This week, the spaceborne lab that allows investigation of quantum states, and the debate surrounding how mountain height is maintained.

In this episode:

01:18 Space lab

Scientists have built a lab on the international space station, allowing them to remotely investigate quantum phenomena in microgravity. Research Article: Aveline et al.; News and Views: Quantum matter orbits Earth

08:37 Research Highlights

Trackable ‘barcode’ bacteria, and physicists simulate near light speed cycling. Research Highlight: ‘Barcode’ microbes could help to trace goods — from lettuce to loafers; Research Highlight: What Einstein’s theory means for a cyclist moving at almost light speed

10:48 Maintaining mountain height

For a long time many researchers have thought that mainly erosion controls the height of mountains, but new research suggests that tectonic forces play a bigger role. Research Article: Dielforder et al.; News and Views: Mountain height might be controlled by tectonic force, rather than erosion

16:12 Pick of the Briefing

We pick our highlights from the Nature Briefing, including how sleep deprivation kills, and a monumental Maya structure hidden in plain sight. Quanta Magazine: Why Sleep Deprivation Kills; National…
