A new generation of anti-obesity medications are displaying striking results: drastically diminishing weight, without the serious side effects of previous medications.These drugs have raised hopes the weight can be pharmacologically altered in a safe way, but some researchers are concerned about the drugs' high cost, and that these medications could feed into some societies' obsessions with thinness.This is an audio version of our Feature: The ‘breakthrough’ obesity drugs that have stunned researchers Hosted on Acast.

00:45 The role of serine in diabetic neuropathyNerve damage is a common complication of diabetes, and can even lead to limb amputation. Thus far, the only way for people to slow its onset is by managing their diet and lifestyle. Now though, research in mice shows how the amino acid serine may be key to this nerve damage, suggesting a potential role for the molecule in future therapeutics.Research article: Handzlik et al.News and Views: Serine deficiency causes complications in diabetes06:47 Research HighlightsDNA from chickens is spreading to their wild relatives, and a hidden magma chamber is revealed beneath an underwater volcano.Research Highlight: Chickens’ DNA is fouling the genomes of their wild relativesResearch Highlight: Underwater volcano near Greece is a sleeping menace09:05 Briefing ChatWe discuss some highlights from the Nature Briefing.

In this episode:00:45 Laser-guided lightningScientists have shown that a specially designed laser can divert the course of lightning strikes in a real-world setting. The team fired the laser into the sky above a communications tower high in the Swiss Alps and altered the course of four strikes. In future they hope that this kind of system could be used to protect large infrastructure, such as airports.Research article: Houard et al.News: This rapid-fire laser diverts lightning strikes09:36 Research HighlightsThe crabs that lean on bacteria to detoxify sulfur from hydrothermal vents, and how a persons’ nasal microbes might exacerbate their hay fever.Research Highlight: Crabs endure a hellish setting — with help from friendsResearch Highlight: Plagued by hay fever?

In this episode:00:53 How virtual meetings can limit creative ideasIn April, we heard how a team investigated whether switching from face-to-face to virtual meetings came at a cost to creativity. They showed that people meeting virtually produced fewer creative ideas than those working face-to-face, and suggest that when it comes to idea generation maybe it’s time to turn the camera off.Nature Podcast: 27 April 2022Research article: Brucks & LevavVideo: Why video calls are bad for brainstorming08:29 How the Black Death got its startThe Black Death is estimated to have caused the deaths of up to 60% of the population of Europe.
