In this episode:01:28 Inflammation’s role in memoryHow 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: Jovasevic et al.News and Views: Innate immunity in neurons makes memories persist08:40 Research HighlightsThe effect of wind turbines on property values, and how waste wood can be used to 3D print new wooden objects.Research Highlight: A view of wind turbines drives down home values — but only brieflyResearch Highlight: Squeeze, freeze, bake: how to make 3D-printed wood that mimics the real thing11:14 How melting ice is affecting global timekeepingDue 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: AgnewNews and Views: Melting ice solves leap-second problem — for now20:04 Briefing ChatAn AI for antibody development, and the plans for the upcoming Simons observatory.Nature News: ‘A landmark moment’: scientists use AI to design antibodies from scratchNature News: ‘Best view ever’: observatory will map Big Bang’s afterglow in new detailSubscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.Subscribe to Nature Briefing: AI and robotics Hosted on Acast.
