00:46 A new test to get autonomous vehicles on the roadTruly autonomous vehicles, ones that don't require a driver to be present and are driven by AI, aren't yet safe for public use. Part of the reason for this is it has been difficult to train them to deal with rare dangerous situations. Now researchers are unveiling a new approach to present lots of these infrequent events to the AI very rapidly, speeding up the training and testing process.Research Article: Feng et al.News and Views: Hazards help autonomous cars to drive safelyVideo: The driving test for driverless cars08:23 Research HighlightsHow bird-flu is adapting to mammals, and the effect of negative headlines.Research Highlight: Bird-flu virus makes itself at home in Canada’s foxes and skunksResearch Highlight: It’s bad! Awful! Negative headlines draw more readers10:43 Why bat research is taking offBats are known to tolerate a lot of viruses that are deadly to humans without much issue. With the ongoing pandemic, this has driven researchers to dive more into the world of bats in the hopes of applying bats' tolerance to humans. Reporter Smriti Mallapaty has been writing about this renewed interest and she joined us to tell us more.News Feature: Bats live with dozens of nasty viruses — can studying them help stop pandemics?

00:47 An edited genetic code that prevents viral infectionResearchers have engineered bacteria with synthetic genomes to be immune to viral infection. The team streamlined the bacteria’s genetic code, and re-engineered the protein-producing machinery to insert the wrong amino acid if used by a virus, effectively making the bacteria ‘speak’ a different language to any invaders. It’s hoped that this technique could be used to reduce unwanted sharing of genes from modified organisms.Research article: Nyerges et al.News & Views: Synthetic bacterial genome upgraded for viral defence and biocontainment07:42 Research HighlightsEstimating the methane output of an enormous wetland ecosystem, and how honeybees improve their dance moves with a little help from their elders.Research Highlight: Methane from one of Earth’s largest wetland complexes is set to soarResearch Highlight: Watch them waggle: bees dance better after lessons from elders10:02 How mini-MRI scanners could improve access to imagingMagnetic resonance imaging is a standard technique in clinical care. However many people, particularly those living in low- and middle-income countries have limited access to this technology. To address this, new types of smaller MRI scanners are being designed that are more affordable and practical for use in rural settings or small clinics. We hear from a researcher working on one of these systems about ways improve them and ensure they are available to all.Comment: Five steps to make MRI scanners more affordable to the world18:11 Briefing ChatWe discuss some highlights from the Nature Briefing.

00:47 Wildfire smoke’s chemical composition enhances ozone depletionSmoke from the devastating Australian wildfires of 2019-2020 led to a reduction in ozone levels in the upper atmosphere, but it’s been unclear how. Now, a team proposes that smoke’s particulate matter can enhance the production of ozone depleting chemicals, matching satellite observations during the Australian fires. The results spark concerns that future wildfires, which are set to grow more frequent with ongoing climate change, will undo much of the progress towards restoration of the ozone layer.Research article: Solomon et al.News & Views: How wildfires deplete ozone in the stratosphere08:27 Research HighlightsA global analysis of bats reveals the species most likely to be hunted by humans, and the stem cells that allow deer antlers to regrow.Research Highlight: Big bats fly towards extinction with hunters in pursuitResearch Highlight: Mice grow ‘mini-antlers’ thanks to deers’ speedy stem cells10:53 Modelling food systems with ‘digital twins’Recent global crises have highlighted the fragility of the interconnected systems involved in getting food from farm to fork. However, siloed datasets have made it hard to predict what the exact impacts of these events will be. In a World View for Nature, researcher Zia Mehrabi argues that precise virtual models like those used in the aerospace industry should be developed for food systems. These so-called ‘digital twins’ could inform global food policy before emergencies unfold.World View: Sims-style ‘digital twin’ models can tell us if food systems will weather crises18:17 Briefing ChatWe discuss some highlights from the Nature Briefing.

00:47 How a racing heart could trigger anxietyAnxiety can make the heart beat faster, but could the reverse be true as well? That question has been much debated, but hard to test. Now, a team has shown that artificially increasing a mouse’s heart rate can induce anxiety-like behaviours, and identified an area in the brain that appears to be a key mediator of this response. They hope that this knowledge could help to improve therapies for treating anxiety-related conditions in the future.Research article: Hsueh et al.News & Views: How an anxious heart talks to the brain08:32 Research HighlightsThe chance discovery of the smallest rock seen so far in the Solar System, and the first brain recording from a freely swimming octopus.Research Highlight: Asteroid photobombs JWST practice shotsResearch Highlight: How to measure the brain of an octopus10:57 How NASA’s DART mission beat expectiationsIn September 2022, NASA’s DART spacecraft smashed into a space rock known as Dimorphos, which orbits a near-Earth asteroid.

