<p><strong>In this episode:</strong></p><h2></h2><h2>00:48 How mysterious skyrmions could power next-generation computers</h2><p>Skyrmions are tiny whirlpools of magnetic spin that some researchers believe have useful properties that could unlock new kinds of computing. However getting skyrmions to perform useful computational tasks has been tricky. Now researchers have developed a method to create and manipulate skyrmions in a way that is compatible with existing computing technology, allowing them to read and write data at a fraction of the energy cost of conventional systems. The team think this shows that skyrmions could be a viable part of the next generation of computers.</p><p><em>Research Article: </em><a href="https://www.nature.com/articles/s41586-024-07131-7?utm_source=naturepod&utm_medium=podcast&utm_campaign=shownotes" rel="noopener noreferrer" target="_blank"><em>Chen et al.</em></a></p><p>News and Views: <a href="https://www.nature.com/articlesd41586-024-00576-w" rel="noopener noreferrer" target="_blank">Magnetic whirlpools offer improved data storage</a></p><h2></h2><h2>07:51 Research Highlights</h2><p>How robotically-enhanced, live jellyfish could make ocean monitoring cheap and easy, and how collective saliva tests could be a cost-effective way of testing for a serious infant infection.</p><p><em>Research Highlight: </em><a href="https://www.nature.com/articles/d41586-024-00731-3" rel="noopener noreferrer" target="_blank"><em>These cyborg jellyfish could monitor the changing seas</em></a></p><p><em>Research Highlight: </em><a href="https://www.nature.com/articles/d41586-024-00733-1" rel="noopener noreferrer" target="_blank"><em>Pooling babies’ saliva helps catch grave infection in newborns</em></a></p><h2></h2><h2>10:01 AI identifies X factor hidden within Zebra finch songs</h2><p>Male songbirds often develop elaborate songs to demonstrate their fitness, but many birds only learn a single song and stick with it their entire lives. How female birds judge the fitness between these males has been a long-standing puzzle. Now, using an AI-based system a team has analysed the songs of male zebra finches and shown that some songs have a hidden factor that is imperceptible to humans. Although it’s not clear exactly what this factor is, songs containing it were shown to be harder to learn and more attractive to females. The researchers hope that this AI-based method will allow them to better understand what makes some birdsong more attractive than others.</p><p><em>Research article: </em><a href="https://www.nature.com/articles/s41586-024-07207-4" rel="noopener noreferrer" target="_blank"><em>Alam et al. </em></a></p><p><em>News and Views: </em><a href="https://www.nature.com/articles/d41586-024-00677-6" rel="noopener noreferrer" target="_blank"><em>Birds convey complex signals in simple songs</em></a></p><h2></h2><h2>20:04 Briefing Chat</h2><p>How H5N1 avian influenza is threatening penguins on Antarctica, and why farmed snake-meat could be a more environmentally-friendly way to produce protein for food.</p><p><em>Nature News:</em><a href="https://www.nature.com/articles/d41586-024-00807-0" rel="noopener noreferrer" target="_blank"><em> Bird-flu threat disrupts Antarctic penguin studies</em></a></p><p><em>Scientific American: </em><a href="https://www.scientificamerican.com/article/snake-steak-could-be-a-climate-friendly-source-of-protein" rel="noopener noreferrer" target="_blank"><em>Snake Steak Could Be a Climate-Friendly Source of Protein</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.
