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 Hi
