    If you walk through a forest and look down, you might think you’re stepping on dead leaves, twigs and soil. In reality, you’re walking over a vast underground patchwork of fungal filaments, supporting life above ground.

    These are mycorrhizal fungi, which form partnerships with the roots of nearly all plants. Found everywhere from tropical rainforests to boreal forests and farmland, these underground fungi sustain life above ground, often without us realising they’re even there.

    A recent academic review argues that up to 83% of ectomycorrhizal (ECM) fungi species, which form partnerships with trees, may be unknown to science.

    Mycorrhizal fungi grow around root tips and form webs between root cells or penetrate root cells, then make structures inside them. They scavenge nutrients such as phosphorus and nitrogen from the soil and, in return, receive carbon from their host plants.

    Traces of these unidentified fungi are often found in soil DNA. The researchers surveyed global DNA databases to see how many DNA traces that seemed to belong to ECM fungi matched to a species. Only 17% could. Scientists call these “dark taxa” – organisms that have been detected, but not formally described, named or studied.

    Many of these fungi produce large fruiting bodies such as mushrooms and are foundational to forest ecosystems.

    One example is the fly agaric (Amanita muscaria) which produces the iconic red and white spotted toadstools often linked to folklore and can have a range of host trees. It typically associates with birch, pine and spruce, especially in colder climates, helping trees survive in nutrient-poor soils.

    Porcini fungi, (for example Boletus edulis), produce delicious mushrooms prized for their rich, nutty flavor, are ECMs too. These fungi grow with pines, firs and oaks. And the chanterelle is highly sought-after by mushroom collectors and often found near oaks, beech and conifers.

    Chanterelles thrive in undisturbed, healthy forests. Their presence often signals a well-functioning forest ecosystem. They have a fruity, apricot-like scent that may attract insects to help spread spores.

    The new report shows how little we know about the world beneath our feet. This ignorance has important implications. Entire landscapes are being reshaped by deforestation and agriculture.

    But reforestation efforts are happening without fully understanding how these changes affect the fungal life that underpins these ecosystems. For example, in the Amazon, deforestation for farming continues at an alarming pace with 3,800 square miles (equivalent to 1.8 million football fields) of tropical rainforest destroyed for beef production in 2018-19 alone.

    Meanwhile, well-meaning carbon offset schemes often involve planting trees of a single species, potentially severing ancient relationships between native trees and their fungal partners. This is because the mycorrhizal fungi in these area will have developed in partnership with the native plants for many years – and may not be compatible with the tree species being planted for these schemes.

    Although not all trees have specific fungal partners, many ECM fungi will only form symbioses with certain trees. For example, species within the Suillus genus (which includes the sticky bun mushroom) are specific to certain species of pine.

    Introducing non-native plantation species may inadvertently drive endemic fungi, including species not yet known to science, toward extinction. We may be growing forests that look green and vibrant, but are damaging the invisible systems that keep them alive.

    The problem isn’t limited to ECM fungi. Entire guilds (species groups that exploit resources in a similar way) of mycorrhizal fungi, remain virtually unexplored.

    These dark guilds are ecologically crucial, yet most of their members have never been named, cultured or studied.

    Ericoid Mycorrhizal Fungi (ERM)

    These fungi form symbioses with many ericaceous shrubs, including heather, cranberry and rhododendrons. They dominate in some of the world’s harshest landscapes, including the Arctic tundra, the boreal forest (also known as snow forest), bogs and mountains.

    Research suggests ERM fungi not only help plants thrive in harsh environments but also drive some of the carbon accumulation in these environments, making them potentially part of an important carbon sink.

    Despite their abundant coverage across some of the most carbon-rich soils on Earth, the ecology of ERM fungi remains somewhat mysterious. Only a small number have been formally identified. However, even the few known species suggest remarkable potential.

    Their genomes contain vast repertoires of genes for breaking down organic matter. This is important because it suggests ERM fungi are not just symbionts living in close interaction with other species but also active decomposers, influencing both plant nutrition and soil carbon cycling. Their dual lifestyle may play a critical role in nutrient-poor ecosystems.

    Mucoromycotina fine root endophytes (MFRE)

    MFRE are another group of enigmatic fungi that form beneficial relationships with plants. Long mistaken for the arbuscular mycorrhizal (AM) fungi until distinguished in 2017, MFRE are also found across a range of ecosystems including farmland and nutrient-poor soils and often live alongside AM fungi.

    MFRE appear to be important in helping plants access nitrogen from within the soil, while AM fungi are more associated with phosphorus uptake. Like ERM fungi, MFRE appear to also alternate between free-living and symbiotic lifestyles.

    As researchers begin to uncover their roles, MFRE are emerging as important players in plant resilience and sustainable agriculture.

    These fungi frequently appear in plant roots. They are characterised by darkly pigmented, segmented fungal filaments, or hyphae, but their role is highly context-dependent.

    Some DSEs appear to enhance host stress tolerance or nutrient uptake. Others may act as latent pathogens, potentially harming the host plant. Most DSEs remain unnamed and poorly understood.

    Time is running out

    Many of the ecosystems connected to these dark guilds of fungi are among the most vulnerable on the planet. The Arctic and alpine regions which are strongholds for ERMs, DSEs and potentially MFREs, are warming at two to four times the global average.

    Peatlands have been drained and converted for agriculture or development while heathlands are increasingly targeted for tree-planting initiatives meant to sequester carbon.

    Planting fast-growing, non-native species in monocultures may improve short-term carbon metrics above ground, but it could come at the cost of soil health and belowground biodiversity. Many fungi are host-specific, co-evolving with native plants over millions of years.

    Replacing those plants with non-native trees or allowing invasive plants to spread could lead to local extinctions of fungi we’ve never had the chance to study. Soil fungi also mediate processes from nutrient cycling to pathogen suppression to carbon sequestration.

    We are changing landscapes faster than we can understand them and in doing so we may be unravelling critical ecological systems that took millennia to form.

  • MIL-OSI Analysis: Why the l-carnitine sport supplement is controversial

    Source: The Conversation – UK – By Julia Haarhuis, PhD student – Food, Microbiomes and Health, Quadram Institute

    Sport supplements are hard to get away from if you like to exercise regularly. Even if you’re not interested in them, there’s a good chance your gym will have posters extolling their virtues or your sporty friends will want to talk to you about them.

    It can be hard to know what supplements to take as there is a lot of mixed information out there. L-carnitine is among the more controversial supplements. While there is evidence it supports muscle recovery and enhances exercise performance, research has also shown it can contribute to cardiovascular disease.

    In a new study, my colleagues and I found it may be possible to counter the negative effects of l-cartinine by eating pomegranate with it.

    First, it’s important to understand what l-carnitine is. Your body produces a small amount of l-carnitine naturally. This happens in the kidneys, liver and brain.

    When l-carnitine was first identified in humans in 1952, it was thought to be a vitamin and it was referred to as vitamin BT. After years of research on this compound, l-carnitine is now considered a quasi-vitamin because for most people the human body can produce enough l-carnitine itself.

    L-carnitine can be bought as a dietary supplement, but the nutrient is also added to energy drinks and some protein powders by manufacturers to try and enhance the value of their products. Manufacturers normally clearly state it on the product if it contains l-carnitine – it’s not something a company will try to hide.

    Some foods naturally contain l-carnitine, such as meat and in tiny amounts in dairy products. L-carnitine is not fed to livestock but it is present in muscle tissue. L-carnitine was first found in meat in 1905. It is for this reason that the name carnitine is derived from the Latin word carnis, meaning “of the flesh”.

    L-carnitine is sold in sport supplements.

    The harmful effects of l-carnitine supplements

    It is not thought to be intrinsically harmful. Your gut microbes are to blame for the risks associated with l-carnitine.

    Less than 20% of l-carnitine supplements can be taken in by the human body. The unabsorbed l-carnitine travels down the gastrointestinal tract and reaches the colon. The colon is home to trillions of microbes, including bacteria, viruses and fungi.

    When the remaining 80% of the l-carnitine supplement arrives in the colon, the microbes start absorbing the nutrient and they use it to produce something else: trimethylamine (TMA). TMA is a compound the human body can efficiently absorb, and that is where the potentially harmful effects of l-carnitine supplements arise.

    Once the body absorbs TMA, it goes to the liver via the blood stream. The liver converts TMA to trimethylamine N-oxide (TMAO). Research has shown that high levels of TMAO in the blood can contribute to cardiovascular disease.

    For example, a research group at the Cleveland Clinic in the US gave human participants a nutrient similar to l-carnitine that is also converted into TMA by gut microbes. The researchers found that the nutrient caused an increased risk of thrombosis (blood clots) in their participants.

    L-carnitine itself is a beneficial nutrient. When it is produced by our bodies, which happens in the kidneys, brain and liver, it’s not metabolised by the gut microbiota and isn’t converted to TMAO. Your body can absorb more l-carnitine from meat than from supplements, which makes it less harmful as that means less of it ends up in the colon.

    Dietary intervention can reduce harmful effects

    In my team’s lab at the Quadram Institute in Norwich, England, we simulated what happens when the l-carnitine supplement reaches the microbes in the colon. We fed a culture of gut microbes with l-carnitine and measured the TMA that the microbes produced.

    Then, we fed a culture of gut microbes with l-carnitine together with a pomegranate extract, which is rich in polyphenols. Polyphenols are plant compounds with antioxidant, antimicrobial, and anti-inflammatory properties that may help keep you healthy and protect you against diseases.

    The main polyphenols in pomegranate belong to a group called ellagitannins, a type of polyphenol that can reach the colon almost entirely intact, where they can interact with the gut microbiota. When we measured the TMA that the gut microbes produced in the second experiment, we saw much less TMA.

    Our experiments in the lab show that a polyphenol-rich pomegranate extract can reduce microbial TMA production and eliminate the potentially harmful effects of l-carnitine supplements.

    Our laboratory experiments showed that the pomegranate extract can reduce the production of TMA. Ellagitannins are also abundant in other fruits and nuts, such as raspberries and walnuts. So, if you take l-carnitine supplements, our research suggests that it may be a good idea to include ellagitannin-rich foods in your diet. Eating more fruits and nuts can be good for your health, so including these in your diet will probably be beneficial anyway.

    Our group is now moving the science outside of the lab. We are testing in human participants how effective the pomegranate extract is at reducing TMAO production from l-carnitine supplements. This study will tell us whether taking an l-carnitine supplement along with a pomegranate extract may be better than taking the supplement on its own.

    Sport supplements are hard to get away from if you like to exercise regularly. Even if you’re not interested in them, there’s a good chance your gym will have posters extolling their virtues or your sporty friends will want to talk to you about them.

    It can be hard to know what supplements to take as there is a lot of mixed information out there. L-carnitine is among the more controversial supplements. While there is evidence it supports muscle recovery and enhances exercise performance, research has also shown it can contribute to cardiovascular disease.

    In a new study, my colleagues and I found it may be possible to counter the negative effects of l-cartinine by eating pomegranate with it.

    First, it’s important to understand what l-carnitine is. Your body produces a small amount of l-carnitine naturally. This happens in the kidneys, liver and brain.

    When l-carnitine was first identified in humans in 1952, it was thought to be a vitamin and it was referred to as vitamin BT. After years of research on this compound, l-carnitine is now considered a quasi-vitamin because for most people the human body can produce enough l-carnitine itself.

    L-carnitine can be bought as a dietary supplement, but the nutrient is also added to energy drinks and some protein powders by manufacturers to try and enhance the value of their products. Manufacturers normally clearly state it on the product if it contains l-carnitine – it’s not something a company will try to hide.

    Some foods naturally contain l-carnitine, such as meat and in tiny amounts in dairy products. L-carnitine is not fed to livestock but it is present in muscle tissue. L-carnitine was first found in meat in 1905. It is for this reason that the name carnitine is derived from the Latin word carnis, meaning “of the flesh”.

    The harmful effects of l-carnitine supplements

    It is not thought to be intrinsically harmful. Your gut microbes are to blame for the risks associated with l-carnitine.

    Less than 20% of l-carnitine supplements can be taken in by the human body. The unabsorbed l-carnitine travels down the gastrointestinal tract and reaches the colon. The colon is home to trillions of microbes, including bacteria, viruses and fungi.

    When the remaining 80% of the l-carnitine supplement arrives in the colon, the microbes start absorbing the nutrient and they use it to produce something else: trimethylamine (TMA). TMA is a compound the human body can efficiently absorb, and that is where the potentially harmful effects of l-carnitine supplements arise.

