In this episode:
The James Webb Space Telescope (JWST) is revealing the makeup of brown dwarfs — strange space objects that blur the line between a planet and a star. And it appears that methane in the atmosphere of one of these objects, named W1935, is emitting infrared radiation. Where the energy comes from is a mystery however, researchers hypothesise that the glow could be caused by an aurora in the object’s atmosphere, perhaps driven by an as-yet unseen moon.

The discovery that bitter taste receptors may date back 450 million years, and the first planet outside the Solar System to boast a rainbow-like phenomenon called a ‘glory’.
Research Highlight: Bitter taste receptors are even older than scientists thought

Working memory is a fundamental process that allows us to temporarily store important information, such as the name of a person we’ve just met. However distractions can easily interrupt this process, leading to these memories vanishing. By looking at the brain activity of people doing working-memory tasks, a team have now confirmed that working memory requires two brain regions: one to hold a memory as long as you focus on it; and another to control its maintenance by helping you to not get distracted.
