by Angharad Brewer Gillham, Frontiers science writer Image/Seth Phillips Termites are a crucial source of nutrients for chimpanzees, who fish for them with tools, but they’re not always accessible. Now, researchers copying chimpanzee tools and techniques have shown that chimpanzees living in western Tanzania can only reliably fish for termites in the early wet season, when other foods are abundant. These chimpanzees fish for termites because they can, not because they need to. The results raise the possibility that chimpanzees could even be predicting termite availability before they go fishing. The discovery that chimpanzees use tools to fish for termites revolutionized our understanding of their abilities — but we still don’t have crucial context to help us understand termite fishing and chimpanzee minds. Are chimpanzees fishing for a seasonal treat or trying their luck? Researchers based at the University of California Santa Cruz (UCSC) and University College London (UCL) investigated the relationship between termite availability and chimpanzee fishing. They found that termites are most available early in the wet season. Although other foods are abundant at that time, chimpanzees choose to termite fish then. “I believe these results set up an interesting hypothesis about wild chimpanzee foraging cognition,” said […]

by Deborah Pirchner, Frontiers science writer Image: Shutterstock.com Women working in agricultural sectors in low- and middle-income countries are disproportionally at risk from climate change induced hazards, such as droughts, floods, or shortened crop-growing seasons. Now, researchers have developed a map showing localities where climate change risk for women in agri-food systems is especially high. Ranking 87 countries, they found that women in central, east, and southern Africa, as well as west and south Asia are at particular risk. Threats posed by the climate crisis disproportionally affect certain communities and social groups that are more exposed. People living in low- and middle-income (LMIC) countries are at heightened risk. Within these countries, women typically face higher climate risk than men. To show where women working in agri-food systems – systems that encompass production, but also post-harvest handling and distribution – are most threated by climate change, an international team of researchers has developed a hotspot map that identifies and ranks localities by threat level. “We show that significant climate hazards, high exposure faced by women in agri-food systems, and high vulnerability faced by women due to systemic gender inequalities converge particularly in central, east, and southern Africa, as well as in […]

by Liad Hollender, Frontiers science writer Image: Shutterstock.com The UN Climate Panel’s latest best estimate is that global warming will end once we reach net zero CO2 emissions – but a study in Frontiers in Science warns significant warming could still occur. Researchers including those from Imperial College London and University of Exeter assess factors controlling global temperatures post ‘net zero’ and offer a pioneering framework for better estimating climate change risks. These risks must inform climate mitigation and adaptation policies to protect future generations. From scorching heatwaves to torrential downpours and devastating storms, the disastrous effects of global warming are sweeping across the world. Being the predicted outcome of burning fossil fuels, our best and only plan to limit warming is to reduce CO2 emissions from human activities to ‘net zero’ – where the amount of CO2 we emit into the atmosphere is equal to the amount we remove from it. To keep within the 1.5°C limit of the 2015 Paris Agreement, this needs to happen as soon as possible. Though the scientific community’s current best estimate from models is that global warming will stop at net zero, an article published in Frontiers in Science raises a red flag. […]

By Mischa Dijkstra, Frontiers science writer Researchers from Australia studied the influence of pollution on the sex ratio of clutches of sea green turtles. This species is at risk of extinction from a current lack of male hatchlings. They concluded that exposure to the heavy metals cadmium and antimony, accumulated by the mother and transferred to her eggs, may cause embryos to be feminized. Pollution may thus compound the female-biasing influence of rising global temperatures on green sea turtles. Green sea turtles, Chelonia mydas, are listed as endangered on the IUCN Red List of Threatened Species. They are at risk of extinction due to poaching, collisions with boats, habitat destruction, and accidental capture in fishing gear. But another threat, linked to climate change, is more insidious: sea turtles have temperature-dependent sex determination, which means that more and more embryos develop into females as temperatures keep rising. Already, in the northern part of the Great Barrier Reef off Australia, hundreds of females are born for every male. Now, researchers have shown that the resulting risk of extinction due to a lack of male green sea turtles may be compounded by pollution. Dr Arthur Barraza, a researcher at the Australian Rivers Institute […]

by Deborah Pirchner, Frontiers science writer Image: Shutterstock.com Forests are excellent at absorbing and storing carbon and can play a role in meeting global net zero targets. As more countries commit to forest creation, but mainly plant single species forests, an international team of researchers has examined how carbon stocks in mixed forests and monocultures compare. They found that mixed forests store more carbon, and that out of the forests assessed those with four species had the highest carbon stocks relative to monocultures. To slow the effects of climate change, conserve biodiversity, and meet the sustainable development goals, replanting trees is vital. Restored forests store carbon within the forest’s soil, shrubs, and trees. Mixed forests are especially effective at carbon storage, as different species with complementary traits can increase overall carbon storage. Compared to single-species forests, mixed forests are also more resilient to pests, diseases, and climatic disturbances, which increases their long-term carbon storage potential. The delivery of other ecosystem services is also greater in mixed species forests, and they support higher levels of biodiversity. Although the benefits of diverse forest systems are well known, many countries’ restoration commitments are focused on establishing monoculture plantations. Given this practice, an international […]

