A handful of states around the world have pursued 'COVID zero' strategies. Through a combination of intensive lockdowns, travel restrictions and comprehensive test and trace systems, regions like Tonga, New Zealand, Taiwan, mainland China and Western Australia managed to keep the virus at bay. But now many of these countries are facing new outbreaks on a scale they have not yet seen, and it is being driven in part by vaccine hesitancy. In this episode of Coronapod we discuss how a successful public health campaign can breed new problems when it comes to public perception of risk, and ask how vaccine complacency might be avoided in the future.News: ‘COVID zero’ regions struggle with vaccine complacencySubscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.

As many countries start to ease or even remove COVID restrictions entirely, there are growing concerns from researchers that this will lead governments to take their eye off the ball and crucially stop collecting and reporting vital data. In this episode of Coronapod we discuss calls from two researchers to improve COVID testing and data reporting. What do they want done differently? Why does it matter?

00:47 G20 nations fail to cut emissions in COVID stimulus packagesThe G20 economies spent $14 trillion dollars on recovery packages to escape the global recession driven by the COVID-19 pandemic. Many governments made pledges to deliver emissions reductions as part of these packages. This week, a team of researchers have analysed the spending to see if these promises were kept.Comment: G20’s US$14-trillion economic stimulus reneges on emissions pledges09:34 Research HighlightsAn artificial nerve cell triggers a Venus flytrap’s snap, and a fossil shows that pterosaurs in the Jurassic period were larger than previously thought.Research Highlight: Venus flytrap snaps shut at synthetic neuron’s commandResearch Highlight: The surprisingly huge reptile that prowled the Jurassic skies12:10 How knowing a little about someone changes how anonymous you feelThis week, a team of researchers have used lab-based studies to show how learning a little about a stranger makes a person feel that the stranger knows something abo

Almost everything we do on the Internet is made possible by cryptographic algorithms, which scramble our data to protect our privacy. However, this privacy could be under threat. If quantum computers reach their potential these machines could crack current encryption systems — leaving our online data vulnerable.To limit the damage of this so called 'Q-day', researchers are racing to develop new cryptographic systems, capable of withstanding a quantum attack.This is an audio version of our feature: The race to save the Internet from quantum hackersNever miss an episode: Subscribe to the Nature Podcast on Apple Podcasts, Google Podcasts, Spotify or your favourite podcast app. Head here for the Nature Podcast RSS feed See acast.com/privacy for privacy and opt-out information.

Vaccine inequity continues to be one of the greatest challenges in the pandemic - with only 10% of those in low- and middle-income countries fully vaccinated. One of the biggest hold-ups is a lack of vaccine manufacturing capacity in poorer nations. But now, researchers at the WHO technology-transfer hub have completed the first step in a project aimed at building vaccine manufacturing capacity in the Global South, by successfully replicating Moderna's COVID vaccine without assistance from the US-based biotech company. In this episode of Coronapod, we ask how they did it? What happens next? What the legal ramifications might be and what this could mean for the future of vaccine manufacture in low- and middle-income countries?

The word endemic is often mistakenly used to describe a rosy end to the pandemic where COVID-19 becomes a mild, but ever-present infection akin to the common cold. But this is by no means guaranteed and the reality could be much less favourable.

Much of the coverage of COVID immunity often focuses on antibody response and for good reason - these small, y-shaped proteins can detect, and in some cases neutralise, viruses like SARS-CoV-2. But as variants like Omicron evolve to evade antibodies, the role of another part of the immune system, T cells, has been brought into sharper focus. These immune cells work in a different way to antibodies, attacking infected cells rather than the virus itself, which can make their response broader and more robust. Now, research is showing that, unlike antibodies, T cell potency is not impacted by the mutations in variants like Omicron. In this episode of Coronapod, we ask why T cells are so often overlooked, and what role they might be playing in our protection from the coronavirus.News:‘Killer’ immune cells still recognize Omicron variantSubscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.

The burgeoning field of precision public health is a tech-centric approach that looks to target public-health interventions to the specific people who need them.Precision approaches are taking off and its advocates say this concept promises to save money and lives. However, other researchers are concerned that as funders provide huge amounts of money for precision-public-health initiatives, the focus will be taken away from conventional public health approaches that could improve the lives of millions.This is an audio version of our feature: Is precision public health the future — or a contradiction?

As of January 2022, the WHO reports that 5.5 million people have lost their lives to the pandemic. However, many research groups suggests that this number is likely to be a significant underestimate, although it is hard to be certain as counting mortality across the world is an exceptionally difficult task. In this episode of Coronapod we ask why, and delve into the range of approaches scientists are taking to try to get to the bottom of the sticky problem - from excess death counts, to machine learning and even satellite imagery.News Feature: The pandemic’s true death toll: millions more than official countsSubscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.
