Graphene’s magic angle reveals a new twist

Probing the superconducting properties of graphene and bacteria that can use manganese to grow.

01:15 Magic angle graphene

If you sandwich two sheets of graphene together and twist one in just the right way, it can gain some superconducting properties. Now, physicists have added another material to this sandwich which stabilises that superconductivity, a result that may complicate physicists’ understanding of magic angles. Research Article: Arora et al.

08:22 Coronapod

With evidence mounting that SARS-CoV2 can spread in tiny aersolised droplets, researchers have called on the WHO to change their guidance for disease prevention. News: Mounting evidence suggests coronavirus is airborne — but health advice has not caught up; Research article: Morwaska et al.; WHO: Transmission of SARS-CoV-2: implications for infection prevention precautions

Repairing human lungs by hooking them up to pigs, and a new form of carbon. Research Highlight: How to use a live pig to revitalize a human lung; Research Highlight: This material is almost as hard as diamond — but as light as graphite

21:46 Manganese munchers

For decades it’s been thought that microbes that use manganese as an energy source must exist. Now, for the first time, researchers have found evidence that they do. Research Article: Yu and Leadbetter

29:12 Briefing Chat

We take a look at some highlights from the Nature Briefing. This time we discuss DNA evidence of contact between ancient Native Americans and Polynesians, reintroduction of bison to the UK, and the first extinction of a modern marine fish. Nature News: Ancient voyage carried Native Americans’ DNA to remote Pacific islands; The Guardian: Wild bison to return to UK for first time in 6,000 years; Scientific American:
