ivory, minerals and cloves, among other goods.

    Khoja family firms were built on kinship networks and trust. They built networks of shops, communal housing and warehouses, and extended credit for thousands of miles, from Zanzibar in Tanzania to Bombay – now Mumbai – on the western coast of India.

    Cousins and brothers would send money and goods across the ocean with only a letter. The precarious nature of trade in this period meant that families also served as insurance for each other. In times of wealth, it was shared; in times of disaster, help was available.

    Khoja contributions in Africa

    The Khoja became instrumental in building the commercial infrastructure of eastern, central and southern Africa. But the Khoja contribution to the development of Africa extended far beyond trade.

    In the absence of colonial investment in public infrastructure, they helped build institutions that formed the foundation of the modern nation-states that emerged after colonization. The institutions both facilitated trade and established permanent communities.

    For example, the first dispensary and public school in Zanzibar were constructed by a Khoja magnate, Tharia Topan, who made his wealth through the ivory and clove trades. Topan eventually became so prominent that he was knighted by Queen Victoria in 1890 for his service to the British Empire in helping to end slavery in East Africa.

    The Khoja community continues to invest in East Africa. The most famous example is the Aga Khan Development Network, whose hospitals and schools operate in 30 countries. In places such as Kenya, Uganda and Tanzania, they are considered the best.

    Khoja in Uganda

    Like in other parts of Africa, the Khoja settled in Uganda as a liaison business community to develop a market to serve both African and European needs. The linguistic and cultural knowledge, developed over centuries, helped facilitate business despite the challenges of colonization.

    However, in 1972, Ugandan dictator Idi Amin expelled all Asians – approximately 80,000 – forcing families like the Mamdanis into exile. These included indentured laborers, who were brought in to help build the railroad and farm during the British colonial period, and free traders, like the Mamdani family.

    Amin saw them all as the same and famously said: “Asians came to Uganda to build the railway. The railway is finished. They must leave now.”

    The experience was a bitter one. Families lost everything, and many left with only the clothes on their backs.

    Mahmood Mamdani, who came from a Khoja merchant family, was 26 when he was exiled. Yet, unlike most Ugandan Asians, he chose to go back. At Makerere University in Kampala, Uganda’s capital, Mamdani set up the Institute for Social Research, which helped to provide rigorous social science training to Ugandan researchers trying to improve their society.

    While the earlier generations of the Khoja tended to choose business or adjacent professions, such as accounting, the subsequent generations – particularly those educated in the West – embraced the knowledge economy as professionals, academics and nonprofit leaders.

    Several of Mahmood Mamdani’s generation of Khoja academics conducted path-breaking work on Afro-Asian solidarity – a way of thinking about the world beyond colonial categories, such as the category of religion as a separate domain from the secular. These scholars, such as Tanzania’s Issa Shivji and Abdul Sheriff, worked on creating solidarity among the newly independent states of the Global South.

    Mahmood Mamdani is known for his influential post-9/11 academic work, “Good Muslim, Bad Muslim,” which examined how Muslim identities are stereotyped. He argued that these identities are complex and varied, shaped by accumulated history and present experiences.

    Interfaith identity

    The Khoja community – known globally as the Khoja Shia Ithnasheri Muslim Community – has developed strong transnational connections. Today, they are concentrated in the United Kingdom, Canada, United States and France. However, Khoja can be found in almost any country in the world. In 2013, I met members of the community in Hong Kong.

    The Khoja community plays an important role in interfaith dialogue and global development initiatives. A prominent Ismaili Khoja, Eboo Patel, the founder of Interfaith America, has dedicated his life to pluralism and mutual understanding through building up civil society.

    Zohran Mamdani’s mother, acclaimed filmmaker Mira Nair, is Hindu by birth. This interfaith marriage exemplifies the flexibility, diversity and tolerance of Khoja Islam, which has historically navigated between Hindu and Islamic traditions.

    Whether Mamdani’s policies prove practical remains to be seen, but his background offers something valuable: a deep understanding of how communities build resilience across generations and geographies.

    Who was the first pirate? – Yandel R., age 11, Lakewood Ranch, Florida


    When most people imagine a pirate, they picture actor Johnny Depp playing the mad but likable swashbuckler Jack Sparrow, captain of the sailing ship the Black Pearl.

    Depp’s pirate portrayal was inspired by seafaring bandits in older make-believe tales, such as Long John Silver in “Treasure Island,” Captain Hook in “Peter Pan,” or sailor Edmond Dantès in “The Count of Monte Cristo.”

    Pirates in these stories were mischievous but also glamorous, courageous and mostly kindhearted. They wore flashy costumes. They had missing limbs, like Captain Cook’s iron hook for a left hand and Long John Silver’s wooden peg leg. They buried treasure chests of gold and silver, forced enemies to walk the plank and had talking parrots as shipboard companions. They flew the Jolly Roger skull and crossbones flag from the ship’s mast to frighten enemies. The new Netflix series “One Piece,” which is based on a Japanese comic book, continues this popular depiction of pirates.

    While fun, these portrayals of pirates are mostly invented.

    I’m a political scientist who studies modern-day commerce raiding: robbing of private cargo vessels on the high seas. I’m interested in where it happens in the world, who does it and what can be done to stop it. My research finds today’s pirates to be less like swashbuckling Jack Sparrow and more like regular old thieves.

    Pirates in the ancient world

    Since pirates have been around for as long as people have moved things by boat, it is hard to pin down the very first pirate.

    But archaeological evidence shows that boatbuilding goes all the way back to the ancient Egyptians, who used boats made from papyrus reeds as early as 6,000 years ago. These vessels likely carried valuable goods up and down the Nile River, and where valuable goods can be found, you can usually find thieves too. In fact, researchers know that pirates – basically just thieves on the water – targeted these river boats, because Egyptian pharaohs left records grumbling about pirates and their widespread pillaging.

    By 3,500 years ago, thieves were using sailing vessels to raid coastal towns and villages in and around the Nile Delta, as well as the Aegean and Adriatic basins. Attacking ships far from land on the high seas and stealing the cargo was a logical next step in the tactics of seafaring raiders.

    As trade increased across the Mediterranean Sea, boats carrying valuable cargo, such as pottery, silk, glass, spices and metals, became the targets of ancient pirates. Given the worth of these goods, pirate attacks became widespread across the ancient Mediterranean Sea. With money from the Roman senate and strong effort by a military leader named Pompey, the Roman navy worked hard to stop the pirates – and for a while it did.

    The earliest named pirate?

    The first mention of a pirate by name may have been in a Greek history book written in the fifth century BCE by an ancient historian named Herodotus.

    He briefly describes the adventures of a naval commander by the name of Dionysius who was from Ionia, which is in modern-day Turkey. Dionysius set up a pirate base on the island of Sicily that allowed him and his fellow pirates to plunder ships that happened to sail past.

    Pirates of the Caribbean

    While Dionysius may have been the first recorded pirate, the most famous pirates lived during the 17th and 18th centuries, which came to be known as the golden age of sea piracy.

    This was the heyday of pirates such as Blackbeard, also known as Edward Teach; William Kidd; Henry Morgan; Calico Jack; and Anne Bonny. They plundered Spanish treasure ships in the Caribbean, known as the Spanish Main, that were carrying silver from the mines in Bolivia back to the king of Spain.

    Islands such as Jamaica, Tortuga and the Bahamas, as well the North Carolina coast, all became notable pirate havens. Port Royal, on the island of Jamaica, in particular, was a notorious pirate refuge. It was ideally positioned for preying upon Spanish galleons sailing across the Atlantic from ports in Panama and Venezuela. Johnny Depp’s character, Jack Sparrow, swashbuckled around a fictionalized Port Royal in the first “Pirates of the Caribbean” film.

    21st-century pirates

    The 2013 Hollywood movie “Captain Phillips,” starring Tom Hanks, drew attention back to real-world pirates and piracy. The movie was based on a real-life 2009 attack by Somali pirates on a ship named the MV Maersk Alabama, which was carrying food to Kenya. The 500-foot-long vessel and its crew were rescued by the U.S. Navy.

    To better understand 21st-century piracy, my research team compiled data on all pirate attacks from 1995 to the present day. We found three main piracy hot spots: the Gulf of Aden near Somalia, the Strait of Malacca in Southeast Asia and the Gulf of Guinea off the coast of West Africa. All three locations experience the conditions that attract pirates: ship traffic, valuable cargo and weak governments.

