Episode notes

There is a sort of d and a that uses a different system to the one you learnt at school. This kind of non a, t, c, g, d and a maybe protects these pages from some of the mechanisms that bacteria use to break them down. So there's talk about, maybe this could be used to make more stable d an a molecules. It might make d and a fold differently, which could be used in d and a origami,. Which has been used for a variety of different things.

A new neural interface lets people type with their mind, and a crafting journey into materials science.

In this episode:

00:45 A brain interface to type out thoughts

Researchers have developed a brain-computer interface that is able to read brain signals from people thinking about handwriting, and translate them into on-screen text. The team hope this technology could be used to help people with paralysis to communicate quicker than before.

07:37 Research Highlights

Light-sensitive cells help headless worms ‘see’ with their bodies, and a wearable device that monitors itchiness.

10:26 The science of everyday materials

Materials scientist Anna Ploszajski joins us to talk about her new book Handmade, which details how her journey into craft helped shape her materials research.

18:26 Briefing Chat

We discuss some highlights from the Nature Briefing. This time, the genomes of some viruses that contain a very unusual DNA nucleobase, and the smouldering nuclear reactions that remain in the wreckage of the Chernobyl Nuclear Power Plant.

Science: ‘It’s like the embers in a barbecue pit.’ Nuclear reactions are smoldering again at Chernobyl