    Once the body absorbs TMA, it goes to the liver via the blood stream. The liver converts TMA to trimethylamine N-oxide (TMAO). Research has shown that high levels of TMAO in the blood can contribute to cardiovascular disease.

    For example, a research group at the Cleveland Clinic in the US gave human participants a nutrient similar to l-carnitine that is also converted into TMA by gut microbes. The researchers found that the nutrient caused an increased risk of thrombosis (blood clots) in their participants.

    L-carnitine itself is a beneficial nutrient. When it is produced by our bodies, which happens in the kidneys, brain and liver, it’s not metabolised by the gut microbiota and isn’t converted to TMAO. Your body can absorb more l-carnitine from meat than from supplements, which makes it less harmful as that means less of it ends up in the colon.

    Dietary intervention can reduce harmful effects

    In my team’s lab at the Quadram Institute in Norwich, England, we simulated what happens when the l-carnitine supplement reaches the microbes in the colon. We fed a culture of gut microbes with l-carnitine and measured the TMA that the microbes produced.

    Then, we fed a culture of gut microbes with l-carnitine together with a pomegranate extract, which is rich in polyphenols. Polyphenols are plant compounds with antioxidant, antimicrobial, and anti-inflammatory properties that may help keep you healthy and protect you against diseases.

    Our experiments in the lab show that a polyphenol-rich pomegranate extract can reduce microbial TMA production and eliminate the potentially harmful effects of l-carnitine supplements.

    Our laboratory experiments showed that the pomegranate extract can reduce the production of TMA. Ellagitannins are also abundant in other fruits and nuts, such as raspberries and walnuts.

    Ebenezer Scrooge tried to wave away the ghost of Jacob Marley by blaming the apparition on “an undigested bit of beef … a crumb of cheese”. Charles Dickens might have been writing fiction, but the idea that late-night dairy can warp dreams has now gained scientific support.

    Researchers in Canada surveyed 1,082 university students about their eating habits, sleep patterns and dreams.  Remarkably, 40% reported that certain foods affected their sleep. Of that group, 20% blamed dairy – suggesting that Scrooge’s midnight cheese might have had more of an impact than he realised.

    Just 5.5% believed food changed their dreams, but among those respondents dairy again loomed large, second only to sugary desserts as a perceived trigger for bizarre or disturbing dreams.

    The researchers asked about everything from nightmare frequency to food allergies and intolerances. A clear pattern emerged: participants who reported lactose intolerance were significantly more likely to have frequent nightmares. And the link was strongest in people who also experienced bloating or cramps.

    Statistical modelling suggested the stomach distress partly explains the bad dreams. In other words, food that keeps the gut churning can also set the imagination spinning.

    That gut–brain route makes physiological sense. Abdominal discomfort can jolt sleepers into lighter stages of sleep where vivid or negative dreams are most common. Inflammation and spikes in cortisol (a stress hormone) triggered by digestive upset may further shape the emotional tone of dreams, especially by amplifying anxiety or negativity.

    Earlier work backs the idea. A 2015 survey of Canadian undergraduates found that nearly 18% linked what they ate to their dreams, with dairy the top suspect, while a 2022 online study of 436 dream enthusiasts reported that people who ate more sugary snacks remembered more nightmares.

    The new study from Canada echoes a wider literature on diet and sleep. Diets rich in fibre, fruit and vegetables are associated with deeper, more refreshing sleep, whereas meals high in saturated fat and sugar predict lighter, more fragmented rest.

    Eating late in the evening has been tied to poorer sleep quality and to an “evening chronotype” (that is, night owls), itself linked to nightmare frequency.

    If future work confirms the cheese–nightmare connection, the implications could be practical. Nightmares affect about 4% of adults worldwide and are particularly common in post-traumatic stress disorder.

    Drug treatments exist but carry side-effects. Adjusting the timing or composition of evening meals, or choosing low-lactose dairy options, would be a far cheaper, lower-risk intervention.

    Gut-friendly diets such as the Mediterranean diet are already being explored for mood disorders; nightmares may be another frontier for nutritional psychiatry.

    What the research can’t prove

    That said, the new findings come with caveats. The sample was young, mostly healthy psychology students filling out online questionnaires. Food intake, lactose intolerance and nightmare frequency were all self-reported, so “recall biases” (inaccurate memory) or the power of suggestion could inflate the associations.

    Only 59 participants believed food influenced their dreams, so small-number effects (unreliable results from too few data) are possible. And a survey can only reveal associations – it can’t prove that cheese causes bad dream.

    Cheese keeps cropping up in nightmare stories, and people who struggle to digest dairy report the worst of it. Scientists still have to match meal diaries, gut clues and lab-monitored dreams to prove the link. In the meantime, try eating earlier or choosing low-lactose options. Your stomach – and your dreams – may calm down.

  • MIL-OSI Analysis: Trauma is carried in your DNA. But science reveals a more complicated story

    As war continues to rage in Gaza and Ukraine, there is concern about how the related trauma might be transmitted to future generations of people in those regions.

    More generally, interest in the idea of transgenerational trauma has recently surged. For example, earlier this year, National Geographic magazine asked whether genes carry past family trauma.

    But while this might be a catchy question, it’s also slightly misleading. Because while trauma can ripple across generations, shaped by how our bodies respond to their environments, its effects aren’t hard-coded in our genes.

    Plastic minds and bodies

    At the heart of this process is what’s known as phenotypic plasticity.

    This is the capacity for organisms to produce different outcomes from the same genes, depending on their environment. These outcomes, called phenotypes, can include stress sensitivity and body shape.

    One way different phenotypes can arise from the same genes is via epigenetics: small chemical changes to the DNA molecule that make particular genes more or less active. Think of these like a director’s notes on a script. These notes guide the cell on which lines to emphasise or soften, without changing the script itself.

    But epigenetics is just one way this plasticity is expressed.

    Understanding how trauma is passed across generations means looking beyond genes and cells to the environments that shape and influence them.

    Human development is sculpted by lived experience, from caregiving and community to stress, safety and belonging.

    These factors interact to produce lasting – but not always fixed – effects. By focusing on how they interact, rather than on single causes, we can better understand why trauma echoes across generations. This also helps us identify how that cycle might be disrupted.

    Widespread in nature

    Phenotypic plasticity is widespread in nature.

    In honeybees, genetically identical larvae become queens or workers depending on what they eat while developing. In three-spined stickleback fish, early exposure to predators reshapes their stress physiology and body shape, making them harder for predators to grasp.

    These aren’t genetic differences – they’re environmental effects on development.

    In humans, early-life conditions similarly shape development. A child raised in an unsafe setting may develop heightened vigilance or stress sensitivity – traits that help in danger but can persist as anxiety or chronic stress in times of safety. This is known as environmental mismatch.

    Across generations, plasticity becomes more complicated. In some of my past research, I studied how diet in one generation of fruit flies shaped health, reproduction and longevity in their offspring and grand offspring.

    The results varied depending on diet, generation and trait. Traits that appeared to be useful in one generation weren’t always so in the next. This highlights how difficult transgenerational effects are to predict – precisely because of this plasticity.

    Too narrow an explanation

    Epigenetics often reflect environmental exposures – such as stress, trauma, nutrition or caregiving. But they’re not necessarily permanent “scars”. Many are dynamic and can shift with changing environments – especially early in life.

    Studies show that epigenetic patterns linked to early childhood adversity vary depending on later environments such as family stability and social support. This suggests the biological imprint of early stress is shaped by what happens next.

    It’s tempting to treat epigenetics as the key to explaining inherited trauma – but that’s too narrow. Trauma can influence the next generation through altered hormones, immune function or in utero conditions – all of which shape brain development and stress reactivity.

    Genetic variation also plays a major role. It doesn’t encode trauma itself, but it shapes traits such as sensitivity to threat or emotional regulation. These traits aren’t chosen – they arise from a web of biological and social influences beyond our control.

    But how they unfold, and whether they’re amplified or softened, depends on the systems that surround us.

    Connection to culture

    Connection to culture plays an important role too.

    In Aotearoa New Zealand, Māori-led initiatives that centre land, language and whakapapa (ancestral lineage) have shown promise in restoring wellbeing after generations of colonisation-related trauma.

    For Holocaust survivors and descendants, connection to cultural identity through ritual and shared narrative can reduce the psychological burden of transmitted trauma.

    But not all trauma is collective or institutional. Interventions such as trauma-informed parenting and early relational therapies have been shown to improve outcomes in the next generation.

    These psychological supports affect biology. Feeling safe in our relationships, having stable routines and a sense of meaning can reduce stress hormones, modulate immune function, and buffer against long-term disease risk.

    In this way, culture, caregiving and connection are all biological interventions. When they soften the effects of earlier stress, they may help interrupt its transmission.

    Trauma-informed parenting has been shown to improve outcomes in the next generation.

    Reframing inherited vulnerability

    This matters, because it changes how we understand inherited vulnerability.

    Rather than a permanent wound passed down through DNA, the effects of trauma are better understood as changeable responses shaped by context.

    Thanks to plasticity, our biology is always in conversation with the environment – and when we change the context, we can change the outcome.

    MIL OSI Analysis –

  • MIL-OSI Analysis: Around 250 million years ago, Earth was near-lifeless and locked in a hothouse state. Now scientists know why

    Source: The Conversation – Global Perspectives – By Andrew Merdith, DECRA Fellow, School of Earth Sciences, University of Adelaide

    Some 252 million years ago, almost all life on Earth disappeared.

    Known as the Permian–Triassic mass extinction – or the Great Dying – this was the most catastrophic of the five mass extinction events recognised in the past 539 million years of our planet’s history.

    Up to 94% of marine species and 70% of terrestrial vertebrate families were wiped out. Tropical forests – which served, as they do today, as important carbon sinks that helped regulate the planet’s temperature – also experienced massive declines.

    Scientists have long agreed this event was triggered by a sudden surge in greenhouse gases which resulted in an intense and rapid warming of Earth. But what has remained a mystery is why these extremely hot conditions persisted for millions of years.

    Our new paper, published today in Nature Communications, provides an answer. The decline of tropical forests locked Earth in a hothouse state, confirming scientists’ suspicion that when our planet’s climate crosses certain “tipping points”, truly catastrophic ecological collapse can follow.

    A massive eruption

    The trigger for the Permian–Triassic mass extinction event was the eruption of massive amounts of molten rock in modern day Siberia, named the Siberian Traps. This molten rock erupted in a sedimentary basin, rich in organic matter.

    The molten rock was hot enough to melt the surrounding rocks and release massive amounts of carbon dioxide into Earth’s atmosphere over a period as short as 50,000 years but possibly as long as 500,000 years. This rapid increase in carbon dioxide in Earth’s atmosphere and the resulting temperature increase is thought to be the primary kill mechanism for much of life at the time.

    On land it is thought surface temperatures increased by as much as 6°C to 10°C – too rapid for many life forms to evolve and adapt. In other similar eruptions, the climate system usually returns to its previous state within 100,000 to a million years.

    But these “super greenhouse” conditions, which resulted in equatorial average surface temperatures upwards of 34°C (roughly 8°C warmer than the current equatorial average temperature) persisted for roughly five million years. In our study we sought to answer why.

    The forests die out

    We looked at the fossil record of a wide range of land plant biomes, such as arid, tropical, subtropical, temperate and scrub. We analysed how the biomes changed from just before the mass extinction event, until about eight million years after.

    We hypothesised that Earth warmed too rapidly, leading to the dying out of low- to mid-latitude vegetation, especially the rainforests. As a result the efficiency of the organic carbon cycle was greatly reduced immediately after the volcanic eruptions.

    Plants, because they are unable to simply get up and move, were very strongly affected by the changing conditions.

    Before the event, many peat bogs and tropical and subtropical forests existed around the equator and soaked up carbon

    However, when we reconstructed plant fossils from fieldwork, records and databases around the event we saw that these biomes were completely wiped out from the tropical continents. This led to a multimillion year “coal gap” in the geological record.

    These forests were replaced by tiny lycopods, only two to 20 centimetres in height.

    Enclaves of larger plants remained towards the poles, in coastal and in slightly mountainous regions where the temperature was slightly cooler. After about five million years they had mostly recolonised Earth. However these types of plants were also less efficient at fixing carbon in the organic carbon cycle.

    This is analogous in some ways to considering the impact of replacing all rainforests at present day with the mallee-scrub and spinifex flora that we might expect to see in the Australian outback.

    Post-extinction lycopod fossils.
    Zhen Xu

    Finally, the forests return

    Using evidence from the present day, we estimated the rate at which plants take atmospheric carbon dioxide and store it as organic matter of each different biome (or its “net primary productivity”) that was suggested in the fossil record.