    Why become a pirate?

    People become pirates for many reasons, not the least of which is to escape poverty and enslavement. Others just want adventure and to travel the world. These are the same motivations that drove commerce raiding in the ancient world, during the golden age of piracy, and even today.

    While we may never know the first pirate, just like we will never know the very first thief, historical evidence shows that sea-raiding has been around since the very first boats traversed the world’s waterways. Despite efforts to end piracy, my research shows that the conditions that produce ship looting remain and will likely always exist.

  • 2026 FIFA World Cup expansion will have a big climate footprint, with matches from Mexico to Canada – here’s what fans can do

    When the FIFA World Cup hits North America in June 2026, 48 teams and millions of sports fans will be traveling among venues spread across Canada, the United States and Mexico.

    It’s a dramatic expansion – 16 more teams will be playing than in recent years, with a jump from 64 to 104 matches. The tournament, whether you call it soccer or football, is projected to bring in over US$10 billion in revenue. But the expansion will also mean a lot more travel and other activities that contribute to climate change.

    The environmental impacts of giant sporting events like the World Cup create a complex paradox for an industry grappling with its future in a warming world.

    A sustainability conundrum

    Sports are undeniably experiencing the effects of climate change. Rising global temperatures are putting athletes’ health at risk during summer heat waves and shortening winter sports seasons. Many of the 2026 World Cup venues often see heat waves in June and early July, when the tournament is scheduled.

    There is a divide over how sports should respond.

    Some athletes are speaking out for more sustainable choices and have called on lawmakers to take steps to limit climate-warming emissions. At the same time, the sport industry is growing and facing a constant push to increase revenue. The NCAA is also considering expanding its March Madness basketball tournaments from 68 teams currently to as many as 76.

    Estimates for the 2026 World Cup show what large tournament expansions can mean for the climate. A report from Scientists for Global Responsibility estimates that the expanded World Cup could generate over 9 million metric tons of carbon dioxide equivalent, nearly double the average of the past four World Cups.

    This massive increase – and the increase that would come if the NCAA basketball tournaments also expand – would primarily be driven by air travel as fans and players fly among event cities that are thousands of miles apart.

    A lot of money is at stake, but so is the climate

    Sports are big business, and adding more matches to events like the World Cup and NCAA tournaments will likely lead to larger media rights contracts and greater gate receipts from more fans attending the events, boosting revenues. These are powerful financial incentives.

    In the NCAA’s case, there is another reason to consider a larger tournament: The House v. NCAA settlement opened the door for college athletic departments to share revenue with athletes, which will significantly increase costs for many college programs. More teams would mean more television revenue and, crucially, more revenue to be distributed to member NCAA institutions and their athletic conferences.

    When climate promises become greenwashing

    The inherent conflict between maximizing profit through growth and minimizing environmental footprint presents a dilemma for sports.

    Several sport organizations have promised to reduce their impact on the climate, including signing up for initiatives like the United Nations Sports for Climate Action Framework.

    However, as sports tournaments and exhibition games expand, it can become increasingly hard for sports organizations to meet their climate commitments. In some cases, groups making sustainability commitments have been accused of greenwashing, suggesting the goals are more about public relations than making genuine, measurable changes.

    For example, FIFA’s early claims that it would hold a “fully carbon-neutral” World Cup in Qatar in 2022 were challenged by a group of European countries that accused soccer’s world governing body of underestimating emissions. The Swiss Fairness Commission, which monitors fairness in advertising, considered the complaints and determined that FIFA’s claims could not be substantiated.

    Aviation is often the biggest driver of emissions. A study that colleagues and I conducted on the NCAA men’s basketball tournament found about 80% of its emissions were connected to travel. And that was after the NCAA began using the pod system, which is designed to keep teams closer to home for the first and second rounds.

    Finding practical solutions

    Some academics, observing the rising emissions trend, have called for radical solutions like the end of commercialized sports or drastically limiting who can attend sporting events, with a focus on fans from the region.

    These solutions are frankly not practical, in my view, nor do they align with other positive developments. The growing popularity of women’s sports shows the challenge in limiting sports events – more games expands participation but adds to the industry’s overall footprint.

    Further compounding the challenges of reducing environmental impact is the amount of fan travel, which is outside the direct control of the sports organization or event organizers.

    Many fans will follow their teams long distances, especially for mega-events like the World Cup or the NCAA tournament. During the men’s World Cup in Russia in 2018, more than 840,000 fans traveled from other countries. The top countries by number of fans, after Russia, were China, the U.S., Mexico and Argentina.

    There is an argument that distributed sporting events like March Madness or the World Cup can be better in some ways for local environments because they don’t overwhelm a single city. However, merely spreading the impact does not necessarily reduce it, particularly when considering the effects on climate change.

    How fans can cut their environmental footprint

    Sport organizations and event planners can take steps to be more sustainable and also encourage more sustainable choices among fans. Fans can reduce their environmental impact in a variety of ways. For example:

    • Avoid taking airplanes for shorter distances, such as between FIFA venues in Philadelphia, New York and Boston, and carpool or take Amtrak instead. Planes can be more efficient for long distances, but air travel is still a major contributing factor to emissions.

    • While in a host city, use mass transit or rent electric vehicles or bicycles for local travel.

    • Consider sustainable accommodations, such as short-term rentals that might have a smaller environmental footprint than a hotel. Or stay at a certified green hotel that makes an effort to be more efficient in its use of water and energy.

    • Engage in sustainable pregame and postgame activities, such as choosing local, sustainable food options, and minimize waste.

    • You can also pay to offset carbon emissions for attending different sporting events, much like concertgoers do when they attend musical festivals. While critics question offsets’ true environmental benefit, they do represent people’s growing awareness of their environmental footprint.

    Through all these options, it’s clear that sports face a significant challenge in addressing their environmental impacts and encouraging fans to be more sustainable, while simultaneously trying to meet ambitious business and environmental targets.

    In my view, a sustainable path forward will require strategic, yet genuine, commitment by the sports industry and its fans, and a willingness to prioritize long-term planetary health alongside economic gains – balancing the sport and sustainability.

  • Most Pennsylvania voters ignore judicial elections − a political scientist explains why they matter, especially in a battleground state

    This November, there will be no candidate for president, governor, senator or even representative on the Pennsylvania ballot.

    Pennsylvanians will vote, however, on three members of their seven-member state Supreme Court.

    These are retention elections, which means that voters will decide whether to keep the current members of the court or remove them.

    The three seats up for grabs are three of the five Democrats that hold the majority on the court. They are Justices Christine Donohue, Kevin Dougherty and David Wecht.

    While the typical voter may not think much about judicial elections, political operatives and political scientists, like me, know they have consequences.

    I think it’s important that voters understand what a retention election is and why state judicial elections are growing in political importance in the U.S.

    Retention elections

    Federal judges are appointed by the U.S. president, confirmed by the U.S. Senate, and can serve for the rest of their lives. State judges, however, are put in place in a variety of ways.

    The most powerful state courts are the so-called “courts of last resort.” These are essentially the supreme courts of each state. The method for selecting judges in these courts has varied over time and across the states. Currently, states use either gubernatorial appointment, legislative appointment, partisan elections, nonpartisan elections, or a merit process for selecting the judges of their highest courts.

    Pennsylvania has partisan elections, meaning judges run for office attached to political parties, just like a candidate would run for governor or president. However, it is only in their first race for office that a judge runs in a competitive partisan election. After they assume the bench, they participate in retention elections every 10 years. These retention elections are considered nonpartisan, since party labels do not appear on the ballot.

    Essentially, a retention election is an up or down vote. If more than 50% of voters cast a vote in opposition to a sitting judge, that judge will be out of the office at the end of their term. The governor, who is currently Democrat Josh Shapiro, then makes a temporary appointment to fill the seat with a special election held in the next odd year – in this case, 2027. But any appointments would need to be confirmed by the Republican-controlled state Senate, which may not confirm his picks.

    Politicization of the state courts

    Judges win retention elections over 90% of the time. So why should people bother to cast their vote?

    Courts, including state courts, have become highly politicized over the past several decades. A marked increase in politicization occurred for the U.S. Supreme Court after the failed nomination of Robert Bork in the 1980s.

    This politicization has since trickled down to lower federal courts and the states.

    State supreme courts have always made big decisions, but the nationalization of American politics – where national partisan politics drive voter behavior in local elections – has elevated the controversy over state supreme court decisions on issues such as reproductive rights, trans rights, COVID-19 restrictions, environmental protection and more.

