Living on Mars would probably suck — here's why

<description>&lt;p&gt;&lt;strong&gt;In this episode:&lt;/strong&gt;&lt;/p&gt;&lt;p&gt;&lt;br&gt;&lt;/p&gt;&lt;h2&gt;00:46 Mysterious methane emission from a cool brown dwarf&lt;/h2&gt;&lt;p&gt;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.&lt;/p&gt;&lt;br&gt;&lt;p&gt;&lt;em&gt;Research Article: &lt;/em&gt;&lt;a href="https://www.nature.com/articles/s41586-024-07190-w?utm_source=naturepod&amp;amp;utm_medium=podcast&amp;amp;utm_campaign=shownotes" rel="noopener noreferrer" target="_blank"&gt;&lt;em&gt;Faherty et al.&lt;/em&gt;&lt;/a&gt;&lt;/p&gt;&lt;p&gt;&lt;br&gt;&lt;/p&gt;&lt;h2&gt;10:44 Research Highlights&lt;/h2&gt;&lt;p&gt;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’.&lt;/p&gt;&lt;br&gt;&lt;p&gt;&lt;em&gt;Research Highlight: &lt;/em&gt;&lt;a href="https://www.nature.com/articles/d41586-024-01031-6?utm_source=naturepod&amp;amp;utm_medium=podcast&amp;amp;utm_campaign=shownotes" rel="noopener noreferrer" target="_blank"&gt;&lt;em&gt;Bitter taste receptors are even older than scientists thought&lt;/em&gt;&lt;/a&gt;&lt;/p&gt;&lt;p&gt;&lt;em&gt;Research Highlight: &lt;/em&gt;&lt;a href="https://www.nature.com/articles/d41586-024-01032-5?utm_source=naturepod&amp;amp;utm_medium=podcast&amp;amp;utm_campaign=shownotes" rel="noopener noreferrer" target="_blank"&gt;&lt;em&gt;An exoplanet is wrapped in glory&lt;/em&gt;&lt;/a&gt;&lt;/p&gt;&lt;p&gt;&lt;br&gt;&lt;/p&gt;&lt;h2&gt;13:07 How working memory works&lt;/h2&gt;&lt;p&gt;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.

Brain areas work in tandem to temporarily store important information, and an aurora on a cool brown dwarf.

In this episode: <h2>00:46 Mysterious methane emission from a cool brown dwarf</h2>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.