    We then used a recently developed carbon cycle model called SCION to test our hypothesis numerically. When we analysed our model results we found that the initial increase in temperature from the Siberian Traps was preserved for five to six million years after the event because of the reduction in net primary productivity.

    It was only as plants re-established themselves and the organic carbon cycle restarted that Earth slowly started to ease out of the super greenhouse conditions.

    Maintaining a climate equilibrium

    It’s always difficult to draw analogies between past climate change in the geological record and what we’re experiencing today. That’s because the extent of past changes is usually measured over tens to hundreds of thousands of years while at present day we are experiencing change over decades to centuries.

    A key implication of our work, however, is that life on Earth, while resilient, is unable to respond to massive changes on short time scales without drastic rewirings of the biotic landscape.

    In the case of the Permian–Triassic mass extinction, plants were unable to respond on as rapid a time scale as 1,000 to 10,000 years. This resulted in a large extinction event.

    Overall, our results underline how important tropical and subtropical plant biomes and environments are to maintaining a climate equilibrium. In turn, they show how the loss of these biomes can contribute to additional climate warming – and serve as a devastating climate tipping point.

  • MIL-OSI Analysis: Trump wins again as ‘big beautiful bill’ passes the Senate. What are the lessons for the Democrats?

    Source: The Conversation – Global Perspectives – By Dafydd Townley, Teaching Fellow in US politics and international security, University of Portsmouth

    Donald Trump is continuing his run of political wins after his keynote legislation, nicknamed the ‘big beautiful bill’, squeaked through the Senate.

    While the bill, which includes major cuts in tax and government spending, must now go back to the House of Representatives for another vote, passing the upper house is highly significant. Trump lost the support of just three Republican senators, and with the help of a tie-breaking vote from Vice-President J.D. Vance managed to push the bill forward.

    Democrats, the minority in both the House and Senate, have been unable to do anything but sit by and watch as Trump claims victory after victory. These include progress in his attempt to end birthright citizenship, the claimed destruction of significant Iranian nuclear sites (yet to be independently verified) and the convincing of Nato member states to increase defence spending to 5% of their GDP. Trump may even be getting closer to a peace deal between Israel and Hamas.

    And now the Democrats have failed in their desperate attempts to stop this bill. In the Senate, it was felt that there could be enough Republican senators concerned about cuts to Medicaid (the US system that provides essential healthcare to those on low incomes), the closure or reduction of services at rural hospitals, and the increase in national debt to potentially hinder the bill’s progress. However, Democrats were unable to do anything apart from delaying the voting process, and the bill is progressing with some changes but not enough to be severely weakened.

    It had seemed likely that the Democrats could work with the Maga-focused Freedom Caucus group of representatives, whose members include Marjorie Taylor Greene, in the early stages in the House to stop its initial passage. But Speaker Mike Johnson managed to calm most of their fears about the rise in the deficit to get the bill through the House.

    The lack of effective opposition from the Democrats reflects their congressional standing. The Republicans control the Senate 53-47, and they also have a majority of 220-212 in the House, with three vacancies.

    While Democrat numbers in Congress is the primary issue in opposing this bill, their future congressional power will rely on strong leadership within the party and, more importantly, a clear set of policies with appeal that can attract more support at the ballot boxes. Failure to address this will probably allow Republicans to dominate Congress and shape American domestic and foreign policy any way they wish for longer.

    Trump’s agenda has now passed the Senate.

    What could Democrats do differently?

    While Democrat Hakeem Jeffries has been a diligent minority leader in the House, he has attempted to operate as an obstacle to Republican policies with little success, rather than reaching across the political divide to create a consensus with dissenting Republicans.

    Outside of Congress, California governor Gavin Newsom, widely touted as a potential candidate for the next presidential election, has offered some resistance to the Trump administration, particularly over Trump’s assumption of national command over the state-controlled National Guard to deal with protests in California against the Immigration and Customs Enforcement agency. However, Newsom’s reputation is still relatively regional, although it is on the rise.

    Zohran Mamdani has won the Democratic nomination for New York mayor.

    There will be jostling over the next couple of years for the Democratic presidential nomination, and this will have an impact on the platform that the party runs on. Party members and those voting for the next presidential nominee will need to decide whether to continue with the mainly centrist position that the party has adopted since the 1990s or adopt something more left-wing.

    A more radical candidate, such as New York representative Alexandria Ocasio-Cortez, might offer a substantially different proposal that could seem attractive to Democratic voters and those Trump supporters who may feel dissatisfied with the current Republican administration.

    However, democratic socialist Zohran Mamdani, recently selected as the Democratic nominee for the New York mayoral election, has already been vilified by some in the Republican party.

    Concerns about such a supposedly “radical” candidate may concern many voters in red states in middle America. However, getting elected is one thing but implementing progressive, left-leaning policies is another thing entirely. They also need to deliver solutions to major issues, such as crime, at all levels, to show their abilities to solve problems.

    It is not just the policies that matter for the Democrats, but who they want to represent. Last year’s election suggested that the Democrats had been ousted as the representatives of the working class. Some significant labour unions, a foundation of Democratic support for the majority of the 20th century, failed to endorse Kamala Harris.

    Mamdani’s success in New York stemmed from the mobilisation of a grassroots campaign that used social media effectively. It targeted young working-class voters disenchanted with the Democratic party. He also resonated with voters in areas that had seen an increase in Republican voters in the 2024 election.

    All this may offer some lessons to the Democrats. They need to reassess their policies, their image and their tactics, and show Americans that they can solve the problems that the public sees as most important, including the high cost of living. While they can expect to gain seats in the House in next year’s midterms, they need to look for a leader and policies that will capture the public’s hearts.

  • MIL-OSI Analysis: More and more tourists are flocking to Antarctica. Let’s stop it from being loved to death

    The number of tourists heading to Antarctica has been skyrocketing. From fewer than 8,000 a year about three decades ago, nearly 125,000 tourists flocked to the icy continent in 2023–24. The trend is likely to continue in the long term.

    Unchecked tourism growth in Antarctica risks undermining the very environment that draws visitors. This would be bad for operators and tourists. It would also be bad for Antarctica – and the planet.

    Over the past two weeks, the nations that decide what human activities are permitted in Antarctica have convened in Italy. The meeting incorporates discussions by a special working group that aims to address tourism issues.

    It’s not easy to manage tourist visitors to a continent beyond any one country’s control. So, how do we stop Antarctica being loved to death? The answer may lie in economics.

    Future visitor trends

    We recently modelled future visitor trends in Antarctica. A conservative scenario shows by 2033–34, visitor numbers could reach around 285,000. Under the least conservative scenario, numbers could reach 450,000 – however, this figure incorporates pent-up demand from COVID shutdowns that will likely diminish.

    The vast majority of the Antarctic tourism industry comprises cruise-ship tourism in the Antarctic Peninsula. A small percentage of visitors travel to the Ross Sea region and parts of the continent’s interior.

    Antarctic tourism is managed by an international set of agreements together known as the Antarctic Treaty System, as well as the International Association of Antarctica Tour Operators (IAATO).

    The Treaty System is notoriously slow-moving and riven by geopolitics, and IAATO does not have the power to cap visitor numbers.

    Pressure on a fragile continent

    About two-thirds of Antarctic tourists land on the continent. The visitors can threaten fragile ecosystems by:

    • compacting soils
    • trampling fragile vegetation
    • introducing non-native microbes and plant species
    • disturbing breeding colonies of birds and seals.

    Even when cruise ships don’t dock, they can cause problems such as air, water and noise pollution – as well as anchoring that can damage the seabed.

    Then there’s carbon emissions. Each cruise ship traveller to Antarctica typically produces between 3.2 and 4.1 tonnes of carbon, not including travel to the port of departure. This is similar to the carbon emissions an average person produces in a year.

    Global warming caused by carbon emissions is damaging Antarctica. At the Peninsula region, glaciers and ice shelves are retreating and sea ice is shrinking, affecting wildlife and vegetation.

    Of course, Antarctic tourism represents only a tiny fraction of overall emissions. However, the industry has a moral obligation to protect the place that maintains it. And tourism in Antarctica can compound damage from climate change, tipping delicate ecosystems into decline.

    Some operators use hybrid ships and less polluting fuels, and offset emissions to offer carbon-neutral travel.

    IAATO has pledged to halve emissions by 2050 – a positive step, but far short of the net-zero targets set by the International Maritime Organization.

    Can economics protect Antarctica?

    Market-based tools – such as taxes, cap-and-trade schemes and certification – have been used in environmental management around the world. Research shows these tools could also prevent Antarctic tourist numbers from getting out of control.

    One option is requiring visitors to pay a tourism tax. This would help raise revenue to support environmental monitoring and enforcement in Antarctica, as well as fund research.

    Such a tax already exists in the small South Asian nation of Bhutan, where each tourist pays a tax of US$100 (A$152) a night. But while a tax might deter the budget-conscious, it probably wouldn’t deter high income, experience-driven tourists.

    Alternatively, a cap-and-trade system would create a limited number of Antarctica visitor permits for a fixed period. The initial distribution of permits could be among tourism operators or countries, via negotiation, auction or lottery. Unused permits could then be sold, making them quite valuable.

    Caps have been successful at managing tourism impacts elsewhere, such as Lord Howe Island, although there are no trades allowed in that system.

    Any cap on tourist numbers in Antarctica, and rules for trading, must be based on evidence about what the environment can handle. But there is a lack of precise data on Antarctica’s carrying capacity. And permit allocations amongst the operators and nations would need to be fair and inclusive.

    Alternatively, existing industry standards could be augmented with independent schemes certifying particular practices – for example, reducing carbon footprints. This could be backed by robust monitoring and enforcement to avoid greenwashing.

    Looking ahead

    Given the complexities of Antarctic governance, our research finds that the most workable solution is a combination of these market-based options, alongside other regulatory measures.

    So far, parties to the Antarctic treaty have made very few binding rules for the tourism industry. And some market-based levers will be more acceptable to the parties than others. But doing nothing is not a solution.

  • MIL-OSI Analysis: Thumbs up: good or passive aggressive? How emojis became the most confusing kind of online language

    Source: The Conversation – Global Perspectives – By Brittany Ferdinands, Lecturer in Digital Content Creation, Discipline of Media and Communications, University of Sydney

    The Conversation, CC BY

    Emojis, as well as memes and other forms of short-form content, have become central to how we express ourselves and connect online. Yet as meanings shift across different contexts, so too does the potential for misunderstanding.

    A senior colleague of mine recently encountered some commentary about the “slightly smiling” face emoji: 🙂

    They approached me, asking whether it represented joy, as they had assumed, or if it had a more ominous meaning.

    As a chronically-online millennial, who unironically identifies as a gen Z, I bore the news that I, along with most younger internet users, only ever use it sarcastically.

    “It doesn’t actually signify happiness – more so fake happiness, or dry humour,” I explained.

    I also told them how the thumbs up emoji is often interpreted as passive aggressive, and that the only time I’d use the laughing-crying (“face with tears of joy”) emoji is under duress.

    Despite seeming like a universal language – and sometimes they do function that way – emojis can be at once more vague, and more specific, than words. That’s because you can’t separate the meaning of a smiley from the person who sent it, nor from the person receiving it.

    Markers of age and identity

    While emojis were originally developed in the late 1990s by Japanese artist Shigetaka Kurita to add emotional nuance to text-based messaging, their function has since evolved.

    Today, emojis are not just emotional cues; they also operate as cultural symbols and markers of identity.

    Research published last year highlights how these symbols can create subtle communication barriers across age groups. For instance, a study of Chinese-speaking WeChat users found younger and older people differed not only in how frequently they used emojis, but in how they interpreted and aesthetically preferred them.

    One emoji that’s increasingly becoming a distinct marker of age is the previously mentioned laughing-crying emoji (😂). Despite being named Oxford Dictionary’s 2015 word of the year, and frequently topping the most-used emoji charts, this smiley is on the decline among gen Z – who decided in 2020 that it wasn’t cool anymore.

    Instead, they prefer the skull emoji (💀), which is shorthand for the gen Z catch phrase “I’m dead”. This means something is funny (not that they’re literally deceased).

    Such shifts may understandably be perplexing for older generations who are unfamiliar with evolving norms and slang.

    A digital body language

    Emojis can also take on distinct meanings on different platforms. They are embedded within “platform vernaculars”: the ever-evolving styles of communication that are unique to specific digital spaces.

    For example, a thumbs up emoji (👍) from your boss at work is seemingly more acceptable, and less anxiety inducing, than from a romantic interest you’ve just sent a risky text to.

