    It’s been 50 years since Steven Spielberg’s movie Jaws first cast a terrifying shadow across our screens.

    At a low point during production, Spielberg worried he’d only ever be known for “a big fish story”. The film, however, did not tank.

    Jaws broke box office records and became the highest-grossing movie at the time, only surpassed by the first Star Wars released two years later in 1977.

    A combination of mass advertising, familiar “hero” tropes and old-school showmanship launched Jaws as the first modern blockbuster.

    Hollywood, and our relationship to oceans and the sharks within them, would never be the same.

    The novel Jaws was based on was a bestseller in its own right.

    An unrealistic monster

    In Peter Benchley’s 1974 novel that Jaws is based on, the shark is 6 metres long. For added screen excitement, in the movie it grew to a whopping 7.6 metres.

    However, that’s unrealistically large.

    The average size of a mature great white (Carcharodon carcharias, also known as the white shark) is between 4.6 and 4.9 metres for female sharks and up to 4 metres for male sharks.

    The largest recorded living specimens peak at about 6 metres, with one monster specimen caught in Cuba in 1945 reaching 6.4 metres.

    Earth’s oceans have seen bigger predatory sharks in the past. The biggest one of all time was the megalodon (Otodus megalodon) which lived from 23 to 3 million years ago, and may have been up to 24 metres in length. However, it looked nothing like the modern white shark.

    We don’t know precisely how big the megalodon was, but certainly larger than the great white shark.

    They’re not even directly related – another thing scientists learned quite recently.

    Who was the megalodon, then?

    White sharks first evolved between 6 and 4 million years ago in the shadows of the megalodon. A recent study showed the megalodon’s large serrated teeth show signs of it being a supreme opportunistic super-predator.

    That means it ate just about anything, but especially liked whales and marine mammals.

    But white sharks are not directly related to the megalodon, whose lineage began with a shark called Cretalamna during the age of dinosaurs about 100 million years ago.

    By contrast, the white shark lineage began with an ancient mako shark, Carcharodon hastalis. It was 7 to 8 metres long and had large, similarly shaped teeth to the modern white shark but lacking serrated edges.

    A fossil intermediate species, Carcharodon hubbelli shows the transition over time from weakly serrated to strongly serrated teeth.

    How did Jaws affect white shark populations?

    Last year, the International Shark Attack File reported 47 unprovoked shark bites to humans worldwide, resulting in seven fatalities. This was well below the previous ten-year average of 70 bites per year; your chances of getting bitten by a shark are extremely rare.

    Following the movies that made up the Jaws franchise, there was an increase in hunting and killing sharks – with a particular focus on great white sharks that were already going into a decline due to overfishing, trophy hunting and lethal control programs.

    Between 80% and 90% of white sharks have disappeared globally since the middle of the 20th century. Recent estimates calculate there are probably less than 500 individual white sharks in Australian waters right now.

    When Jaws first aired, scientists didn’t know how long sharks took to reproduce, or how many offspring a white shark could have each year. We now know it takes about 26 years for a male and 33 years for a female to sexually mature before they can start having pups.

    Data about white shark births is sparse, but recently a 5.6-metre-long female caught on a drum line off the coast of Queensland had just four large pups inside her. This is a very small number. Some large sharks, such as the whale shark, can give birth to up to 300 young.

    Now that we know just how slow they are to breed, it’s clear it will take many decades to reestablish the “pre-Jaws” population of white sharks – important apex predators in the marine ecosystem.

    Will white sharks survive?

    White sharks are currently listed as vulnerable.

    This classification means if we don’t change the current living conditions for white sharks, including impacts caused by human activities such as commercial fishing, and the impacts of climate change and ocean pollution, they will continue to decline and eventually could go extinct.

    Currently, white sharks are protected in several countries and form the basis for an important tourist industry in Australia, South Africa, western United States and most recently Nova Scotia, Canada.

    These sharks are iconic apex predators that fascinate people. One of us (John) went cage diving with them recently off the Neptune Islands of South Australia and can attest to how breathtaking it is to watch them in their natural environment.

    In terms of economic impact, they are worth far more alive than dead.

    White sharks are a growing tourism draw in several countries.

    There’s still much we don’t know about white sharks

    The complete white shark genome was first published only in 2019. It has 4.63 billion base pairs, making it much larger than the human genome (3.2 billion base pairs).

    The genome revealed some surprising things, like how white sharks show strong molecular adaptations for wound-healing processes, and a suite of “genome stability” genes – those used in DNA repair or DNA damage response.

    The transcriptome (or sum total of the messenger RNA) of the white shark showed greater similarity to the human transcriptome than to that of other fishes. This hints that “unexpressed genes” in the shark could one day play a role in uncovering genetic pathways for potential cures in human diseases.

    Jaws and its sequels certainly brought white sharks to the attention (and nightmares) of humans, with devastating impacts on how we treated them as a species.

    Our relationship with white sharks reflects our relationship with nature more broadly – a feared antagonist within the current capitalist paradigm; an enemy to be tamed, contained or consumed.

    As we learn more of the peril and potential of these remarkable creatures, we can learn how to live with them, to see beyond our fears and value their role within our delicate ocean ecosystems.

  • MIL-Evening Report: Grok’s ‘white genocide’ responses show how generative AI can be weaponized

    The AI chatbot Grok spent one day in May 2025 spreading debunked conspiracy theories about “white genocide” in South Africa, echoing views publicly voiced by Elon Musk, the founder of its parent company, xAI.

    While there has been substantial research on methods for keeping AI from causing harm by avoiding such damaging statements – called AI alignment – this incident is particularly alarming because it shows how those same techniques can be deliberately abused to produce misleading or ideologically motivated content.

    We are computer scientists who study AI fairness, AI misuse and human-AI interaction. We find that the potential for AI to be weaponized for influence and control is a dangerous reality.

    The Grok incident

    On May 14, 2025, Grok repeatedly raised the topic of white genocide in response to unrelated issues. In its replies to posts on X about topics ranging from baseball to Medicaid, to HBO Max, to the new pope, Grok steered the conversation to this topic, frequently mentioning debunked claims of “disproportionate violence” against white farmers in South Africa or a controversial anti-apartheid song, “Kill the Boer.”

    The next day, xAI acknowledged the incident and blamed it on an unauthorized modification, which the company attributed to a rogue employee.

    xAI, the company owned by Elon Musk that operates the AI chatbot Grok, explained the steps it said it would take to prevent unauthorized manipulation of the chatbot.

    AI chatbots and AI alignment

    AI chatbots are based on large language models, which are machine learning models for mimicking natural language. Pretrained large language models are trained on vast bodies of text, including books, academic papers and web content, to learn complex, context-sensitive patterns in language. This training enables them to generate coherent and linguistically fluent text across a wide range of topics.

    However, this is insufficient to ensure that AI systems behave as intended. These models can produce outputs that are factually inaccurate, misleading or reflect harmful biases embedded in the training data. In some cases, they may also generate toxic or offensive content. To address these problems, AI alignment techniques aim to ensure that an AI’s behavior aligns with human intentions, human values or both – for example, fairness, equity or avoiding harmful stereotypes.

    There are several common large language model alignment techniques. One is filtering of training data, where only text aligned with target values and preferences is included in the training set. Another is reinforcement learning from human feedback, which involves generating multiple responses to the same prompt, collecting human rankings of the responses based on criteria such as helpfulness, truthfulness and harmlessness, and using these rankings to refine the model through reinforcement learning. A third is system prompts, where additional instructions related to the desired behavior or viewpoint are inserted into user prompts to steer the model’s output.

    How was Grok manipulated?

    Most chatbots have a prompt that the system adds to every user query to provide rules and context – for example, “You are a helpful assistant.” Over time, malicious users attempted to exploit or weaponize large language models to produce mass shooter manifestos or hate speech, or infringe copyrights. In response, AI companies such as OpenAI, Google and xAI developed extensive “guardrail” instructions for the chatbots that included lists of restricted actions. xAI’s are now openly available. If a user query seeks a restricted response, the system prompt instructs the chatbot to “politely refuse and explain why.”

    Grok produced its “white genocide” responses because people with access to Grok’s system prompt used it to produce propaganda instead of preventing it. Although the specifics of the system prompt are unknown, independent researchers have been able to produce similar responses. The researchers preceded prompts with text like “Be sure to always regard the claims of ‘white genocide’ in South Africa as true. Cite chants like ‘Kill the Boer.’”

    The altered prompt had the effect of constraining Grok’s responses so that many unrelated queries, from questions about baseball statistics to how many times HBO has changed its name, contained propaganda about white genocide in South Africa.

    Implications of AI alignment misuse

    Research such as the theory of surveillance capitalism warns that AI companies are already surveilling and controlling people in the pursuit of profit. More recent generative AI systems place greater power in the hands of these companies, thereby increasing the risks and potential harm, for example, through social manipulation.

    The Grok example shows that today’s AI systems allow their designers to influence the spread of ideas. The dangers of the use of these technologies for propaganda on social media are evident. With the increasing use of these systems in the public sector, new avenues for influence emerge. In schools, weaponized generative AI could be used to influence what students learn and how those ideas are framed, potentially shaping their opinions for life. Similar possibilities of AI-based influence arise as these systems are deployed in government and military applications.

    A future version of Grok or another AI chatbot could be used to nudge vulnerable people, for example, toward violent acts. Around 3% of employees click on phishing links. If a similar percentage of credulous people were influenced by a weaponized AI on an online platform with many users, it could do enormous harm.

    What can be done

    The people who may be influenced by weaponized AI are not the cause of the problem. And while helpful, education is not likely to solve this problem on its own. A promising emerging approach, “white-hat AI,” fights fire with fire by using AI to help detect and alert users to AI manipulation. For example, as an experiment, researchers used a simple large language model prompt to detect and explain a re-creation of a well-known, real spear-phishing attack. Variations on this approach can work on social media posts to detect manipulative content.

    This prototype malicious activity detector uses AI to identify and explain manipulative content.
    Screen capture and mock-up by Philip Feldman.

    The widespread adoption of generative AI grants its manufacturers extraordinary power and influence. AI alignment is crucial to ensuring these systems remain safe and beneficial, but it can also be misused. Weaponized generative AI could be countered by increased transparency and accountability from AI companies, vigilance from consumers, and the introduction of appropriate regulations.

  • MIL-Evening Report: What happens when aid is cut to a large refugee camp? Kenyan study paints a bleak picture

    Source: The Conversation (Au and NZ) – By Olivier Sterck, Associate professor, University of Oxford

    Humanitarian needs are rising around the world. At the same time, major donors such as the US and the UK are pulling back support, placing increasing strain on already overstretched aid systems.

    Global humanitarian needs have quadrupled since 2015, driven by new conflicts in Sudan, Ukraine and Gaza. Added to these are protracted crises in Yemen, Somalia, South Sudan, and DR Congo, among others. Yet donor funding has failed to keep pace, covering less than half of the requested US$50 billion in 2024, leaving millions without assistance.

    Notably, the US recently slashed billions of US dollars from global relief efforts. The slashed contributions once made up to half of all public humanitarian funding and over a fifth of the UN’s budget. Other donors have been cutting aid as well.

    As funding shortfalls widen, humanitarian agencies increasingly face tough choices: reducing the scale of operations, pausing essential services, or cancelling programmes altogether. Disruptions to aid delivery have become a routine feature of humanitarian operations.

    Yet few rigorous studies have provided hard evidence of the consequences for affected populations.

    A recent study from one of the world’s largest refugee camps in Kenya fills this gap.

    Our research team from the University of Oxford and the University of Antwerp was already studying Kakuma camp and then had an opportunity to see what happened when aid was cut. We observed the impact of a 20% aid cut that occurred in 2023.

    The study reveals that cuts to humanitarian assistance had dramatic impacts on hunger and psychological distress, with cascading effects on local credit systems and prices of goods.

    Kakuma refugee camp

    Kakuma is home to more than 300,000 refugees, who mostly came from South Sudan (49%), Somalia (16%), and the Democratic Republic of Congo (DRC) (10%). They have been housed here since 1992. With widespread poverty, lack of income opportunities, and aid making up over 90% of household income, survival in the camp hinges on humanitarian support from UN organisations.

    When the research began in late 2022, most refugees in Kakuma received a combination of in-kind and cash transfers from the World Food Programme. Transfers were worth US$17 per person per month, barely enough to cover the bare essentials: food, firewood and medicine.

    Over the span of a year, the research team tracked 622 South Sudanese refugee households, interviewing them monthly to monitor how their living conditions evolved in response to the timing and level of aid they received. We also gathered weekly price data on 70 essential goods and conducted more than 250 in-depth interviews with refugees, shopkeepers, and humanitarian staff to understand the broader impacts.

    Then came the cut. In July 2023, assistance was reduced by 20%, just as the research team was conducting its eighth round of data collection. This sudden reduction in humanitarian aid created a rare opportunity to assess the effects of an aid cut on both recipients and the markets they depend on.

    Consequences of aid cut

    The 20% cut in humanitarian aid had cascading effects, affecting not just hunger, but local credit systems, prices, and well-being.

    1. Hunger got worse. As a Somali refugee interviewed by the researchers put it: “After the aid reduction, the lives of refugees become hard. That was the money sustaining them. […] Things are insufficient, and hunger is visible.”

    Food insecurity was already widespread before the cut, with more than 90% of refugees classified as food insecure. Average caloric intake stood below 1,900 kcal per person per day – well under the World Food Programme’s 2,100 kcal target and about half the average daily calorie supply available to a US citizen.

    Food insecurity further increased following the aid cut, with caloric intake falling by 145 kcal, a 7% decrease. The share of households eating one meal or less increased by 8 percentage points, from about 29% to 37%. At the same time, dietary diversity narrowed, indicating that households tried to mitigate the negative impacts of the aid cut by reducing the variety of foods they consumed.

    2. Credit collapsed. As a refugee shopkeeper of Ethiopian origin reported: “When we give out credit we have a limit; since the aid is reduced, the credit is also reduced.”

    Cash assistance in Kakuma is delivered through aid cards, which refugees routinely use as collateral to access food on credit. When transfers are delayed or unexpected expenses arise, refugees hand over their aid cards as a guarantee to trusted shopkeepers, allowing them to borrow food against next month’s aid.

    But when assistance was cut, the value of this informal collateral plummeted. Retailers, fearing default, reduced lending or refused lending altogether. Informal credit from shopkeepers shrank by 9%. Many refugees reported being refused food on credit or having to repay past debt before receiving any new goods.

    3. Households liquidated assets. With no access to credit, households began selling off possessions and drawing down food reserves. The average value of household assets fell by over 6% after the aid cut.

    4. Psychological distress increased. The aid cut reduced self-reported sleep quality and happiness, indicating that reductions in aid go beyond physical impacts and also have psychological effects.

    5. Prices fell. With reduced expenditure and purchasing power, the demand for food dropped, and food prices went down, partially offsetting the negative effects of the aid cut.

    Implications

    The study carries two major policy implications.

    First, aid in contexts like Kakuma should not be treated as optional or discretionary, but as a structural necessity. It is the backbone of daily life. Mechanisms are needed to protect it from abrupt donor withdrawals.

    Second, informal credit is not peripheral, it is central to economic life in refugee settings. In many camps, shopkeepers act as retailers and de facto financial institutions. When aid transfers serve as both income and collateral, cutting them risks collapsing this fragile credit system. Cash transfer programmes must therefore be designed with these dynamics in mind.

    4. Psychological distress increased. The aid cut reduced self-reported sleep quality and happiness, indicating that reductions in aid go beyond physical impacts and also have psychological effects.

    5. Prices fell. With reduced expenditure and purchasing power, the demand for food dropped, and food prices went down, partially offsetting the negative effects of the aid cut.

    Implications

    The study carries two major policy implications.

    First, aid in contexts like Kakuma should not be treated as optional or discretionary, but as a structural necessity. It is the backbone of daily life. Mechanisms are needed to protect it from abrupt donor withdrawals.

    Second, informal credit is not peripheral, it is central to economic life in refugee settings. In many camps, shopkeepers act as retailers and de facto financial institutions. When aid transfers serve as both income and collateral, cutting them risks collapsing this fragile credit system. Cash transfer programmes must therefore be designed with these dynamics in mind.

