How quantum friction explains water’s strange flows in carbon nanotubes, and the latest from the Nature Briefing.In this episode:00:53 A theory for water’s baffling behaviour in carbon nanotubesAt large scales, water flows faster through a wider pipe than a narrower one. However, in tiny carbon nanotubes flow-rate is flipped, with water moving faster through the narrowest channels. This week, researchers have come up with a new explanation for this phenomenon: quantum friction. If validated, it could allow material designers to fine-tune flows through tiny channels, which could be useful in processes such as water purification.Research Article: <a href="https://www.nature.com/articles/s41586-021-04284-7?utm_source=naturepod&utm_medium=podcast&utm_campaign=shownotes" rel="noopener noreferrer" target="_blank">Kavokine et al.</a>06:43 Research HighlightsCreating soap bubbles that last 200,000 times longer, and hippos’ habit of aggressively spraying dung when they hear a stranger.Research Highlight: <a href="https://www.nature.com/articles/d41586-022-00172-w?utm_source=naturepod&utm_medium=podcast&utm_campaign=shownotes" rel="noopener noreferrer" target="_blank">No bursting for these record-breaking bubbles</a>Research Highlight: <a href="https://www.nature.com/articles/d41586-022-00173-9?utm_source=naturepod&utm_medium=podcast&utm_campaign=shownotes" rel="noopener noreferrer" target="_blank">Hippos know strangers’ voices — and make a filthy reply</a>09:08 Briefing ChatWe discuss some highlights from the Nature Briefing.