    This dilemma was echoed in a recent viral TikTok by user @kaitlynghull, which prompted thousands to comment about their shared confusion over emoji use in the workplace.

    This reaction highlights a deeper communication issue.

    A survey of 10,000 workers across the US, France, Germany, India and Australia, conducted by YouGov and software company Atlassian, found 65% of workers used emojis to convey tone in the workplace. But while 88% of gen Z workers thought emojis were helpful, this dropped to 49% for baby boomers and gen X.

    The survey concluded some emojis can be interpreted in multiple ways, and these double meanings aren’t always safe for work.

    In with the ‘it’ crowd

    Another example of platform-specific emoji use comes from social media content creators who deploy emojis to curate a certain aesthetic.

    Under the Tiktok tag #emojicombo, you’ll find thousands of videos showcasing emoji combinations that provide aesthetic “inspo”. These combinations are used to represent different online identities or subcultures, such as “that girl”, “clean girl” or “old money”.

    Users may include the combinations in their captions or videos to signal their personal style, or to express the mood or vibe of their online persona. In this way, the emojis help shape how they present themselves on the platform.

    This example of emoji use is also a display of symbolic capital. It signals social alignment, in an environment where a user’s visibility (and popularity) is determined by their platform fluency.

    Emojis, then, aren’t just tools for expression. They are badges of identity that index where a user stands in the online cultural hierarchy.

    There’s a fragmentation in how we relate

    A single emoji might communicate irony, sincerity or sarcasm, depending on who is using it, what platform they’re using it on, and what generation they belong to.

    This gap points to deeper questions around online access and participation, and the systems that shape online cultures.

    And when the meaning of an emoji is platform-dependent and socially stratified, it can become as much about fitting in with a cultural in-group than conveying emotion.

  • MIL-OSI Analysis: Trump is not like other presidents – but can he beat the ‘second term curse’ that haunts the White House?

    Source: The Conversation – Global Perspectives – By Garritt C. Van Dyk, Senior Lecturer in History, University of Waikato

    While he likes to provoke opponents with the possibility of serving a third term, Donald Trump faces a more immediate historical burden that has plagued so many presidents: the “second term curse”.

    Twenty-one US presidents have served second terms, but none has reached the same level of success they achieved in their first.

    Second term performances have ranged from the lacklustre and uninspiring to the disastrous and deadly. Voter dissatisfaction and frustration, presidential fatigue and a lack of sustainable vision for the future are all explanations.

    But Trump doesn’t quite fit the mould. Only one other president, Grover Cleveland in the late 19th century, has served a second nonconsecutive term, making Trump 2.0 difficult to measure against other second-term leaders.

    Trump will certainly be hoping history doesn’t repeat Cleveland’s second-term curse. Shortly after taking office he imposed 50% tariffs, triggering global market volatility that culminated in the “Panic of 1893”.

    At the time, this was the worst depression in US history: 19% unemployment, a run on gold from the US Treasury, a stock market crash and widespread poverty.

    More than a century on, Trump’s “move fast and break things” approach in a nonconsecutive second term might appeal to voters demanding action above all else. But he risks being drawn into areas he campaigned against.

    So far, he has gone from fighting a trade war and a culture war to contemplating a shooting war in the Middle East. His “big beautiful bill” will add trillions to the national debt and potentially force poorer voters – including many Republicans – off Medicaid.

    Whether his radical approach will defy or conform to the second term curse seems very much an open question.

    No kings

    The two-term limit was enacted by the 22nd Amendment to the Constitution in 1951. Without a maximum term, it was feared, an authoritarian could try to take control for life – like a king (hence the recent “No Kings” protests in the US).

    George Washington, James Madison and Thomas Jefferson all declined to serve a third term. Jefferson was suspicious of any president who would try to be re-elected a third time, writing:

    should a President consent to be a candidate for a 3d. election, I trust he would be rejected on this demonstration of ambitious views.

    There is a myth that after Franklin Delano Roosevelt broke the de facto limit of two terms set by the early presidents, the ghost of George Washington placed a curse on anyone serving more than four years.

    At best, second-term presidencies have been tepid compared to the achievements in the previous four years. After the second world war, some two-term presidents (Eisenhower, Reagan and Obama) started out strong but faltered after reelection.

    Eisenhower extricated the US from the Korean War in his first term, but faced domestic backlash and race riots in his second. He had to send 500 paratroopers to escort nine Black high school students in Little Rock, Arkansas, to enforce a federal desegregation order.

    Reagan made significant tax and spending cuts, and saw the Soviet Union crumble in term one. But the Iran-Contra scandal and watered down tax reform defined term two.

    Obama started strongly, introducing health care reform and uniting the Democratic voter base. After reelection, however, the Democrats lost the House, the Senate, a Supreme Court nomination, and faced scandals over the Snowden security leaks and Internal Revenue Service targeting of conservative groups.

    Truly disastrous examples of second term presidencies include Abraham Lincoln (assassination), Woodrow Wilson (first world war, failure of the League of Nations, a stroke), Richard Nixon (Watergate, impeachment and resignation), and Bill Clinton (Lewinsky scandal and impeachment).

    Room for one more? Trump has joked about being added to Mount Rushmore.

    Monumental honours

    It may be too early to predict how Trump will feature in this pantheon of less-than-greatness. But his approval ratings recently hit an all-time low as Americans reacted to the bombing of Iran and deployment of troops in Los Angeles.

    A recent YouGov poll showed voters giving negative approval ratings for his handling of inflation, jobs, immigration, national security and foreign policy. While there has been plenty of action, it may be the levels of uncertainty, drastic change and market volatility are more extreme than some bargained for.

    An uncooperative Congress or opposition from the judiciary can be obstacles to successful second terms. But Trump has used executive orders, on the grounds of confronting “national emergencies”, to bypass normal checks and balances.

    As well, favourable rulings by the Supreme Court have edged closer to expanding the boundaries of executive power. But they have not yet supported Trump’s claim from his first term that “I have an Article 2, where I have the right to do whatever I want as President”.

    Some supporters say Trump deserves a Nobel Peace Prize. And he was only half joking when he asked if there is room for one more face on Mount Rushmore. But such monumental honours may only amount to speculation unless Trump’s radical approach and redefinition of executive power defy the second-term curse.

  • MIL-OSI Analysis: The Dalai Lama is a cisgender man – yet he has an unexpected connection to the trans community

    Source: The Conversation – Global Perspectives – By Stephen Kerry, Lecturer in Sociology, Charles Darwin University

    Tenzin Gyatso, the 14th Dalai Lama, turns 90 this week – a milestone that’s reigniting speculation over his eventual successor.

    While the Dalai Lama is the face of Buddhism to many people across the world, he is actually the head of just one tradition within Tibetan Buddhism known as the Gelug school.

    Tibetans believe the Dalai Lama to be the manifestation of Avalokiteśvara, the bodhisattva of compassion, and the “one who hears the cries of the world”.

    What is a bodhisattva? A scholar of Buddhism explains

    Avalokiteśvara is prayed to across Asia, and is known as Chenrezig in Tibet, Guanyin in China, and Kannon or Kanzeon in Japan.

    In Buddhism, a bodhisattva is a person, or a mythic representation of a person, who denies themselves enlightenment until all beings can achieve enlightenment. Avalokiteśvara appears to living beings in whatever form could best save them.

    Although Avalokiteśvara originated in India as a man, they can be depicted as either a man, woman, or non-binary being. This gender fluidity has led to them being revered as a trans icon in the West.

    I have spent the past five years investigating the lives of queer Buddhists in Australia. As part of this research, I have surveyed and interviewed 109 LGBTQIA+ Buddhist Australians.

    The words of these individuals, and my own experience as a genderqueer Buddhist person, reveal how the Dalai Lama emerges an an unlikely inspiration for individuals sharing a trans and Buddhist identity.

    Letting go of binaries

    Through my work I have found LGBTQIA+ Buddhist Australians are generally reluctant to disclose their queer identities to their Buddhist communities, and may be told to remain silent about their identities.

    For some, Avalokiteśvara’s gender fluidity has been important for reaffirming both their queer and Buddhist selves.

    One Buddhist trans woman, Annie*, told me Guanyin had special significance for her. Annie spoke about Avalokiteśvara travelling from India to China as a male, before “transitioning” to the mainly female presentation of Guanyin over centuries. Annie said:

    I pray to her regularly and often find I get a response. Of course the enlightened state is beyond all manner of worldly binaries, including gender, and is immensely important in letting go of binaries in my journey towards enlightenment.

    Walter* has had a long fascination with depictions of Avalokiteśvara that “showed ‘him’ looking effeminate and handsome, with a cute moustache […] A little bit homoerotic, a little bit provocatively gender fluid, as seen through my eyes”.

    Walter adds:

    A great many people in different cultures, across history, worship these figures. Clever how this figure can morph into a radical trans! We all want to feel comforted, safe and saved from suffering.

    As queer Buddhists, we turn to to Avalokitesvara to feel “comforted, safe and saved”.

    Another interviewee, Brian*, told me about a Tibetan invocation practice he did with a senior Tibetan monk, in which he encountered Guanyin:

    [She] took my right hand and passed some sort of power into it. She never spoke to me but just returned the way she had come. I was given some sort of gift, that’s all I know.

    Since this experience, Brian has “always felt a strong connection to the feminine through her”. He has a special Guanyin altar on his farm.

    You can’t be what you can’t see

    Some Buddhists deny Avalokiteśvara’s queerness.

    Asher*, a genderqueer Buddhist I interviewed, told me about a teacher who said to them, “there was absolutely no way a gay person could be enlightened”.

    Asher retorted:

    What about Kanzeon, the bodhisattva of compassion, who has manifested as both male and female and, in the stories from Japan, has had erotic relationships with monks?

    The teacher dismissed this, replying, “those are just stories”.

    In her 1996 book Transgender Warriors, trans activist Leslie Feinberg writes: “I couldn’t find myself in history. No one like me seemed to have ever existed.”

    Similarly, Annie evoked the statement: “You can’t be what you can’t see.”

    I, too, experience this need to see myself as a genderqueer, non-binary practitioner of Zen Buddhism. It was only through doing these interviews with other queer Buddhists that I came to realise Guanyin, a trans icon, is a statuette which adorns the altar of the Buddhist group I belong to.

    Knowing Avalokitesvara may be depicted as a man, woman, or non-binary being lets us queer Buddhists know we exist – and have always existed – within Buddhism.

    Despite being a cisgender man who has been somewhat inconsistent in his support of queer people, the Dalai Lama, as the manifestation of the bodhisattva of compassion, is a possible spiritual link between today’s queer Buddhists and centuries-long traditions of gender transition and fluidity.

  • MIL-OSI Analysis: Too much vitamin B6 can be toxic. 3 symptoms to watch out for

    Source: The Conversation – Global Perspectives – By Nial Wheate, Professor, School of Natural Sciences, Macquarie University

    Selena3726/Shutterstock

    Side effects from taking too much vitamin B6 – including nerve damage – may be more widespread than we think, Australia’s medicines regulator says.

    In an ABC report earlier this week, a spokesperson for the Therapeutic Goods Administration (TGA) says it may have underestimated the extent of the side effects from vitamin B6 supplements.

    However, there are proposals to limit sales of high-dose versions due to safety concerns.

    A pathologist who runs a clinic that tests vitamin B6 in blood samples from across Australia also appeared on the program. He told the ABC that data from May suggests 4.5% of samples tested had returned results “very likely” indicating nerve damage.

    So what are vitamin B6 supplements? How can they be toxic? And which symptoms do you need to watch out for?

    What is vitamin B6?

    Vitamin B6, also known as pyridoxine, plays an important role in keeping the body healthy. It is involved in the metabolism of proteins, carbohydrates and fats in food. It is also important for the production of neurotransmitters – chemical messengers in the brain that maintain its function and regulate your mood.

    Vitamin B6 also supports the immune system by helping to make antibodies, which fight off infections. And it is needed to produce haemoglobin, the protein in red blood cells that carries oxygen around the body.

    Some women take a vitamin B6 supplement when pregnant. It is thought this helps reduce the nausea associated with the early stages of pregnancy. Some women also take it to help with premenstrual syndrome.

    However, most people don’t need, and won’t benefit from, a vitamin B6 supplement. That’s because you get enough vitamin B6 from your diet through meat, breakfast cereal, fruit and vegetables.

    You don’t need much. A dose of 1.3–1.7 milligrams a day is enough for most adults.

    Currently, vitamin B6 supplements with a daily dose of 5–200mg can be sold over the counter at health food stores, supermarkets and pharmacies.

    Because of safety concerns, the TGA is proposing limiting their sale to pharmacies, and only after consultation with a pharmacist.