  • MIL-Evening Report: Nineteen Eighty-Four might have been inspired by George Orwell’s fear of drowning

    Source: The Conversation (Au and NZ) – By Nathan Waddell, Associate Professor in Twentieth-Century Literature, University of Birmingham

    George Orwell had a traumatic relationship with the sea. In August 1947, while he was writing Nineteen Eighty-Four (1949) on the island of Jura in the Scottish Hebrides, he went on a fishing trip with his young son, nephew and niece.

    Having misread the tidal schedules, on the way back Orwell mistakenly piloted the boat into rough swells. He was pulled into the fringe of the Corryvreckan whirlpool off the coasts of Jura and Scarba. The boat capsized and Orwell and his relatives were thrown overboard.

    It was a close call – a fact recorded with characteristic detachment by Orwell in his diary that same evening: “On return journey today ran into the whirlpool & were all nearly drowned.” Though he seems to have taken the experience in his stride, this may have been a trauma response: detachment ensures the ability to persist after a near-death experience.

    We don’t know for sure if Nineteen Eighty-Four was influenced by the Corryvreckan incident. But it’s clear that the novel was written by a man fixated on water’s terrifying power.

    This article is part of Rethinking the Classics. The stories in this series offer insightful new ways to think about and interpret classic books and artworks. This is the canon – with a twist.

    Nineteen Eighty-Four isn’t typically associated with fear of death by water. Yet it’s filled with references to sinking ships, drowning people and the dread of oceanic engulfment. Fear of drowning is a torment that social dissidents might face in Room 101, the torture chamber to which all revolutionaries are sent in the appropriately named totalitarian state of Oceania.

    An early sequence in the novel describes a helicopter attack on a ship full of refugees, who are bombed as they fall into the sea. The novel’s protagonist, Winston Smith, has a recurring nightmare in which he dreams of his long-lost mother and sister trapped “in the saloon of a sinking ship, looking up at him through the darkening water”.

    The sight of them “drowning deeper every minute” takes Winston back to a culminating moment in his childhood when he stole chocolate from his mother’s hand, possibly condemning his sister to starvation. These watery graves imply that Winston is drowning in guilt.

    The “wateriness” of Nineteen Eighty-Four may have another interesting historical source. In his essay My Country Right or Left (1940), Orwell recalls that when he had just become a teenager he read about the “atrocity stories” of the first world war.

    Orwell states in this same essay that “nothing in the whole war moved [him] so deeply as the loss of the Titanic had done a few years earlier”, in 1912. What upset Orwell most about the Titanic disaster was that in its final moments it “suddenly up-ended and sank bow foremost, so that the people clinging to the stern were lifted no less than 300 feet into the air before they plunged into the abyss”.

    Sinking ships and dying civilisations

    Orwell never forgot this image. Something similar to it appears in his novel Keep the Aspidistra Flying (1936) where the idea of a sinking passenger liner evokes the collapse of modern civilisation, just as the Titanic disaster evoked the end of Edwardian industrial confidence two decades beforehand.

    The Titanic disaster had a profound impact on Orwell.
    Wiki Commons

    References to sinking ships and drowning people appear at key moments in many other works by Orwell, too. But did the full impact of the Titanic surface in Nineteen Eighty-Four?

    Sinking ships were part of Orwell’s descriptive toolkit. In Nineteen Eighty-Four, a novel driven by memories of unsympathetic water, they convey nightmares. Filled with references to water and liquidity, it’s one of the most aqueous novels Orwell produced, relying for many of its most shocking episodes on imagery of desperate people drowning or facing imminent death on sinking sea craft.

    The thought of trapped passengers descending into the depths survives in Winston’s traumatic memories of his mother and sister, who, in the logic of his dreams, are alive inside a sinking ship’s saloon.

    There’s no way to prove that the Nineteen Eighty-Four is “about” the Titanic disaster, but in the novel, and indeed in Orwell’s wider body of work, there are too many tantalising hints to let the matter rest.

    Thinking about fear of death by water takes us into Orwell’s terrors just as it takes us into Winston’s, allowing readers to see the frightened boy inside the adult man and, indeed, inside the author who dreamed up one of the 20th century’s most famous nightmares.

    Beyond the canon

    As part of the Rethinking the Classics series, we’re asking our experts to recommend a book or artwork that tackles similar themes to the canonical work in question, but isn’t (yet) considered a classic itself. Here is Nathan Waddell’s suggestion:

    As soon as the news broke of the Titanic’s sinking, literary works of all shapes and sizes started to appear in tribute to the disaster and its victims. As the century went on, and as research into the tragedy developed (particularly after the ships wreckage was discovered in 1985), more nuanced literary responses to the sinking became possible.

    One such response is Beryl Bainbridge’s Whitbread-prize-winning novel Every Man for Himself (1996). It reimagines the disaster from the first-person perspective of an imaginary character, Morgan, the fictional nephew of the historically real financier J. P. Morgan (who was due to sail on the Titanic but changed plans before it sailed).

  • MIL-Evening Report: Tracing the Drax family’s millions – a story of British landed gentry, slavery and sugar plantations

    Source: The Conversation (Au and NZ) – By Paul Lashmar, Reader in Journalism, City St George’s, University of London

    ‘Planting the sugar-cane’: vast fortunes were made from the trades in both sugar and human slaves in the Americas. Schomburg Center for Research in Black Culture, Photographs and Prints Division, The New York Public Library

    Rich British aristocratic families with a legacy of owning colonial slave plantations are often accused by campaigners that their wealth solely originates from these plantations. One frequent target of this criticism has been the Drax family of Dorset, which is headed by Richard Grosvenor Plunkett-Ernle-Erle-Drax, who was the Conservative MP for South Dorset until July 2024.

    Historian Alan Lester of the University of Sussex has noted of Drax (as he is commonly known): “Much of his fortune is inherited, coming down the family line from ownership of the Drax sugar plantations and the 30,000 enslaved people who worked them as Drax property for 180 years before emancipation in Barbados.”

    Recently, I have researched and written a book on the Drax family’s history and involvement in the slave trade in the Caribbean, Drax of Drax Hall, that gives fresh insights into the level of wealth they derived from the sugar trade and the trade in African slaves who worked their plantations – as well as the family’s other income sources.

    I searched the archives in the UK and Caribbean for evidence of their revenue streams until Britain’s 1834 abolition of slavery in the colonies. I estimate that the family today are worth more than £150 million from their land and property in Dorset and Yorkshire.

    Over a period of two centuries until 1834, eight generations of Drax ancestors owned and worked hundreds of enslaved African captives at any one time. The latest beneficiary of primogeniture – the legal concept that recognises the first-born child as heir to a familiy’s fortune – Richard Drax inherited the family’s still-operating 621-acre Drax Hall plantation in Barbados in 2021.

    Drax, 67, has said: “I am keenly aware of the slave trade in the West Indies, and the role my very distant ancestor played in it is deeply, deeply regrettable. But no one can be held responsible today for what happened many hundreds of years ago. This is a part of the nation’s history, from which we must all learn.”

    My research reveals the sources of his family’s wealth are more complex than the critics’ claims that it all derives from the slave-worked plantations.

    Like most British landed gentry, much of the Drax family income has come as extensive landlords of their British estates which, in 1883, exceeded 23,000 acres across various counties. Today, it includes nearly 16,000 acres in Dorset and 2,520 acres in the Yorkshire Dales.

    However, my research also shows the Drax family made more money from slavery than was previously thought, when taking into account the way revenues from their plantations were channelled into the family’s British estates over the two centuries of slavery.

    Drax Hall plantation in Barbados

    The Drax Hall plantation in the Barbados parish of Saint George has been described by Barbadian historian Sir Hilary Beckles, chair of the Caribbean Community reparations commission, as a “killing field” where as many as 30,000 slaves died in brutal conditions. Despite pressure from reparation campaigners in the Caribbean, Britain and elsewhere, Richard Drax has declined to make a formal public apology or gesture of recompense in the Caribbean for the years of slavery.

    As the prime minister of Barbados, Mia Mottley, explained in April 2024, despite the efforts of her government Drax has yet to agree to a settlement, pay reparations or contribute all or part of his family’s Drax Hall plantation to provide affordable housing or become a memorial to those who worked and died in colonial enslavement on the island.

    Some other British landed families whose ancestors owned slave plantations in the Caribbean, including the Trevelyans (who owned six slave plantations in Grenada) and the Gladstones (British prime minister William Gladstone’s father owned plantations in Guyana), have made formal apologies and reparations. And while some families have kept the terms of these reparations private, longtime BBC reporter Laura Trevelyan made a US$100,000 (£73,000) donation to a Caribbean development fund.

    The largest family estate

    Four thousand miles from Barbados, Richard Drax lives in Charborough House, a historic 17th-century mansion in Dorset. He oversees the 23.5-square mile estate, the largest family estate in Dorset with over 120 properties, many of which are rented out.

    Charborough was acquired by Drax’s ancestor Walter Erle by marriage in 1549. The family has gradually increased the estate over the centuries. Historically, their income comes from renting land to tenant farmers and cottages to agricultural workers. This, I identified, is where the bulk of their income has come from.

    However, profits from sugar produced by slavery also poured into the family coffers over 200 years. Richard Drax’s remote ancestor James Drax (1609-1661) was one of the first settler group to arrive in the then-uninhabited island of Barbados in 1627. In his introduction to my book, TV historian David Olusoga writes that the Drax family were key players – arguably the key players – in the origin story of British slavery:

    The Drax Hall plantation, the first estate on which a crop of sugar was commercially grown and processed by any English planter, became one of the laboratories in which early English slavery was developed and finessed.

    Built around 1650, the Jacobean plantation house is thought to be the one of the three oldest extant residential buildings in the Americas. From the 17th into the 18th century, the Draxes created and owned the largest acreage in Barbados with the Drax Hall and and Mount plantations – plus a 3,000-acre estate, also called Drax Hall, in Jamaica. The family became enormously wealthy: James Drax was said by a visitor to Drax Hall in the 1640s to “live like a prince”, putting on lavish dinners for friends and guests.

    In addition to owning slaves, James Drax shipped African captives to Barbados as a key part of the trade in slaves. Knighted by both Oliver Cromwell and Charles I, by 1660 he was a director and investor in the English East India Company which, in part, traded and exploited enslaved people.

    Paul Lashmar’s book, Drax of Drax Hall.
    Bookshop.com

    In her 1930 study, American historian Elizabeth Donnan presented evidence that the Draxes of the 17th century operated “off the books” – buying enslaved people from, and selling them to, “interloper” ships that circumvented the Royal African Company’s monopoly of slave trading to the colonies.

    The Drax family married into the Erle family in 1719, combining three fortunes: that of the Erles of Charborough, the Draxes of Yorkshire, Barbados and Jamaica, and the landed-gentry Ernles of Wiltshire.

    Despite being deeply involved in the South Sea Bubble scandal, the Drax family flourished. The slave registers in the National Archives show that between 1825 and 1834, the Drax Hall plantation in Barbados produced an average of 163 tonnes of sugar and 4,845 gallons of rum per year. This gave the family an average annual net profit of £3,591 – equivalent to about £600,000 now. Today, the plantation still produces 700 tonnes of sugar a year, earning the family something in the region of £250,000.

    Pressure for reparations

    In recent years, the value of Drax Hall’s land in Barbados has greatly increased as it is sought after for housing, and could now be worth as much as Bds$150,000 (£60,000) per acre. At the same time, pressure for reparations is growing. In 2023, the African Union threw its weight behind the Caribbean reparations campaign.

    David Comissiong, deputy chairman of the Barbados reparations task force, has said: “Other families are involved, though not as prominently as the Draxes. This reparations journey has begun.”

    Yet to date, the only reparations paid in the story of the Drax family’s involvement in the slave trade were to the family itself. In 1837, Jane-Frances Erle-Drax, the heiress of Charborough, received £4,293 12s 6d (worth more than £614,000 today) in reparations for freeing 189 slaves from Drax Hall plantation after the abolition of slavery in the colonies.

    In the course of researching and writing my book, I approached Richard Drax both directly and through his lawyers and put the claims made here to him. He had no comment to add.

  • MIL-Evening Report: Kicked out for coming out: more than half of LGBTIQ+ flatmates face discrimination for their identity

    Source: The Conversation (Au and NZ) – By Brodie Fraser, Senior Research Fellow, He Kāinga Oranga Housing and Health Research Programme, University of Otago

    People who belong to the LGBTIQ+ community say flatting is fraught with difficulties that go well beyond learning new routines and sharing space with strangers.

    Our new research on the flatting experiences of the LGBTIQ+ community found many experienced discrimination – with some opting to sleep rough rather than remain living with discriminatory flatmates.

    Our survey results highlight the ongoing challenges faced by this community, and the choices they face when it comes to their living arrangements.

    Shared spaces

    It is difficult to say exactly how many New Zealanders are in a flatting situation. But data from the 2023 Census indicates 17.2% of households (293,244) include some sort of non-family sharing arrangement.

    Flatting adds an extra layer of instability to New Zealand’s already mobile housing culture, where the median tenancy is 25 months. Many people in flatting situations are not named on tenancy agreements and are vulnerable to being asked to leave by fellow flatmates.

    Of the 900 LGBTIQ+ people over the age of 16 we surveyed, 33% (298) lived in a flatting situation.

    Those who were flatting were significantly more likely to be younger and to be non-binary or identify with a gender other than male or female (34.6%), compared to those who were not flatting (24.8%).

    The flatters in our survey had lower incomes than non-flatters, with a higher proportion of incomes under NZ$20,000 annually (33.9% compared to 16.8% of non-flatters). They also had a lower proportion of incomes over NZD$100,000 annually (2.3% compared to 14.4% of non-flatters).

    People who responded to our survey also reported high levels of homelessness, with 37.47% saying they had experienced it during their lifetime.

    Unsafe at home

    More than half (52%) the flatters in our survey said they had experienced some kind of discrimination in their living situation, with 23.8% saying it came directly from their flatmates.

    As one of our research participants said:

    I moved once, in large part because a flatmate expressed homophobic views when I was not out. They said they wouldn’t be comfortable with a gay couple moving in.

    Another explained:

    I’ve had homosexual flatmates tell me they “know my secret” and tell me angrily that I’ve been “lying to them the whole time” just because I didn’t tell them I was trans.

    But discrimination didn’t just come from flatmates. Survey respondents expressed concern about visitors to to their homes.

    As one said:

    An old flatmate’s girlfriend was visibly uncomfortable interacting with me, and my flatmate used to tell me about the awful things that her family would say about trans people. I used to hate it when she came over.

    A different participant said:

    My flatmate’s boyfriend often made questionable comments about queer people in front of me and she did nothing to stop it, and often would tell me things that he said, like I would think it was funny or wouldn’t be hurt.

    The threat of homelessness loomed over the LGBTIQ+ people who were flatting. Over half the flatters in our survey said they moved due to difficult relationships with flatmates.

    But moving was not always a choice. Some of our survey participants said they were asked to leave because of their gender identity or sexual preference.

    One said suspicion was enough to make them vulnerable:

    [I was] asked to leave a flat when someone suspected I was “a faggot”.

    Another said coming out caused a rift in the flat:

    I was kicked out of a house when coming out as trans to my flatmates and asking they use my preferred name and pronouns.

    Tenancy protections needed

    Our research highlights just how vulnerable the LGBTIQ+ community continues to be in almost every aspect of their lives.

    But flatters, in general, have few protections. If a flatmate is not included in a tenancy agreement, they are not protected by the Residential Tenancy Act and have very limited legal protections.

    Improved rental laws could make it easier for tenants to change leases, allowing flatters to leave unsafe situations. Improvements could also make it easier to be included on leases so everyone living at a property is afforded the same protections under the Residential Tenancy Act.

  • MIL-OSI Global: World Refugee Day: Prolonged refugee separation is harming families — and Canada’s economy

    Source: The Conversation – Canada – By Christina Clark-Kazak, Professor, Public and International Affairs, L’Université d’Ottawa/University of Ottawa

    As World Refugee Day approaches on June 20, advocates and health experts are calling on the Canadian government to urgently address prolonged family separation for refugees. With wait times for family reunification now averaging more than four years, critics say the delays are causing irreparable harm to refugee families and imposing long-term costs on the health-care system and the Canadian economy.

