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.

00:45 Working out how the ability to digest milk spreadHumans have been drinking milk for thousands of years, but it seems that they were doing so long before the ability to digest it became prevalent. Then around 2000 years ago, this ability became common in Europe, presenting a mystery to researchers – why then?

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. In this episode of Coronapod, we discuss the paper and ask how a system like this could help countries around the world respond to the COVID pandemic and beyond.News: COVID variants found in sewage weeks before showing up in tests Hosted on Acast.

Despite the devastating loss of life caused by COVID-19, some researchers are arguing that the longest lasting impact of the pandemic will be on education. UN agencies calculate that more or less all school students on the planet - 1.6 billion - have faced an average of 4.5 months of school closures owing to the pandemic, the largest disruption to education in history. Teachers have been under immense pressure to keep their students happy and learning, but it is an uphill battle.

Millions of people around the world have been left managing the complex and amorphous syndrome that is long COVID. But the underlying cause of this myriad of symptoms is not clear. One hypothesis is that the virus is able to find a safe haven in the body from which it can bide its time and potentially re-emerge - a viral reservoir. Now researchers studying long COVID have found evidence of SARS-CoV-2 in a series of organs around the body, most notably the gut, months after the infection appears to have been cleared from the respiratory system. While there is still a long way to go before the reservoir hypothesis can be confirmed, these data provide compelling new support for the theory. In this episode of Coronapod, we discuss how the studies were carried out, why the question of long COVID's cause is so difficult to crack, and what more needs to be done to get a firm answer.News: Coronavirus ‘ghosts’ found lingering in the gut Subscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.

The true disability cost of the COVID-19 pandemic is still unknown, but more and more studies are adding to the list of potential fallout from even mild COVID 19 infection. In this episode of Coronapod we discuss a massive association study which links COVID-19 cases with an increase in the risk of developing type 2 diabetes.

00:56 How video calls can reduce creativityAs a result of the pandemic, workers around the world have become accustomed to meeting colleagues online. To find out if this switch from face-to-face meetings came at a cost to creativity, a team compared the number of ideas generated by workers collaborating either online, or in-person. They showed that people meeting virtually produced fewer creative ideas than those working face-to-face, and suggest that when it comes to idea generation maybe it’s time to turn the camera off.Research article: Brucks & LevavNews and Views: Virtual collaboration hinders idea generationVideo: Why video calls are bad for brainstorming08:08 Research HighlightsFragments from an ancient pyramid suggest earliest known use of a Maya calendar, and how sweet snacks could damage rare iguanas’ metabolism.Research Highlight: Deer symbol hints at early adoption of Maya calendarResearch Highlight: Tourists’ sweet treats threaten rare iguanas’ health10:34 Fish skin reveals a new type of cell divisionResearchers looking at the skin cells of zebrafish have discovered a new type of cell division, which doesn’t require DNA replication.

One potential solution has been to store this energy as heat before converting it back into electricity, but to date this process has been inefficient.