    Daily doses higher than 200mg already need a doctor’s prescription. So under the proposal that would stay the same.

    What happens if you take too much?

    If you take too much vitamin B6, in most cases the excess will be excreted in your urine and most people won’t experience side effects. But there is a growing concern about long-time, high-dose use.

    A side effect the medical community is worried about is peripheral neuropathy – where there is damage to the nerves outside the brain and spinal cord. This results in pain, numbness or weakness, usually in your hands and feet. We don’t yet know exactly how this happens.

    In most reported cases, these symptoms disappear once you stop taking the supplement. But for some people it may take three months to two years before they feel completely better.

    There is growing, but sometimes contradictory, evidence that high doses (more than 50mg a day) for extended periods can result in serious side effects.

    A study from the 1990s followed 70 patients for five years who took a dose of 100 to 150mg a day. There were no reported cases of neuropathy.

    But more recent studies show high rates of side effects.

    A 2023 case report provides details of a man who was taking multiple supplements. This resulted in a daily combined 95mg dose of vitamin B6, and he experienced neuropathy.

    Another report describes seven cases of neuropathy linked to drinking energy drinks containing vitamin B6.

    Reports to the TGA’s database of adverse events notifications (a record of reported side effects) shows 174 cases of neuropathy linked with vitamin B6 use since 2023.

    What should I do if I take vitamin B6?

    The current advice is that someone who takes a dose of 50mg a day or more, for more than six months, should be monitored by a health-care professional. So if you regularly take vitamin B6 supplements you should discuss continued use with your doctor or pharmacist.

    There are three side effects to watch out for, the first two related to neuropathy:

    1. numbness or pain in the feet and hands

    2. difficulty with balance and coordination as a result of muscle weakness

    3. heartburn and nausea.

    If you have worrying side effects after taking vitamin B6 supplements, contact your state’s poison information centre on 13 11 26 for advice.

  • MIL-OSI Analysis: How Europe dropped the ball on its own defence and was left fawning over Donald Trump – podcast

    Source: The Conversation – Global Perspectives – By Gemma Ware, Host, The Conversation Weekly Podcast, The Conversation

    The language from European leaders was fawning and obsequious. At one point, the head of Nato, Mark Rutte, even called Donald Trump “daddy”. But when the US president left the Nato summit in late June, there was a sigh of relief that he had not made any more angry criticism of the alliance.

    After months of American pressure, Nato members – with the exception of Spain – agreed to increase their spending on defence to 5% of GDP by 2035. Trump called it “very big news”, and even reconfirmed his commitment to Nato’s article 5, which means an attack on one Nato country is an attack on them all.

     How did Europe become so unable to defend itself that it was forced to resort to outright flattery of an American president?

    In this episode of The Conversation Weekly podcast, we report from the recent Siena Conference on the Europe of the Future in Italy about how the EU dropped the ball on its own defence and what its options are now.

     The European Commission, the executive branch of EU government, only appointed its first commissioner for defence in December 2024. There is no EU army, and no consensus as to whether democratic nations could ever allow one to be built.

    But in the period after the second world war, ambitions for a united European defence policy were much grander, as Ana Juncos Garcia, professor of European politics at the University of Bristol in the UK, explains:

    There was this idea to establish a European Defence Community which would pool competencies at the national level in defence to the European level, creating a supranational organisation with its own minister of defence, its own military committee.

    That failed in 1954 when the French national assembly rejected ratification of the treaty and progress on a pan-European defence strategy stalled. Nato, founded in 1949, became the core military alliance organising Europe’s defence, with the US as its main guarantor.

    Ever since, the EU has tried to balance the need for maintaining that transatlantic relationship, and figuring out a way to organise, and procure, its own defence capabilities in a joined up way.

  • MIL-OSI Analysis: How the myth of ‘Blitz spirit’ defined and divided London after 7/7

    Source: The Conversation – UK – By Darren Kelsey, Reader in Media and Collective Psychology, Newcastle University

    The “Blitz spirit” is one of Britain’s most enduring national myths – the stories we tell ourselves about who we were, and who we still believe we are today. Growing up among football fans, I heard constant nostalgic refrains about England and Germany, wartime bravery and national pride.

    Chants about “two world wars and one World Cup” or “ten German bombers in the air” were cultural rituals, flexes of a shared memory that many had never experienced themselves.

    Blitz spirit refers to the resilience, unity and stoic determination of civilians during the German bombing raids (the Blitz) of the second world war. It has reemerged time and again, symbolising a collective pride in facing adversity with courage, humour and a “keep calm and carry on” attitude.

    After the July 7 bombings in 2005, which killed 52 people and injured more than 700, I noticed how quickly the Blitz spirit reappeared. British newspapers reached into the past and pulled the myth forward.

    The Independent on July 8 said, “London can take it, and it can do so because its stoicism is laced as it always has been with humour.” The Daily Mail evoked images of “London during the Blitz… with everyone dancing through the bombs”.

    Tony Parsons opened his Daily Mirror column with “07/07 war on Britain: We can take it; if these murderous bastards go on for a thousand years, the people of our islands will never be cowed”, alongside an image of St Paul’s Cathedral during the Blitz.

    The spirit of working-class wartime London was, ironically, even applied to bankers and City traders who “kept the economy alive” after the attacks. A July 8 Times article claimed: “A Dunkirk spirit spread through London’s financial districts as Canary Wharf and City workers vowed they would not be deterred.”

    The use of river transport to evacuate workers reinforced the analogy. The Times described how “bankers and lawyers in London’s riverside Canary Wharf complex experienced their own version of the Dunkirk-style evacuations”, assisted by a “flotilla of leisure vessels and little ships”.

    I was fascinated: why this story, and why now? That question became the heart of a book I published in 2015 – one that explored how a myth born in 1940 was reborn in 2005, repurposed for a very different London.

    What I found was that the “Blitz spirit” wasn’t a lie, but it was a myth in the academic sense: a simplified, selective story built from the most comforting parts of the past.

    Wartime Britain was not uniformly united, stoic and proud. There were deep class divides. Looting occurred. Morale was rock-bottom in many cities and communities. Evacuees weren’t always welcomed with open arms. Government censorship and transnational propaganda masked social unrest.

    Understandably, these messy realities were left out of the postwar narrative. But what happens when we bring that myth into the present?

    The myth of the ‘Blitz spirit’

    Londoners did come together after the 7/7 bombings – there were undoubtedly examples of communities and strangers supporting each other and maintaining a sense of resilience that enabled them to continue their lives undeterred.

    But it was not one single unified message. Hate crimes against British Muslim communities in the weeks after the 2005 attacks exposed cracks in the narrative of national unity.

    Some used the Blitz spirit to support Tony Blair and George W. Bush, casting them as Churchillian leaders standing firm against a new fascism in the form of global terrorism. For others, the same figures represented a betrayal of British values.

    They were evoked instead to shame Blair and Bush. The Express made its feelings clear when it said: “It was throw up time when Blair was compared to Churchill by some commentators. What an insult!”

    The Blitz spirit also became a weapon in anti-immigration discourse. Some argued that Britain, unlike in 1940, had become a “soft touch” – compromised by EU human rights laws, welfare handouts and multiculturalism. The underlying message: today’s London could never be as brave or unified as wartime London.

    Writing in The Sun, Richard Littlejohn said: “War office memo. Anyone caught fighting on the beaches will be prosecuted for hate crimes.”

    An article in the Express condemning human rights laws said: “What a good thing these people weren’t running things when Hitler was doing his worst. Would the second world war have been more easily won if we had spent more time talking about freedom of speech than bombing Nazi Germany?”

    Multicultural resilience

    And yet, another narrative emerged – one that saw London’s multicultural identity as a strength, not a weakness. Here, the Blitz spirit wasn’t just a historical relic, but a kind of transcendental force. The city’s soul, it was said, remained resilient – passed down across generations, regardless of race, class or religion. For some, this was proof that Britain had evolved and still held fast to its best values.

    A letter to the Daily Mirror (July 17) invoked the Blitz spirit through a cross-cultural lens: “Colour, creed and cultures forgotten, black helping white and vice versa… We stood firm in the Blitz and we’ll do so again, going about our business as usual.”

    The Sunday Times quoted Michael Portillo, who framed London’s resilience as multicultural continuity: “Fewer than half the names of those killed on the 7th look Anglo-Saxon… Today’s Londoners come in all colours and from every cultural background. Yet they have inherited the city’s historic attitudes of nonchalance, bloody-mindedness and defiance.”

    The Blitz spirit, as my research revealed, is not a single story. It is a narrative tool used for many different – often opposing – purposes. It can bring people together, or be used to divide. It can inspire pride, or be weaponised in fear.

    National myths don’t just reflect who we were – they shape who we think we are. They’re never neutral. They’re always curated, always contested. If we want to be genuinely proud of our country – and we should – then we also have to be honest about the stories we cling to. We must ask: what’s left out, and who decides?

  • MIL-OSI Analysis: A surprisingly effective way to save the capercaillie: keep its predators well-fed – new research

    Source: The Conversation – UK – By Chris Sutherland, Reader in Statistical Ecology, University of St Andrews

    Conserving species can be a complicated affair. Take this dilemma.

    After being hunted to near extinction, numbers of a native predator are recovering and eating more of an endangered prey species, whose own numbers are declining as a result. Should conservationists accept that some successes mean losing other species, or reinstate lethal control of this predator in perpetuity?

    Or perhaps there is a third option that involves new means of managing species in the face of new conditions. This issue is playing out globally, as land managers grapple with predators such as wolves and lynx reclaiming their historic ranges.

    In the ancient Caledonian pine forests of Scotland there are fewer than 500 capercaillie remaining. This grouse is beset by multiple threats, not least shifts in spring weather caused by climate change that are driving its Europe-wide decline, relating to changes in when chicks are reared and available nutrition.

    Additionally, and in common with other ground-nesting birds, capercaillie lose eggs and chicks to carnivores. As such, the recovery of the pine marten (a relative of weasels and otters) from its own near extinction in Scotland is contributing to the decline of capercaillie.

    Jack Bamber

    Internationally, little has been achieved to slow the heating of Earth’s climate, and decades of dedicated conservation efforts have not arrested the decline of capercaillie. Extinction will follow unless new solutions are found.

    Killing pine martens, the capercaillie’s predators, might offer short-term relief, but it is socially and politically contested and scientific evidence on its effectiveness is meagre. Most importantly, it risks undermining the recovery of species conservationists have worked hard to restore. Instead, the challenge is to reduce the effects of predators, not their numbers, and encourage coexistence between species.

    We have tried one such method in Scotland – with incredibly positive results.

    A non-lethal alternative for controlling predators

    Our idea is simple: predators have to be efficient, so when given access to a free meal, they are less likely to hunt for harder-to-find prey like capercaillie nests.

    Taking the bait: a pine marten eating carrion.
    Jack Bamber

    Satiated predators are less likely to kill and eat prey that is of concern to conservationists. This is called diversionary feeding: giving predators something easy to eat at critical times, such as during the time when capercaillie build their ground nests and rear chicks between April and July.

    To test this idea we systematically dumped deer carrion across 600 square kilometres of the Cairngorms national park in north-eastern Scotland, during eight weeks in which capercaillie are laying and incubating eggs. This area is home to the last Scottish stronghold of capercaillie. We also made artificial nests across the same area that contained chicken eggs, to represent capercaillie eggs.

    Through this landscape-scale experiment, we showed that the predation rate of pine marten on artificial nests fell from 53% to 22% with diversionary feeding. This decrease from a 50% chance of a nest being eaten by a pine marten, to 20%, is a massive increase in nest survival.

    Jack Bamber

    This was a strong indication that the method worked. But we were unsure whether the effect seen in artificial nests translated to real capercaillies, and the number of chicks surviving to independence.

    Counting chicks in forests with dense vegetation is difficult, and land managers are increasingly reluctant to use trained dogs. Our innovation was to count capercaillie chicks using camera traps (motion-activated cameras which can take videos and photos) at dust baths, which are clear patches of ground where chicks and hens gather to preen.

    We deployed camera traps across the landscape in areas with and without diversionary feeding and measured whether a female capercaillie had chicks or not, and how many she had. Chicks are fragile and many die early in life. The number of chicks in a brood declined at the same rate in the fed and unfed areas.

    However, in areas where predators received diversionary feeding, 85% of the hens we detected had chicks compared to just 37% where predators were unfed. That sizeable difference mirrored the improvement seen in artificial nest survival.

    Fewer nests being predated led to more hens with broods, such that by the end of the summer, we observed a staggering 130% increase in the number of chicks per hen in fed areas – 1.9 chicks per hen were seen compared to half that in unfed areas.