    This issue became more acute when courts in battleground states were thrust to the center of adjudicating false claims of election fraud during the 2020 U.S. presidential election. And judges have faced increasing threats, particularly when opposing actions of the Trump administration, as President Donald Trump is prone to calling out specific judges in decisions that he does not like.

    The Pennsylvania Supreme Court has received additional attention, in part due to the outsized role it has played in recent redistricting. In 2018, the court threw out the congressional districts drawn by the General Assembly in 2011 and invited a new plan from the governor and General Assembly. The two came to a political loggerhead, so the Supreme Court ended up using its own map as a replacement.

    In 2022, the state Supreme Court once again took control of redistricting after Pennyslvania’s then-Gov. Tom Wolf vetoed the congressional district map approved by the General Assembly.

    Given the importance of state supreme courts, particularly in federal elections cases in battleground states like Pennsylvania, it is little wonder why their elections are gaining attention.

    The April 2025 Wisconsin Supreme Court race was the most expensive state judicial race in U.S. history, with $100 million in spending, including significant contributions from billionaires Elon Musk and George Soros.

    That was one seat.

    Pennsylvania has three up for grabs in November 2025, with the potential to swing the current Democratic majority.

    And retention elections are politically simple for opponents. As one Republican political consultant told investigative news outlet Spotlight PA: “This is a political consultant’s dream, because your message is just one thing, and that’s ‘No.’”

    This can give some advantage to Republicans in a state that Trump won in 2024 and in a low-turnout election. The question will be whether there is more energy motivating opponents to turn out against the Democratic majority or supporters seeking to maintain the status quo.

    The stakes for Pennsylvania in 2025

    Much is at stake for Pennsylvanians in the fall. Republicans see this as their best opportunity to break the firm 5-2 Democratic majority on the court. This would pave the way for very different judicial decisions. Many of the court’s recent election-related rulings were made on narrow 4-3 votes that could swing differently if the composition of the court changes.

    Republicans have had their power in Harrisburg diminished with Shapiro in the governor’s mansion and a one-seat Democratic majority in the state House of Representatives over the past two terms.

    A Republican majority on the court would significantly change the balance of power in Harrisburg.

    But it is important to focus not only on the top court. The state’s two appellate-level courts – one step below the state Supreme Court – also have two important races and two retention votes in November that will decide the judiciary’s relationship with the governor and General Assembly.

  • Cleaner air in east Asia has driven recent acceleration in global warming – new study

    Source: ForeignAffairs4

    Source: The Conversation – UK – By Laura Wilcox, Professor, National Centre for Atmospheric Science, University of Reading

    Global warming has picked up pace since around 2010, leading to the recent string of record warm years. Why this is happening is still unclear, and among the biggest questions in climate science today. Our new study reveals that reductions in air pollution – particularly in China and east Asia – are a key reason for this faster warming.

    Cleanup of sulphur emissions from global shipping has been implicated in past research. But that cleanup only began in 2020, so it’s considered too weak to explain the full extent of this acceleration. Nasa researchers have suggested that changes in clouds could play a role, either through reductions in cloud cover in the tropics or over the North Pacific.

    One factor that has not been well quantified, however, is the effect of monumental efforts by countries in east Asia, notably China, to combat air pollution and improve public health through strict air quality policies. There has already been a 75% reduction in east Asian sulphur dioxide emissions since around 2013, and that cleanup effort picked up pace just as global warming began accelerating.

    Our study addresses the link between east Asian air quality improvements and global temperature, building on the efforts of eight teams of climate modellers across the world.

    We have found that polluted air may have been masking the full effects of global warming. Cleaner air could now be revealing more of the human-induced global warming from greenhouse gases.

    In addition to causing millions of premature deaths, air pollution shields the Earth from sunlight and therefore cools the surface. There has been so much air pollution that it has held human-induced warming in check by up to 0.5°C over the last century.

    With the cleanup of air pollution, something that’s vital for human health, this artificial sunshade is removed. Since greenhouse gas emissions have kept on increasing, the result is that the Earth’s surface is warming faster than ever before.

    Modelling the cleanup

    Our team used 160 computer simulations from eight global climate models. This enabled us to better quantify the effects that east Asian air pollution has on global temperature and rainfall patterns. We simulated a cleanup of pollution similar to what has happened in the real world since 2010. We found an extra global warming of around 0.07°C.

    While this is a small number compared with the full global warming of around 1.3°C since 1850, it is still enough to explain the recent acceleration in global warming when we take away year-to-year swings in temperature from natural cycles such as El Niño, a climate phenomenon in the Pacific that affects weather patterns globally.

    Based on long-term trends, we would have expected around 0.23°C of warming since 2010. However, we actually measured around 0.33°C. While the additional 0.1°C can largely be explained by the east Asian air pollution cleanup, other factors include the change in shipping emissions and the recent accelerated increase in methane concentrations in the atmosphere.

    Air pollution causes cooling by reflecting sunlight or by changing the properties of clouds so they reflect more sunlight. The cleanup in east Asian air pollution influences global temperatures because it reduces the shading effect of the pollution over east Asia itself. It also means less pollution is blown across the north Pacific, causing clouds in the east Pacific to reflect less sunlight.

    The pattern of these changes across the North Pacific simulated in our models matches that seen in satellite observations. Our models and temperature observations also show relatively strong warming over the North Pacific, downwind from east Asia.

    The main source of global warming is still greenhouse gas emissions, and a cleanup of air pollution was both necessary and overdue. This did not cause the additional warming but rather, removed an artificial cooling that has for a time helped shield us from some of the extreme weather and other well-established consequences of climate change.

    Global warming will continue for decades. Indeed, our past and future emissions of greenhouse gases will affect the climate for centuries. However, air pollution is quickly removed from the atmosphere, and the recent acceleration in global warming from this particular unmasking may therefore be short-lived.

  • Was the Air India crash caused by pilot error or technical fault? None of the theories holds up – yet

    Source: ForeignAffairs4

    Source: The Conversation – Global Perspectives – By Guido Carim Junior, Senior Lecturer in Aviation, Griffith University

    Over the weekend, the Indian Aircraft Accident Investigation Bureau released a preliminary report on last month’s crash of Air India flight 171, which killed 260 people, 19 of them on the ground.

    The aim of a preliminary report is to present factual information gathered so far and to inform further lines of inquiry. However, the 15-page document has also led to unfounded speculation and theories that are currently not supported by the evidence.

    Here’s what the report actually says, why we don’t yet know what caused the crash, and why it’s important not to speculate.

    What the preliminary report does say

    What we know for certain is that the aircraft lost power in both engines just after takeoff.

    According to the report, this is supported by video footage showing the deployment of the ram air turbine (RAT), and the examination of the air inlet door of the auxiliary power unit (APU).

    The RAT is deployed when both engines fail, all hydraulic systems are lost, or there is a total electrical power loss. The APU air inlet door opens when the system attempts to start automatically due to dual engine failure.

    The preliminary investigation suggests both engines shut down because the fuel flow stopped. Attention has now shifted to the fuel control switches, located on the throttle lever panel between the pilots.

    This is what the fuel switches look like, with the throttle lever above them.
    Aircraft Accident Investigation Bureau

    Data from the enhanced airborne flight recorder suggests these switches may have been moved from “run” to “cutoff” three seconds after liftoff. Ten seconds later, the switches were moved back to “run”.

    The report also suggests the pilots were aware the engines had shut down and attempted to restart them. Despite their effort, the engines couldn’t restart in time.

    We don’t know what the pilots did

    Flight data recorders don’t capture pilot actions. They record system responses and sensor data, which can sometimes lead to the belief they’re an accurate representation of the pilot’s actions in the cockpit.

    While this is true most of the time, this is not always the case.

    In my own work investigating safety incidents, I’ve seen cases in which automated systems misinterpreted inputs. In one case, a system recorded a pilot pressing the same button six times in two seconds, something humanly impossible. On further investigation, it turned out to be a faulty system, not a real action.

    We cannot yet rule out the possibility that system damage or sensor error led to false data being recorded. We also don’t know whether the pilots unintentionally flicked the switches to “cutoff”. And we may never know.

    As we also don’t have a camera in the cockpit, any interpretation of pilots’ actions will be made indirectly, usually through the data sensed by the aircraft and the conversation, sound and noise captured by the environmental microphone available in the cockpit.

