<p><strong>In this episode:</strong></p><h2></h2><h2>00:46 Optical clocks at sea</h2><p>Optical atomic clocks are the most precise timekeeping devices on the planet, but these devices are huge and difficult to work with, limiting their use outside of the lab. Now, researchers have developed a portable optical clock and demonstrated its robustness by sending it on a perilous sea journey. The team hope that this work will pave the way to more practical uses of optical clocks, such as on satellites where they could help improve the accuracy of GPS technologies.</p><p><em>Research Article: </em><a href="https://www.nature.com/articles/s41586-024-07225-2?utm_source=naturepod&utm_medium=podcast&utm_campaign=shownotes" rel="noopener noreferrer" target="_blank"><em>Roslund et al.</em></a></p><p>News and Views: <a href="https://www.nature.com/articles/d41586-024-01022-7?utm_source=naturepod&utm_medium=podcast&utm_campaign=shownotes" rel="noopener noreferrer" target="_blank">Robust optical clocks promise stable timing in a portable package</a></p><h2></h2><h2>09:34 Research Highlights</h2><p>Evidence of ritual burning of the remains of a Maya royal family, and the first solid detection of an astrophysical tau-neutrino.</p><p><em>Research Highlight: </em><a href="https://www.nature.com/articles/d41586-024-01075-8?utm_source=naturepod&utm_medium=podcast&utm_campaign=shownotes" rel="noopener noreferrer" target="_blank"><em>Burnt remains of Maya royalty mark a dramatic power shift</em></a></p><p><em>Research Highlight: </em><a href="https://www.nature.com/articles/d41586-024-01073-w?utm_source=naturepod&utm_medium=podcast&utm_campaign=shownotes" rel="noopener noreferrer" target="_blank"><em>Detectors deep in South Pole ice pin down elusive tau neutrino</em></a></p><h2></h2><h2>11:52 How marsupial gliding membranes evolved</h2><p>Several marsupial species have evolved a membrane called a patagium that allows them to glide gracefully from tree to tree. Experiments show that mutations in areas of DNA around the gene Emx2 were key to the evolution of this ability, which has appeared independently in multiple marsupial species.</p><p><em>Research article: </em><a href="https://www.nature.com/articles/s41586-024-07305-3?utm_source=naturepod&utm_medium=podcast&utm_campaign=shownotes" rel="noopener noreferrer" target="_blank"><em>Moreno et al.</em></a></p><p><em>News and Views: </em><a href="http://www.nature.com/articles/d41586-024-01021-8?utm_source=naturepod&utm_medium=podcast&utm_campaign=shownotes" rel="noopener noreferrer" target="_blank"><em>Marsupial genomes reveal how a skin membrane for gliding evolved</em></a></p><h2></h2><h2>19:22 Briefing Chat</h2><p>How overtraining AIs can help them discover novel solutions, and researchers manage to make one-atom thick sheets of ‘goldene’.</p><p><em>Quanta Magazine: </em><a href="https://www.quantamagazine.org/how-do-machines-grok-data-20240412/?utm_source=naturepod&utm_medium=podcast&utm_campaign=shownotes" rel="noopener noreferrer" target="_blank"><em>How Do Machines ‘Grok’ Data?</em></a></p><p><em>Nature news: </em><a href="https://www.nature.com/articles/d41586-024-01118-0" rel="noopener noreferrer" target="_blank"><em>Meet ‘goldene’: this gilded cousin of graphene is also one atom thick</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><p><a href="https://www.nature.com/briefing/ai-robotics" rel="noopener noreferrer" target="_blank"><strong><em>Subscribe to Nature Briefing: AI and robotics</em></strong></a></p><hr><p style='color:grey; font-size:0.75em;'> Hosted on Acast.