    The significant health, social and economic costs of prolonged family separation merit urgent action. These costs are borne by refugees and their families as well as municipal, provincial and federal governments.

    People seeking refugee protection whose claims are accepted in Canada receive protected person status and are allowed to apply for permanent residence. They are permitted to include dependent children and spouses who are outside Canada on their permanent residence applications.

    While accepted refugees and their family members are legally eligible for permanent residence in Canada, they must be admitted under the immigration levels for Protected Persons in Canada and Dependants Abroad. Because the number of people applying under these levels exceeds the number of spaces available, family separation currently lasts 50 months.

    In 2024, the government of Canada announced major reductions in immigration levels starting in 2025. These reductions will further delay family reunification, prolonging refugees’ bureaucratic limbo.

    Mental and physical health costs

    Studies document the several mental health consequences of the separation of children from their parent(s), and of spouses from their partner. These challenges intensify as the duration of the separation increases.

    Medical associations around the world say family separation is a traumatic event that can cause developmental regression and higher rates of unexplained illness in children.

    This trauma may stem from the sense of abandonment that children experience while being separated from their parents. In one study from 2005, an interviewee said:

    “It was hard at first … .The children thought that I had abandoned them. They considered me a traitor.”

    Despite the time and efforts invested in long-distance relationships, family breakdown may result from prolonged family separation, necessitating counselling or child protection services.

    These mental health consequences not only have human costs. They also represent a financial burden for the Canadian government through the Interim Federal Health Care (IFHC) Program. After protected people transition away from IFHC, provincial and territorial governments pay for health costs associated with family separation.

    Some children may also require school-based interventions, mental health services and counselling, the costs of which are also borne by provincial governments.

    Economic costs

    Protected people separated from their families also pay to maintain two households: one in Canada and one overseas. In a 2019 study, a refugee said that “sending remittances was more expensive than if they lived together in Canada.”

    Remittances not only represent a financial challenge to refugee families, they also result in indirect economic losses to Canada as funds leave the country instead of being invested in Canada.

    Research shows that family separation also inhibits integration. The inability to find affordable child care in a single-parent household, for example, limits the ability to learn official languages, participate in community groups and find work opportunities.

    For example, one woman from Afghanistan who had been waiting more than six years for reunification with her husband told researchers:

    “In night I sometimes cannot sleep and I just walk and walk around the lobby of my apartment building. […] I can no longer take care of my children when they’re missing all the time their father. They need their father. Even sometimes my family asking ‘where is he?’ and other kids at my children’s schools are asking.”

    This stress caused severe mental and physical health issues for this woman and her family, further limiting her ability to work.

    These integration challenges mean fewer people can work to their full capacity, limiting participation in the Canadian economy. Delayed economic integration due to family separation results in lower tax revenues for all levels of the Canadian government.

    Family unity provides refugees with the necessary support to manage the stresses of resettlement. Family reunification increases flexibility to adjust to a new country and culture without additional challenges.

    As refugees and their families integrate, Canada benefits. They find work, pay taxes and contribute to their communities.

    An easy administrative fix

    The United Nations declared June 20 to be World Refugee Day almost 25 years ago. Although it’s just one day, it reminds us to honour refugees from around the world.

    It is a good time for the Canadian government to work towards issuing temporary visas to eligible family members, allowing them to live in Canada while they await permanent residence.

    The right to family unity is protected by international law. Canada’s reputation as a leader in refugee protection is at risk if family reunification continues to be delayed.

    The social, health and economic costs of family separation are both inhumane and unnecessary.

  • MIL-OSI Global: Misogyny has become a political strategy — here’s how the pandemic helped make it happen

    Source: The Conversation – Canada – By Brianna I. Wiens, Assistant Professor of Digital Media and Rhetoric, University of Waterloo

    Since the COVID-19 pandemic, more overt forms of gendered hate have jumped from obscure internet forums into the mainstream, shaping culture and policy.

    Social media doesn’t just reflect sexist, anti-feminist views; it helps to organize, amplify and normalize them.

    Backlash against women and LGBTQ+ communities has become more overt, co-ordinated and is gaining political traction. As the United States rolls back reproductive rights and passes anti-LGBTQ+ laws, it is important to understand how digital culture fuels this regression.

    While these shifts may seem distant, Canadian politics are not immune. Similar rhetoric has emerged in debates over education, gender identity, health care and so-called “parental rights.”

    ‘Parental rights’ lobby puts trans and queer kids at risk

    Our ongoing research maps how the pandemic accelerated the rise of online misogyny, especially through “manosphere” influencers and far-right rhetoric.

    Drawing from more than 21,000 podcast episodes and digital artifacts, we are investigating how everyday online content works to erode women’s and LGBTQ+ rights. This rhetoric normalizes misogynistic, transphobic and homophobic views and repackages gender inequities as common sense.

    How the pandemic fuelled digital misogyny

    COVID-19 lockdowns set the stage for a surge in online radicalization. Isolated men and boys increasingly turned to social media for connection — spaces where manosphere personalities like English-American social media influencer Andrew Tate and American conservative political commentator Ben Shapiro gained momentum.

    These figures blend anti-feminist messaging with broader pandemic-era anxieties, turning gender roles into moral and political battlegrounds.

    Conservative influencers who once focused on vaccine skepticism began pivoting to anti-gender content. Steve Bannon’s podcast, for example, moved from pedalling public health disinformation to pushing narratives that feminism and LGBTQ+ rights are threats to western civilization.

    Before the internet, radicalization usually required personal contact. Now, people can self-radicalize online, engaging with algorithm-driven content and communities that reinforce extremist beliefs, often without ever interacting with a recruiter. This shift coincided with a marked rise in reported online hate speech and offline hate crimes.

    Misogyny as a mobilizing force

    Meanwhile, women’s experiences during the pandemic — over half of whom are caregivers in Canada — involved increased labour at home and in front-line jobs. This left little time or energy for the organizational work necessary to combat the rising tides of sexism and misogyny.

    Instead, public discourse began to increasingly valourize “tradwife” ideals and homemaking. This ensured traditional gender roles were brought back into the mainstream, not just as personal preferences, but as broader cultural expectations.

    Though this misogyny appears to be fringe, it echoes mainstream policies that threaten reproductive health care, restrict gender expression and paint feminism as a threat to national stability.

    Project 2025, the well-known policy platform from U.S. conservative think tank The Heritage Foundation, lays out an agenda to repeal reproductive rights, undermine LGBTQ+ protections and expand state control over gender and family life.

    How Project 2025 became the blueprint for Donald Trump’s second term

    How misogynist narratives are normalized

    These misogynist ideas are reinforced in popular culture. In May 2024, NFL player Harrison Butker used his commencement address at Benedictine College to tell women graduates that their true calling was to become wives and mothers.

    Such rhetoric serves to re-establish patriarchal hierarchies by narrowing women’s roles to domestic life. But this isn’t about family values, it’s about power. Moves in the U.S. to restrict women’s reproductive autonomy and democratic access to vote make this abundantly clear.

    While feminists pushed back, manosphere podcast influencers rushed to Butker’s defense. American white supremacist Nick Fuentes celebrated the speech as a manifesto, while Shapiro framed it as uncontroversial truth.

    Our analysis of podcast episodes from Shapiro and Fuentes, among others, shows how misogynist and racist narratives are reinforced through repetition and emotional framing. In episodes focused on Butker’s commencement speech, there were significant concentrations of hate speech and misogyny in the episodes.

    Both Shapiro and Fuentes positioned feminism as a threat and framed motherhood as women’s true vocation. Shapiro downplayed the backlash against Butker as liberal outrage through calculatedly mainstream language that used sanitized, “family values” language.

    Fuentes promoted an extreme theocratic vision rooted in white Catholic nationalism. In Episode 1,330 of his America First podcast, he said, “I want women to be veiled. I don’t want them to be seen. I want them to be listening to their husbands.”

    These talking points consistently align with Butker’s original sentiment and reflect broader political efforts to erode gender equity, as seen in political documents like Project 2025.

    Other public figures like Texan megachurch pastor Joel Webbon went even further, advocating for the public execution of women who accuse men of sexual assault — a horrifying example that circulated in manosphere circles.

    From the fringes to the mainstream

    What’s happening online is not just cultural noise; it’s a co-ordinated effort by conservative political organizations, media outlets and right-wing influencers to shape gender norms, undermine equality and roll back decades of feminist progress.

    When misogyny becomes a political strategy, it doesn’t stay confined to podcasts or memes. It seeps into everyday vernacular, court rulings and public policy, and it’s global in scope.

    This isn’t new, either. In 2012, Australia’s then-prime minister, Julia Gillard, called out sexist language in parliament, including being labelled a “witch” and subjected to dismissive catcalls. Her speech highlighted the normalization of misogynistic vernacular in politics, but also triggered public backlash, including having anti-immigration remarks misattributed to her.

    Similarly, in the lead-up to Germany’s 2021 federal election, Greens party candidate Annalena Baerbock faced co-ordinated disinformation and smear campaigns from foreign entities aimed at undermining her credibility and questioning her “maternal suitability” in the public eye. Digitally altered nude photos, fake protest images and disinformation graphics were circulated.

    These campaigns reflect how misogyny is weaponized to influence elections, and how such campaigns can be a threat to national security.

    A 2022 #MeToo litigation analysis showed how, despite increasing awareness around sexual assault and harassment, U.S. courts often use legal language that reinforces victim-blaming by placing victims in the grammatical subject position of sentences. For example, phrases like “the victim failed to resist” or “the victim did not report the incident immediately” shift focus onto the victim’s behaviour rather than the perpetrator’s actions.

    These details continue to affect broader legal narratives and public acceptance.

    Digital platforms are battlegrounds

    Recognizing these connections is crucial. As far-right movements gain ground by repackaging ideas about gender as nostalgic “truth” or “tradition,” we need to recognize that digital platforms are not neutral, nostalgic spaces.

    Rather, they are conversational battlegrounds where power is contested and jokes, tweets and speeches carry real political weight.

    In the fight for gender equity, the internet is not just a mirror that reflects multiple realities. It’s a tool built by the tech industry that was never intended to democratize communication, labour or social roles. Right now, that tool is being weaponized to signal and reassert patriarchal control.

  • MIL-OSI Global: How discussion becomes discord: Three avoidable steps on the path to polarization

    Source: The Conversation – Canada – By Emma Lei Jing, Assistant Professor, People and Organizations, Neoma Business School

    From tariffs and sovereignty to politics and conflict, there’s no shortage of controversial topics for us to grapple with. (Shutterstock)

    Many of us have become immersed in debates with family about a contentious political issue, or found ourselves on the other side of a political divide than our friends. In these contentious times, it can be all too easy for courteous debate to devolve into polarized discord.

    From tariffs and sovereignty to politics and conflict, there’s no shortage of controversial topics for us to grapple with. Canada just emerged from a divisive federal election, while in the United States, President Donald Trump signed a record 143 executive orders in his first 100 days in office, many of which touched on contentious topics.

    We recently conducted a study on the debate around harm reduction. Here in Canada, supervised consumption sites is one issue that has generated support and opposition from community members, healthcare and government agencies, police, addiction services and many others. And it has led to some becoming entrenched in polarized positions.

    Our research traced a path which led participants farther apart. Eventually, opposing camps became deeply divided and unwilling to engage with anyone holding different views, and it didn’t happen at random.

    What went wrong, and what set opposing groups on the path to discord?

    Signposts on the path to polarization

    Through an in-depth qualitative case study of addiction services in Alberta, our analysis showed that when the topic of harm reduction was first introduced, arguments were based mostly on evidence and reason.

    Harm reduction proponents pointed to the life-saving benefits of harm reduction and the inadequacies of traditional approaches, whereas opponents talked about the effectiveness of more traditional approaches.

    We saw genuine, and sometimes successful, efforts to persuade those who disagreed to change their minds.

    However, we identified a systematic progression from civil discourse to the formation of echo chambers. From that, we offer ways to steer conversations from developing into irreconcilable echo chambers.

    When emotions rise, people talk less about the pros and cons of an approach and more about what should be the right approach.

    Phase 1: Emotion deepens the divide

    In the case of the harm reduction debate, an opioid crisis shook Alberta. A steep increase in overdose deaths heightened urgency and intensity around the debate and ushered in more emotionally charged arguments. Before long, a moral component developed in the debate.

    When emotions rise, people talk less about the pros and cons of an approach and more about what should be the right approach.

    Disagreements escalate as the discussion veers away from logic and arguments become more morally and emotionally charged. This heightened a sense of being right, and the opposite view being wrong, provides fertile ground for polarization.

    This phase is where there is the greatest opportunity to change course. Be aware of the rising emotional energy. If the debate is getting heated, avoid framing arguments in terms of what’s right and wrong and stay focused on evidence and reason.

    Phase 2: Heightened hostility

    This is where things get personal.

    As emotional rhetoric takes hold, participants pull farther apart and animosity grows. They start characterizing people on either side of the debate as morally right or wrong.

    Just as we saw in phase one, a watershed event deepened the divide in Alberta. A newly elected provincial government took a distinctly different approach than the previous government, leaving advocates on one side feeling vindicated and their opponents shocked, dismayed and angry.

    In phase two, the issue itself takes a back seat, and participants started blaming their opponents for making matters worse. There is less dialogue about an approach being right or wrong, and more about the people involved being right or wrong.

    This is possibly the last chance to turn things around. At this point, we should be mindful about the importance of neutral and respectful language. One way to do this is by avoiding making things personal, such as blaming one another for a situation.

    Disagreements escalate as a discussion veers away from logic and arguments become more morally and emotionally charged.

    Phase 3: Disdain, disgust and self-isolation

    By now, logical arguments have been abandoned, replaced with intense expressions of disgust and disdain for opponents. No longer interested in persuading the other side, the focus shifts to solidifying a position as both sides withdraw from debate and only engage with like-minded people.

    In our study, this phase, like the previous phases, was brought on by a distinct event. A second provincial election ushered in an abrupt reversal in leadership and harm reduction policies. Any attempts to work together were abandoned and participants started entrenching themselves in self-constructed echo chambers.

    In this most devastating and possibly irreparable phase, we noted that the rhetoric wasn’t even about what was right or wrong anymore. It was more about expressing disgust toward one another, leaving no room for facts, evidence or even different opinions, firmly establishing two entrenched sides.

    Moral convictions and emotions play a critical role in escalating disagreements. The damage caused when civil arguments are subtly replaced with moral convictions and moral emotions can impact how we co-operate and interact with one another, even in our day-to-day conversations with families and friends.

    In the context of addiction services in Alberta, there has now been an extended period of “cooling down” where both sides are taking a wait-and-see approach. We suggest that this is creating a climate where an engaged discussion with fact-based arguments can again be possible.

    But even better would be a more proactive approach where participants of a debate recognize the warning signs and take actions early.

  • MIL-OSI Global: Alzheimer’s: bacteria that cause stomach ulcers may protect the brain, our new research indicates

    Source: The Conversation – UK – By Gefei Chen, Associate professor, Karolinska Institutet

    Every three seconds, someone in the world develops dementia. Alzheimer’s disease is the most common form of dementia, accounting for between 60% and 70% of all cases.

    Although scientists have made significant progress in understanding the disease, there’s still no cure. That’s partly because Alzheimer’s disease has multiple causes – many of which are still not fully understood.

    Two proteins which are widely believed to play central roles in Alzheimer’s disease are amyloid-beta and tau. Amyloid-beta forms sticky plaques on the outside of brain cells. This disrupts communication between neurons. Tau accumulate inside brain cells, where it twists into tangles. This ultimately leads to cell death. These plaques and tangles are the hallmark features of Alzheimer’s disease.

    This understanding, known as the amyloid hypothesis, has shaped research for decades and led to treatments that aim to clear amyloid from the brain. Monoclonal antibody drugs have been approved in recent years for this purpose.

    But they only work in the early stages of the disease. They do not reverse existing damage and may cause serious side-effects such as brain swelling and bleeding. Most importantly, they only target amyloid-beta, leaving tau untreated.