    So, does diversionary feeding provide a non-lethal alternative to managing conservation conflict and promoting coexistence? Our work suggests it does.

    A mature capercaillie brood.
    Jack Bamber

    Diversionary feeding is now a key element of the capercaillie emergency plan, which is the Scottish government’s main programme for recovering the species. Diversionary feeding will probably be adopted across all estates with capercaillie breeding records in the Cairngorms national park by 2026.

    This rapid implementation of scientific evidence is a direct result of working closely, from conception, with wildlife managers and policy makers. For capercaillie, diversionary feeding has real potential to make a difference, a glimmer of hope in their plight (some nicer weather in spring might help too).

    More broadly, for conservationists, land managers, gamekeepers, farmers, researchers and anyone else involved in managing wildlife, this work is testament to the fact that, with the right evidence and a willingness to adapt, we can move beyond the binaries of killing or not killing. Instead, finding smarter ways to promote the coexistence of native predators and native prey.

    MIL OSI Analysis –

  • MIL-OSI Analysis: The NHS ten-year health plan is missing a crucial ingredient: nature

    The UK government has finally unveiled its much anticipated ten-year Plan for improving England’s health. It contains a long overdue focus on prevention, after years of sidestepping by previous administrations.

    The plan rightly recognises that preventing illness before it begins is the most effective way to improve people’s wellbeing. It should have the added benefit of reducing strain on the NHS and easing the nation’s financial burden.

    Mental health, too, is given the attention it deserves. Recognised as integral to our overall health, its inclusion couldn’t be more timely. A 2023 international study found that one in two people will experience a mental health condition in their lifetime — a much higher figure than previously estimated.

    But one striking omission threatens to undermine the plan’s success: nature. Evidence tells us that it’s one of the most powerful means of supporting physical and mental health. And yet is not mentioned once in the plan’s 168 pages.

    If this plan is about prevention, then nature should be central to it. The science is unequivocal: contact with the natural world supports human health in wide ranging and profound ways. It lowers stress, improves mood, and alleviates symptoms of anxiety.

    For children, time in nature can even aid brain development. Nature helps reduce exposure to air pollution, moderates urban heat, and fosters physical activity and social connection.

    It can also reduce feelings of loneliness, improve the diversity of our gut microbiota – by exposing us to a wider range of environmental microbes that help train and balance the immune system – and support the immune system by reducing inflammation. All of these play a vital role in protecting against chronic disease.

    People feel lonelier in crowded cities – but green spaces can help

    Then there are the intangible yet no less important benefits. Nature provides a sense of awe and wonder – feelings that help us gain perspective, boost emotional resilience and find deeper meaning in everyday life.

    Our own research shows that even small, everyday moments in nature, watching birds from your window, for example, or pausing under a blooming tree on your way to the shop, can significantly boost mental wellbeing.

    Consider this: a Danish study found that growing up near green spaces during the first ten years of life reduces the risk of developing mental health problems in adulthood by a staggering 55%. A UK study similarly showed that people living in greener neighbourhoods were 16% less likely to experience depression and 14% less likely to develop anxiety.

    And as heatwaves become more frequent and intense – with soaring illness and mortality rates – the cooling effects of trees and parks will become more vital than ever for protecting our health.

    Not all green space is equal

    But it’s not just access to green space that matters – it’s also the quality of that space.

    Green areas rich in biodiversity, with a wide variety of plant life, birds, insects and fungi, provide much greater health benefits than sparse or manicured lawns. Biodiversity builds resilience not just in ecosystems, but in our bodies and minds.

    A recent study in The Lancet Planetary Health found that people living in areas with greater bird diversity were significantly less likely to experience depression and anxiety, even after accounting for socioeconomic and demographic factors.

    This research underlines a simple but urgent truth: we cannot talk about human health without talking about biodiversity.

    Why diversity in nature could be the key to mental wellbeing

    To deliver true prevention and resilience, we need a joined-up approach across government: one that aligns health policy with environmental protection, housing, urban design, education and transport. This means rethinking how we plan and build our communities: what kind of housing we develop, how we move around, what we grow and eat and how we live in relationship with the ecosystems that support us.

    There are many ways this vision can be put into action. The Neighbourhood Health Service outlined in the ten-year plan could be tied directly to local, community-led efforts such as Southwark’s Right to Grow campaign, which gives residents the right to cultivate unused land. This kind of initiative improves access to fresh food, promotes physical activity, strengthens community bonds and increases green cover – all of which support long-term health.

    School curricula could be revised to give children the opportunity to learn not just about nature, but also in nature – developing ecological literacy, emotional resilience and healthier habits for life. Health professionals could be trained to understand and promote the value of time outdoors for managing chronic conditions and supporting recovery. Green social prescribing – already gaining ground across the UK – should be fully integrated into standard care, with robust resourcing and cross-sector support.

    Learning from success

    Scotland’s Green Health Partnerships show what’s possible. These initiatives bring together sectors including health, environment, education, sport and transport to promote nature-based health solutions – from outdoor learning and physical activity in parks, to conservation volunteering and nature therapy.

    They don’t just improve health; they strengthen communities, build climate resilience and create cost-effective, scaleable solutions for prevention.

    The ten-year plan is a once-in-a-generation opportunity. It could help remove departmental silos and unify national goals across health, climate, inequality and economic recovery, while saving billions in the process. But in its current form, it misses a crucial ingredient.

    By failing to recognise the centrality of nature in our health, the government overlooks one of the simplest and most effective ways to build resilience – both human and ecological. Surely it is not beyond a nation of nature lovers to put nature at the heart of our future health?

  • MIL-OSI Analysis: The ‘Mind’ diet is good for cognitive health – here’s what foods you should put on your plate

    Source: The Conversation – UK – By Aisling Pigott, Lecturer, Dietetics, Cardiff Metropolitan University

    There’s long been evidence that what we eat can affect our risk of dementia, Alzheimer’s disease and cognitive decline as we age. But can any one diet actually keep the brain strong and lower dementia risk? Evidence suggests the so-called “Mind diet” might.

    The Mind diet (which stands for the Mediterranean-Dash intervention for neurocognitive delay) combines the well-established Mediterranean diet with the “Dash” diet (dietary approaches to stop hypertension). However, it also includes some specific dietary modifications based on their benefits to cognitive health.

    Both the Mediterranean diet and Dash diet are based on traditional eating patterns from countries which border the Mediterranean sea.

    Both emphasise eating plenty of plant-based foods (such as fruits, vegetables, nuts and seeds), low-fat dairy products (such as milk and yoghurts) and lean proteins including fish and chicken. Both diets include very little red and processed meats. The Dash diet, however, places greater emphasis on consuming low-sodium foods, less added sugar and fewer saturated and trans-fats to reduce blood pressure.

    Both diets are well-researched and shown to be effective in preventing lifestyle-related diseases – including cardiovascular disease and hypertension. They’re also shown to help protect the brain’s neurons from damage and benefit cognitive health.

    The Mind diet follows many of the core tenets of both diets but places greater emphasis on consuming more foods that contain nutrients which promote brain health and prevent cognitive decline, including:

    Numerous studies have been conducted on the Mind diet, and the evidence for this dietary approach’s brain health benefit is pretty convincing.

    For instance, one study asked 906 older adults about their usual diet — giving them a “Mind score” based on the number of foods and nutrients they regularly consumed that are linked with lower dementia risk. The researchers found a link between people who had a higher Mind diet score and slower cognitive decline when followed up almost five years later.

    Another study of 581 participants found that people who had closely followed either the Mind diet or the Mediterranean diet for at least a decade had fewer signs of amyloid plaques in their brain when examined post-mortem. Amyloid plaques are a key hallmark of Alzheimer’s disease. Higher intake of leafy greens appeared to the most important dietary component.

    A systematic review of 13 studies on the Mind diet has also found a positive association between adherence to the Mind diet and cognitive performance and function in older people. One paper included in the review even demonstrated a 53% reduction in Alzheimer’s disease risk in those that adhered to the diet.

    The Mind diet encourages eating berries, which contain a plant compound thought to be beneficial for the brain.

    It’s important to note that most of this research is based on observational studies and food frequency questionnaires, which have their limitations in research due to reliabiltiy and participant bias. Only one randomised control trial was included in the review. It found that women who were randomly assigned to follow the Mind diet over a control diet for a short period of time showed a slight improvement in memory and attention.

    Research in this field is ongoing, so hopefully we’ll soon have a better understanding of the diet’s benefits – and know exactly why it’s so beneficial.

    Mind your diet

    UK public health guidance recommends people follow a balanced diet to maintain good overall health. But the Mind diet offers a more targeted approach for those hoping to look after their cognitive health.

    While public health guidance encourages people to eat at least five portions of fruit and vegetables daily, the Mind diet would recommend choosing leafy green vegetables (such as spinach and kale) and berries for their cognitive benefits.

    Similarly, while UK guidance says to choose unsaturated fats over saturated ones, the Mind diet explicitly recommends that these fats come from olive oil. This is due to the potential neuroprotective effects of the fats found in olive oil.

    If you want to protect your cognitive function as you age, here are some other small, simple swaps you can make each day to more closely follow the Mind diet:

    • upgrade your meals by sprinkling nuts and seeds on cereals, salads or yoghurts to increase fibre and healthy fats
    • eat the rainbow of fruit and vegetables, aiming to fill half your plate with these foods
    • canned and frozen foods are just as nutrient-rich as fresh fruits and vegetables
    • bake or airfry vegetables and meats instead of frying to reduce fat intake
    • opt for poly-unsaturated fats and oils in salads and dressings – such as olive oil
    • bulk out meat or meat alternatives with pulses, legumes chickpeas or beans. These can easily be added into dishes such as spaghetti bolognese, chilli, shepherd’s pie or curry
    • use tinned salmon, mackerel or sardines in salads or as protein sources for meal planning.

    These small changes can have a meaningful impact on your overall health – including your brain’s health. With growing evidence linking diet to cognitive function, even little changes to your eating habits may help protect your mind as you age.

  • MIL-OSI Analysis: Ageing isn’t the same everywhere – why inflammation may be a lifestyle problem

    For years, scientists have believed that inflammation inevitably increases with age, quietly fuelling diseases like heart disease, dementia and diabetes. But a new study of Indigenous populations challenges that idea and could reshape how we think about ageing itself.

    For decades, scientists have identified chronic low-level inflammation – called “inflammaging” – as one of the primary drivers of age-related diseases. Think of it as your body’s immune system stuck in overdrive – constantly fighting battles that don’t exist, gradually wearing down organs and systems.

    But inflammaging might not be a universal feature of ageing after all. Instead, it could be a byproduct of how we live in modern society.

    Get your news from actual experts, straight to your inbox. Sign up to our daily newsletter to receive all The Conversation UK’s latest coverage of news and research, from politics and business to the arts and sciences.

    The research, published in Nature Aging, compared patterns of inflammation in four very different communities around the world. Two groups were from modern, industrialised societies – older adults living in Italy and Singapore.

    The other two were Indigenous communities who live more traditional lifestyles: the Tsimane people of the Bolivian Amazon and the Orang Asli in the forests of Malaysia.

    The researchers analysed blood samples from more than 2,800 people, looking at a wide range of inflammatory molecules, known as cytokines. Their goal was to find out whether a pattern seen in earlier studies – where certain signs of inflammation rise with age and are linked to disease – also appears in other parts of the world.

    The answer, it turns out, is both yes and no.

    Among the Italian and Singaporean participants, the researchers found a fairly consistent inflammaging pattern. As people aged, levels of inflammatory markers in the blood, such as C-reactive protein and tumour necrosis factor, rose together. Higher levels were linked to a greater risk of chronic diseases including kidney disease and heart disease.

    But in the Tsimane and Orang Asli populations, the inflammaging pattern was absent. The same inflammatory molecules did not rise consistently with age, and they were not strongly linked to age-related diseases.

    In fact, among the Tsimane, who face high rates of infections from parasites and other pathogens, inflammation levels were often elevated. Yet this did not lead to the same rates of chronic diseases that are common in industrialised nations.

    Despite high inflammatory markers, the Tsimane experience very low rates of conditions such as heart disease, diabetes and dementia.

    Inflammaging may not be universal

    These results raise important questions. One possibility is that inflammaging, at least as measured through these blood signals, is not a universal biological feature of ageing. Instead, it may arise in societies marked by high-calorie diets, low physical activity and reduced exposure to infections.

    In other words, chronic inflammation linked to ageing and disease might not simply result from an inevitable biological process, but rather from a mismatch between our ancient physiology and the modern environment.

