  • Coronapod: the COVID scientists facing violent threats
    Hundreds of scientists have responded to a survey asking about harassment and abuse during the pandemic. The results paint a picture which is as concerning as it is shocking. In this episode of Coronapod we discuss the kinds of abuse scientists are facing, try to pick apart where it is comes from and ask what can be done about it?News Feature: ‘I hope you die’: how the COVID pandemic unleashed attacks on scientistsCareers feature: Real-life stories of online harassment — and how scientists got through itSurvey data tableSubscribe 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.

  • How electric acupuncture zaps inflammation in mice
    The neurons behind acupuncture’s effect on inflammation, and how antibiotics affect gut bacteria.In this episode:00:54 The neuronal basis for acupuncture’s effect on inflammationIn mice, electroacupuncture has been shown to reduce inflammation, but only when certain points on the body are stimulated. Why this is has puzzled scientists, but now, researchers have identified the specific neurons that are involved. They hope that this knowledge could be used in future to help treat certain inflammatory-related diseases.Research article: Liu et al.News and Views: Electroacupuncture activates neurons to switch off inflammation07:28 Research HighlightsThe Aztec origins of an obsidian ‘spirit mirror’, and the damage done by a Soviet plutonium complex.Research Highlight: A ‘spirit mirror’ used in Elizabeth I’s court had Aztec rootsResearch Highlight: Cold-war spy pictures reveal a Soviet nuclear ‘cloud generator’10:18 Assessing antibiotics’ collateral damage.Antibiotics are known to cause damage to the communities of bacteria that live in our guts. To better understand why this happens, a team has mapped the effects that different antibiotics have on individual gut-bacteria species, which may offer new insights into preventing this collateral damage.Research article: Maier et al.17:32 Briefing ChatWe discuss some highlights from the Nature Briefing.

  • Coronapod: new data affirms the benefits of air filters and masks
    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.  See acast.com/privacy for privacy and opt-out information.
