In this episode:<h2>01:28 Inflammation’s role in memory</h2>How memories are stored is an ongoing question in neuroscience. Now researchers have found an inflammatory pathway that responds to DNA damage in neurons has a key role in the persistence of memories. How this pathway helps memories persist is unclear, but the researchers suggest that how the DNA damage is repaired may play a role. As inflammation in the brain is often associated with disease, the team were surprised by this finding, which they hope will help uncover ways to better preserve our memories, especially in the face of neurodegenerative disorders.Research Article: <a href="https://www.nature.com/articles/s41586-024-07220-7" rel="noopener noreferrer" target="_blank">Jovasevic et al.</a>News and Views: <a href="https://www.nature.com/articles/d41586-024-00679-4" rel="noopener noreferrer" target="_blank">Innate immunity in neurons makes memories persist</a><h2></h2><h2>08:40 Research Highlights</h2>The effect of wind turbines on property values, and how waste wood can be used to 3D print new wooden objects.Research Highlight:<a href="https://www.nature.com/articles/d41586-024-00766-6" rel="noopener noreferrer" target="_blank"> A view of wind turbines drives down home values — but only briefly</a>Research Highlight: <a href="https://www.nature.com/articles/d41586-024-00767-5" rel="noopener noreferrer" target="_blank">Squeeze, freeze, bake: how to make 3D-printed wood that mimics the real thing</a><h2></h2><h2>11:14 How melting ice is affecting global timekeeping</h2>Due to variations in the speed of Earth’s rotation, the length of a day is rarely exactly 24 hours. By calculating the strength of the different factors affecting this, a researcher has shown that while Earth’s rotation is overall speeding up, this effect is being tempered by the melting of the polar ice caps. As global time kept by atomic clocks occasionally has to be altered to match Earth’s rotation, human-induced climate change may delay plans to add a negative leap-second to ensure the two align.Research article: <a href="https://www.nature.com/articles/s41586-024-07170-0" rel="noopener noreferrer" target="_blank">Agnew</a>News and Views: <a href="https://www.nature.com/articles/d41586-024-00850-x" rel="noopener noreferrer" target="_blank">Melting ice solves leap-second problem — for now</a><h2></h2><h2>20:04 Briefing Chat</h2>An AI for antibody development, and the plans for the upcoming Simons observatory.Nature News:<a href="https://www.nature.com/articles/d41586-024-00846-7" rel="noopener noreferrer" target="_blank"> ‘A landmark moment’: scientists use AI to design antibodies from scratch</a>Nature News: <a href="https://www.nature.com/articles/d41586-024-00333-z" rel="noopener noreferrer" target="_blank">‘Best view ever’: observatory will map Big Bang’s afterglow in new detail</a><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">Subscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.</a><a href="https://www.nature.com/briefing/ai-robotics" rel="noopener noreferrer" target="_blank">Subscribe to Nature Briefing: AI and robotics</a><hr> Hosted on Acast.