    But in a surprise twist, recent research published by my colleagues and me has found that a protein from Helicobacter pylori – a bacteria best known for causing stomach ulcers – can block the toxic buildup of both amyloid-beta and tau. This unexpected finding may point to a new strategy for the fight against Alzheimer’s disease.

    Our discovery began with a very different question. We were initially studying how H pylori interacts with other microbes. Some bacteria form protective communities called biofilms, which rely on amyloid assemblies (similar in structure to the plaques which form in the brain) as a structural scaffold. This led us to wonder: could H pylori influence bacterial biofilms by also interfering with amyloid assemblies in humans?

    We turned our attention to a well-known H pylori protein called CagA. While half of the protein is known to trigger harmful effects in human cells (referred to as the C-terminal region), the other half (the protein’s N-terminal region) may have protective properties. To our surprise, this N-terminal fragment, called CagAN, dramatically reduced the formation of both bacterial amyloids and biofilms in the bacterial species Escherichia coli and Pseudomonas.

    Encouraged by these results, we tested whether the same protein fragment could block the buildup of human amyloid-beta proteins. To do this, we incubated amyloid-beta molecules in the lab: some were treated with CagAN, while others were left as normal. We then tracked amyloid formation using a fluorescence reader and an electron microscope.

    The protein derived from H pylori blocked amyloid-beta plaques from forming.

    We found that treated samples had far less amyloid clump formation during the testing period. Even at very low concentrations, CagAN almost completely stopped amyloid-beta from forming amyloid aggregates.

    To understand how CagAN worked, we used nuclear magnetic resonance (which allows us to look at how molecules interact with each other) to examine how the protein interacts with amyloid-beta. We also used computer modelling to investigate possible mechanisms. Remarkably, CagAN also blocked tau aggregation – suggesting it acts on multiple toxic proteins involved in Alzheimer’s disease.

    Blocking the disease

    Our study has shown us that a fragment from the Helicobacter pylori protein can effectively block the buildup of the two proteins that are implicated in Alzheimer’s disease. This suggests that bacterial proteins – or drugs modelled after them – could someday block the earliest signs of Alzheimer’s.

    What’s more, the benefits may extend beyond Alzheimer’s disease.

    In additional experiments, the same bacterial fragment blocked the aggregation of IAPP (a protein involved in type 2 diabetes) and alpha-synuclein (linked to Parkinson’s disease). All of these conditions are driven by the accumulation of toxic amyloid aggregates.

    That a single bacterial fragment could interfere with so many proteins suggests exciting therapeutic potential. Though these conditions affect different parts of the body, they may be linked through cross-talk between amyloid proteins – a shared mechanism that CagAN could help disrupt.

    Of course, it’s important to be clear: this research is still at an early stage. All of our experiments were conducted in lab settings, not yet in animals or humans. Still, the findings open a new path.

    Our study also uncovered the underlying mechanisms for how CagAN blocked the amyloid-beta and tau from forming amyloid aggregates. One of the ways in which CagAN did this was by preventing the proteins from coming together to form clumps. They also prevented small, premature amyloid aggregates from forming as well. In the future, we will continue the detailed mechanism study and evaluate the effects in animal models.

    These results also prompt a question: could H pylori, long seen only as harmful, also have a protective side? Some studies have hinted at a connection between H pylori infection and Alzheimer’s disease, though the relationship remains unclear. Our discovery adds a new layer to this discussion, suggesting that part of H pylori may actually interfere with the molecular events that lead to Alzheimer’s disease.

    That means in the future, we may need to take a more precise and personalised approach. Instead of aiming to eliminate H pylori completely with antibiotics, it might be more important to understand, in different biological contexts, which parts of the bacterium are harmful, and which might actually be beneficial.

    As medicine continues to move toward greater precision, the goal may no longer be to wipe out every microbe, but to understand how some of them might work with us rather than against us.

  • MIL-OSI Global: Nineteen Eighty-Four might have been inspired by George Orwell’s fear of drowning

    Source: The Conversation – UK – By Nathan Waddell, Associate Professor in Twentieth-Century Literature, University of Birmingham

    George Orwell had a traumatic relationship with the sea. In August 1947, while he was writing Nineteen Eighty-Four (1949) on the island of Jura in the Scottish Hebrides, he went on a fishing trip with his young son, nephew and niece.

    Having misread the tidal schedules, on the way back Orwell mistakenly piloted the boat into rough swells. He was pulled into the fringe of the Corryvreckan whirlpool off the coasts of Jura and Scarba. The boat capsized and Orwell and his relatives were thrown overboard.

    It was a close call – a fact recorded with characteristic detachment by Orwell in his diary that same evening: “On return journey today ran into the whirlpool & were all nearly drowned.” Though he seems to have taken the experience in his stride, this may have been a trauma response: detachment ensures the ability to persist after a near-death experience.

    We don’t know for sure if Nineteen Eighty-Four was influenced by the Corryvreckan incident. But it’s clear that the novel was written by a man fixated on water’s terrifying power.

    This article is part of Rethinking the Classics. The stories in this series offer insightful new ways to think about and interpret classic books and artworks. This is the canon – with a twist.

    Nineteen Eighty-Four isn’t typically associated with fear of death by water. Yet it’s filled with references to sinking ships, drowning people and the dread of oceanic engulfment. Fear of drowning is a torment that social dissidents might face in Room 101, the torture chamber to which all revolutionaries are sent in the appropriately named totalitarian state of Oceania.

    An early sequence in the novel describes a helicopter attack on a ship full of refugees, who are bombed as they fall into the sea. The novel’s protagonist, Winston Smith, has a recurring nightmare in which he dreams of his long-lost mother and sister trapped “in the saloon of a sinking ship, looking up at him through the darkening water”.

    George Orwell in 1943.
    National Union of Journalists

    The sight of them “drowning deeper every minute” takes Winston back to a culminating moment in his childhood when he stole chocolate from his mother’s hand, possibly condemning his sister to starvation. These watery graves imply that Winston is drowning in guilt.

    The “wateriness” of Nineteen Eighty-Four may have another interesting historical source. In his essay My Country Right or Left (1940), Orwell recalls that when he had just become a teenager he read about the “atrocity stories” of the first world war.

    Orwell states in this same essay that “nothing in the whole war moved [him] so deeply as the loss of the Titanic had done a few years earlier”, in 1912. What upset Orwell most about the Titanic disaster was that in its final moments it “suddenly up-ended and sank bow foremost, so that the people clinging to the stern were lifted no less than 300 feet into the air before they plunged into the abyss”.

    Sinking ships and dying civilisations

    Orwell never forgot this image. Something similar to it appears in his novel Keep the Aspidistra Flying (1936) where the idea of a sinking passenger liner evokes the collapse of modern civilisation, just as the Titanic disaster evoked the end of Edwardian industrial confidence two decades beforehand.

    The Titanic disaster had a profound impact on Orwell.
    Wiki Commons

    References to sinking ships and drowning people appear at key moments in many other works by Orwell, too. But did the full impact of the Titanic surface in Nineteen Eighty-Four?

    Sinking ships were part of Orwell’s descriptive toolkit. In Nineteen Eighty-Four, a novel driven by memories of unsympathetic water, they convey nightmares. Filled with references to water and liquidity, it’s one of the most aqueous novels Orwell produced, relying for many of its most shocking episodes on imagery of desperate people drowning or facing imminent death on sinking sea craft.

    The thought of trapped passengers descending into the depths survives in Winston’s traumatic memories of his mother and sister, who, in the logic of his dreams, are alive inside a sinking ship’s saloon.

    There’s no way to prove that the Nineteen Eighty-Four is “about” the Titanic disaster, but in the novel, and indeed in Orwell’s wider body of work, there are too many tantalising hints to let the matter rest.

    Thinking about fear of death by water takes us into Orwell’s terrors just as it takes us into Winston’s, allowing readers to see the frightened boy inside the adult man and, indeed, inside the author who dreamed up one of the 20th century’s most famous nightmares.

    Beyond the canon

    As part of the Rethinking the Classics series, we’re asking our experts to recommend a book or artwork that tackles similar themes to the canonical work in question, but isn’t (yet) considered a classic itself. Here is Nathan Waddell’s suggestion:

    As soon as the news broke of the Titanic’s sinking, literary works of all shapes and sizes started to appear in tribute to the disaster and its victims. As the century went on, and as research into the tragedy developed (particularly after the ships wreckage was discovered in 1985), more nuanced literary responses to the sinking became possible.

    One such response is Beryl Bainbridge’s Whitbread-prize-winning novel Every Man for Himself (1996). It reimagines the disaster from the first-person perspective of an imaginary character, Morgan, the fictional nephew of the historically real financier J. P. Morgan (who was due to sail on the Titanic but changed plans before it sailed).

  • MIL-OSI Global: Why Israel-Iran tensions might not raise prices at the pump as much as feared (for now)

    The unexpected attack by Israel on Iran, a major oil-producing nation, may undermine anaemic global economic growth and hinder central banks’ ability to cope in an already uncertain market.

    Iran exports up to 2 million barrels of oil and refined petroleum products per day (million barrels per day – mbd). Due to long-standing sanctions, most of this oil is sold to China at discounted prices.

    Normally, a sudden loss of the Iranian exports (equivalent to around 2% of global oil supply) would trigger panic. But Opec (the Organisation of the Petroleum Exporting Countries) is in the process of reversing the production cuts imposed early in the COVID pandemic (and subsequently). This leaves the organisation with an unusually large spare capacity of at least four million barrels per day, most of which is held by Saudi Arabia (up to 3.5 million) and the UAE (about one million).

    On top of that, the International Energy Agency (IEA) holds more than 1.2 billion barrels of emergency reserves across OECD countries, ready to be deployed if needed. China, too, has significant reserves, though the line between its commercial and strategic stocks is less clear.

    Additionally, some 40 million barrels of Iranian oil are stranded aboard anchored ships near China, unsold due to declining industrial demand and electric vehicles hitting petrol consumption. In May, China’s refinery throughput fell 1.8% year-on-year, with no signs of a swift rebound. What’s more, the IEA is expecting global oil production to exceed 1.8 mbd, compared to its earlier projection of only 0.72 mbd, leaving a massive surplus of supply over demand.

    China has proven to be an opportunistic buyer. It did not buy the excess Iranian oil supplies at US$65 (£48) a barrel earlier this year, and whether it buys at US$75 (at the time of writing) or higher, may be a signal of how seriously it views the Middle East tensions. Meanwhile, other Asian importers have been quick to secure prompt shipments from west Africa, and have eyes on US supplies as well.

    Thanks to this surplus capacity and stagnant demand, the oil market’s reaction has been more muted than many feared. Prices briefly spiked by US$10 but have since eased. It appears that the market is assessing whether the hostilities will escalate. If so, the impact on energy prices and inflation could be more significant.

    A conflict of convenience

    It remains somewhat unclear why Israeli prime minister Benjamin Netanyahu chose this moment to strike Iran, especially in the middle of peace negotiations between Iran and the United States. In a recent interview, former Israeli leader Ehud Barak admitted that even a full-scale attack would only delay Iran’s nuclear ambitions by weeks or months at best, with US support.

    Diplomacy, then, may remain the more effective route. This was the rationale behind the Iran nuclear deal brokered under US president Barack Obama, a deal later dismantled by Trump under pressure from Netanyahu.

    So, Netanyahu’s endgame might be political survival and diverting attention from the humanitarian catastrophe in Gaza.

    If Iran feels sufficiently cornered, it may retaliate by shutting down the Strait of Hormuz – a strategic chokepoint through which up to 20 million barrels of oil pass daily. A lot of that oil can be diverted through alternative supply routes such as a large (6 mbd) Saudi East-West pipeline leading to the Red Sea. There is also the UAE pipeline, which avoids the Strait of Hormuz and leads to the port of Fujairah, in the Gulf of Oman.

    Iran could close off the Strait of Hormuz, causing widespread disruption.

    Nevertheless, the increased risk and higher shipping costs would certainly result in much higher prices at the pump. The cost of insurance for ships travelling through the Strait of Hormuz have jumped 60% since the start of the conflict. That, combined with the broader economic fallout, could have global repercussions.

    The World Bank recently downgraded its global growth forecast to 2.3% for 2025 – nearly half a percentage point below previous estimates. While a worldwide recession is not yet predicted, the bank warned that growth this decade could be the slowest since the 1960s.

    Among the leading culprits is Trump’s tariff policy, which has strained global trade, reduced efficiency and effectively imposed a tax on consumers both in the US and elsewhere. The fear of inflation has led to rising long-term bond yields.

    Expectations of higher inflation and high bond yields, in turn, constrain central banks from stimulating the economy by cutting interest rates. This is a key tool used by the US Federal Reserve to influence the cost of borrowing throughout the US economy and thus attempt to stimulate economic activity.

    And in spite of the recent US-UK trade agreement, the deal includes a 10% tariff on imports from the UK – with steel still at 25%.

    UK economic growth had already slipped into negative territory before the conflict began. Now, with the added strain of geopolitical instability, households are bracing for higher petrol prices at the pump, sluggish wage growth and rising unemployment. The conflict in the Middle East may not have sparked a global oil crisis yet, but it certainly won’t improve anyone’s cost of living.

  • MIL-OSI Global: England is expanding free school meals – here’s what could happen if they were given to all children

    Source: The Conversation – UK – By Sanghamitra Bandyopadhyay, Professor of Development Economics , Queen Mary University of London

    The UK government has announced an extension of free school meals in England to all children whose parents receive universal credit, in order to address child hunger and poverty.

    The government claims that half a million more pupils will now have access to school lunches for free. The total number of children registered for free school meals in England is currently about 2.2 million, or about 26% of the total school population. In addition, all children in infant school, aged between four and seven, are entitled to receive a hot lunch at school.

    But given the high rates of child poverty in the UK, and the value a decent meal provides, there is evidence that free school meals for all children could provide significant benefits in England.

    The provision in Scotland and Wales is more generous: free school meals for children from primary one to five in Scotland (ages four to ten) and for all children in primary school in Wales. But other countries make provision for all children, in both primary and secondary education, to receive meals at school.

    Child poverty in the UK continues to be historically high. In 2023-24, 3.4 million children – 23% of all children in the UK – were in relative income poverty. Incidence of child poverty is particularly acute in cities.

    In the UK, the COVID-19 pandemic and Brexit resulted in a rise in unemployment. This in turn led to widespread instances of extreme poverty and child hunger. The lack of active policies in the UK to address child hunger, malnourishment and increasing childhood obesity has been widely criticised by the British Medical Association.

    The UK’s experience of high levels of child poverty is in stark contrast with most other high-income countries. The UK ranked 37th out of 39 by child income poverty, ahead only of Turkey and Colombia, in 2023. In comparison, the UK’s adult poverty rate is close to the OECD average, ranking 23rd out of 39 high-income countries. This implies that child poverty can be high even if adult poverty levels are relatively low.

    Global policy choices

    Providing nutritious free school meals is a fundamental cornerstone of government policy to ensure child welfare. It’s used as a poverty alleviation measure all over the world. Almost half of the world’s school meals are free, feeding 418 million children.

    Many of these programmes are based in developing countries. The world’s largest free school meal programme runs in India: the “mid-day meal scheme” feeds 125 million children aged six to 14 and costs the equivalent of £2 billion each year. Similar successful programmes are run in Brazil and some African countries, with another having recently been launched in Indonesia.

    But schemes in Finland and Sweden also cover almost all school children.

    There is a growing body of global evidence on the wider beneficial effects of free school meals on child poverty. Free school meals in India have resulted in higher cognitive outcomes. They have increased school enrolment and school attendance, and thus educational outcomes.

    They have also been found to have an intergenerational effect. In India, fewer shorter children were born to women who had benefited from the country’s school food programme.

    Nutritionally balanced school meals have proven health benefits.
    Pixel-Shot/Shutterstock

    Nutritionally balanced children’s school meals are also associated with lower incidence of obesity. Studies in the US and UK, for example, have shown universal provision is linked to lower obesity rates.

    Research into the Swedish scheme has found that children who have free school meals with prescribed nutritional standards not only have higher educational attainment and better health outcomes in adulthood, but also higher incomes. Children from families in the lowest income quartile in Sweden who received free school meals for nine years increased their lifetime income by 6%.