    The study suggests that in communities with more traditional lifestyles – where people are more active, eat differently and are exposed to more infections – the immune system may work in a different way. In these groups, higher levels of inflammation might be a normal, healthy response to their environment, rather than a sign that the body is breaking down with age.

    Another possibility is that inflammaging may still occur in all humans, but it might appear in different ways that are not captured by measuring inflammatory molecules in the blood. It could be happening at a cellular or tissue level, where it remains invisible to the blood tests used in this research.

    Chronic low-level inflammation may be a lifestyle problem.

    Why this matters

    If these findings are confirmed, they could have significant consequences.

    First, they challenge how we diagnose and treat chronic inflammation in ageing. Biomarkers used to define inflammaging in European or Asian populations might not apply in other settings, or even among all groups within industrialised nations.

    Second, they suggest that lifestyle interventions aimed at lowering chronic inflammation, such as exercise, changes in diet, or drugs targeting specific inflammatory molecules, might have different effects in different populations. What works for people living in cities might be unnecessary, or even ineffective, in those living traditional lifestyles.

    Finally, this research serves as an important reminder that much of our knowledge about human health and ageing comes from studies conducted in wealthy, industrialised nations. Findings from these groups cannot automatically be assumed to apply worldwide.

    The researchers are clear: this study is just the beginning. They urge scientists to dig deeper, using new tools that can detect inflammation not just in the blood, but within tissues and cells where the real story of ageing may be unfolding. Just as important, they call for more inclusive research that spans the full range of human experience, not just the wealthy, urbanised corners of the world.

    At the very least, this study offers an important lesson. What we thought was a universal truth about the biology of ageing might instead be a local story, shaped by our environment, lifestyle and the way we live.

  • MIL-OSI Analysis: NHS ten-year plan for England: what’s in it and what’s needed to make it work

    Source: The Conversation – UK – By Judith Smith, Professor of Health Policy and Management, University of Birmingham

    The UK government has published its eagerly awaited ten-year health plan for England, setting out how billions of pounds in NHS funding will be used to transform healthcare delivery across the country.

    As anticipated, the plan is framed around the government’s three missions for the NHS: shifting care from hospital into the community, moving from analogue to digital communication, and focusing on preventing ill health rather than treating illness.

    The 168-page document responds to a stark warning that the NHS is “in serious trouble”. It is remarkable for the sheer number of ideas and proposals. As well as describing major new developments to improve people’s access to local in-person and virtual NHS care and disease prevention, it sets out a blizzard of other proposals.

    These include abolishing Healthwatch (a national watchdog that listens to people’s views on health and social care services to improve them), and bringing back some of the reforms of the Tony Blair era such as “new foundation trusts” and using private funding for new buildings.

    From hospital to community

    The big idea in the ten-year plan is a neighbourhood health service: large local health centres where people can access GP, nursing, dental, pharmacy, diagnostic and other services six days a week, 12 hours a day. These are intended to relieve pressure on hospitals and emergency departments, eventually replacing many outpatient clinics.

    The idea of shifting care into the community is not new. It has been advocated for over 30 years, including in the NHS white paper of 1997, the 2006 policy paper Our health, our care, our say, the NHS five-year forward view of 2014, and the NHS long-term plan of 2019.

    Some progress has been made in this direction. For example, much of the care for people living with asthma and diabetes is now provided in local general practices. Many general practices already have large teams of doctors, nurses, pharmacists, physiotherapists and other staff who offer aspects of the wider “neighbourhood care” described in the new plan.

    But what has not been achieved is having larger-scale primary care teams consistently available across the NHS. The new plan proposes new contracts and shifts of funding to enable wider change, and while welcome, these will be challenging to put into practice against a backdrop of major service pressures.

    From analogue to digital

    The plan emphasises strongly the need to extend the role of the NHS app, with it becoming the “doctor in your pocket” and the main route into NHS services. It proposes that the app holds your full patient record, enables you to book GP and hospital appointments and becomes a key source of healthcare advice.

    This sounds very attractive. However, the devil will be in the detail. There are so many NHS IT systems to harmonise, and major data security and privacy issues to overcome.

    Most critically, much attention must be given to sorting out basic NHS admin systems that are too often confusing and paper-based. This will entail lots of work with NHS clinical and administrative staff, changing long-standing ways of working, introducing new technology and adapting “the way we do things round here”.

    Using AI to record doctor visits, understand test results and give health advice could really change how healthcare works. But this will take lots of time and money to train staff, try out new systems and put them in place. Also, people will need clear information about what to expect from their local health services in the future.

    From sickness to prevention

    England is getting sicker, and there are stark inequalities between the richest and the poorest.

    To achieve the plan’s goal of empowering people to make healthier choices, robust cross-government action is essential across sectors, including housing, education and welfare. While some important measures such as the tobacco and vapes bill, plans to measure supermarkets’ sales of healthy foods, and the expansion of free school meals are included in the plan, others such as minimum alcohol pricing have been notably excluded.

    Integrated care boards (ICBs), the regional bodies who plan and fund NHS services in England, and local councils will be vital in enabling these public health measures to be implemented. However, this will be difficult in the short to medium term as ICBs are being forced to merge, cut headcount and reorganise their work.

    Making it work

    For the ten-year plan to succeed, three key elements are essential.

    First, there is an urgent need to set priorities. The public expects much swifter access to on-the-day GP appointments, an end to excessive waits in accident and emergency departments, and reductions in waiting lists for operations.

    The Department of Health and Social Care must guide the NHS in which aspects of the plan are to be addressed first. If everything is a priority, nothing is a priority.

    Second, implementation really matters. There is only so much management capacity, staff time, funding and goodwill to introduce new technologies and services. This government has already embarked on another “redisorganisation” of the oversight agency NHS England, and now plans to axe or merge a number of other national and local NHS bodies. NHS managers are vital to implementing the plan, but need to feel valued and supported, not denigrated as superfluous.

    Finally, the plan is almost silent on the two most pressing needs for government health reform. Without a properly funded system of adult social care to support older people and those living with enduring mental health needs, it is hard to see how hospital care can be transformed.

    And without an urgent and significant shift of resources to general practice and community services, neighbourhood health services will remain more of a dream than reality.

    The UK government has published its eagerly awaited ten-year health plan for England, setting out how billions of pounds in NHS funding will be used to transform healthcare delivery across the country.

    As anticipated, the plan is framed around the government’s three missions for the NHS: shifting care from hospital into the community, moving from analogue to digital communication, and focusing on preventing ill health rather than treating illness.

    The 168-page document responds to a stark warning that the NHS is “in serious trouble”. It is remarkable for the sheer number of ideas and proposals. As well as describing major new developments to improve people’s access to local in-person and virtual NHS care and disease prevention, it sets out a blizzard of other proposals.

    These include abolishing Healthwatch (a national watchdog that listens to people’s views on health and social care services to improve them), and bringing back some of the reforms of the Tony Blair era such as “new foundation trusts” and using private funding for new buildings.

  • MIL-OSI Analysis: In search of Labour’s ‘working people’ – the paradox at the heart of Keir Starmer’s first year in power

    It’s one year since Keir Starmer led the Labour party to a landslide victory. Starmer’s manifesto, “Change” had proposed “securonomics” as a solution to the UK’s many crises. This was sold as a way of ensuring “sustained economic growth as the only route to improving the prosperity of our country and the living standards of working people”.

    The document mentioned “working people” a total of 21 times. It was clear this demographic had been identified as the key target beneficiary of “securonomics”, otherwise referred to as “the plan for change”.

    But there is a paradox at the heart of the proposal to deliver “change” to “working people” – one that helps explain the chaos of Labour’s first year in government. By obsessively pitting this demographic against “non-working people”, Labour is in fact not promising any real change at all.

    One of the key premises of Labour’s securonomics is that growth must precede any significant investment. “Working people’s” priorities are therefore presented as being in line with that of a fiscally responsible state.

    In the autumn budget, there was a pledge to “fix the foundations of the economy and deliver change by protecting working people”. To do this, the chancellor needed to fix a “black hole” of £22 billion in government finances.

    The refusal to lift the two-child benefit cap, alongside “reforming the state to ensure […] welfare spending is targeted towards those that need it the most”, was framed as “putting more money in working people’s pockets”. There has, meanwhile, been a continued emphasis on encouraging those on benefits back to work.

    Besides the clear deepening of inequality wrought by similar reforms in the past, welfare cuts make no sense on an economic or societal level. They undermine the economy, and the consequences put additional pressure on already underfunded social services.

    As highlighted by the Office of Budgetary Responsibility (OBR), such cuts fail to deliver the promised behavioural change to force people into work. People instead become more focused on day-to-day survival.

    Despite the government’s last ditch climbdown to save its flagship welfare reform policy its cuts are still forecast to push more than 150,000 people into poverty

    Such reforms carried out in the name of “working people” perpetuate a pernicious myth of us v them. Not only are people in work also affected by these cuts but people’s lives – including their jobs, income, family situations, and health – shift regularly, making the “strivers v skivers” divide both simplistic and inaccurate.

    Even “secure borders” and “smashing the criminal gangs” were positioned as “grown up politics back in the service of working people”. This association of working people with anti-immigrant attitudes links to a broader homogenisation of “working people” as both “patriotic” and in search of “security”. “Fixing the foundations” has been depicted in several social media posts as a patriotic act via use of the Union Jack.

    Meanwhile, stage-managed photoshoots of Starmer in factories with people wearing hard hats and hi-visibility jackets give a clear impression of the types of manufacturing jobs the government believes “working people” carry out. This gives an impressions that belies the reality of modern Britain – and an economy that is dominated by the service sector,, not manufacturing or building.

    Old wine in new bottles

    While Starmer framed his “plan for change” as a break with previous administrations, his “working people” narrative betrays this claim as anything but.

    The idea that the deserving “working people” are different and separate from people who don’t (or can’t) work has been deployed by government after government to justify austerity and cuts to services. It has always been useful to separate the “scroungers from the strivers” and there is no sign of Labour changing course.

    Hello! Are you working people?
    Number 10/Flickr, CC BY-NC-ND

    The term “working people” also builds on a previous trope of the “hard-working family”.

    While initially coined by New Labour, this term has roots in Margaret Thatcher’s idea of the family, rather than the state, as the locus of welfare. It was not for the state to take care of you but your own kin.

    Like “working people” now, “hard-working families” were those who played by the rules and knuckled down to earn a living. Previous Conservative administrations have depicted “hard-working families” as burdened by the unemployed, the poor, the sick and disabled and immigrants.

    Add to this, the signalling continues to imply that the “authentic” working class of Britain are solely white – sometimes also male – and typically older, manual labourers, who are assumed to hold socially conservative views. This is another divide-and-rule trope which neglects the reality of the multiracial and multiethnic composition of the working classes.

    In light of all this, any real “change” promised in Labour’s manifesto has been betrayed by a continuity with tired and damaging tropes of deserving and undeserving people. This is contributing to the sense, a year in, that this Labour government is merely repeating past government failures rather than striking out in a new direction.

  • MIL-OSI Analysis: Will the Oasis reunion usher in a Britpop summer – or is it just a marketing ploy?

    The trend for naming summers has become something of a cultural phenomenon. Think for example of 2019, which was branded a “hot girl summer”, inspired by rapper Megan Thee Stallion’s song.

    In 2021 there was the much-ridiculed “white boy summer” (named after a song of the same name by Tom Hanks’s son, Chet). Then 2022 was “feral girl summer” and 2024, of course, was a “brat summer”, after Charli XCX’s cultural phenomenon album Brat.

    And this summer? Well, with the likes of Oasis, Pulp, Supergrass, Suede, Shed Seven and Cast all playing UK dates between June and August, it’s “Britpop summer”, of course. The question is, though, whether these names are actually (and accurately) representing the zeitgeist, or if they are just the result of savvy marketing strategies.

    Brat by Charli XCX is a work of contemporary imagist poetry – and a reclamation of ‘bratty’ women’s art

    Such things may now be occurring more frequently, but they’re nothing new. The year 1967 was famously coined “the summer of love”, a moniker supposedly invented by the Californian local government to put a positive spin on the druggy, hairy, hippy gatherings taking place across the state.

    Then, just over two decades later, there came the imaginatively titled “second summer of love” in 1988 which, like its predecessor was drug-inspired, but this time involved British ravers taking ecstasy in London warehouses instead of hippies “dropping acid” in San Franciscan parks.

    The “summer of love” has largely been presented to us as a psychedelic utopia, wherein London was the “swinging, cool and hip” epicentre of a new cultural movement. Everyone was blissfully stoned, with messages of peace and love on their lips, kaftans and floral blouses on their bodies and flowers in their hair.