Twitter has become indispensable to many scientists. It is a place to share findings, raise their profile, and is even used as a source of data in many studies.In recent months though, the site has been in turmoil after a swathe of policy changes in light of Elon Musk's takeover. Never a stranger to misinformation and abuse, these problems have reportedly gotten worse. Additionally, the ability to use Twitter as a source of data is in peril, and malfunctions are more commonplace.In this episode of Nature's Take we discuss how these changes are affecting the platform and the knock-on effects on science.

Imprinting is a quirk of the immune system in which someone’s initial exposure to a virus biases their immune response when they meet the same virus again.Studies are showing how imprinting shapes people’s responses to SARS-CoV-2; those infected with earlier strains can mount weaker responses to a later Omicron infection.This phenomenon is dampening the hope that variant-tailored boosters will markedly reduce transmission of the virus, although researchers agree that variant-tailored boosters are worth getting because they still provide some immunity, and prevent serious illness.This is an audio version of our Feature: How your first brush with COVID warps your immunity Hosted on Acast.

00:45 A new microscope to look for ‘magic’ anglesTo better visualise how electrons are ‘moving’ in materials, a team have developed the Quantum Twisting Microscope. This instrument puts two 2D layers of atoms into close contact, allowing them to interact, which can give useful information about their properties. The microscope can also rotate one of the layers, helping researchers look for so-called ‘magic angles’, where 2D materials like graphene can exhibit extraordinary properties.Research article: Inbar et al.News & Views: A twist in the bid to probe electrons in solids09:55 Research HighlightsHow an extinct insect larvae’s prodigiously long ‘neck’ may have helped it hunt, and surveying the levels at which coastal cities are converting water into land.Research Highlight: Extinct insects hunted like predatory giraffesResearch Highlight: Cities worldwide claw vast amounts of land from the sea12:21 How Russia’s invasion has affected science in UkraineThis week marks the first anniversary of Russia’s invasion of Ukraine.

00:47 A metadevice for faster electronicsIn the past, increasing the speeds of electronics required designing smaller components, but further reductions in size are being hampered by increasing resistance. To get around this, researchers have demonstrated a ‘metadevice’, which prevents resistance building up by concentrating the flow of signals into specific regions of the device. The hope is that this meta-method could be used to create even smaller electrical components in the future.Research article: Nikoo & Matioli06:27 Research HighlightsHow waiting times for services are higher for people in the US with low incomes, and how your brain hears an alarm while you’re asleep.Research Highlight: Who wastes more time waiting?

There is much concern that these trends are linked, but hard evidence has been hard to come by. So how can scientists get a better understanding of what’s going on? In a Comment article for Nature, researchers argue that, rather than lumping ‘young people’ into one homogeneous group, future studies should consider where they are in terms of their development, as this could influence the potential impacts of social media use.Comment: How social media affects teen mental health: a missing link19:52 Briefing ChatWe discuss some highlights from the Nature Briefing.

0:46 The mysterious ring in the distant Solar SystemQuaoar is a small, rocky object that lies beyond Neptune’s orbit. In an unexpected discovery, researchers have shown that this object has its own orbiting ring, similar to those seen encircling planets like Saturn. However, Quaoar’s ring shouldn’t exist, as it is at a distance far outside the theoretical limit at which rings are thought to be stable, and researchers are trying to figure out why.Research article: Morgado et al.News and Views: A planetary ring in a surprising place07:01 Research HighlightsA repurposed skin-disease drug suppresses alcohol consumption in people with alcohol-use disorder, and how volcanic eruptions may have contributed to social unrest in ancient Egypt.Research Highlight: Pill for a skin disease also curbs excessive drinkingResearch Highlight: Volcanic quartet linked to bad times in ancient Egypt09:26 Air pollutionExposure to polluted air has been linked to millions of deaths each year.

00:45 Inert ant pupae produce a previously unobserved fluidAnt larvae metamorphose into adults by pupating. It was assumed that these inert pupae don’t play a role in the wider ant colony, but a team of researchers have found that they actually secrete a fluid that is consumed by both adult ants and larvae. This fluid is rich in proteins and metabolites, and appears to be an important source of larval nutrition.

00:46 How flies can move their eyes (a little)It's long been assumed flies’ eyes don’t move, and so to alter their gaze they need to move their heads. Now, researchers have shown that this isn’t quite true and that fruit flies can actually move their retinas using a specific set of muscles, which may allow them to perceive depth. The team also hope that this movement may provide a window into some of the flies’ internal processes.Research article: Fenk et al.08:54 Research HighlightsHow the 80-year-old wreck of a sunken warship is influencing ocean microbes, and tracing an epilepsy-related gene variant back to a single person from 800 years ago.Research Highlight: A ship sunk during the Second World War still stirs up the seabedResearch Highlight: Families on three continents inherited their epilepsy from a single person11:11 Calls to mandate militaries’ emissions reportingThe eyes of the world will be focused on the UN’s upcoming COP27 conference to see what governments will pledge to do to reduce global emissions.