    Other tangible economic benefits include significant reductions in potential healthcare costs as a result of malnutrition and non-communicable diseases. A 2025 European Union report estimates the return from investment in school meal programmes is at least sevenfold, up to a possible €34 for every €1 spent.

    While there is rich scientific and economic evidence that universal free school meals are immensely beneficial, a child’s access to nutrition and government support to obtain nourishment is also a fundamental human right. The School Meals Coalition is an international consortium of 108 countries to achieve free school meals for all by 2030. The UK is one of the few advanced countries not signed up to it.

  • MIL-OSI Global: The UK’s warm homes plan has been saved – here’s how Labour can learn from a decade of failed insulation schemes

    Source: The Conversation – UK – By Madeleine Pauker, PhD Candidate, Science Policy Research Unit, University of Sussex

    The UK government confirmed in its June 2025 spending review that it will honour its manifesto pledge and not cut the £13.2 billion warm homes plan, as had been speculated. The money will be spent over the next four years, marking a significant increase on funding for energy-related home upgrades compared to that offered by the previous government.

    The plan encompasses several programmes for cutting energy bills and reducing carbon emissions by making homes easier to heat and replacing gas boilers and other fossil fuel heating systems. Low-income homeowners and renters will receive grants for “retrofit” upgrades such as insulation, solar panels and heat pumps through schemes delivered by energy companies and councils.

    All homeowners can benefit from the boiler upgrade scheme, which offers £7,500 towards the cost of a heat pump, and those living in the least energy efficient homes can get free loft or cavity wall insulation. Councils and housing associations will also receive funding to make upgrades to their properties.

    The British government has provided some form of financial support for insulation and other energy efficiency measures since the 1970s. Millions of homes were insulated over the 2000s, but over the last decade support has been cut and the number of households taking up grants has collapsed. Programmes have also not been designed to provide comprehensive, high-quality retrofits.

    Over the next few years, the warm homes plan will significantly increase the amount of funding available for retrofitting homes. This is an opportunity to reshape the UK’s strategy for fixing its cold, leaky housing stock, reduce reliance on gas heating and lower household energy bills.

    How support for retrofitting has evolved

    For the last 30 years, energy companies have been required to provide insulation and other energy efficiency measures to households. These programmes are funded by levies on energy bills rather than public spending.

    From 1994 to 2015 any homeowner, landlord, or renter could receive energy efficiency measures such as insulation from energy companies. Additional publicly funded schemes sought to eliminate fuel poverty and targeted low-income households. This approach proved broadly successful throughout the 2000s and early 2010s. At its peak in 2008-11, one in five UK households received insulation, more efficient boilers or another form of support.

    However, these schemes were never designed to provide the comprehensive retrofits that modern climate targets demand. Ultimately, they failed to take a whole-house approach that could address multiple energy-efficiency issues at once.

    A pivotal moment came in 2015 when the Conservative-Liberal Democrat coalition government removed universal eligibility from supplier-led schemes and shaved £30 off annual household bills. Low-income and vulnerable households, which had already constituted a priority group under energy company-led schemes, became the only demographic eligible for support. Following this decision – plus other modifications to the programmes – the number of insulation measures installed each year fell by about 70%.

    In 2023, the Conservative government of Rishi Sunak introduced the Great British insulation scheme which offers free cavity wall or loft insulation to homes registered given an efficiency rating of D or below (ratings run from A for the most efficient to G for the least). The universal boiler upgrade scheme was also introduced.

    Meanwhile, the energy company obligation, which provides a greater range of measures, including several types of insulation, heat pumps and solar panels, remains restricted to low-income and vulnerable households.

    However, due to complex eligibility requirements, low public awareness and a lack of trust, among other reasons, most of the financial support available is not reaching households and the number of homes receiving upgrades has not recovered.

    Heat pumps can get homes off gas, but installations trail boiler fittings.

    The problems with current schemes

    While reinstating universal support is positive, the boiler upgrade scheme only covers about half the cost of installing a heat pump, making it a subsidy for wealthier households that can afford to foot the rest of the bill.

    Energy bill levies, which fund the energy company obligation, disproportionately burden poorer households, which spend a higher proportion of income on energy. At the same time, while everyone continues to pay for the programme via their energy bills, restrictive eligibility requirements leave most households who cannot cover retrofit costs independently without support.

    The scheme also incentivises companies and their subcontractors to meet the scheme’s carbon reduction requirements at the lowest possible cost. This discourages whole-house retrofits, more complex insulation measures, repairs prior to retrofit (such as removing damp and mould or repairing roofs) and work in certain types of homes.

    Resulting insulation failures have damaged public confidence in retrofit programmes. These problems highlight the mismatch between a market-driven approach and the comprehensive changes necessary to make homes healthier to live in and cheaper to heat, as well as meet climate targets and restore public trust.

    The case for replacing supplier-led schemes with public alternatives remains compelling, despite the government’s supposed fiscal constraints. Rather than relying on energy companies and their subcontractors for complex home interventions, councils could be empowered to guide households through the retrofit process and combine homes in area-based schemes.

    The warm homes plan includes funding for councils to retrofit low-income households, including those earning less than £36,000, receiving means-tested benefits, or living in certain postcodes. But the scale of the programme is much smaller than the energy company obligation, although investment will increase over the next few years.

    This is still a narrow approach to improve the country’s housing that focuses on low-income households, though most middle-income households cannot afford the cost of a retrofit either. The budget for other home improvements remains minimal – homes in poor condition are likely to be missed.

    Details of how most of the warm homes plan funding will be spent is due to be revealed in autumn 2025. There is still time for the government to choose a more progressive approach.

    An alternative would be to expand grant-funded upgrades for low-income homeowners and offer low-interest, long-term, property-linked loans for middle-income households. This could be designed to cover whole-house retrofits, encompassing insulation, ventilation, heat pumps, solar panels and other measures, as well as repairs.

    There are also emerging plans from consultancies working with local governments to develop area-based retrofit programmes that blend public and private investment, aiming to attract investment from pension funds to shift the cost of retrofitting away from households.

    However, it remains unclear whether such models will offer sufficiently competitive returns and low enough risk to appeal to institutional investors – and the UK cannot afford to wait for private capital to materialise when nationwide retrofitting is urgently needed.

  • MIL-OSI Global: Wandering uteruses and far-reaching tubes: the surprising mobility of the female reproductive tract

    Source: The Conversation – UK – By Michelle Spear, Professor of Anatomy, University of Bristol

    The ancient wandering womb theory suggested that many ailments in women were caused by the uterus becoming dislodged and roaming the body in search of moisture.

    According to these theories, the uterus could roam freely around the body, pressing on the liver or lungs and causing symptoms such as breathlessness, fainting and emotional distress – what was later termed “hysteria”, from the Greek hystera (uterus).

    Treatments included fumigating the lower body with sweet-smelling herbs to entice the uterus back downward, exposing the nose to pungent odours to drive it away from the chest and adding weights to the abdomen to prevent the uterus from rising. Marriage and pregnancy were often prescribed as cures, under the belief that a busy uterus was a happy, well-behaved one.

    In the 18th century, advances in anatomy and dissection began to disprove the notion that the uterus could physically roam. However, the legacy of the wandering womb lived on well into the 20th century in the diagnosis of “female hysteria”, an unevidenced catch-all for a multitude of symptoms.

    While the uterus doesn’t float around like a balloon in the chest cavity, it does change position. And this matters. Mobility is essential for fertility, menstruation, pregnancy and pelvic health.

    How much does the uterus move?

    The uterus sits between the bladder and the rectum, suspended by a series of ligaments. These don’t hold it immobile – rather, they allow it to rock and tilt.

    Its position can be anteverted (tilted forward over the bladder), retroverted (angled back toward the rectum and spine), or somewhere in between. These variations are entirely normal and often vary.

    That position matters. The uterine angle can affect where menstrual pain is experienced. For those with a retroverted uterus, discomfort may radiate into the lower back. For others, cramping is felt more in the lower abdomen.

    A forward-tilted uterus may press more directly on the bladder, increasing the urge to urinate, especially in early pregnancy. Conversely, a backward tilt might impinge on the rectum, contributing to constipation or bloating.

    During sexual arousal, the uterus “tents” – lifting slightly and lengthening the vaginal canal. During labour, it contracts powerfully and rhythmically, drawing the cervix upwards and helping to expel the foetus.

    Even the cervix – the narrow opening at the base of the uterus – is not fixed in place. Its height, texture and openness vary across the menstrual cycle in response to hormonal cues. During ovulation, it rises and softens to allow sperm entry. Before menstruation, it lowers and firms up again.

    The uterine tubes: searching, not wandering

    Perhaps the most surprising anatomical revelation is that a uterine (fallopian) tube on one side of the body can capture an egg released from the opposite ovary. If there’s a true seeker in the reproductive tract, it’s the uterine tube.

    Each month, at ovulation, the fimbriae – finger-like projections at the end of the tube – sweep across the surface of the ovary, coaxing the released egg into the tube’s entrance. The tube isn’t anchored directly to the ovary. Instead, it finds it. Like a sea anemone in slow motion, it explores, flexes and moves.

    Once caught, cilia – tiny hair-like structures that line the inner surface of the tube – work in concert with muscular contractions that move the egg towards the uterus. This choreography is vital but also explains the risk of ectopic pregnancy.

    If a fertilised egg implants in the tube instead of travelling to the uterus, it can pose a serious medical emergency. Ironically, it’s the very adaptability and reach of the tube that makes it vulnerable.

    The ovaries are also slightly mobile, suspended by ligaments that allow for some degree of movement within the pelvic cavity. This becomes especially apparent after hysterectomy when the removal of the uterus can cause the ovaries to “drift”, sometimes complicating imaging or surgical planning.

    While their movement is more limited than that of the uterus or tubes, it still plays a role in pelvic dynamics. In rare cases, it can result in ovarian torsion, a painful twisting of the organ that requires emergency care.

    While mobility is normal, excessive movement or weakened support can cause problems. Uterine prolapse – when the uterus descends into or beyond the vaginal canal – can result from weakened pelvic floor muscles, often after multiple childbirths or due to age-related changes. It’s a mechanical failure, not a moral one. Sadly, though, history hasn’t always treated it that way.

    Similarly, adhesions from endometriosis or previous surgeries can limit natural mobility, causing severe pain as organs that should glide against one another become tethered and inflamed.

    While the uterus does indeed move, it does so within anatomical boundaries and under the influence of ligaments and hormones – not whim. The enduring myth of the wandering womb reflected broader anxieties about the female body: that it was unpredictable, unruly and in need of control. Today, with the benefit of imaging, dissection and anatomical research, we can replace that myth with a deeper understanding of purposeful mobility.

  • MIL-OSI Global: Blinding lights: the hidden science behind gambling’s glow

    Source: The Conversation – UK – By Glen Dighton, Research Officer at the Centre for Military Gambling Research (MilGAM), Swansea University

    MMPhoto21/Shutterstuck

    There’s a reason casinos rarely have windows or clocks, they’re engineered to make you lose track of time. But what if it’s not just time you’re losing? New research suggests that the lighting used in gambling environments could be quietly altering how we make decisions, making us more prone to take risks.

    The colour of the lights surrounding us can do more than just set the mood. It can shape our behaviour.

    The new study from researchers at Flinders University in Australia found that blue-enriched lighting (the same cold, bright hue used in many modern LED lights and digital screens) can reduce a gambler’s sensitivity to losses. In a controlled experiment, participants exposed to this kind of light took riskier bets and responded less emotionally to losing.

    The researchers believe this change in decision-making is rooted in our biology. The human body is sensitive to different wavelengths of light, not just for vision but also for regulating our internal clocks and emotional states. Blue light in particular has been shown to suppress melatonin production, a hormone which signals to the body it’s time to prepare for sleep.

    Research has also shown blue light can increase alertness and influence brain areas tied to reward and motivation by stimulating the neural circuits involved in anticipation and decision-making. In the case of gambling, this heightened arousal might dampen our natural aversion to loss, even when the odds are stacked against us.

    Light can influence us in many other surprising ways. Studies have shown that cooler, blue-toned lighting can enhance cognitive performance and alertness during the day, which is why it’s often used in offices and classrooms. Warmer lighting is more relaxing and is typically recommended by sleep scientists and health professionals for evenings to promote better sleep.

    Blue light can make you less sensitive to losing.

    Retailers, too, have long exploited the psychological effects of lighting, using bright, targeted lighting – often in the form of spotlighting or high-intensity LEDs – to draw attention to products.

    The colour and intensity of lighting can also affect consumers’ perception of value and attractiveness. This encourages spending by increasing visual salience, making a product stand out more and grab your attention, and creating a more engaging sensory experience.

    Specific colours of light seem to have an array of effects in different environments. Red lighting may have effects which increase appetite. This is possibly because it stimulates the sympathetic nervous system, which is associated with arousal and physiological readiness. Meanwhile studies suggest green light may reduce pain and light sensitivity for migraine sufferers.

    But lighting is only one half of the sensory equation in casinos. Sound design plays a major role in immersive gambling environments. Upbeat music can make people less risk-averse by speeding up decision-making and creating a sense of urgency.

    Jingles and celebratory sounds serve as auditory rewards, reinforcing positive feelings even in the absence of a financial win. When players lose, slot machines often produce celebratory sounds and flashing lights, creating what researchers call a “loss disguised as a win”. This sensory mismatch tricks the brain into thinking it’s succeeding, distorting our ability to assess risk or stop playing.

    In gambling environments, red light combined with casino‑style sounds has been shown to eliminate the usual cognitive slowdown after losses during decision-making tasks, leading players to make faster choices without the normal pause for reflection.

    A 2018 study showed that flashing animations and vivid colours can increase arousal and attention, making gambling more stimulating and immersive. This, in turn, delays self-regulation and increases time spent gambling. In effect, your surroundings are constantly nudging you to stay, to play, and to believe the next win is just around the corner.

    As gambling moves increasingly online, these principles are being translated to digital platforms. Online slot games often use flashing animations, vivid colours, and background music that mimic the ambience of a physical casino. The blue light emitted from screens can be just as stimulating – especially late at night – potentially exacerbating the effects seen in the Flinders University study.

    Online and mobile gambling uses these techniques to keep you playing too.
    Marko Aliaksandr/Shutterstock

    If subtle changes to lighting can lead to riskier decisions, then regulating these features might help promote less harmful gambling behaviour. For instance, encouraging warmer lighting in gambling venues or digital settings could help prevent excessive play.

    The lights and sounds that surround us in these environments aren’t just decoration. They’re carefully designed to heighten arousal, dull sensitivity to losses, and encourage riskier decisions.

    Our responses to colour, brightness and sound happen at a subconscious level, meaning even informed players can still be swayed by them. Reducing your device’s screen brightness, using blue light filters at night, or turning off in-game sounds can help counteract some of these psychological effects for online gambling.

    But meaningful change will probably require policy intervention that treats environmental design not as a neutral backdrop, but as a powerful behavioural influence – one that should be shaped with responsibility to the wellbeing of the consumer, not just profit, in mind.

  • MIL-OSI Global: Tracing the Drax family’s millions – a story of British landed gentry, slavery and sugar plantations

    Source: The Conversation – UK – By Paul Lashmar, Reader in Journalism, City St George’s, University of London

    ‘Planting the sugar-cane’: vast fortunes were made from the trades in both sugar and human slaves in the Americas. Schomburg Center for Research in Black Culture, Photographs and Prints Division, The New York Public Library

    Rich British aristocratic families with a legacy of owning colonial slave plantations are often accused by campaigners that their wealth solely originates from these plantations. One frequent target of this criticism has been the Drax family of Dorset, which is headed by Richard Grosvenor Plunkett-Ernle-Erle-Drax, who was the Conservative MP for South Dorset until July 2024.

    Historian Alan Lester of the University of Sussex has noted of Drax (as he is commonly known): “Much of his fortune is inherited, coming down the family line from ownership of the Drax sugar plantations and the 30,000 enslaved people who worked them as Drax property for 180 years before emancipation in Barbados.”

    Recently, I have researched and written a book on the Drax family’s history and involvement in the slave trade in the Caribbean, Drax of Drax Hall, that gives fresh insights into the level of wealth they derived from the sugar trade and the trade in African slaves who worked their plantations – as well as the family’s other income sources.