by Angharad Brewer Gillham, Frontiers science writer Image/Shutterstock.com Scientists have found that specially processed samples of willow bark extract have an antiviral effect which isn’t seen in already known medical compounds from willow bark, such as salicylic acid, the precursor to modern aspirin. The extract worked against two common types of virus with very different structures, enteroviruses and coronaviruses, suggesting the potential for a new broad-spectrum antiviral to help us fight viruses that are otherwise hard to treat. From a seasonal cold to a stomach bug, nobody likes catching a virus — and epidemics can be devastating. We need safe, sustainable antiviral options to treat the outbreaks of the future. Scientists in Finland have now shown that an extract of willow bark — a plant which has already provided several medicines, including the precursor to modern aspirin — has a broad-spectrum antiviral effect in cell sample experiments. The extract worked both on enveloped coronaviruses, which cause colds as well as Covid-19, and non-enveloped enteroviruses, which cause infections such as flu and meningitis. There are no clinically approved drugs which work against enteroviruses directly, so this extract could be a future game-changer. “We need broadly acting and efficient tools to combat […]

by Deborah Pirchner, Frontiers science writer Image: Shutterstock.com Fluctuations in sex hormones influence brain activity of the fear circuitry. A team of researchers in Canada has now examined the effects of oral contraceptive (OC) use on women’s brains. Their findings showed that ventromedial prefrontal cortex (vmPFC) thickness of women who were using OCs was reduced compared to men, suggesting a mechanism on how OC use could impair emotion regulation in women. Based on this study, this effect appears to be reversible after discontinuing use. More studies on impact and reversibility are needed, the researchers cautioned. More than 150 million women worldwide use oral contraceptives. Combined OCs (COCs), made up of synthetic hormones, are the most common type. Sex hormones are known to modulate the brain network involved in fear processes. Now a team of researchers in Canada has investigated current and lasting effects of COC use, as well as the role of body-produced and synthetic sex hormones on fear-related brain regions, the neural circuitry via which fear is processed in the brain. “In our study, we show that healthy women currently using COCs had a thinner ventromedial prefrontal cortex than men,” said Alexandra Brouillard, a researcher at Université du Québec […]

But with tens of thousands of articles published each year, it’s impossible to cover all of them. Here are just five amazing papers you may have missed. Carnivore territories might soon overlap – and some species profit more than others Some of Europe’s large carnivore populations, including jackals and lynxes, are growing and expanding their territories. The golden jackal, a wolf-like generalist that once occupied only the Balkan area, is currently expanding its territory. At the same time, the Eurasian lynx, a specialized predator previously hunted close to extinction, is slowly recovering. Writing in Frontiers in Ecology and Evolution, researchers have now modeled jackal and lynx distribution in Europe for current and future scenarios. Currently, it is estimated that the overlap of jackal and lynx territories is 13%. This overlap is likely to increase, given both species’ expansion. The researchers’ findings showed that both predators expanding their territories, leading to a dynamic where they coexist for the first time, may favor one species and threaten the other: Their predictions show an increase in habitat suitability for the golden […]

by Angharad Brewer Gillham, Frontiers science writer Image/Shutterstock.com Losing your sense of where you are can be fatal enough for aircraft pilots: spatial disorientation is a leading cause of fatal aircraft accidents. But losing your orientation in space itself is even more dangerous. Scientists have now developed wearable devices called vibrotactors that, combined with specialized training, improve people’s ability to fight spatial disorientation and could help astronauts correct themselves when their perceptions can no longer be relied upon. The sky is no longer the limit — but taking flight is dangerous. In leaving the Earth’s surface, we lose many of the cues we need to orient ourselves, and that spatial disorientation can be deadly. Astronauts normally need intensive training to protect against it. But scientists have now found that wearable devices which vibrate to give orientation cues may boost the efficacy of this training significantly, making spaceflight slightly safer. “Long duration spaceflight will cause many physiological and psychological stressors which will make astronauts very susceptible to spatial disorientation,” said Dr Vivekanand P. Vimal of Brandeis University in the United States, lead author of the article in Frontiers in Physiology. “When disoriented, an astronaut will no longer be able to rely […]

by Deborah Pirchner, Frontiers science writer Image: Shutterstock.com Many people experience stress, anxiety, and depressive symptoms in their life. Times of transition, such as pregnancy and children starting school can be significant periods of stress and vulnerability within families. Studies have generally found that high levels of anxiety and depression in parents are linked to poorer behavioral and cognitive outcomes in children. Now, a team of researchers in Canada has examined if self-reported paternal anxious and depressive symptoms are associated with children’s cognitive functioning and behavior. They found that slightly higher, but mild anxious or depressive symptoms in fathers were associated with fewer behavioral difficulties in the first years of elementary school and better scores on a standardized IQ testing in their children. The results need to be confirmed by further studies, the researchers said. While the role of mothers’ stress, anxiety and depression on children’s behavioral and cognitive development is well established, less is known about the connection between fathers’ mental health and children’s development. Now, a team of researchers affiliated to different institutions across Quebec, Canada has examined if paternal anxious and depressive symptoms, measured during their partner’s pregnancy, and again six to eight years later, are associated […]