    We don’t have the full conversation between the pilots

    Perhaps the most confusing clue in the report was an excerpt of a conversation between the pilots. It says:

    In the cockpit voice recording, one of the pilots is heard asking the other why did he cutoff. The other pilot responded that he did not do so.

    This short exchange is entirely without context. First, we don’t know who says what. Second, we don’t know when the question was asked – after takeoff, or after the engine started to lose power? Third, we don’t know the exact words used, because the excerpt in the report is paraphrased.

    Finally, we don’t know whether the exchange referred to the engine status or the switch position. Again, we may never know.

    What’s crucial here is that the current available evidence doesn’t support any theory about intentional fuel cutoff by either of the pilots. To say otherwise is unfounded speculation.

    We don’t know if there was a mechanical failure

    The preliminary report indicates that, for now, there are no actions required by Boeing, General Electric or any company that operates the Boeing 787-8 and/or GEnx-1B engine.

    This has led some to speculate that a mechanical failure has been ruled out. Again, it is far too early to conclude that.

    What the preliminary report shows is that the investigation team has not found any evidence to suggest the aircraft suffered a catastrophic failure that requires immediate attention or suspension of operations around the world.

    This could be because there was no catastrophic failure. It could also be because the physical evidence has been so badly damaged that investigators will need more time and other sources of evidence to learn what happened.

    Why we must resist premature conclusions

    In the aftermath of an accident, there is much at stake for many people: the manufacturer of the aircraft, the airline, the airport, civil aviation authority and others. The families of the victims understandably demand answers.

    It’s also tempting to latch onto a convenient explanation. But the preliminary report is not the full story. It’s based on very limited data, analysed under immense pressure, and without access to every subsystem or mechanical trace.

    The final report is still to come. Until then, the responsible position for regulators, experts and the public is to withhold judgement.

    This tragedy reminds us that aviation safety depends on patient and thorough investigation – not media soundbites or unqualified expert commentary. We owe it to the victims and their families to get the facts right, not just fast.

  • How do you stop an AI model turning Nazi? What the Grok drama reveals about AI training

    Grok, the artificial intelligence (AI) chatbot embedded in X (formerly Twitter) and built by Elon Musk’s company xAI, is back in the headlines after calling itself “MechaHitler” and producing pro-Nazi remarks.

    The developers have apologised for the “inappropriate posts” and “taken action to ban hate speech” from Grok’s posts on X. Debates about AI bias have been revived too.

    But the latest Grok controversy is revealing not for the extremist outputs, but for how it exposes a fundamental dishonesty in AI development. Musk claims to be building a “truth-seeking” AI free from bias, yet the technical implementation reveals systemic ideological programming.

    This amounts to an accidental case study in how AI systems embed their creators’ values, with Musk’s unfiltered public presence making visible what other companies typically obscure.

    What is Grok?

    Grok is an AI chatbot with “a twist of humor and a dash of rebellion” developed by xAI, which also owns the X social media platform.

    The first version of Grok launched in 2023. Independent evaluations suggest the latest model, Grok 4, outpaces competitors on “intelligence” tests. The chatbot is available standalone and on X.

    xAI states “AI’s knowledge should be all-encompassing and as far-reaching as possible”. Musk has previously positioned Grok as a truth-telling alternative to chatbots accused of being “woke” by right-wing commentators.

    But beyond the latest Nazism scandal, Grok has made headlines for generating threats of sexual violence, bringing up “white genocide” in South Africa, and making insulting statements about politicians. The latter led to its ban in Turkey.

    So how do developers imbue an AI with such values and shape chatbot behaviour? Today’s chatbots are built using large language models (LLMs), which offer several levers developers can lean on.

    What makes an AI ‘behave’ this way?

    Pre-training

    First, developers curate the data used during pre-training – the first step in building a chatbot. This involves not just filtering unwanted content, but also emphasising desired material.

    GPT-3 was shown Wikipedia up to six times more than other datasets as OpenAI considered it higher quality. Grok is trained on various sources, including posts from X, which might explain why Grok has been reported to check Elon Musk’s opinion on controversial topics.

    Musk has shared that xAI curates Grok’s training data, for example to improve legal knowledge and to remove LLM-generated content for quality control. He also appealed to the X community for difficult “galaxy brain” problems and facts that are “politically incorrect, but nonetheless factually true”.

    We don’t know if these data were used, or what quality-control measures were applied.

    Fine-tuning

    The second step, fine-tuning, adjusts LLM behaviour using feedback. Developers create detailed manuals outlining their preferred ethical stances, which either human reviewers or AI systems then use as a rubric to evaluate and improve the chatbot’s responses, effectively coding these values into the machine.

    A Business Insider investigation revealed xAI’s instructions to human
    “AI tutors” instructed them to look for “woke ideology” and “cancel culture”. While the onboarding documents said Grok shouldn’t “impose an opinion that confirms or denies a user’s bias”, they also stated it should avoid responses that claim both sides of a debate have merit when they do not.

    System prompts

    The system prompt – instructions provided before every conversation – guides behaviour once the model is deployed.

    To its credit, xAI publishes Grok’s system prompts. Its instructions to “assume subjective viewpoints sourced from the media are biased” and “not shy away from making claims which are politically incorrect, as long as they are well substantiated” were likely key factors in the latest controversy.

    These prompts are being updated daily at the time of writing, and their evolution is a fascinating case study in itself.

    Guardrails

    Finally, developers can also add guardrails – filters that block certain requests or responses. OpenAI claims it doesn’t permit ChatGPT “to generate hateful, harassing, violent or adult content”. Meanwhile, the Chinese model DeepSeek censors discussion of Tianamen Square.

    Ad-hoc testing when writing this article suggests Grok is much less restrained in this regard than competitor products.

    The transparency paradox

    Grok’s Nazi controversy highlights a deeper ethical issue: would we prefer AI companies to be explicitly ideological and honest about it, or maintain the fiction of neutrality while secretly embedding their values?

    Every major AI system reflects its creator’s worldview – from Microsoft Copilot’s risk-averse corporate perspective to Anthropic Claude’s safety-focused ethos. The difference is transparency.

    Musk’s public statements make it easy to trace Grok’s behaviours back to Musk’s stated beliefs about “woke ideology” and media bias. Meanwhile, when other platforms misfire spectacularly, we’re left guessing whether this reflects leadership views, corporate risk aversion, regulatory pressure, or accident.

    This feels familiar. Grok resembles Microsoft’s 2016 hate-speech-spouting Tay chatbot, also trained on Twitter data and set loose on Twitter before being shut down.

    But there’s a crucial difference. Tay’s racism emerged from user manipulation and poor safeguards – an unintended consequence. Grok’s behaviour appears to stem at least partially from its design.

    The real lesson from Grok is about honesty in AI development. As these systems become more powerful and widespread (Grok support in Tesla vehicles was just announced), the question isn’t whether AI will reflect human values. It’s whether companies will be transparent about whose values they’re encoding and why.

    Musk’s approach is simultaneously more honest (we can see his influence) and more deceptive (claiming objectivity while programming subjectivity) than his competitors.

    In an industry built on the myth of neutral algorithms, Grok reveals what’s been true all along: there’s no such thing as unbiased AI – only AI whose biases we can see with varying degrees of clarity.

  • Even a day off alcohol makes a difference – our timeline maps the health benefits when you stop drinking

    Alcohol has many negative effects on our health, some of which may surprise you. These include short-term impacts such as waking up with a pounding head or anxiety, to long-term effects including cancer.

    If you are thinking about taking some time off alcohol, you’ll find many quick wins and long-term gains for your health.

    How long will you have to wait to feel the benefits?

    We’ve made a timeline – based on scientific research – that shows what you might feel in the first days, weeks, months and years after taking a break from alcohol.

    Some benefits start immediately, so every day without alcohol is a win for your health.

    After one day

    Alcohol takes around 24 hours to completely leave your body, so you may start noticing improvements after just one day.

    Alcohol makes you need to urinate more often, causing dehydration. But your body can absorb a glass of water almost immediately, so once alcohol is out of your system alcohol dehydration is reduced, improving digestion, brain function and energy levels.

    Alcohol also reduces the liver’s ability to regulate blood sugar. Once alcohol leaves the system, blood sugar begins to normalise.

    If you are a daily drinker you may feel a bit worse to start with while your body adjusts to not having alcohol in its system all the time. You may initially notice disrupted sleep, mood changes, sweating or tremors. Most symptoms usually resolve in about a week without alcohol.