When COVID-19 hit it didn't kill indiscriminately. In the US, being Black, Hispanic, or Native American meant you had a much greater risk of death than if you were white. And these disparities are mirrored across the world.In this episode we explore the complex tale behind this disparity. Throughout history, racism and biases have been embedded within medical technology, along the clinicians who use it. Cultural concepts of race have been falsely conflated with biology. The way medicine is taught, has reinforced flawed stereotypes. Disease itself, has been racialised. All of this adds up to barriers to care and worse health outcomes for many people, just because of the colour of their skin.Science and scientists have played an influential part in embedding such racism into medicine But by challenging received wisdom science too has the power to right wrongs, and work towards solutions.Read more of Nature's coverage of racism in science.Click here for our list of sources Hosted on Acast.

At the beginning of the COVID-19 pandemic, many countries introduced strict lockdowns to help prevent spread of the disease. Since then, researchers have been studying the effects of these measures to help inform responses to future crises.Conclusions suggest that countries that acted swiftly to bring in strict measures did best at preserving lives and their economies, but analysing the competing costs and benefits of lockdowns has been tough, as this work often comes down not to scientific calculations, but value judgements.This is an audio version of our Feature: What scientists have learnt from COVID lockdowns Hosted on Acast.

The development of brain chimaeras – made up of human and animal neurons – is an area of research that has hugely expanded in the past five years. Proponents say that these systems are yielding important insights into health and disease, but others say the chimeras represent an ethical grey zone, because of the potential to blur the line between humans and other animals, or to recapitulate human-like cognition in an animal.This is an audio version of our Feature: Hybrid brains: the ethics of transplanting human neurons into animals Hosted on Acast.

In this first episode of Nature's Take, we get four of Nature's staff around microphones to get their expert take on preprints. These pre-peer-review open access articles have spiked in number over recent years and have cemented themselves as an integral part of scientific publishing. But this has not been without its issues.In this discussion we cover a lot of ground. Amongst other things, we ask whether preprints could help democratise science or contribute to a loss of trust in scientists. We pick apart the relationship between preprints and peer-reviewed journals and tackle some common misconceptions. We ask how preprints have been used by different fields and how the pandemic has changed the game. And as we look to the future, we ask how preprints fit into the discussion around open access and even if they could do away with journals all together. Hosted on Acast.

Cold exposure in mice activates brown fat to deny tumours glucose, and the future of extreme heatwaves. 00:45 How cold temperatures could starve tumoursA team of researchers have found that exposing mice to the cold could starve tumour cells of the blood glucose they need to thrive. They showed that the cold temperatures deprived the tumours of fuel by activating brown fat – a tissue that burns through glucose to keep body temperature up. The team also showed preliminary evidence of the effect occurring in one person with cancer, but say that more research is needed before this method can be considered for clinical use.Research article: Seki et al.08:59 Research HighlightsEvidence of the world’s southernmost human outpost from before the Industrial Revolution, and how jumping up and down lets canoes surf their own waves.Research Highlight: Bones and weapons show just how far south pre-industrial humans gotResearch Highlight: How jumping up and down in a canoe propels it forwards11:24 The future of extreme heatwavesClimate scientists have long warned that extreme heat and extreme heatwaves will become more frequent as a result of climate change.

Inequity has been a central feature of the COVID19 pandemic. From health outcomes to access to vaccines, COVID has pushed long-standing disparities out of the shadows and into the public eye and many of these problems are global. In this episode of Coronapod we dig into a radical new collaboration of 15 countries - co-led by the WHO, and modelled on open-science. The project, called the mRNA vaccine technology transfer hub, aims to create independent vaccine hubs that could supply the global south, and take on the giants of the pharmaceutical industry in the process. But the road ahead is long - the challenges are complex and numerous, and the odds are stacked against them. But at a time when stakes couldn't be higher, momentum is building and if successful, the tantalising possibility of an end to a dangerous legacy of dependence looms. Can it be done? And if so, what needs to change to make it happen? We ask these questions and more.News Feature: The radical plan for vaccine equityThis project was supported by the Pulitzer Center. Hosted on Acast.

Since early in the pandemic, scientists have searched for signals of SARS-CoV-2 transmission by sampling wastewater. This surveillance method has provided vital information to inform public health responses. But the approach has never been particularly specific - pointing to broad trends rather than granular information such as which variants are spreading where. But now a team from the University of California have created two new tools to sample waste water in much greater detail - and spot variants and their relative concentrations up to two weeks faster than testing-based surveillance methods.
