<h2>00:47 A metadevice for faster electronics</h2>In the past, increasing the speeds of electronics required designing smaller components, but further reductions in size are being hampered by increasing resistance. To get around this, researchers have demonstrated a ‘metadevice’, which prevents resistance building up by concentrating the flow of signals into specific regions of the device. The hope is that this meta-method could be used to create even smaller electrical components in the future.Research article: <a href="https://www.nature.com/articles/s41586-022-05595-z" rel="noopener noreferrer" target="_blank">Nikoo & Matioli</a><h2>06:27 Research Highlights</h2>How waiting times for services are higher for people in the US with low incomes, and how your brain hears an alarm while you’re asleep.Research Highlight: <a href="https://www.nature.com/articles/d41586-023-00372-y" rel="noopener noreferrer" target="_blank">Who wastes more time waiting?

There is much concern that these trends are linked, but hard evidence has been hard to come by. So how can scientists get a better understanding of what’s going on? In a Comment article for Nature, researchers argue that, rather than lumping ‘young people’ into one homogeneous group, future studies should consider where they are in terms of their development, as this could influence the potential impacts of social media use.Comment: <a href="https://www.nature.com/articles/d41586-023-00402-9" rel="noopener noreferrer" target="_blank">How social media affects teen mental health: a missing link</a><h2>19:52 Briefing Chat</h2>We discuss some highlights from the Nature Briefing.