    After one week

    Even though alcohol can make you feel sleepy at first, it disrupts your sleep cycle. By the end of an alcohol-free week, you may notice you are more energetic in the mornings as a result of getting better quality sleep.

    As the body’s filter, the liver does much of the heavy lifting in processing alcohol and can be easily damaged even with moderate drinking.

    The liver is important for cleaning blood, processing nutrients and producing bile that helps with digestion.

    But it can also regenerate quickly. If you have only mild damage in the liver, seven days may be enough to reduce liver fat and heal mild scarring and tissue damage.

    Even small amounts of alcohol can impair brain functioning. So quitting can help improve brain health within a few days in light to moderate drinkers and within a month even for very heavy dependent drinkers.

    Alcohol damages your liver, but it’s very good at regenerating and healing itself.

    After one month

    Alcohol can make managing mood harder and worsen symptoms of anxiety and depression. After a few weeks, most people start to feel better. Even very heavy drinkers report better mood after one to two months.

    As your sleep and mood improve you may also notice more energy and greater wellbeing.

    After a month of abstinence regular drinkers also report feeling more confident about making changes to how they drink.

    You may lose weight and body fat. Alcohol contains a lot of kilojules and can trigger hunger reward systems, making us overeat or choose less healthy foods when drinking.

    Even your skin will thank you. Alcohol can make you look older through dehydration and inflammation, which can be reversed when you quit.

    Alcohol irritates the gut and disrupts normal stomach functioning, causing bloating, indigestion, heartburn and diarrhoea. These symptoms usually start to resolve within four weeks.

    One month of abstinence, insulin resistance – which can lead to high blood sugar – significantly reduces by 25%. Blood pressure also reduces (by 6%) and cancer-related growth factors declines, lowering your risk of cancer.

    After six months

    The liver starts to repair within weeks. For moderate drinkers, damage to your liver could be fully reversed by six months.

    At this point, even heavy drinkers may notice they’re better at fighting infections and feel healthier overall.

    After one year or more

    Alcohol contributes to or causes a large number of chronic diseases, including heart disease, stroke, type 2 diabetes, and seven different types of cancer, as well as mental health issues. All of these risks can be reduced by quitting or cutting back on alcohol.

    Alcohol increases blood pressure. High blood pressure (hypertension) is the top risk factor for death in the world. A small 2mmHg increase in blood pressure above the normal range (120mmHG) increases death from stroke by 10% and from coronary artery disease by 7%.

    Cutting back on alcohol to less than two drinks a day can reduce blood pressure significantly, reducing risk of stroke and heart disease. Reducing blood pressure also reduces risk of kidney disease, eye problems and even erectile dysfunction.

    With sustained abstinence, your risk of getting any type of cancer drops. One study looked at cancer risk for more than 4 million adults over three to seven years and found the risk of alcohol-related cancer dropped by 4%, even for light drinkers who quit. Reducing from heavy to moderate drinking reduced alcohol-related cancer risk by 9%.

    Making a change

    Any reduction in drinking will have some noticeable and immediate benefits to your brain and general health. The less you drink and the longer you go between drinks, the healthier you will be.

    Whether you aim to cut back or quit entirely, there are some simple things you can do to help you stick with it:

    If you are still wondering about whether to make changes or not you can check your drinking risk here.

    If you have tried to cut back and found it difficult you may need professional help. Call the National Alcohol and other Drug Hotline on 1800 250 015 and they will put you in touch with services in your area that can help. You can also talk to your GP.

  • Cycling can be 4 times more efficient than walking. A biomechanics expert explains why

    Source: ForeignAffairs4

    Source: The Conversation – Global Perspectives – By Anthony Blazevich, Professor of Biomechanics, Edith Cowan University

    You’re standing at your front door, facing a five kilometre commute to work. But you don’t have your car, and there’s no bus route. You can walk for an hour – or jump on your bicycle and arrive in 15 minutes, barely breaking a sweat. You choose the latter.

    Many people would make the same choice. It’s estimated that there are more than a billion bikes in the world. Cycling represents one of the most energy-efficient forms of transport ever invented, allowing humans to travel faster and farther while using less energy than walking or running.

    But why exactly does pedalling feel so much easier than pounding the pavement? The answer lies in the elegant biomechanics of how our bodies interact with this two-wheeled machine.

    A wonderfully simple machine

    At its heart, a bicycle is wonderfully simple: two wheels (hence “bi-cycle”), pedals that transfer power through a chain to the rear wheel, and gears that let us fine-tune our effort. But this simplicity masks an engineering that perfectly complements human physiology.

    When we walk or run, we essentially fall forward in a controlled manner, catching ourselves with each step. Our legs must swing through large arcs, lifting our heavy limbs against gravity with every stride. This swinging motion alone consumes a lot of energy. Imagine: how tiring would it be to even swing your arms continuously for an hour?

    On a bicycle, your legs move through a much smaller, circular motion. Instead of swinging your entire leg weight with each step, you’re simply rotating your thighs and calves through a compact pedalling cycle. The energy savings are immediately noticeable.

    But the real efficiency gains come from how bicycles transfer human power to forward motion. When you walk or run, each footstep involves a mini-collision with the ground. You can hear it as the slap of your shoe against the road, and you can feel it as vibrations running through your body. This is energy being lost, literally dissipated as sound and heat after being sent through your muscles and joints.

    Walking and running also involve another source of inefficiency: with each step, you actually brake yourself slightly before propelling forward. As your foot lands ahead of your body, it creates a backwards force that momentarily slows you down. Your muscles then have to work extra hard to overcome this self-imposed braking and accelerate you forward again.

    Kissing the road

    Bicycles use one of the world’s great inventions to solve these problems – wheels.

    Instead of a collision, you get rolling contact – each part of the tyre gently “kisses” the road surface before lifting off. No energy is lost to impact. And because the wheel rotates smoothly so the force acts perfectly vertically on the ground, there’s no stop-start braking action. The force from your pedalling translates directly into forward motion.

    But bicycles also help our muscles to work at their best. Human muscles have a fundamental limitation: the faster they contract, the weaker they become and the more energy they consume.

    This is the famous force-velocity relationship of muscles. And it’s why sprinting feels so much harder than jogging or walking – your muscles are working near their speed limit, becoming less efficient with every stride.

    Bicycle gears solve this problem for us. As you go faster, you can shift to a higher gear so your muscles don’t have to work faster while the bike accelerates. Your muscles can stay in their sweet spot for both force production and energy cost. It’s like having a personal assistant that continuously adjusts your workload to keep you in the peak performance zone.

    Cycling can be at least four times more energy-efficient than walking and eight times more efficient than running.

    Walking sometimes wins out

    But bicycles aren’t always superior.

    On very steep hills of more than about 15% gradient (so you rise 1.5 metres every 10 metres of distance), your legs struggle to generate enough force through the circular pedalling motion to lift you and the bike up the hill. We can produce more force by pushing our legs straight out, so walking (or climbing) becomes more effective.

    Even if roads were built, we wouldn’t pedal up Mount Everest.

    This isn’t the case for downhills. While cycling downhill becomes progressively easier (eventually requiring no energy at all), walking down steep slopes actually becomes harder.

    Once the gradient exceeds about 10% (it drops by one metre for every ten metres of distance), each downhill step creates jarring impacts that waste energy and stress your joints. Walking and running downhill isn’t always as easy as we’d expect.

    Not just a transportation device

    The numbers speak for themselves. Cycling can be at least four times more energy-efficient than walking and eight times more efficient than running. This efficiency comes from minimising three major energy drains: limb movement, ground impact and muscle speed limitations.

    So next time you effortlessly cruise past pedestrians on your morning bike commute, take a moment to appreciate the biomechanical work of art beneath you. Your bicycle isn’t just a transport device, but a perfectly evolved machine that works in partnership with your physiology, turning your raw muscle power into efficient motion.

  • Can’t work out without music? Neither could the ancient Greeks and Romans

    Source: ForeignAffairs4

    These days when you see people exercising, they’re usually also listening to music, whether they’re at the gym, or out jogging on the street.

    It makes sense, as studies have shown listening to music can help you get the most out of a workout.

    Somehow the ancient Greeks and Romans knew this too, long before modern science was there to back it.

    A more than 2,000-year-old habit

    In his oration To the People of Alexandria, the Greek writer Dio Chrysostom (40-110 CE) complained about a phenomenon he saw all the time.