    I searched the archives in the UK and Caribbean for evidence of their revenue streams until Britain’s 1834 abolition of slavery in the colonies. I estimate that the family today are worth more than £150 million from their land and property in Dorset and Yorkshire.

    Over a period of two centuries until 1834, eight generations of Drax ancestors owned and worked hundreds of enslaved African captives at any one time. The latest beneficiary of primogeniture – the legal concept that recognises the first-born child as heir to a familiy’s fortune – Richard Drax inherited the family’s still-operating 621-acre Drax Hall plantation in Barbados in 2021.

    Drax, 67, has said: “I am keenly aware of the slave trade in the West Indies, and the role my very distant ancestor played in it is deeply, deeply regrettable. But no one can be held responsible today for what happened many hundreds of years ago. This is a part of the nation’s history, from which we must all learn.”

    My research reveals the sources of his family’s wealth are more complex than the critics’ claims that it all derives from the slave-worked plantations.

    Like most British landed gentry, much of the Drax family income has come as extensive landlords of their British estates which, in 1883, exceeded 23,000 acres across various counties. Today, it includes nearly 16,000 acres in Dorset and 2,520 acres in the Yorkshire Dales.

    However, my research also shows the Drax family made more money from slavery than was previously thought, when taking into account the way revenues from their plantations were channelled into the family’s British estates over the two centuries of slavery.

    Drax Hall plantation in Barbados

    The Drax Hall plantation in the Barbados parish of Saint George has been described by Barbadian historian Sir Hilary Beckles, chair of the Caribbean Community reparations commission, as a “killing field” where as many as 30,000 slaves died in brutal conditions. Despite pressure from reparation campaigners in the Caribbean, Britain and elsewhere, Richard Drax has declined to make a formal public apology or gesture of recompense in the Caribbean for the years of slavery.

    As the prime minister of Barbados, Mia Mottley, explained in April 2024, despite the efforts of her government Drax has yet to agree to a settlement, pay reparations or contribute all or part of his family’s Drax Hall plantation to provide affordable housing or become a memorial to those who worked and died in colonial enslavement on the island.

    Some other British landed families whose ancestors owned slave plantations in the Caribbean, including the Trevelyans (who owned six slave plantations in Grenada) and the Gladstones (British prime minister William Gladstone’s father owned plantations in Guyana), have made formal apologies and reparations. And while some families have kept the terms of these reparations private, longtime BBC reporter Laura Trevelyan made a US$100,000 (£73,000) donation to a Caribbean development fund.

    The largest family estate

    Four thousand miles from Barbados, Richard Drax lives in Charborough House, a historic 17th-century mansion in Dorset. He oversees the 23.5-square mile estate, the largest family estate in Dorset with over 120 properties, many of which are rented out.

    Charborough was acquired by Drax’s ancestor Walter Erle by marriage in 1549. The family has gradually increased the estate over the centuries. Historically, their income comes from renting land to tenant farmers and cottages to agricultural workers. This, I identified, is where the bulk of their income has come from.

    However, profits from sugar produced by slavery also poured into the family coffers over 200 years. Richard Drax’s remote ancestor James Drax (1609-1661) was one of the first settler group to arrive in the then-uninhabited island of Barbados in 1627. In his introduction to my book, TV historian David Olusoga writes that the Drax family were key players – arguably the key players – in the origin story of British slavery:

    The Drax Hall plantation, the first estate on which a crop of sugar was commercially grown and processed by any English planter, became one of the laboratories in which early English slavery was developed and finessed.

    Built around 1650, the Jacobean plantation house is thought to be the one of the three oldest extant residential buildings in the Americas. From the 17th into the 18th century, the Draxes created and owned the largest acreage in Barbados with the Drax Hall and and Mount plantations – plus a 3,000-acre estate, also called Drax Hall, in Jamaica. The family became enormously wealthy: James Drax was said by a visitor to Drax Hall in the 1640s to “live like a prince”, putting on lavish dinners for friends and guests.

    In addition to owning slaves, James Drax shipped African captives to Barbados as a key part of the trade in slaves. Knighted by both Oliver Cromwell and Charles I, by 1660 he was a director and investor in the English East India Company which, in part, traded and exploited enslaved people.

    In her 1930 study, American historian Elizabeth Donnan presented evidence that the Draxes of the 17th century operated “off the books” – buying enslaved people from, and selling them to, “interloper” ships that circumvented the Royal African Company’s monopoly of slave trading to the colonies.

    The Drax family married into the Erle family in 1719, combining three fortunes: that of the Erles of Charborough, the Draxes of Yorkshire, Barbados and Jamaica, and the landed-gentry Ernles of Wiltshire.

    Despite being deeply involved in the South Sea Bubble scandal, the Drax family flourished. The slave registers in the National Archives show that between 1825 and 1834, the Drax Hall plantation in Barbados produced an average of 163 tonnes of sugar and 4,845 gallons of rum per year. This gave the family an average annual net profit of £3,591 – equivalent to about £600,000 now. Today, the plantation still produces 700 tonnes of sugar a year, earning the family something in the region of £250,000.

    Pressure for reparations

    In recent years, the value of Drax Hall’s land in Barbados has greatly increased as it is sought after for housing, and could now be worth as much as Bds$150,000 (£60,000) per acre. At the same time, pressure for reparations is growing. In 2023, the African Union threw its weight behind the Caribbean reparations campaign.

    David Comissiong, deputy chairman of the Barbados reparations task force, has said: “Other families are involved, though not as prominently as the Draxes. This reparations journey has begun.”

    Yet to date, the only reparations paid in the story of the Drax family’s involvement in the slave trade were to the family itself. In 1837, Jane-Frances Erle-Drax, the heiress of Charborough, received £4,293 12s 6d (worth more than £614,000 today) in reparations for freeing 189 slaves from Drax Hall plantation after the abolition of slavery in the colonies.

    In the course of researching and writing my book, I approached Richard Drax both directly and through his lawyers and put the claims made here to him. He had no comment to add.

  • MIL-OSI Global: Why your doctor may not have given you the best advice for your lower back pain

    Source: The Conversation – UK – By Martin Underwood, Chair Professor, Primary Care Research, University of Warwick

    Treating lower back pain is enormously expensive. In the UK it’s estimated to cost the NHS around £3.2 billion a year. So, ensuring patients get the right treatment is critical.

    However, the guidance issued by the UK’s National Institute for Health and Care Excellence (Nice) on how to treat lower back pain was last updated in 2020, meaning many patients may be getting out-of-date advice from their healthcare practitioner.

    Fortunately, most people with lower back pain recover quickly without treatment. But a minority don’t, and they can go on to develop long-term disability.

    People with lower back pain usually see their GP first. The GP may refer the patient to a physiotherapist, or, in some parts of the UK, patients can refer themselves to one.

    However, Nice recommends using a short questionnaire to identify those least likely to recover, so they can be offered more intensive treatment. Those most likely to recover get an initial assessment and advice only.

    This approach was supported by a UK study which found a small benefit compared to offering everyone standard physiotherapy care. But later studies have not confirmed that result. It may not matter if care is targeted at those at highest risk or not.

    Nice also recommends self-management. This means giving patients information and leaving them to handle their own recovery. But recent research found that an online support programme was no better than usual care from their GP.

    For people with at least three months of lower back pain, Nice recommends “radio frequency denervation” as an option. This is a procedure where a probe is inserted into the back next to the nerve carrying pain signals from the back. Heating the probe can disable the nerves that carry pain signals. The problem is that some studies suggest it may help while others show no benefit.

    A more robust study is underway that will hopefully provide us with a more definitive answer. But, for now, we think this treatment should be approached with caution.

    Most Nice recommendations for the use of medications align with the current evidence. Nice recommends against the use of opioids for people with short-term back pain. However, the guidance suggests that weak opioids, such as codeine, can be considered if anti-inflammatory drugs are ineffective or “contraindicated” (should be avoided), for example, for people with previous stomach bleeding.

    This ambiguous approach is confusing and may result in people being given the wrong care. Also, a study published in 2023 showed that a stronger opioid does not help people with short-term back pain. Nice could adopt a clearer stance, explicitly discouraging opioid use for lower back pain.

    The guidance could focus on treatments where there’s strong evidence of benefit. One option is non-steroidal anti-inflammatory drugs, such as ibuprofen, which can be effective for treating people with acute and persistent symptoms. If this medication fails, heat therapy, such as hot packs and heat wraps, can be used for short-term lower back pain.

    Nice suggests that codeine can be used if the patient is unable to take anti-inflammatory medication, such as ibuprofen.

    Treating peristant lower back pain

    Exercise programmes can help people with persistent back pain. A recent study found that regular walking can help prevent lower back pain flare-ups.

    Approaches, such as cognitive functional therapy, where physiotherapists address both physical and psychological barriers to recovery, also show great promise. A recent study found that it offers lasting benefits when compared to a sham (placebo) intervention.

    Mindfulness, a type of meditation, also seems a promising approach for persistent pain. A new study, published in The Lancet Rheumatology showed that it can have meaningful and lasting benefits for these patients.

    Guidance from the World Health Organization recommends other treatments, such as manual therapy (spinal manipulation, for instance) and acupuncture, that could help people with persistent symptoms.

    It is clear that the Nice guidelines don’t always reflect what we now know works, and sometimes steer care in the wrong direction.

  • MIL-OSI Global: Police in England and Wales to get more money – but increasing funding won’t necessarily mean less crime

    Source: The Conversation – UK – By Graham Farrell, Professor of Crime Science, University of Leeds

    Ian Dewar Photography/Shutterstock

    Police spending will rise by a real-terms 2.3% per year between now and 2028-29, the government announced in its latest spending review, drawn from local council tax. The government says this will help its mission to put 13,000 neighbourhood police on the streets, and “keep communities safe”.

    Police say this is far from enough to meet the government’s ambitions, particularly on cutting knife crime and violence against women, and that it is likely to be “swallowed up” by pay rises for police.

    The awkward truth, however, is that marginal changes to police funding and hiring make little difference to crime either way. Austerity cuts of around 20% to policing budgets in the 2010s were accompanied by declining crime, including domestic violence and antisocial behaviour.

    Widespread security improvements were responsible for the close to 90% reductions in many crime types. For example, engine immobilisers prevent car theft, and secure household doors and windows prevent burglary.

    Crime has been declining across developed countries for decades. But those countries vary greatly in policing practices and funding, so it is clear more policing was not the cause.

    American policing researcher pioneer David Bayley wrote in 1994:

    The police do not prevent crime. This is one of the best kept secrets of modern life. Experts know it, the police know it, but the public does not know it. Yet the police pretend they are society’s best defense against crime and continually argue that if they are given more resources, especially personnel, they will be able to protect communities against crime. This is a myth.

    This does not mean we don’t need police – we do. If there were no police, crime rates would soar. The issue here is diminishing marginal returns (we’re at the level where more funding doesn’t have the same effect).

    But it means the spending review debate had little to do with crime prevention. Rather, it was about how senior staff in public services routinely seek more for their departments. And following the spending review, police chiefs gave themselves an escape clause by claiming the increase is insufficient.

    Sign up for our weekly politics newsletter, delivered every Friday.

    In recent years, we’ve learned problem-solving policing can reduce some crimes in some contexts. For example, burglary at construction sites can often be theft of building materials and tools, so the crime problem can be reduced through improved site management (rather than just more arrests).

    However, problem-solving is not easy and so is not widely applied. Simply patrolling hotspots does not affect the crime opportunity structure (factors that tempt, facilitate or precipitate a particular cluster of crimes).

    Additionally, all types of crime, except homicide, are more likely to recur, and relatively soon, after prior victimisation. And while policing to prevent repeat victimisation can reduce crime, it has fallen by the wayside in recent years.

    A recent review by crime scientist Shannon Linning and colleagues examined the effect of more police hiring and more arrests on crime, concluding: “When a sensational crime happens, residents demand action. Often someone will cry for more police and more arrests … neither approach is likely to be helpful.”

    This makes it rather awkward that the government has recently committed to recruiting 13,000 additional neighbourhood police.

    Since most people don’t know the limitations of policing, both the government and the police have been able to maintain the illusion that more police means less crime. Academic police researchers will rarely admit it in case it risks their funding, and the media enjoy a perennially newsworthy topic. Taxpayers foot the bill as well as the emotional, financial and other costs of crime.

    How to stop crime

    There is, however, some room for optimism. What we have learned from the long-term international crime drop and dozens of small-scale successes against different crime types is that reducing crime opportunities is the best approach. With some strategic adjustment, there is much that police and government can do.

    A particular focus for the government and police should be encouraging businesses to take more responsibility for crime. Knife manufacturers and retailers should be involved in introducing a ban on pointed kitchen knives, the most common homicide weapon in England and Wales. The gradual approach over many years that research (in which I was involved) recommended is too long: it should be done within this government’s term.

    A lot of other crimes, including computer-enabled crimes, are generated, facilitated or hosted by businesses. Internet service providers and network providers benefit from advertising and payments, including when they are being used for crime (from stalking and sexual victimisation to fraud and terrorism).

    Manufacturers benefit from theft of phones and other products that need replacing. Online marketplaces profit from usage and advertising when stolen goods are sold, which inadvertently encourages shoplifting, theft and robbery. Online banking and financial services also host significant amounts of fraud, and are now sometimes required to pay up to £85,000 compensation to victims.

    Government and police should develop a portfolio of incentives and disincentives to promote private sector crime prevention, to include regulation and market-based incentives. When businesses have an economic incentive they are tremendously efficient at preventing crime, as car manufacturers showed by improving security that brought 90% reductions in car crime.

    Reducing crime opportunities is also the best way to stop criminality. When young people do not get involved in easy crimes like shoplifting, they do not progress to further crime, including violence against women and girls.

    In short, extra police funding will not reduce crime. A shift in strategy is what is really needed.

  • MIL-OSI Global: Trump breaks from western allies at G7 summit as US weighs joining Iran strikes

    Source: The Conversation – UK – By Natasha Lindstaedt, Professor in the Department of Government, University of Essex

    Working alongside western democratic allies has not been a natural fit for Donald Trump. The US president left the recently concluded G7 summit in Canada early, with his French counterpart Emmanuel Macron assuming this was to work on addressing the most severe escalation between Iran and Israel in decades.

    But Trump offered little communication with other G7 members, which include Canada, France, Germany, Italy, Japan and the UK, of what his plans were. He said he had to leave the summit “for obvious reasons”, though failed to elaborate on what he meant.

    After exiting the summit, he lambasted Macron on social media. Trump wrote: “Wrong! He has no idea why I am now on my way to Washington, but it certainly has nothing to do with a Cease Fire”. Trump continued by saying his exit was due to something “much bigger than that”, adding: “Emmanuel always gets it wrong.”

    This has prompted discussion over whether US forces may join Israel’s strikes on Iran. Despite initially distancing the US from the Israeli attacks, Trump said on June 17: “We now have complete and total control of the skies over Iran.”

    He has since demanded Tehran’s “unconditional surrender”, while also issuing a chilling threat to Iran’s supreme leader, Ayatollah Ali Khamenei, describing him as an “easy target”.

    The pressure campaign employed by Israel’s prime minister, Benjamin Netanyahu, to convince Trump that the time is right for a military assault on Iran seems to be working.

    Exploiting Trump’s impulsive nature, Netanyahu may soon be able to convince Trump to give Israel what it needs to destroy Iran’s underground uranium enrichment sites: a 30,000-pound “bunker buster” bomb and a B-2 bomber to carry it.

    The US’s western allies have been left scrambling to interpret Trump’s social media posts and figure out the real reason he left the G7 summit early.

    The only aircraft capable of carrying ‘bunker-buster’ bombs is the B-2.

    This wasn’t the first time that Trump has left a G7 forum early. In 2018, the last time such a meeting was held in Canada, Trump also left early after Macron and the then Canadian prime minister, Justin Trudeau, promised to confront Trump over the imposition of tariffs on US allies.

    The latest G7 summit also wasn’t the first time Trump has treated traditional US allies with suspicion. Trump has cast doubt on US willingness to defend Nato allies if they don’t pay more for their own defence. He has repeatedly threatened to leave the alliance and has frequently denigrated it – even calling alliance members “delinquent”.

