Lake Kivu, nestled between the Democratic Republic of the Congo and Rwanda, is a geological anomaly that holds 300 cubic kilometres of dissolved carbon dioxide and 60 cubic kilometres of methane.The lake has the potential to explosively release these gases, which could fill the surrounding valley, potentially killing millions of people.Researchers are trying to establish the likelihood of such an event happening, and the best way to safely siphon the gases from the lake.This is an audio version of our feature: How dangerous is Africa’s explosive Lake Kivu?

More that 3 billions doses of China's CoronaVac and Sinopharm vaccines have been administered across the globe, playing an especially important role in Latin America and South East Asia, as well as China. These vaccines use inactivated virus particles to expose the immune system to Sars-CoV-2, but they do not appear to generate the same levels of neutralising antibodies as other vaccine platforms such as those based on mRNA. Now studies are suggesting that this protection may be waning more quickly than with other vaccines, which has sparked a conundrum - in many countries the only vaccines available are CoronaVac or Sinopharm. In this episode of Coronapod we ask how researchers are trying to get a handle on what is going on and how they might adapt to counteract waning immunity from these crucial vaccines.News: China’s COVID vaccines have been crucial — now immunity is waningSubscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.

The unexpected origins of a 4000-year-old people, protecting your ‘digital presence’ and what to expect from COP26.In this episode:00:48 The origins of the mysterious Tarim mummiesFor decades there has been debate about the origins of a group of 4000-year-old individuals known as the Tarim Basin mummies. Their distinct appearance and clothing has prompted scientists to hypothesise they had migrated from the North or West. Now, a team of researchers have used modern genomics to shed new light on this mystery and reveal that migration was not the mummies’ origin.Research article: Zhang et al.News and Views: The unexpected ancestry of Inner Asian mummies08:59 Research HighlightsMaking wood mouldable, and how ancient snakes diversified their diets.Research Highlight: Moulded or folded, this wood stays strongResearch Highlight: Finicky no more: ancient snakes ate their way to success11:09 How a regular ‘digital-hygiene’ check can protect your reputationAttaching a researcher’s name to a paper without them knowing is an unscrupulous practice that can have serious repercussions for the unwitting academic.

People that have recovered from COVID are seeing stronger immune responses after vaccination than those that never contracted the virus. Researchers are now racing to unpick what is behind this powerful 'hybrid immunity'.

New data suggests that inexpensive, high-efficiency particulate air (HEPA) filters can effectively scrub SARS-CoV-2 particles from the air in hospital COVID wards. The result validates previous studies carried out in controlled conditions. Currently, HEPA filters are not routinely used in hospital settings, but researchers suggest they could could help mitigate the risk of tramission of airborne viruses.In addition a new study has demonstrated the effectiveness of mask wearing, with surgical masks proving more effective than those made of cloth. The trial, which involved 350,000 participants in Bangladesh, is the latest in a long line of studies demonstrating mask efficacy - but this is the first randomised control trial of its kind. We ask if this gold-standard trial will prove to be the final word on the effectiveness of masks.News: Real-world data show that filters clean COVID-causing virus from airNews: Face masks for COVID pass their largest test yetSubscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.
