Super-efficient catalyst boosts hopes for hydrogen fuel

This week, perfecting catalysts that split water using light, and the mystery of missing matter in the Universe.In this episode:00:44 Water splittingAfter decades of research scientists have managed to achieve near perfect efficiency using a light-activated catalyst to separate hydrogen from water for fuel. Research Article: Takata et al.; News and Views: An almost perfectly efficient light-activated catalyst for producing hydrogen from water05:37 Research HighlightsThe hidden water inside the earth’s core, and how working memory ‘works’ in children. Research Highlight: Our planet’s heart is watery; Research Highlight: A child’s memory prowess is revealed by brain patterns07:53 Measuring matterEstimations of baryonic matter in the Universe have conflicted with observations, but now researchers have reconciled these differences. Research Article: Macquart et al.13:42 Pick of the BriefingWe pick our highlights from the Nature Briefing, including the possibility of a black hole in our solar system, and the biting bees that force plants to bloom. Physics World: If ‘Planet Nine’ is a primordial black hole, could we detect it with a fleet of tiny spacecraft?; Scientific American: Bumblebees Bite Plants to Force Them to Flower (Seriously)Subscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.