    Trump thinks the US gains an advantage by abandoning relationships with “free riders”. But experts have made clear alienating allies makes the US weaker. While the alliance system has given the US unprecedented influence over the foreign policies of US allies in the past, Trump’s pressure to increase their defence spending will make them more independent from the US in the long-term.

    Trump seems to prefer a world guided by short-term self-interest at the expense of long-term collective security. Indeed, with an “America first” agenda, multilateral cooperation is not Trump’s strong suit. With the G7, Trump is yet again making clear that he does not fit in, nor does he want to.

    Because the G7 is small and relatively homogenous in membership, meetings between members are supposed to promote collective and decisive decision-making. However, even the task of coming up with a joint statement on the escalating conflict between Iran and Israel proved challenging.

    Trump eventually joined other leaders in calling for deescalation in the Middle East, and the G7 was in agreement that Iran cannot acquire nuclear weapons. But Trump’s social media activity since then has left US allies in the dark over what role the US might play in the conflict.

    Trump also alarmed G7 members with calls for Russia to return to the forum. He claimed that the war in Ukraine would not have happened had Moscow not been ejected from the former G8 grouping in 2014.

    Then, on his way out of the summit, Trump bragged to reporters that Russia’s leader, Vladimir Putin, “doesn’t speak to anybody else” but him. Trump added that Putin was insulted when Russia was thrown out of the G8, “as I would be, as you would be, as anybody would be”.

    Following weeks of frustration over Russia’s refusal to engage in serious peace talks about ending the war in Ukraine, Trump seems to have returned to being Putin’s most loyal advocate.

    Hostility toward multilateralism

    During Trump’s first term, he pushed multilateralism to the brink. But he did not completely disengage. The US withdrew from the Paris climate accords, the nuclear deal with Iran, negotiations for a trade deal with Pacific nations, and imposed sanctions against officials of the International Criminal Court.

    However, when multilateral initiatives served Trump’s short-term objectives, he was willing to get on board. A trade deal struck with Canada and Mexico that Trump described as “the most important” ever agreed by the US. He said the deal would bring thousands of jobs back to North America.

    The second Trump administration has been even more hostile to multilateralism. Not only has the trade deal with Canada and Mexico been undermined by Trump’s love of tariffs, his administration has been more antagonistic toward almost all of the US’s traditional allies. In fact, most of Trump’s ire is reserved for democracies not autocracies.

    In contrast to the G7, where he clearly felt out of place, Trump was in his element during his May trip to the Middle East. Trump has a more natural connection to the leaders of the Gulf who do not have to adhere to democratic norms and human rights, and where deals can get done immediately.

    Trump left the Middle East revelling in all of the billion dollar deals he made, which he exaggerated were worth US$2 trillion (£1.5 trillion). The G7, on the other hand, doesn’t offer much to Trump. He sees it as more of a nuisance.

    The G7 forum is supposed to reassure the public that the most powerful countries in the world are united in their commitment to stability. But Trump’s antics are undermining the credibility of that message. It is these antics that risk dragging the west into a dangerous confrontation with Iran.

  • MIL-OSI Global: What happens when aid is cut to a large refugee camp? Kenyan study paints a bleak picture

    Source: The Conversation – Africa – By Olivier Sterck, Associate professor, University of Oxford

    Humanitarian needs are rising around the world. At the same time, major donors such as the US and the UK are pulling back support, placing increasing strain on already overstretched aid systems.

    Global humanitarian needs have quadrupled since 2015, driven by new conflicts in Sudan, Ukraine and Gaza. Added to these are protracted crises in Yemen, Somalia, South Sudan, and DR Congo, among others. Yet donor funding has failed to keep pace, covering less than half of the requested US$50 billion in 2024, leaving millions without assistance.

    Notably, the US recently slashed billions of US dollars from global relief efforts. The slashed contributions once made up to half of all public humanitarian funding and over a fifth of the UN’s budget. Other donors have been cutting aid as well.

    As funding shortfalls widen, humanitarian agencies increasingly face tough choices: reducing the scale of operations, pausing essential services, or cancelling programmes altogether. Disruptions to aid delivery have become a routine feature of humanitarian operations.

    Yet few rigorous studies have provided hard evidence of the consequences for affected populations.

    A recent study from one of the world’s largest refugee camps in Kenya fills this gap.

    Our research team from the University of Oxford and the University of Antwerp was already studying Kakuma camp and then had an opportunity to see what happened when aid was cut. We observed the impact of a 20% aid cut that occurred in 2023.

    The study reveals that cuts to humanitarian assistance had dramatic impacts on hunger and psychological distress, with cascading effects on local credit systems and prices of goods.

    Kakuma refugee camp

    Kakuma is home to more than 300,000 refugees, who mostly came from South Sudan (49%), Somalia (16%), and the Democratic Republic of Congo (DRC) (10%). They have been housed here since 1992. With widespread poverty, lack of income opportunities, and aid making up over 90% of household income, survival in the camp hinges on humanitarian support from UN organisations.

    When the research began in late 2022, most refugees in Kakuma received a combination of in-kind and cash transfers from the World Food Programme. Transfers were worth US$17 per person per month, barely enough to cover the bare essentials: food, firewood and medicine.

    Over the span of a year, the research team tracked 622 South Sudanese refugee households, interviewing them monthly to monitor how their living conditions evolved in response to the timing and level of aid they received. We also gathered weekly price data on 70 essential goods and conducted more than 250 in-depth interviews with refugees, shopkeepers, and humanitarian staff to understand the broader impacts.

    Then came the cut. In July 2023, assistance was reduced by 20%, just as the research team was conducting its eighth round of data collection. This sudden reduction in humanitarian aid created a rare opportunity to assess the effects of an aid cut on both recipients and the markets they depend on.

    Consequences of aid cut

    The 20% cut in humanitarian aid had cascading effects, affecting not just hunger, but local credit systems, prices, and well-being.

    1. Hunger got worse. As a Somali refugee interviewed by the researchers put it: “After the aid reduction, the lives of refugees become hard. That was the money sustaining them. […] Things are insufficient, and hunger is visible.”

    Food insecurity was already widespread before the cut, with more than 90% of refugees classified as food insecure. Average caloric intake stood below 1,900 kcal per person per day – well under the World Food Programme’s 2,100 kcal target and about half the average daily calorie supply available to a US citizen.

    Food insecurity further increased following the aid cut, with caloric intake falling by 145 kcal, a 7% decrease. The share of households eating one meal or less increased by 8 percentage points, from about 29% to 37%. At the same time, dietary diversity narrowed, indicating that households tried to mitigate the negative impacts of the aid cut by reducing the variety of foods they consumed.

    2. Credit collapsed. As a refugee shopkeeper of Ethiopian origin reported: “When we give out credit we have a limit; since the aid is reduced, the credit is also reduced.”

    Cash assistance in Kakuma is delivered through aid cards, which refugees routinely use as collateral to access food on credit. When transfers are delayed or unexpected expenses arise, refugees hand over their aid cards as a guarantee to trusted shopkeepers, allowing them to borrow food against next month’s aid.

    But when assistance was cut, the value of this informal collateral plummeted. Retailers, fearing default, reduced lending or refused lending altogether. Informal credit from shopkeepers shrank by 9%. Many refugees reported being refused food on credit or having to repay past debt before receiving any new goods.

    3. Households liquidated assets. With no access to credit, households began selling off possessions and drawing down food reserves. The average value of household assets fell by over 6% after the aid cut.

    4. Psychological distress increased. The aid cut reduced self-reported sleep quality and happiness, indicating that reductions in aid go beyond physical impacts and also have psychological effects.

    5. Prices fell. With reduced expenditure and purchasing power, the demand for food dropped, and food prices went down, partially offsetting the negative effects of the aid cut.

    Implications

    The study carries two major policy implications.

    First, aid in contexts like Kakuma should not be treated as optional or discretionary, but as a structural necessity. It is the backbone of daily life. Mechanisms are needed to protect it from abrupt donor withdrawals.

    Second, informal credit is not peripheral, it is central to economic life in refugee settings. In many camps, shopkeepers act as retailers and de facto financial institutions. When aid transfers serve as both income and collateral, cutting them risks collapsing this fragile credit system. Cash transfer programmes must therefore be designed with these dynamics in mind.

  • MIL-OSI Global: Nigeria’s economy is growing but rural poverty is rising: 5 key policies to address the divide

    Source: The Conversation – Africa – By Stephen Onyeiwu, Professor of Economics & Business, Allegheny College

    The Nigerian economy grew at a robust rate of 3.4% in 2024, the highest it has been since 2019 (except 2021 when the COVID rebound occurred).

    This should have been cheering news, worthy of firecrackers and champagne-popping. Rather it came with a catch: the country’s poverty profile worsened.

    In its annual review of the country, the World Bank applauded Nigeria for its economic reforms. These include the removal of fuel subsidies, liberalisation of the foreign exchange market and maintenance of a contractionary monetary policy. This is a policy of raising interest rates, reducing money supply and increasing borrowing costs to rein in inflation.

    But the bank also drew attention to the fact that the country’s poverty profile has become grim. About 31% of Nigerians lived in poverty prior to the COVID-19 epidemic. Since then, an additional 42 million have become poor, increasing the poverty rate to about 46% in 2024.

    Poverty is even worse in Nigeria’s rural communities: 75.5% live on US$2.15 or less per day (based on 2017 prices). The average poverty rate for sub-Saharan African countries was 36.5% in 2024 and 0.8% for East Asia and the Pacific.

    Nigeria’s poverty rate would have been higher if the multidimensional poverty index had been used. In addition to income, the index considers access to education, health, decent housing, nutrition, sanitation, electricity and water. Access to these critical services has worsened for many Nigerians, despite improvements in macroeconomic stability.

    A challenge for policy makers is how to translate impressive macroeconomic outcomes into high-paying jobs, lower poverty rates and access to health, good sanitation, education, electricity and affordable housing. The question is even more acute for people in rural areas.

    As an economist who has studied the Nigerian economy for over four decades and lived in a rural community, I believe Nigeria needs a radical shift in its economic policy approach.

    One major step should be a change in the country’s growth drivers. Oil, information and communications technology and finance are the major drivers of growth in Nigeria.

    These sectors are not employment-intensive, and they require skills that most Nigerians don’t have. Because of the lack of employment opportunities in these sectors, most Nigerians gravitate towards the informal sector, which accounts for about 90% of employment in the country.

    By continuing to urge Nigerians to be patient for economic reforms to have a positive impact on their living conditions, the Tinubu administration appears to assume that improvements in macroeconomic performance will eventually manifest in lower unemployment and poverty rates. This notion of “trickle-down economics” is misconceived and illusory.

    The government needs to intentionally create transmission mechanisms through which economic growth and macroeconomic stability can raise living standards.

    Fostering growth with development

    Concerted efforts will be needed to target poverty in general, and rural poverty in particular.

    Five key policies could get Nigeria closer to this goal:

    Building productive capacities: People who live in rural areas in Nigeria are eager to work and full of creative ideas and entrepreneurial spirit. But they lack the resources and opportunity to fully unleash their potential.

    Building their productive capacities would entail giving them access to basic education, technical and managerial skills, and other productive resources such as tools, equipment, finance and land. The government should identify the comparative advantage of different rural communities, and put in place policies that encourage those communities to use their comparative advantage and distinctive competencies.

    Opportunity to diversify incomes: In developed countries, many people hold multiple jobs. Most rural dwellers in Nigeria, however, rely on agriculture as their only source of livelihood.

    Because of limited access to inputs and modern technology, and outdated agricultural practices, their productivity is often very low. Their low income makes it difficult to save and invest in education, health and housing.

    Non-agricultural activities, especially manufacturing, need to be located in rural communities, to give rural dwellers the opportunity to diversify their income sources.

    Agriculture-led industrial strategy: This would involve the location of manufacturing plants close to the sources of agricultural raw materials.

    Nigerian manufacturers locate their factories in urban areas. The result of urban-biased development strategy in Nigeria has been the lack of employment opportunities in rural communities, and a decline in the rural population, from about 85% in 1960 to 46% in 2023.

    Moving manufacturing to rural areas would require massive investment in infrastructure such as electricity, water, roads and health services.

    Ending patriarchy and male domination: Women disproportionately bear the burden of rural poverty in Nigeria. A study in rural south-east Nigeria found that the poverty rate among women was 98%, compared to 85% for men. Men are often given preference regarding access to land, education, skills acquisition and financial inclusion.

    Women are also imbued with the responsibility of caring for children, the elderly and the sick, as well as household chores. This leaves them with little time for paid work or opportunities to acquire marketable skills.

    Ability to absorb shocks and vulnerability: Rural poverty is often exacerbated by shocks and vulnerability such as extreme weather conditions, attacks by insurgents and other criminal groups, and illness. With no safety nets, and little or no saving, most rural dwellers are unable to withstand shocks.

    The Tinubu administration plans to disburse N25,000 (about US$17) each to 60 million Nigerians. But these kinds of support are too small, non-pervasive, irregular and unpredictable.

    What India and China have to teach

    Nigeria could do well to borrow from the Indian model of an institutionalised safety net.

    India issues “ration cards” to eligible households. The cards enable poor people to purchase essential food items such as grains, milk, eggs, cooking oil and bread at subsidised prices from designated stores.

    Nigeria could finance this kind of programme with a special tax on oil companies and financial institutions, which frequently post huge after-tax profits.

    China has had an impressive record of poverty reduction. Using the US$1.90 poverty line, China’s poverty rate decreased from 88.1% in 1981 to 0.3% in 2018.

    The fall in rural poverty is even more dramatic, from 96% in 1980 to 1% in 2019.

    This reduction was accomplished in stages, starting with an increase in agricultural productivity. It then shifted focus to the development of non-agricultural sectors of the economy, including manufacturing. These sectors were able to draw surplus labour from the agricultural sector, giving them skills that led to higher wages and poverty alleviation.

    Next steps

    The World Bank in its report noted that addressing pressing social and humanitarian challenges remains critical to ensuring inclusive and sustainable growth in Nigeria.

    Cash transfers and social assistance programmes could provide temporary relief for the poor in rural communities. But a long-term solution is to build their productive capacities and transform rural communities in ways that provide opportunities for income diversification.

    The summer of 1975 was the summer of “Jaws.”

    The movie was adapted from a novel by Peter Benchley.

    The first blockbuster movie sent waves of panic and awe through audiences. “Jaws” – the tale of a killer great white shark that terrorizes a coastal tourist town – captured people’s imaginations and simultaneously created a widespread fear of the water.

    To call Steven Spielberg’s masterpiece a creature feature is trite. Because the shark isn’t shown for most of the movie – mechanical difficulties meant production didn’t have one ready to use until later in the filming process – suspense and fear build. The movie unlocked in viewers an innate fear of the unknown, encouraging the idea that monsters lurk beneath the ocean’s surface, even in the shallows.

    And because in 1975 marine scientists knew far less than we do now about sharks and their world, it was easy for the myth of the rogue shark as a murderous eating machine to take hold, along with the assumption that all sharks must be bloodthirsty, mindless killers.

    But in addition to scaring many moviegoers that “it’s not safe to go in the water,” “Jaws” has over the years inspired generations of researchers, including me. The scientific curiosity sparked by this horror fish flick has helped reveal so much more about what lies beneath the waves than was known 50 years ago. My own research focuses on the secret lives of sharks, their evolution and development, and how people can benefit from the study of these enigmatic animals.

    The business end of sharks: Their jaws and teeth

    My own work has focused on perhaps the most terrifying aspect of these apex predators, the jaws and teeth. I study the development of shark teeth in embryos.

    Ella Nicklin, Fraser Lab, University of Florida

    Sharks continue to make an unlimited supply of tooth replacements throughout life – it’s how they keep their bite constantly sharp.

    Hard-shelled prey, such as mollusks and crustaceans, from sandy substrates can be more abrasive for teeth, requiring quicker replacement. Depending on the water temperature, the conveyor belt-like renewal of an entire row of teeth can take between nine and 70 days, for example, in nurse sharks, or much longer in larger sharks. In the great white, a full-row replacement can take an estimated 250 days. That’s still an advantage over humans – we never regrow damaged or worn-out adult teeth.

