Researchers isolate the protein thought to allow birds to sense magnetic fields, and astronomers pinpoint the stars that could view Earth as an exoplanet.In this episode:00:45 Homing in on the molecule that helps birds find their way.How migratory birds sense magnetic fields is a long standing mystery in sensory biology. Now researchers have isolated a molecule, found within the eyes of these birds, which might act as a compass using quantum mechanics.Research paper: Xu et al.07:28 Research HighlightsHow spending time on land boosts the brainpower of amphibious fish, and the neural pathway of sneezing has been revealed.Research Highlight: Amphibious fish get smart — by working out on landResearch Highlight: How the brain makes us go ‘Achoo!’09:52 Exoplanet EarthAstronomers have catalogued almost 2,000 stars from which the Earth could be detected passing in front of the Sun. The team suggest that these stars would be good targets to search for planets that could harbour life.Research Article: Kaltenegger & Faherty18:46 Briefing ChatWe discuss some highlights from the Nature Briefing.

After a slew of wildly successful vaccine trials, this week marked a more underwhelming result. The third mRNA vaccine to complete phase three trials, developed by CureVac, is just 47% effective at staving off disease according to preliminary data. This is a stark contrast with previous mRNA vaccines from Moderna and Pfizer BioNtec which returned around twice that efficacy in their trials. In this episode of Coronapod, we ask why the CureVac vaccine has faltered, and what this might mean for the future of the pandemic and mRNA vaccine development.News: CureVac COVID vaccine let-down spotlights mRNA design challengesNews Feature: How COVID unlocked the power of RNA vaccinesSubscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.

The pros and pitfalls of collaboration, with insights from researchers and beyond.This week, Nature has a special issue on collaborations, looking at the benefits to science and society that working together can bring. In this collaboration-themed edition of the podcast, we’re joined by Nature’s David Payne to discuss the issue, and the state of research collaborations in the wake of the COVID-19 pandemic.In this episode:02:49 How are research collaborations changing?To answer the biggest questions, research teams are coming together in larger numbers than ever before. But the scientific enterprise hasn’t been set up to support or reward team efforts. We look at how funding systems and methods for giving research-credit need to adapt, to match the reality of modern science.Feature: How the COVID pandemic is changing global science collaborationsCareers Feature: The authorship rows that sour scientific collaborationsCareers Feature: ‘We need to talk’: ways to prevent collaborations breaking down16:45 Community-research collaborationsIn order to do research that can help communities, scientists need to develop relationships with community members.

The global burden of COVID-19 has predominantly been measured using metrics like case numbers, hospitalisations and deaths. But the long term health impacts are more difficult to capture. In this episode of Coronapod we discuss one way that public health experts are trying to get to grips with the problem using metrics such as disability adjusted life years (DALYs) and quality adjusted life years (QALYs).As new data suggests that COVID could leave millions with lasting disability or ill-health, we ask how changing the lens through which we asses the impacts of COVID could change public health policies, the perception of risk and even the behaviour of individuals.News Feature: The four most urgent questions about long COVIDComment: Count the cost of disability caused by COVID-19Subscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.

Since the beginning of the pandemic, there have been allegations that SARS-CoV-2 could have originated in a Chinese lab. A phase one WHO investigation concluded that a 'lab-leak' was "extremely unlikely" and yet, the theory has seen a resurgence in recent weeks with several scientists wading into the debate.In this episode of Coronapod, we delve into what scientists have been saying and ask how and why the 'lab-leak' hypothesis has gained so much traction. We ask if the way we communicate complex and nuanced science could be fuelling division, and what the fallout could be for international collaboration on ending the pandemic.News: Divisive COVID ‘lab leak’ debate prompts dire warnings from researchersScience: Investigate the origins of COVID-19Subscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.