    In reality, though, in the UK at least only 8% of adults had actually tried cannabis and fewer than 1% had taken LSD or acid, and the fashion of the day (for men, anyway) involved sensible slacks and short-back-and-sides.

    Such un-psychedelic appetites also spilled over into mainstream music. Although it’s now the UK’s bestselling album ever, in 1967, The Beatles’ Sgt. Pepper’s Lonely Hearts Club Band was only the sixth-biggest album of the year in terms of sales. It was bested by the very suitably non-flower-power Herb Alpert, The Monkees and The Sound of Music soundtrack.

    Pink Floyd’s debut album, The Piper at the Gates of Dawn – “the founding masterpiece in psychedelic music” – sold 275,000 copies in 1967 in the UK (compared to The Sound of Music’s 2.4 million) and was number 34 on the list of big-selling albums in the UK that year.

    The same year, 1967, also saw the “best double-A side ever released”, The Beatles’ Penny Lane and Strawberry Fields Forever. It was kept off the number one spot by Engelbert Humperdinck’s Please Release Me.

    Inside the so-called ‘second summer of love’.

    It seems, then, that for most of the British public, it was less a “summer of love” and more a “summer of Humperdinck”. Fast-forward five decades, and we see the same kinds of things happening. The year 2019 was a “hot girl summer”, Megan Thee Stallion’s song only peaked at 40 in the UK singles charts and her gigs sold poorly.

    Like our “summer of Humperdinck”, were such things based on popularity, we may have expected a “Sheeran summer”, with Ed Sheeran’s duet with Justin Bieber, I Don’t Care, dominating the charts and airwaves.

    Similarly, although 2024 was a “brat summer”, Charli XCX’s album was actually only the UK’s eighth-biggest selling album of the year, with Taylor Swift’s very un-Brat-like The Tortured Poets Department achieving 783,820 sales – almost double Brat’s.

    Britpop summer

    Britpop itself may have peaked in 1995, but in the summer of 1996, with Oasis and Blur still omnipresent, Tony Blair talking about the prospect of freedom, aspiration and ambition, England progressing through the Euros on home soil, and sunny day after sunny day, it was (according to The Guardian, at least) the most optimistic period in recent British history where anything seemed possible.

    Pulp performed a secret set at Glastonbury 2025 to huge crowds.

    We may all have become more cynical in the intervening years, but in the midst of another heatwave, with Pulp at Glastonbury, and the Gallaghers reunited, it does feel like there’s something in the air again.

    Indeed, standing among tens of thousands of fellow music fans in the sweltering heat watching Jarvis Cocker strutting his gangly stuff, if I ignored the grey in his beard, the iPhones in the crowd, and the aching in my legs, it could have been the nineties all over again.

    Britpop summer? I’m all for it. And maybe this will be one time that the name really does represent the nation’s mood.

  • MIL-OSI Analysis: The existentialist philosophy of Lana Del Rey

    Source: The Conversation – UK – By King-Ho Leung, Lecturer in Theology, Philosophy and the Arts, King’s College London

    Speaking to Myspace as an upcoming artist in 2013, Lana Dey Rey said that the “vision of making [her] life a work of art” was what inspired her to create her music video for her breakthrough single, Video Games (2011).

    The self-made video, featuring old movies clips and webcam footage of Del Rey singing, went viral. It eventually led her to sign with a major record label. For many, the video conveyed a sense of authenticity. However, upon discovering that “Lana Del Rey” was a pseudonym (her real name is Elizabeth Grant), some fans began to have doubts. Perhaps this self-made video was just another calculated marketing scheme?

    The question of Del Rey’s authenticity has puzzled many throughout her career. Consider, for instance, the controversial Judah Smith Interlude from her latest album, Did You Know That There’s a Tunnel Under Ocean Blvd? (2023). Both fans and critics – including her sizeable LGBTQ+ fanbase – were surprised and troubled by her decision to feature the megachurch pastor Judith Smith, who’s been accused of homophobia.

    However, the meaning of Del Rey’s inclusion of Smith’s sermon soundclips, layered under a recording of Del Rey giggling, is unclear. Is this meant to mock Smith, or even Christianity itself? Or is it an authentic expression of Del Rey’s own spirituality? After all, she repeatedly makes references to her “pastor” in the same album’s opening track The Grants, about her family in real life.

    Before she became a singer-songwriter, Del Rey gained her philosophy degree at Fordham University. It was the mid-2000s, when the eminent existentialism scholar Merold Westphal would have been on staff, so she probably studied theories of authenticity by existentialists such as Jean-Paul Sartre (1905–80) and Martin Heidegger (1889–1976). Heidegger spoke of human existence as a “being-towards-death”. Or as Del Rey sings in the title track of her first major-label album, “you and I, we were born to die”.

    In Heidegger’s view, to pretend that we are not all bound to die is to deny the kind of finite beings which we are: it is to disown ourselves and exist inauthentically. Conversely, to exist authentically is to accept our own mortality and embrace the way we exist as finite beings.

    The music video for Video Games.

    In this understanding, to exist authentically does not mean the expression of some underlying “true self” or “human nature”. Rather, it is to accept the conditions of life in which we find ourselves.

    ‘An obsession for freedom’

    For existentialist philosophers, such conditions include not only mortality but also freedom – a theme particularly emphasised by Sartre.

    As Sartre says in his 1946 lecture Existentialism Is a Humanism, existentialism holds that “there is no human nature, because there is no God to have a conception of it … Man is nothing else but that which he makes of himself”.

    With no creator God or pre-established human nature to determine human destiny or purpose, Sartre teaches that human beings are “condemned to freedom”. We are free beings who are always acting freely – whether we acknowledge that we are free or not. To pretend that we are not free is to be inauthentic.

    Sartre suggests embracing our freedom means living life in a manner “comparable to the construction of a work of art”. In his view, in both art and life, we cannot decide in advance what actions ought to be taken: “No one can tell what the painting of tomorrow will be like; one cannot judge a painting until it is done.”

    Likewise, we cannot judge whether or not a life is well-lived until it is finished. We must not predetermine how someone should live according to some pre-established criterion of “human nature”.

    Instead, we can only assess someone’s life by considering whether they accept that they are free, with the freedom and responsibility to create meaning for their existence by living life as a work of art.

    Both freedom and making life a work of art are recurring themes in Del Rey’s discography. They are brought together perhaps most memorably in her much-loved monologue in the music video for Ride (2012):

    On the open road, we had nothing to lose, nothing to gain, nothing we desired anymore, to make our lives into a work of art: Live fast, die young, be wild, and have fun. I believe in the country America used to be. I believe in the person I want to become. I believe in the freedom of the open road.

    Del Rey is someone Elizabeth Grant became. As though echoing Sartre’s comparison between making art and living life, in her 2012 song Gods & Monsters, she sings of herself “posing like a real singer – cause life imitates art”.

    For Del Rey, being a public-facing “real singer” involves some kind of image-cultivation or even self-cultivation. Not unlike how her music video for Video Games is “self-made”, the very identity of Lana Del Rey is also “self-made”. The image of Lana is a work of art made by the artist, Del Rey herself.

    To be an “authentic” or “real” singer is to accept that the persona of a public figure is always inevitably curated. To combine Sartre’s slogan and Del Rey’s lyrics, the real singer is always “condemned to posing”. To pretend otherwise is to disown what it is to be a “real singer” and to act inauthentically.

    If it is true that, as Del Rey sings, “life imitates art”, to render life as a work of art is the most authentic thing that a person can do. Because to live life as a work of art is nothing other than authentically accepting life as it is, something that itself “imitates art”. As she sings in Get Free (2017), this is Del Rey’s commitment, her modern manifesto.

  • MIL-OSI Analysis: Salmonella cases are at ten-year high in England – here’s what you can do to keep yourself safe

    Source: The Conversation – UK – By Rob Kingsley, Professor, Microbiology, Quadram Institute

    Salmonella cases in England are the highest they’ve been in a decade, according to recent UK Health Security Agency (UKHSA) data. There was a 17% increase in cases observed from 2023 to 2024 – culminating in 10,388 detected infections last year. Children and older adults accounted for around a fifth of cases.

    Although the number of infections caused by foodborne diseases such as Salmonella had broadly decreased over the last 25 years, this recent spike suggests a broader issue is at play. A concurrent increase in Campylobacter cases points to a possible common cause that would affect risk of both foodborne pathogens – such as changes in consumer behaviour or food supply chains.

    While the UK maintains a high standard of food safety, any increase in the incidence of pathogens such as Salmonella warrants serious attention.

    Salmonella is a species of bacteria that is one of the most common causes of foodborne illnesses globally. The bacteria causes salmonellosis – an infection that typically causes vomiting and diarrhoea.

    Most cases of salmonellosis don’t require medical intervention. But approximately one in 50 cases results in more serious blood infections. Fortunately, fatalities from Salmonella infections in the UK are extremely rare – occurring in approximately 0.2% of all reported infections.

    Salmonella infections are typically contracted from contaminated foods. But a key challenge in controlling Salmonella in the food supply chain lies in the diverse range of foods it can contaminate.

    Salmonella is zoonotic, meaning it’s present in animals, including livestock. This allows it to enter the food chain and subsequently cause human disease. This occurs despite substantial efforts within the livestock industry to prevent it from happening – including through regular testing and high welfare practices.

    Salmonella can be present on many retail food products – including raw meat, eggs, unpasteurised milk, vegetables and dried foods (such as nuts and spices). When present, it’s typically at very low contamination levels. This means it doesn’t pose a threat to you if the product is stored and cooked properly.

    Vegetables and leafy greens can also become contaminated with Salmonella through cross-contamination, which may occur from contaminated irrigation water on farms, during processing or during storage at home. As vegetables are often consumed raw, preventing cross-contamination is particularly critical.

    Spike in cases

    It’s premature to draw definitive conclusions regarding the causes of this recent increase in Salmonella cases. But the recent UKHSA report suggests the increase is probably due to many factors.

    One contributing factor is that diagnostic testing has increased. This means we’re better at detecting cases. This can be viewed as a positive, as robust surveillance is integral to maintaining a safe food supply.

    The UKHSA also suggests that changes in the food supply chain and the way people are cooking and storing their food due to the cost of living crisis could also be influential factors.

    To better understand why Salmonella cases have spiked, it will be important for researchers to conduct more detailed examinations of the specific Salmonella strains responsible for the infections. While Salmonella is commonly perceived as a singular bacterial pathogen, there are actually numerous strains (serotypes).

    DNA sequencing can tell us which of the hundreds of Salmonella serotypes are responsible for human infections. Two serotypes, Salmonella enteritidis and Salmonella Typhimurium, account for most infections in England.

    Although the UKHSA reported an increase in both serotypes in 2024, the data suggests that Salmonella enteritidis has played a more significant role in the observed increase. This particular serotype is predominantly associated with egg contamination.

    Salmonella enteritidis is now relatively rare in UK poultry flocks thanks to vaccination and surveillance programmes that were introduced in the 1980s and 1990s. So the important question here is where these additional S enteritidis infections are originating.

    Although the numbers may seem alarming, what the UKHSA has reported is actually a relatively moderate increase in Salmonella cases. There’s no reason for UK consumers to be alarmed. Still, this data underscores the importance of thoroughly investigating the underlying causes to prevent this short-term increase from evolving into a longer-term trend.

    Staying safe

    The most effective way of lowering your risk of Salmonella involves adherence to the “4 Cs” of food hygiene:

    1. Cleaning

    Thoroughly wash hands before and after handling any foods – especially raw meat. It’s also essential to keep workspaces, knives and utensils clean before, during and after preparing your meal.

    2. Cooking

    The bacteria that causes Salmonella infections can be inactivated when cooked at the right temperature. In general, foods should be cooked to an internal temperature above 65°C – which should be maintained for at least ten minutes. When re-heating food, it should reach 70°C or above for two minutes to kill any bacteria that have grown since it was first cooked.

    3. Chilling

    Raw foods – especially meat and dairy – should always be stored below 5°C as this inhibits Salmonella growth. Leftovers should be cooled quickly and also stored at 5°C or lower.

    4. Cross-contamination

    To prevent Salmonella passing from raw foods to those that are already prepared or can be eaten raw (such as vegetables and fruit), it’s important to wash hands and clean surfaces after handling raw meat, and to use different chopping boards for ready-to-eat foods and raw meat.

    Most Salmonella infections are mild and will go away in a few days on their own. But taking the right steps when storing and preparing your meals can significantly lower your risk of contracting it.