    Dio wrote people loved to listen to music in their daily activities. According to him, music could be found in the courtroom, in the lecture theatre, in the doctor’s room, and even in the gym.

    “Everything is done to music […] people will presently go so far as to use song to accompany their exercise in the gymnasium,” Dio wrote.

    But exercising to music wasn’t a new thing in his day. This practice has been recorded across the ancient Greek and Roman worlds from the earliest times, and as far back as the poems of Homer (circa 800 BCE).

    Why exercise to music?

    There are many depictions of professional athletes training, or competing, to the accompaniment of music in ancient Greek vase paintings.

    In one vase painting from the 5th century BCE, a group of athletes trains while a musician plays the aulos, a type of ancient pipe instrument.

    The ancient writer Plutarch of Chaeronea (46-119 CE) tells us music was also played while people wrestled or did athletics.

    Athenian writer Flavius Philostratus (circa 170-245 CE) offers clues as to why. In a book about gymnastics, Philostratus wrote music served to stimulate athletes, and that their performance might be improved through listening to music.

    Today’s researchers have proven this to be true. One 2020 study involving 3,599 participants showed listening to music during exercise had many benefits, such as reducing the perception of fatigue and exertion, and improving physical performance and breathing.

    Singing and trumpets

    Since ancient people didn’t have electronic devices, they found other ways to exercise to music. Some had music played by a musician during their exercise routine. Others sang while they exercised.

    Singing while playing ball games was particularly popular. In Homer’s Odyssey (circa 8th century BCE), Nausicaa, the daughter of the King of Phaeacia, plays a ball game with her girl friends, and they all sing songs as they play.

    Similarly, the historian Carystius of Pergamum (2nd century BCE) wrote the women of his time “sang as they played ball”.

    Another popular activity was dancing to music. Dancing was widely regarded as a gymnastic exercise people could do for better health.

    One famous advocate of the benefits of dancing as exercise was the great Athenian philosopher Socrates (circa 470-399 BCE). According to the historian Diogenes Laertius (3rd century CE), “it was Socrates’ regular habit to dance, thinking that such exercise helped to keep the body in good condition”.

    Exercising to music was depicted in several ancient Greek vase painting.

    Apart from individuals using music in their personal exercise, soldiers also did training exercises, and marched to battle, to the sound of trumpets.

    Don’t skip leg day

    There was a belief in ancient Greek and Roman that music and exercise played an important role in shaping and developing the body and soul.

    The ideal was harmony and moderation. The body and soul needed to be balanced and proportionate in all their parts, without any excess. As such, doing one kind of exercise too often, or exercising one body part excessively, was frowned upon.

    The physician Galen of Pergamum (129-216 CE) criticised types of exercise that focused too much on one part of the body. He preferred ball games as they exercised the whole body evenly.

    Immoderation in music – that is, listening to too much, or listening to music that was too emotional – was also sometimes frowned upon.

    For example, the Athenian philosopher Plato (circa 428-348 BCE) famously argued most music should be censored as it can stir the passions too strongly. Plato thought only simple and unemotional music, listened to in moderation, should be allowed.

    If the ancients could see today’s people running along the pavement with music thumping in their ears, they would surely be amazed. And they’d probably approve – as long as it wasn’t being done in excess.

  • Why Texas Hill Country, where a devastating flood killed more than 130 people, is one of the deadliest places in the US for flash flooding

    Source: ForeignAffairs4

    Texas Hill Country is known for its landscapes, where shallow rivers wind among hills and through rugged valleys. That geography also makes it one of the deadliest places in the U.S. for flash flooding.

    In the early hours of July 4, 2025, a flash flood swept through an area of Hill Country dotted with summer camps and small towns about 70 miles northwest of San Antonio. More than 130 people died in the flooding. The majority of them were in Kerr County, including more than two dozen girls and counselors at one summer camp, Camp Mystic. Dozens more people were still unaccounted for a week later.

    The flooding began with a heavy downpour, with more than 10 inches of rain in some areas, that sent water sheeting off the hillsides and into creeks. The creeks poured into the Guadalupe River.

    A river gauge at Hunt, Texas, near Camp Mystic, showed how quickly the river flooded: Around 3 a.m. on July 4, the Guadalupe River was rising about 1 foot every 5 minutes at the gauge, National Weather Service data shows. By 4:30 a.m., it had risen more than 20 feet. As the water moved downstream, it reached Kerrville, where the river rose even faster.

    Flood expert Hatim Sharif, a hydrologist and civil engineer at the University of Texas at San Antonio, explains what makes this part of the country, known as Flash Flood Alley, so dangerous.

    What makes Hill Country so prone to flooding?

    Texas as a whole leads the nation in flood deaths, and by a wide margin. A colleague and I analyzed data from 1959 to 2019 and found 1,069 people had died in flooding in Texas over those six decades. The next highest total was in Louisiana, with 693.

    Many of those flood deaths have been in Hill County. It’s part of an area known as Flash Flood Alley, a crescent of land that curves from near Dallas down to San Antonio and then westward.

    The hills are steep, and the water moves quickly when it floods. This is a semi-arid area with soils that don’t soak up much water, so the water sheets off quickly and the shallow creeks can rise fast.

    When those creeks converge on a river, they can create a surge of water that wipes out homes and washes away cars and, unfortunately, anyone in its path.

    Hill Country has seen some devastating flash floods. In 1987, heavy rain in western Kerr County quickly flooded the Guadalupe River, triggering a flash flood similar to the one in 2025. Ten teenagers being evacuated from a camp died in the rushing water.

    San Antonio, at the eastern edge of Hill Country, was hit with a flash flood on June 12, 2025, that killed 13 people whose cars were swept away by high water from a fast-flooding creek near an interstate ramp in the early morning.

    Why does the region get such strong downpours?

    One reason Hill Country gets powerful downpours is the Balcones Escarpment.

    The escarpment is a line of cliffs and steep hills created by a geologic fault. When warm air from the Gulf rushes up the escarpment, it condenses and can dump a lot of moisture. That water flows down the hills quickly, from many different directions, filling streams and rivers below.

    As temperature rise, the warmer atmosphere can hold more moisture, increasing the downpour and flood risk.

    A tour of the Guadalupe River and its flood risk.

    The same effect can contribute to flash flooding in San Antonio, where the large amount of paved land and lack of updated drainage to control runoff adds to the risk.

    What can be done to improve flash flood safety?

    First, it’s important for people to understand why flash flooding happens and just how fast the water can rise and flow. In many arid areas, dry or shallow creeks can quickly fill up with fast-moving water and become deadly. So people should be aware of the risks and pay attention to the weather.

    Improving flood forecasting, with more detailed models of the physics and water velocity at different locations, can also help.

    Probabilistic forecasting, for example, can provide a range of rainfall scenarios, enabling authorities to prepare for worst-case scenarios. A scientific framework linking rainfall forecasts to the local impacts, such as streamflow, flood depth and water velocity, could also help decision-makers implement timely evacuations or road closures.

    Education is particularly essential for drivers. One to two feet of moving water can wash away a car. People may think their trucks and SUVs can go through anything, but fast-moving water can flip a truck and carry it away.

    Officials can also do more to barricade roads when the flood risk is high to prevent people from driving into harm’s way. We found that 58% of the flood deaths in Texas over the past six decades involved vehicles. The storm on June 12 in San Antonio was an example. It was early morning, and drivers had poor visibility. The cars were hit by fast-rising floodwater from an adjacent creek.

    The devastating losses from the historic flooding in Texas Hill Country on July 4, 2025, are still coming into grim focus, with 121 deaths confirmed and more than 100 still missing as of July 10.

    As emergency responders focus on clearing debris and searching for victims, a less visible and slower disaster has been unfolding: the need for ongoing mental health support long after headlines fade.

    This phase is no less critical than restoring power or rebuilding bridges. Disasters destabilize emotional well-being, leaving distress, prolonged recovery and long-term impacts in their wake long after the event is over.

    Without sustained emotional support, people and communities face heightened risks of prolonged trauma and stalled recovery.

    As an educator and practitioner focused on disability and rehabilitation, I explore the intersection of disaster recovery and the impact of disasters on mental health. Both my research and that of others underscore the vital importance of support systems that not only help people cope in the immediate aftermath of a disaster but also facilitate long-term healing over the months and years that follow – especially for vulnerable populations like children, older adults and people with disabilities.

