00:47 How a racing heart could trigger anxietyAnxiety can make the heart beat faster, but could the reverse be true as well? That question has been much debated, but hard to test.

They hope that this knowledge could help to improve therapies for treating anxiety-related conditions in the future.Research article: Hsueh et al.News & Views: How an anxious heart talks to the brain08:32 Research HighlightsThe chance discovery of the smallest rock seen so far in the Solar System, and the first brain recording from a freely swimming octopus.Research Highlight: Asteroid photobombs JWST practice shotsResearch Highlight: How to measure the brain of an octopus10:57 How NASA’s DART mission beat expectiationsIn September 2022, NASA’s DART spacecraft smashed into a space rock known as Dimorphos, which orbits a near-Earth aster
