<p><strong>In this episode:</strong></p><h2>00:45 A bright satellite is concerning researchers</h2><p>Satellites reflect sunlight down to Earth, and some do so with such intensity it risks obscuring astronomers' observations from ground-based telescopes. A paper in Nature suggests that the telecommunications satellite called BlueWalker 3 at times outshines most stars visible from Earth. Astronomers worry about the increasing number of such bright satellites making astronomy more difficult, and so the team suggest that future launches should undergo impact assessments.</p><p><em>Research article: </em><a href="https://www.nature.com/articles/s41586-023-06672-7?utm_source=naturepod&utm_medium=podcast&utm_campaign=shownotes" rel="noopener noreferrer" target="_blank"><em>Nandakumar et al.</em></a></p><p><em>Nature News: </em><a href="https://www.nature.com/articles/d41586-023-03054-x?utm_source=naturepod&utm_medium=podcast&utm_campaign=shownotes" rel="noopener noreferrer" target="_blank"><em>Huge new satellite outshines nearly every star in the sky</em></a></p><h2></h2><h2>09:27 Research Highlights</h2><p>Analysis of carrot genomes reveals how the vegetable got its orange hue, and the self-healing diamond that can fix microscopic fractures.</p><p><em>Research article: </em><a href="https://www.nature.com/articles/s41477-023-01526-6?utm_source=naturepod&utm_medium=podcast&utm_campaign=shownotes" rel="noopener noreferrer" target="_blank"><em>Coe et al.</em></a></p><p><em>Research Highlight: </em><a href="https://www.nature.com/articles/d41586-023-03011-8?utm_source=naturepod&utm_medium=podcast&utm_campaign=shownotes" rel="noopener noreferrer" target="_blank"><em>Crack this kind of diamond, and it heals itself</em></a></p><h2></h2><h2>11:47 The last meal of a 400-million-year-old trilobite</h2><p>Trilobites are a group of extinct marine arthropods distantly related to animals like crabs and spiders. Although found throughout the fossil record, little is known about the lives of this diverse group of animals. Now, a team has used powerful x-rays to peer inside a trilobite fossil and uncovered the contents of its last meal, over 400-million-years ago. This animal appears to have been an unfussy scavenger, gorging itself on a variety of small, shelled animals.</p><p><em>Research article:</em><a href="https://www.nature.com/articles/s41586-023-06567-7?utm_source=naturepod&utm_medium=podcast&utm_campaign=shownotes" rel="noopener noreferrer" target="_blank"><em> Kraft et al.</em></a></p><h2></h2><h2>22:20 Nobel News</h2><p>Flora Graham from the Nature Briefing joins us to talk about the winners of this year’s science Nobel Prizes.</p><p><em>Nature News: </em><a href="https://www.nature.com/articles/d41586-023-03046-x?utm_source=naturepod&utm_medium=podcast&utm_campaign=shownotes" rel="noopener noreferrer" target="_blank"><em>Pioneers of mRNA COVID vaccines win medicine Nobel</em></a></p><p><em>Nature News: </em><a href="https://www.nature.com/articles/d41586-023-03047-w?utm_source=naturepod&utm_medium=podcast&utm_campaign=shownotes" rel="noopener noreferrer" target="_blank"><em>Physicists who built ultrafast ‘attosecond’ lasers win Nobel Prize</em></a></p><p><em>Nature News: </em><a href="https://www.nature.com/articles/d41586-023-03048-9" rel="noopener noreferrer" target="_blank"><em>Tiny ‘quantum dot’ particles win chemistry Nobel</em></a></p><p><a href="https://www.nature.com/briefing/signup/?utm_source=podcast-organic&utm_medium=podcast&utm_campaign=briefing-signup&utm_content=shownotes" rel="noopener noreferrer" target="_blank"><strong><em>Subscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.</em></strong></a></p><hr><p style='color:grey; font-size:0.75em;'> Hosted on Acast.