    The emotional toll of disasters

    Natural disasters disrupt routines, displace families and challenge people’s sense of control and security. In the immediate aftermath, survivors often experience shock, grief, anxiety and sleep disturbances. Often these symptoms may evolve into chronic stress, depression, post-traumatic stress disorder or a combination of these conditions.

    A 2022 study found that Texans who experienced two or more disasters within a five-year span had significantly poorer mental health, as reflected by lower scores on standardized psychological assessments, which highlights the cumulative toll repeated disasters can have on mental well-being.

    After Hurricane Katrina ravaged New Orleans in 2005, nearly a third of survivors continued to experience poor mental health years later.

    And reports following Hurricane Maria in Puerto Rico in 2017 revealed surging rates of anxiety, depression and suicidal thoughts, especially in areas where services remained unavailable for extended periods of time.

    There are actionable ways to make a difference in the recovery process.

    Strained recovery systems

    Disaster response understandably focuses on immediate needs like rescue operations, providing post-disaster housing and repairing damaged infrastructure. In addition, short-term mental health supports such as mobile health clinics are often provided in the immediate aftermath of a disaster.

    However, although emergency services are deployed quickly after a disaster, long-term mental health support is often delayed or under-resourced, leaving many people without continued care during the recovery period, especially in remote or rural communities, exposing deep structural gaps in how recovery systems are designed.

    One year after Hurricane Harvey devastated parts of Texas in 2017, more than 90% of Gulf Coast residents reported ongoing stress related to housing instability, financial hardship or displacement. Yet less than 10% of people stated that they or someone in their household had used mental health services following the disaster.

    Hurricane Helene in 2024 similarly tested the resilience of rural mental health networks in western North Carolina. The storm damaged roads and bridges, schools and even local clinics.

    This prompted a news organization, North Carolina Health News, to warn of rising “trauma, stress and isolation” among residents as providers scrambled to offer free counseling despite legal barriers stemming from licensing requirements to provide counseling across state borders. State health officials activated community crisis centers and helplines, while mobile mental health teams were dispatched from Tennessee to help those impacted by the disaster. However, state representatives stressed that without long-term investment, these critical supports risk being one-off responses.

    These events serve as a powerful reminder that while roads and buildings can often be restored quickly, emotional recovery is a slower, more complex process. Truly rebuilding requires treating mental health with the same urgency as physical infrastructure. This requires investing in strong mental health recovery systems, supporting local clinics, sustaining provider networks and integrating emotional care into recovery plans from the start.

    Finding mental health support following a disaster

    Lessons learned from previous disasters and an abundance of research show how sustained mental health supports can help people recover and build resilience.

    These six lessons are particularly helpful for finding needed mental health support following a disaster:

    • If you’re feeling overwhelmed after a disaster, you’re not alone, and help is available. Free and confidential support is offered through resources like the Disaster Distress Helpline (1-800-985-5990 or text TalkWithUs to 66746), which connects you to trained counselors 24/7.

    • Many communities offer local mental health crisis lines or walk-in centers that remain active well after the disaster passes. Check your county or state health department’s website for updated listings and information.

    • Even if physical offices are closed, many clinics now offer virtual counseling or can connect you with therapists and medication refills remotely. If you’ve seen someone before, ask if they’re still available by phone or video.

    • After major disasters, states often deploy mobile health clinics that include mental health services to shelters, churches or schools. These temporary services are free and open to the public.

    • If someone you care about is struggling, help them connect with resources in the community. Share hotline numbers, offer to help make an appointment or just let them know it’s OK to ask for support. Many people don’t realize that help is available, or they think it’s only for more “serious” problems. It’s not.

    • Mental health support doesn’t always arrive right away. Keep an eye on local news, school updates or health department alerts for new services that may become available in the weeks or months after a disaster.

    Disasters don’t just damage buildings; they disrupt lives in lasting ways.

    While emotional recovery takes time, support is available. Staying informed and sharing resources with others can help ensure that the road to recovery isn’t traveled alone.

  • Disasters don’t disappear when the storm ends – cascading hazards, from landslides to floods, are upending risk models

    Hurricane Helene lasted only a few days in September 2024, but it altered the landscape of the Southeastern U.S. in profound ways that will affect the hazards local residents face far into the future.

    Mudslides buried roads and reshaped river channels. Uprooted trees left soil on hillslopes exposed to the elements. Sediment that washed into rivers changed how water flows through the landscape, leaving some areas more prone to flooding and erosion.

    Helene was a powerful reminder that natural hazards don’t disappear when the skies clear – they evolve.

    These transformations are part of what scientists call cascading hazards. They occur when one natural event alters the landscape in ways that lead to future hazards. A landslide triggered by a storm might clog a river, leading to downstream flooding months or years later. A wildfire can alter the soil and vegetation, setting the stage for debris flows with the next rainstorm.

    I study these disasters as a geomorphologist. In a new paper in the journal Science, I and a team of scientists from 18 universities and the U.S. Geological Survey explain why hazard models – used to help communities prepare for disasters – can’t just rely on the past. Instead, they need to be nimble enough to forecast how hazards evolve in real time.

    The science behind cascading hazards

    Cascading hazards aren’t random. They emerge from physical processes that operate continuously across the landscape – sediment movement, weathering, erosion. Together, the atmosphere, biosphere and the earth are constantly reshaping the conditions that cause natural disasters.

    For instance, earthquakes fracture rock and shake loose soil. Even if landslides don’t occur during the quake itself, the ground may be weakened, leaving it primed for failure during later rainstorms.

    That’s exactly what happened after the 2008 earthquake in Sichuan Province, China, which led to a surge in debris flows long after the initial seismic event.

    Earth’s surface retains a “memory” of these events. Sediment disturbed in an earthquake, wildfire or severe storm will move downslope over years or even decades, reshaping the landscape as it goes.

    The 1950 Assam earthquake in India is a striking example: It triggered thousands of landslides. The sediment from these landslides gradually moved through the river system, eventually causing flooding and changing river channels in Bangladesh some 20 years later.

    An intensifying threat in a changing world

    These risks present challenges for everything from emergency planning to home insurance. After repeated wildfire-mudslide combinations in California, some insurers pulled out of the state entirely, citing mounting risks and rising costs among the reasons.

    Cascading hazards are not new, but their impact is intensifying.

    Climate change is increasing the frequency and severity of wildfires, storms and extreme rainfall. At the same time, urban development continues to expand into steep, hazard-prone terrain, exposing more people and infrastructure to evolving risks.

    The rising risk of interconnected climate disasters like these is overwhelming systems built for isolated events.

    Yet climate change is only part of the equation. Earth processes – such as earthquakes and volcanic eruptions – also trigger cascading hazards, often with long-lasting effects.

    Mount St. Helens is a powerful example: More than four decades after its eruption in 1980, the U.S. Army Corps of Engineers continues to manage ash and sediment from the eruption to keep it from filling river channels in ways that could increase the flood risk in downstream communities.

    Rethinking risk and building resilience

    Traditionally, insurance companies and disaster managers have estimated hazard risk by looking at past events.

    But when the landscape has changed, the past may no longer be a reliable guide to the future. To address this, computer models based on the physics of how these events work are needed to help forecast hazard evolution in real time, much like weather models update with new atmospheric data.

    Brian Yanites, June 2025

    Thanks to advances in Earth observation technology, such as satellite imagery, drone and lidar, which is similar to radar but uses light, scientists can now track how hillslopes, rivers and vegetation change after disasters. These observations can feed into geomorphic models that simulate how loosened sediment moves and where hazards are likely to emerge next.

    Researchers are already coupling weather forecasts with post-wildfire debris flow models. Other models simulate how sediment pulses travel through river networks.

    Cascading hazards reveal that Earth’s surface is not a passive backdrop, but an active, evolving system. Each event reshapes the stage for the next.

    Understanding these connections is critical for building resilience so communities can withstand future storms, earthquakes and the problems created by debris flows. Better forecasts can inform building codes, guide infrastructure design and improve how risk is priced and managed. They can help communities anticipate long-term threats and adapt before the next disaster strikes.

    Most importantly, they challenge everyone to think beyond the immediate aftermath of a disaster – and to recognize the slow, quiet transformations that build toward the next.

  • Not just a few bad apples: The Canadian Armed Forces has a nagging far-right problem

    Source: ForeignAffairs4

    The Canadian Armed Forces (CAF) is making headlines. But not, as they probably hoped, for the renewed recruiting efforts they’re about to launch. Instead, they are once again confounded by a far-right scandal.

