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 Hosted on Acast.

00:47 Pinpointing the season when an asteroid wiped out the dinosaursAround 66 million years ago, an enormous asteroid struck the Earth, leading to the end of the time of the dinosaurs. In a new paper, a team of scientists looked at evidence from fossilised fish, and suggest it happened in springtime in the Northern Hemisphere.Research article: During et al.08:42 Research HighlightsTransparency shrinks the gender pay-gap in academia, and how Tutankhamen’s meteorite-metal dagger was forged.Research Highlight: Gender pay gap closes after salary information goes publicResearch Highlight: How a space rock became King Tut’s dagger11:01 How climate change is affecting nighttime wildfiresCool, damp nights are a critical barrier to fire progression around the world. But a recent study has revealed that the duration and intensity of nighttime fires has increased in many places, as a result of climate change. The researchers say this trend is likely to continue, hampering efforts to control blazes.Research article: Balch et al.18:56 Briefing ChatWe discuss some highlights from the Nature Briefing.

Scientists scramble to understand the devastating Tongan volcano eruption, and modelling how societal changes might alter carbon emissions.In this episode:00:46 Understanding the Tongan eruptionOn the 15th of January, a volcano in the South Pacific Ocean erupted, sending ash into the upper atmosphere, and unleashing a devastating tsunami that destroyed homes on Tonga’s nearby islands. Now scientists are trying to work out exactly what happened during the eruption — and what it means for future volcanic risks.News Feature: Why the Tongan eruption will go down in the history of volcanology08:49 Research HighlightsThe genes associated with reindeers’ roaming behaviour, and how fossilised puke has thrown up new insights into pterosaurs’ stomachs.Research Highlight: A reindeer’s yearning to travel can be read in its genesResearch Highlight: Petrified puke shows that ancient winged reptiles purged11:29 Modelling societal changes to carbon emissionsA team of researchers have modelled what humans might do in the face of climate change, and looked at how societal, political and technological changes could alter future emissions.Research article: Moore et al.18:12 Briefing ChatWe discuss some highlights from the Nature Briefing.

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? Both during the pandemic and beyond.News: South African scientists copy Moderna's COVID vaccineNews: The fight to manufacture COVID vaccines in lower-income countriesEditorial: Africa is bringing vaccine manufacturing homeSubscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.

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. In this episode of Coronapod we get the evolutionary virologist's take - asking what endemicity might really look like, and what control we still have in shaping the future of SARS-CoV-2.World View: COVID-19: endemic doesn’t mean harmlessSubscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.

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?
