In a quickly developing story a new variant, first detected in Botswana, is triggering rapid action among researchers. The variant - currently named B.1.1.529 has more than 30 changes to the spike protein - and the concern is that these mutations may result in increased transmissibility, severity of disease or even antibody evasion.In this episode of Coronapod, we discuss what we know so far, how scientists are searching for answers and what this could mean for the pandemic.News: Heavily mutated coronavirus variant puts scientists on alert  See acast.com/privacy for privacy and opt-out information.

Spineless sea squirts shed light on vertebrate evolution, and an iodine-fuelled engine powering a satellite in space.In this episode:00:45 A story of sea squirts, ancient vertebrates and missing genesWhen a PhD student set out to study the developmental pathways of a strange sea creature, he hoped to shed light on the origins of vertebrate animals. Instead, researchers found themselves investigating a strange case of missing genes. We hear why gene loss could be a more significant factor in evolutionary processes than was previously thought.Research article: Ferrández-Roldán et al.08:17 Research HighlightsThe unusual crystal that gives a beetle its glittering green sheen, and the genetics of a fish’s 200 year lifespan.Research Highlight: Weird crystal makes beetle a living jewelResearch Highlight: Some of Earth’s longest-lived fish show how to reach extreme ages10:43 An iodine-fuelled engine for satellitesIn space, many satellites use xenon-fuelled ‘electric propulsion systems’ to maneuver. However, xenon is rare and requires high-pressure storage systems, so researchers have been working to develop alternative fuels. This week, a team publish details of the first in-space test of an iodine-powered electric propulsion system, which they say has many advantages over xenon systems.Research article: Rafalskyi et al16:37 Briefing ChatWe discuss some highlights from the Nature Briefing.

Two new anti-viral pills have been shown to be safe and effective against COVID in clinical trials, according to recent press releases. The drugs, molnupiravir, developed by Merck and Ridgeback Biotherapeutics, and Paxlovid, developed by Pfizer both appear to significantly reduce hospitalisation in people with early COVID. Some researchers are quietly hopeful that these new weapons in the anti-COVID arsenal could have a big impact, in particular in parts of the world where vaccines are still not widely available, but there are a number of caveats. In this episode of Coronapod, we open the pill boxes and pick through the contents - asking how the drugs work, what side effects we might see and how, if at all, they might change the course of the pandemic.News: COVID antiviral pills: what scientists still want to know﻿﻿Subscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.  See acast.com/privacy for privacy and opt-out information.

Reassessing 24,000 years of global temperatures, and on the ground at COP26.In this episode:01:21 Reassessing Earth’s climate over the past 24,000 yearsThe ~20,000 year period from the Last Glacial Maximum to the pre-industrial era saw huge changes to the Earth’s climate. But characterising how temperatures changed during this time has been difficult, with different methods producing different results. Now, a team have combined two techniques, which they hope will provide new insights into the past, and future, of Earth’s climate.Research article: Osman et al.News and Views: Global temperature changes mapped across the past 24,000 years09:53 COP26 Briefing ChatThe United Nations’ climate change conference COP26 continues this week.

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?  See acast.com/privacy for privacy and opt-out information.

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.  See acast.com/privacy for privacy and opt-out information.

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.

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.