    The latest episode is the arrest of four CAF members and ex-members. Three of them have been charged with taking concrete steps to facilitate terrorist activity and possessing prohibited firearms. A fourth man was charged with possession and storage of prohibited firearms and devices.

    The crew had allegedly been under surveillance by the federal government’s Integrated National Security Enforcement Team since 2021, most likely when equipment, weapons and ammunition began to go missing from military installations. The weapons were finally seized in January 2024, some in the personal vehicle of one of the suspects, but the group remained free for another 18 months.

    Charges against Canadian Army members in anti-government terror plot raise alarms about right-wing extremism


    As is usual with these types of efforts, a certain degree of amateurism was present at multiple stages of the alleged scheme, which may have developed on the fly. The idea that a micro-militia might successfully seize and hold territory in Canada is far-fetched at best.

    Recruitment efforts for the suspected mission, complete with propaganda and self-aggrandizing pictures of military training, took place on, you guessed it: Instagram. (We won’t publish the name of the account.)

    It might be pointed out that any large organization like the CAF inevitably represents a microcosm of society, meaning that it can’t be expected to be free of various forms of undesirable behaviour, including political extremism. But this “rotten apple” theory of far-right extremism in the CAF falls somewhat short of explaining the situation.

    Not just a ‘few rotten apples’

    First, the rotten apples seem too numerous. Just days before the recent arrests, the CAF announced on July 3 it was investigating the participation of other soldiers in a private Facebook page named the “Blue Hackle Mafia.” The page disseminated openly racist, homophobic, misogynist and antisemitic content.

    These events point to a phenomenon difficult to measure within western countries, even though it’s very real. The penetration of ideas associated with the far right within the military and law enforcement agencies is currently happening. Whether more or less structured, the emergence of underground small groups are more or less ready to “take action.”

    Second, previous reports have identified a general laissez-faire approach within the CAF regarding far-right activities. In a 2022 independent report commissioned by the CAF, the presence of white supremacist and other far-right ideologies was identified not only as a growing problem for the Army, but also one that was not being addressed.

    Similar conclusions were reached in the 1997 report on the behaviour of Canadian soldiers in Somalia, which had explicitly recommended that “the Canadian Forces establish regular liaison with anti-racist groups to obtain assistance in the conduct of appropriate cultural sensitivity training and to assist supervisors and commanders in identifying signs of racism and involvement with hate groups.” In other words, neither the concern nor the awareness is news.

    Affinity between far right and military

    At the root of the problem is a peculiar affinity between most forms of far-right ideologies and military or paramilitary/policing organizations.

    It’s absurd to simply paint such organizations as inherently far right in their nature, of course. But strict authority structures and notions of defence, fellowship, honour — as well as the projection of power through physical strength and training and the accompanying symbolism of weapons, fatigues, uniforms and campaign-like deployments — are all very appealing to far-right extremists.

    This nexus has been amply documented and leads to multiple practical implications: extremist groups trying to recruit active or retired soldiers; soldiers joining existing groups or setting up their own; veterans joining existing groups or creating their own, like the founders of Québec’s La Meute; professionally trained lone wolves, like Correy Hurren, who attempted to “arrest” Prime minister Justin Trudeau at Rideau Hall in 2020)

    Members of extremist groups also routinely try to join the military to benefit from training, which elevates their standing within the group.

    Military, former and active, and law enforcement members are to be found in multiple “militia” groups like the Three Percenters, the Proud Boys, the Oath Keepers, Diagolon and the Boogaloo movement, for instance. Some are overtly anti-government and/or anti-system, like the Veterans 4 Freedom or The Base.

    Far-right demons

    It may sound strange to think of military personnel or veterans getting involved or creating an anti-government movement when they’ve served under the flag sometimes for decades. The apparent paradox quickly disappears once we understand the manifold individual motivations that underpin their actions.

    They range from the feeling of having served a timourous government that failed to make proper use of the Armed Forces at its disposal. The absence of deployments to theatres of conflict also generates frustration among some in search of military adventure.

    A lot of young men are quickly bored with exercises that never satisfy their expeditionary spirit. The role of camaraderie, of group dynamics based on mutual aid, honour and the presence of danger, as well as mental health issues, must not be overlooked. Not to mention the idea, strong in some units, of defending a singular idea of a “fatherland” endangered by government contempt and inaction.

    What is striking in the light of the recent charges in Québec is not so much the racist and anti-semitic ideological ideas allegedly held by the accused group members. It’s the primacy given to a patriarchal ideology that explicitly targets women and gender. Fascination with Russia and the war in Ukraine waged by Vladimir Putin is also palpable.

    In short, the CAF is still wrestling with far-right demons, though in a new context of social media acceleration and global loss of confidence in democratic institutions. The situation has a high potential to undermine confidence in Canada’s Armed Forces at a time when geopolitical tensions are calling for a strengthening of its military arsenal, and first and foremost, our military human capital.

  • Want more orgasms? Choose a woman partner

    Being partnered with a woman is associated with an orgasm advantage. (Pexels/Cottonbro)

    The orgasm gap — the consistent finding that men who have sex with women have more frequent orgasms than women who have sex with men — has been shown in study after study of cisgender, heterosexual participants.

    The gap is a big one: Based on a recent Canadian study, approximately 60 per cent of women and 90 per cent of men reported reaching orgasm in their most recent sexual encounter.

    In sexually diverse samples (samples that also include women who have sex with women and men who have sex with men), the pattern becomes more nuanced but still supports a gendered orgasm gap.

    Research has shown that the gap in orgasm frequency is reduced (in other words, there is more equal orgasm frequency) in women who have sex with women (about 75 per cent), and this rate is significantly higher than in women who have sex with men (about 62 per cent). However, men as a group — regardless of who they were having sex with — still had significantly higher orgasm frequency (85 per cent) than women overall (63 per cent). Women are orgasm-disadvantaged overall and especially when they have sex with men.

    Mind the gap

    How far-reaching is the orgasm gap and what factors might be standing in the way of orgasms for all? We — a team of researchers and science journalists from the podcast Science Vsexamined orgasm frequency in a large diverse sample that included sexual (such as lesbian) and gender (such as trans) minorities and majorities, as well as racialized participants (there were no significant results with analyses focused on sexual orientation or race).

    The good news? We found that many people overall were having lots of orgasms — about two-thirds reported having orgasms almost or every time they engaged sexually.

    The not-so-great news? The orgasm gap persisted: cis men overall reported the highest orgasm frequency compared to women and gender minorities (who did not differ significantly from each other). In addition, we found that participants of all genders who engaged sexually with women reported significantly more frequent orgasms than those who engaged sexually with men. So being partnered with a woman is associated with an orgasm advantage.

    More not-so-great news was that about 17 per cent of participants reported almost never or never having orgasms during sex and that there were many factors preventing orgasms in participants. For cis women, psychological barriers — such as insecurities, mental health struggles and distractions — were prominent, as were sexual obstacles (like not receiving adequate stimulation), difficulties inherent in having orgasms (for example, they take too long and require too much effort) and not knowing why orgasms are difficult for them to have.

    Closing the gap

    So why does the orgasm gap exist and persist? One main reason is that broad sociocultural norms prioritize men’s sexual pleasure over women’s. Indeed, these norms develop from the traditional (heterosexual, western) sexual script that defines the end of sexual activity as male orgasm; importantly, women’s adherence to this script has been associated with lower sexual satisfaction.

    Women’s own degree of familiarity with their partner has also been shown to be critical in narrowing the gap.

    Another is that mainstream media feeds into narratives of sexual expectations based on gender, such that portrayals of women who do not have orgasms are much more — even readily — acceptable than portrayals of orgasmless men. This inequality is played out in sexual encounters, perpetuating the gap and contributing to complacency in addressing it.

    But there is hope: Heterosexual men’s motivation to bring their partner to orgasm and their intentional incorporation of sexual activities that increase the chance of orgasm for their partner — such as clitoral stimulation and oral sex — can help narrow (and even eradicate!) the gap. Women’s own degree of familiarity with their partner has also been shown to be help narrow the gap. Higher familiarity (think of a long-term situationship as opposed to a casual hookup) was associated with higher orgasm frequency.

    The simple act of prioritizing women’s orgasm — captured with an easy-to-remember phrase of “she comes first” — may be all that is needed to substantially narrow the orgasm gap.