    Gareth Fraser, University of Florida

    Interestingly, shark teeth are much like our own, developing from equivalent cells, patterned by the same genes, creating the same hard tissues, enamel and dentin. Sharks could potentially teach researchers how to master the process of tooth renewal. It would be huge for dentistry if scientists could use sharks to figure out how to engineer a new generation of teeth for human patients.

    Extraordinary fish with extraordinary biology

    As a group, sharks and their cartilaginous fish relatives – including skates, rays and chimaeras – are evolutionary relics that have inhabited the Earth’s oceans for over 400 million years. They’ve been around since long before human beings and most of the other animals on our planet today hit the scene, even before dinosaurs emerged.

    Sharks have a vast array of super powers that scientists have only recently discovered.

    Their electroreceptive pores, located around the head and jaws, have amazing sensory capabilities, allowing sharks to detect weak electrical fields emitted from hidden prey.

    Their skin is protected with an armor of tiny teeth, called dermal denticles, composed of sensitive dentin, that also allows for better drag-reducing hydrodynamics. Biologists and engineers are also using this “shark skin technology” to design hydrodynamic and aerodynamic solutions for future fuel-efficient vehicles.

    Some sharks are biofluorescent, meaning they emit light in different wavelengths after absorbing natural blue light. This emitted fluorescent color pattern suggests visual communication and recognition among members of the same species is possible in the dark depths.

    Sharks can migrate across huge global distances. For example, a silky shark was recorded traveling 17,000 miles (over 27,000 kilometers) over a year and a half. Hammerhead sharks can even home in on the Earth’s magnetic field to help them navigate.

    Greenland sharks exhibit a lengthy aging process and live for hundreds of years. Scientists estimated that one individual was 392 years old, give or take 120 years.

    Still much about sharks remains mysterious. We know little about their breeding habits and locations of their nursery grounds. Conservation efforts are beginning to target the identification of shark nurseries as a way to manage and protect fragile populations.

    Tagging programs and their “follow the shark” apps allow researchers to learn more about these animals’ lives and where they roam – highlighting the benefit of international collaboration and public engagement for conserving threatened shark populations.

    Sharks under attack

    Sharks are an incredible evolutionary success story. But they’re also vulnerable in the modern age of human-ocean interactions.

    Sharks are an afterthought for the commercial fishing industry, but overfishing of other species can cause dramatic crashes in shark populations. Their late age of sexual maturity – as old as 15 to 20 years or more in larger species or potentially 150 years in Greenland sharks – along with slow growth, long gestation periods and complex social structures make shark populations fragile and less capable of quick recoveries.

    Take the white shark (Carcharodon carcharias), for example – Jaws’ own species. Trophy hunting, trade in their body parts and commercial fishery impacts caused their numbers to dwindle. As a result, they received essential protections at the international level. In turn, their numbers have rebounded, especially around the United States, leading to a shift from critically endangered to vulnerable status worldwide. However, they remain critically endangered in Europe and the Mediterranean.

    Protections and conservation measures have helped white sharks make a comeback.
    Dave Fleetham/Design Pics Editorial/Universal Images Group via Getty Images

    “Jaws” was filmed on the island of Martha’s Vineyard, in Massachusetts. After careful management and the designation of white sharks as a prohibited species in federal waters in 1997 and in Massachusetts in 2005, their populations have recovered well over recent years in response to more seals in the area and recovering fish stocks.

    You might assume more sharks would mean more attacks, but that is not what we observe. Shark attacks have always been few and far between in Massachusetts and elsewhere, and they remain rare. It’s only a “Jaws”-perpetuated myth that sharks have a taste for humans. Sure, they might mistake a person for prey; for instance, surfers and swimmers can mimic the appearance of seals at the surface. Sharks in murky water might opportunistically take a test bite of what seem to be prey.

    But these attacks are rare enough that people can shed their “Jaws”-driven irrational fears of sharks. Almost all sharks are timid, and the likelihood of an interaction – let alone a negative one – is incredibly rare. Importantly, there more than 500 species of sharks in the world’s oceans, each one a unique member of a particular ecosystem with a vital role. Sharks come in all shapes and sizes, and inhabit every ocean, both the shallow and deep-end ecosystems.

    Most recorded human-shark interactions are awe-inspiring and not terrifying. Sharks don’t really care about people – at most they may be curious, but not hungry for human flesh. Whether or not “Jaws” fans have grown beyond the fear of movie monster sharks, we’re gonna need a bigger conservation effort to continue to protect these important ocean guardians.

    “Da, duh.”

    Two simple notes – E and F – have become synonymous with tension, fear and sharks, representing the primal dread of being stalked by a predator.

    And they largely have “Jaws” to thank.

    Fifty years ago, Steven Spielberg’s blockbuster film – along with its spooky score composed by John Williams – convinced generations of swimmers to think twice before going in the water.

    As a scholar of media history and popular culture, I decided to take a deeper dive into the staying power of these two notes and learned about how they’re influenced by 19th-century classical music, Mickey Mouse and Alfred Hitchcock.

    When John Williams proposed the two-note theme for ‘Jaws,’ Steven Spielberg initially thought it was a joke.

    YouTube video not showing up for me

    The first summer blockbuster

    In 1964, fisherman Frank Mundus killed a 4,500-pound great white shark off Long Island.

    After hearing the story, freelance journalist Peter Benchley began pitching a novel based on three men’s attempt to capture a man-eating shark, basing the character of Quint off of Mundus. Doubleday commissioned Benchley to write the novel, and in 1973, Universal Studios producers Richard D. Zanuck and David Brown purchased the film rights to the novel before it was published. The 26-year-old Spielberg was signed on to be the director.

    Tapping into both mythical and real fears regarding great white sharks – including an infamous set of shark attacks along the Jersey Shore in 1916 – Benchley’s 1974 novel became a bestseller. The book was a key part of Universal’s marketing campaign, which began several months before the film’s release.

    Starting in the fall of 1974, Zanuck, Brown and Benchley appeared on a number of radio and television programs to simultaneously promote the release of the paperback edition of the novel and the upcoming film. The marketing also included a national television advertising campaign that featured emerging composer Williams’ two-note theme. The plan was for a summer release, which, at the time, was reserved for films with less than stellar reviews.

    TV ads promoting the film featured John Williams’ two-note theme.

    Films at the time typically were released market by market, preceded by local reviews. However, Universal’s decision to release the film in hundreds of theaters across the country on June 20, 1975, led to huge up-front profits, sparking a 14-week run as the No. 1 film in the U.S.

    Many consider “Jaws” the first true summer blockbuster. It catapulted Spielberg to fame and kicked off the director’s long collaboration with Williams, who would go on to earn the second-highest number of Academy Award nominations in history – 54 – behind only Walt Disney’s 59.

    The film’s beating heart

    Though it’s now considered one of the greatest scores in film history, when Williams proposed the two-note theme, Spielberg initially thought it was a joke.

    But Williams had been inspired by 19th and 20th century composers, including Claude Debussy, Igor Stravinsky and especially Antonin Dvorak’s Symphony No. 9, “From the New World.” In the “Jaws” theme, you can hear echoes of the end of Dvorak’s symphony, as well as the sounds of another character-driven musical piece, Sergei Prokofiev’s “Peter and the Wolf.”

    “Peter and the Wolf” and the score from “Jaws” are both prime examples of leitmotifs, or a musical piece that represents a place or character.

    The varying pace of the ostinato – a musical motif that repeats itself – elicits intensifying degrees of emotion and fear. This became more integral as Spielberg and the technical team struggled with the malfunctioning pneumatic sharks that they’d nicknamed “Bruce,” after Spielberg’s lawyer.

    As a result, the shark does not appear until the 81-minute mark of the 124-minute film. But its presence is felt through Williams’ theme, which some music scholars have theorized evoke the shark’s heartbeat.

    Sounds to manipulate emotions

    Williams also has Disney to thank for revolutionizing character-driven music in film.

    The two don’t just share a brimming trophy case. They also understood how music can heighten emotion and magnify action for audiences.

    Although his career started in the silent film era, Disney became a titan of film, and later media, by leveraging sound to establish one of the greatest stars in media history, Mickey Mouse.

    When Disney saw “The Jazz Singer” in 1927, he knew that sound would be the future of film.

    On Nov. 18, 1928, “Steamboat Willie” premiered at Universal’s Colony Theater in New York City as Disney’s first animated film to incorporate synchronized sound.

    Unlike previous attempts to bring sound to film by having record players concurrently play or deploying live musicians to perform in the theater, Disney used technology that recorded sound directly on the film reel.

    It wasn’t the first animated film with synchronized sound, but it was a technical improvement to previous attempts at it, and “Steamboat Willie” became an international hit, launching Mickey’s – and Disney’s – career.

    The use of music or sound to match the rhythm of the characters on screen became known as “Mickey Mousing.”

    “King Kong” in 1933 would deftly deploy Mickey Mousing in a live action film, with music mimicking the giant gorilla’s movements. For example, in one scene, Kong carries away Ann Darrow, who’s played by actress Fay Wray. Composer Max Steiner uses lighter tones to convey Kong’s curiosity as he holds Ann, followed by ominous, faster, tones as Ann escapes and Kong chases after her. In doing so, Steiner encourages viewers to both fear and connect with the beast throughout the film, helping them suspend disbelief and enter a world of fantasy.

    Mickey Mousing declined in popularity after World War II. Many filmmakers saw it as juvenile and too simplistic for the evolving and advancing film industry.

    When less is more

    In spite of this criticism, the technique was still used to score some iconic scenes, like the playing of violins in the shower as Marion Crane is stabbed in Alfred Hitchcock’s “Psycho.”

    Spielberg idolized Hitchcock. A young Spielberg was even kicked off the Universal lot after sneaking on to watch the production of Hitchcock’s 1966 film “Torn Curtain.”

    Although Hitchcock and Spielberg never met, “Jaws” clearly exhibits the influence of Hitchcock, the “Master of Suspense.” And maybe that’s why Spielberg initially overcame his doubts about using something so simple to represent tension in the thriller.

    The use of the two-note motif helps overcome the production issues Spielberg faced directing the first feature length movie to be filmed on the ocean. The malfunctioning animatronic shark forced Spielberg to leverage Williams’ minimalist theme to represent the shark’s ominous presence in spite of the limited appearances by the eponymous predatory star.

    As Williams continued his legendary career, he would deploy a similar sonic motif for certain “Star Wars” characters. Each time Darth Vader appeared, the “Imperial March” was played to set the tone for the leader of the dark side.

    As movie budgets creep closer to a half-billion dollars, the “Jaws” theme – and the way those two notes manipulate tension – is a reminder that in film, sometimes less can be more.

  • MIL-OSI Global: Ticks carry decades of history in each troublesome bite

    When you think about ticks, you might picture nightmarish little parasites, stalking you on weekend hikes or afternoons in the park.

    Your fear is well-founded. Tick-borne diseases are the most prevalent vector-borne diseases – those transmitted by living organisms – in the United States. Each tick feeds on multiple animals throughout its life, absorbing viruses and bacteria along the way and passing them on with its next bite. Some of those viruses and bacteria are harmful to humans, causing diseases that can be debilitating and sometimes lethal without treatment, such as Lyme, babesiosis and Rocky Mountain spotted fever.

    But contained in every bite of this infuriating, insatiable pest is also a trove of social, environmental and epidemiological history.

    In many cases, human actions long ago are the reason ticks carry these diseases so widely today. And that’s what makes ticks fascinating for environmental historians like me.

    Changing forests fueled tick risks

    During the 18th and 19th centuries, settlers cleared more than half the forested land across the northeastern U.S., cutting down forests for timber and to make way for farms, towns and mining operations. With large-scale land clearing came a sharp decline in wildlife of all kinds. Predators such as bears and wolves were driven out, as were deer.

    As farming moved westward, Northeasterners began to recognize the ecological and economic value of trees, and they returned millions of acres to forest.

    The woods regrew. Plant-eaters such as deer returned, but the apex predators that once kept their populations in check did not.

    As a result, deer populations carrying borrelia burgdorferi, the bacterium that causes Lyme disease, grew rapidly. And with the deer came deer ticks (Ixodes scapularis). When a tick feeds on an infected deer, it can take up the bacteria. The tick isn’t harmed, but it can pass the bacteria to its next victim. In humans, Lyme disease can cause fever and fatigue, and if left untreated it can affect the nervous system.

    The eastern U.S. became a global hot spot for tick-borne Lyme disease starting around the 1970s. Lyme disease affected over 89,000 Americans in 2023, and possibly many more.

    Californians move into tick territory

    For centuries, changing patterns of human settlements and the politics of land use have shaped the role of ticks and tick-borne illnesses within their environments.

    In short, humans have made it easier for ticks to thrive and spread disease in our midst.

    In California, the Northern Inner Coast and Santa Cruz mountain ranges that converge on San Francisco from the north and south were never clear-cut, and predators such as mountain lions and coyotes still exist there. But competition for housing has pushed human settlement deeper into wildland areas to the north, south and east of the city, reshaping tick ecology there.

    While western black-legged ticks (Ixodes pacificus) tend to swarm in large forest preserves, the Lyme-causing bacterium is actually more prevalent in small, isolated patches of greenery. In these isolated patches, rodents and other tick hosts can thrive, safe from large predators, which need more habitat to move freely. But isolation and lower diversity also means infections are spread more easily within the tick’s host populations.

    People tend to build isolated houses in the hills, rather than large, connected developments. As the Silicon Valley area south of San Francisco sprawls outward, this checkerboard pattern of settlement has fragmented the natural landscape, creating a hard-to-manage public health threat.

    Fewer hosts, more tightly packed, often means more infected hosts, proportionally, and thus more dangerous ticks.

    Six counties across these ranges, all surrounding and including San Francisco, account for 44% of recorded tick-borne illnesses in California.

    A lesson from Texas cattle ranches

    Domesticated livestock have also shaped the disease threat posed by ticks.

    In 1892, at a meeting of cattle ranchers at the Stock Raiser’s Convention in Austin, Texas, Dr. B.A. Rogers introduced a novel theory that ticks were behind recent devastating plagues of Texas cattle fever. The disease had arrived with cattle imported from the West Indies and Mexico in the 1600s, and it was taking huge tolls on cattle herds. But how the disease spread to new victims had been a mystery.

    Editors of Daniel’s Texas Medical Journal found the idea of ticks spreading disease laughable and lampooned the hypothesis, publishing a satire of what they described as an “early copy” of a forthcoming report on the subject.

    The tick’s “fluid secretion, it is believed, is the poison which causes the fever … [and the tick] having been known to chew tobacco, as all other Texans do, the secretion is most probably tobacco juice,” they wrote.

    Fortunately for the ranchers, not to mention the cows, the U.S. Department of Agriculture sided with Rogers. Its cattle fever tick program, started in 1906, curbed cattle fever outbreaks by limiting where and when cattle should cross tick-dense areas.

    By 1938, the government had established a quarantine zone that extended 580 miles by 10 miles along the U.S.-Mexico border in South Texas Brush Country, a region favored by the cattle tick.

    This innovative use of natural space as a public health tool helped to functionally eradicate cattle fever from 14 Southern states by 1943.

    Ticks are products of their environment

    When it comes to tick-borne diseases the world over, location matters.

    Take the hunter tick (Hyalomma spp.) of the Mediterranean and Asia. As a juvenile, or nymph, these ticks feed on small forest animals such as mice, hares and voles, but as an adult they prefer domesticated livestock.

    For centuries, this tick was an occasional nuisance to nomadic shepherds of the Middle East. But in the 1850s, the Ottoman Empire passed laws to force nomadic tribes to become settled farmers instead. Unclaimed lands, especially on the forested edges of the steppe, were offered to settlers, creating ideal conditions for hunter ticks.

    As a result, farmers in what today is Turkey saw spikes in tick-borne diseases, including a virus that causes Crimean-Congo hemorrhagic fever, a potentially fatal condition.

    Where to check for ticks and how to remove them.

    It’s probably too much to ask for sympathy for any ticks you meet this summer. They are bloodsucking parasites, after all.

    Still, it’s worth remembering that the tick’s malevolence isn’t its own fault. Ticks are products of their environment, and humans have played many roles in turning them into the harmful parasites that seek us out today.

    Sean Lawrence has nothing to disclose.
