Superconductivity gets heated

A high pressure experiment reveals the world’s first room-temperature superconductor, and a method to target ecosystem restoration.

In this episode:

00:44 Room-temperature superconductivity

For decades, scientists have been searching for a material that superconducts at room temperature. This week, researchers show a material that appears to do so, but only under pressures close to those at the centre of the planet.

A new method provides 3D printed materials with some flexibility, and why an honest post to Facebook may do you some good. Research Highlight: A promising 3D-printing method gets flexible; Research Highlight: Why Facebook users might want to show their true colours

22:11 The best way to restore ecosystems

Restoring degraded or human-utilised landscapes could help fight climate change and protect biodiversity. However, there are multiple costs and benefits that need to be balanced. Researchers hope a newly developed algorithm will help harmonise these factors and show the best locations to target restoration.
