What the atomic structure of enamel tells us about tooth decay

On this week’s podcast, how the molecular structure of tooth enamel may impact decay, and a mysterious planetary core from a half-formed gas giant.


In this episode:


00:46 Unravelling tooth enamel

Researchers have been looking into the structure and composition of enamel in an effort to better understand tooth decay. Research Article: DeRocher et al.


07:02 Research Highlights

An adhesive patch to help heal heart-attacks, and a new technique to inspect the structure of 2D ‘wonder materials’. Research Highlight: A healing patch holds tight to a beating heart; Research Highlight: A snapshot shows off super-material only two atoms thick


09:21 Unusual planet

In the region close to stars known as the ‘hot Neptune desert’ planets of Neptune’s size are rarely found, but this week scientists have uncovered one and are trying to untangle its mysteries. Research Article: Armstrong et al.


14:52 Briefing Chat

We take a look at some highlights from the Nature Briefing. This time we talk about the pitfalls of using CRISPR in human embryos, and renaming of moon craters inadvertently named after Nazi scientists. Nature News: CRISPR gene editing in human embryos wreaks chromosomal mayhem; Prospect Magazine: Astronomers unknowingly dedicated moon craters to Nazis. Will the next historical reckoning be at cosmic level?
