Addressing the problem of sudden food scarcity in US cities, and the up-and-coming field of computational social science.In this episode:00:45 Food shocksClimate change, the COVID-19 pandemic, and geopolitical crises can cause food shortages. To tackle this issue, Alfonso Mejia and colleagues have modelled how to best mitigate these food shocks in US cities. Alfonso tells us about the new analyses and what steps cities could take in the future.Research Article: Gomez et al.News and Views: How to buffer against an urban food shortage06:07 Research HighlightsA tiny lattice can withstand the impacts of projectiles at twice the speed of sound, and the neurons that allow humans to perceive time.Research Highlight: Supersonic strikes leave just a dent in this super-light materialResearch Highlight: The ‘time neurons’ that help the brain keep track08:25 Computational Social ScienceBig data is transforming research, and social science is no exception.

Since the beginning oft he pandemic, researchers have searched for a biomarker which indicates immune protection from COVID-19 known as a correlate of protection. Now, the team developing the Oxford–AstraZeneca COVID-19 vaccine have published the first results of their so-called 'breakthrough study' which indicated puts forwards thresholds of neutralising antibodies that they suggest correlate with protection. The hope is that, should these results be confirmed, such biomarkers could speed up the development of new vaccines, and provide better ways to monitor the efficacy of tweaked vaccine aimed at fighting variants.News: Scientists identify long-sought marker for COVID vaccine successSubscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.

A deluge of trials has stress-tested the systems that produce evidence.Around the world, researchers have raced to test therapies to treat COVID-19. The speed and urgency of this task has revealed both the weaknesses in the collection and use of research-based evidence, and how well-run trials have helped save lives.This is an audio version of our feature: How COVID broke the evidence pipeline Hosted on Acast.

Early vaccine trials did not include pregnant or breastfeeding people which left some people asking whether COVID vaccines are safe and effective for those who are breastfeeding. The latest data suggests that they are and in this episode of Coronapod we dig into the questions scientists have been asking. Could the vaccine make it into breastmilk? Can COVID antibodies be transferred to a breastfeeding child? And if so, how?News Feature: COVID vaccines and breastfeeding: what the data saySubscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.

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.

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.

Understanding precisely which sections come into contact has been difficult, but now a new technique is helping to reveal them at an individual base-pair level.Research paper: Hua et al.15:22 Briefing ChatWe discuss some highlights from the Nature Briefing.
