Description

In this episode:00:47 The brain-computer interfaces that help restore communicationPeople with certain neurological conditions can lose the ability to speak as a result of facial paralysis. This week, two teams demonstrate the potential of devices called brain-computer interfaces to help people in these situations communicate. These interfaces work by identifying the brain activity associated with the intent to say words, and converting this activity into speech-related outputs, such as text or audio. Both devices show marked improvements compared with previous interfaces, and show that the technology could represent a way to help restore communication to people with severe paralysis.Research article: Metzger et al.Research article: Willett et al.News and Views: Brain implants that enable speech pass performance milestones11:46 Research HighlightsHow wind-tunnel experiments could help athletes run the fastest marathon ever, and an analysis that could help explain why birds are the colours they are.Research Highlight: Physicists find a way to set a new marathon recordResearch Highlight: Which birds are drab and which dazzle?

But it’s unknown how much the trees can endure before their leaves start to die. A team has combined multiple data sources to try and answer this question, and suggest that a warming of 3.9 °C would lead to many leaves reaching a tipping point at which photosynthesis breaks down. This scenario would likely cause significant damage to these ecosystems’ role in vital carbon storage and as homes to significant biodiversity.Research article: Doughty et al.21:01 Briefing ChatThis time, a reexamination of Ötzi the iceman’s DNA suggests he had a different appearance, and the failure of a Russian mission to the moon.Nature News: Ötzi the Iceman has a new look: balding and dark-skinnedNature News: Russian Moon lander crash — what happened, and what’s next?Subscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.
