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.
