00:49 Separating heavy water with molecular cagesHeavy water is molecule very similar to H2O but with deuterium isotopes in the place of hydrogen atoms. Heavy water is useful in nuclear reactions, drug design and nutritional studies, but it's difficult to separate from normal water because they have such similar properties. Now, a team have developed a new separation method using tiny molecular cages, which they hope opens up more energy efficient ways to produce heavy water.Research article: Su et al.News and Views: A molecular flip-flop for separating heavy water07:23 Research HighlightsHow dancers can feel the beat even when they can’t hear it, and how climate change might move desert dunes.Research Highlight: Dancers pick up the pace on a bass beat — even though it’s inaudibleResearch Highlight: Desert dunes pose more danger as Earth warms09:25 Monitoring bridge health using crowd dataBridges are vital pieces of infrastructure but their structural health is hard to monitor, requiring either sophisticated
