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 superconductivityFor 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.

And how much evidence is enough to turn the tide on this ongoing debate?

Research Highlight: A promising 3D-printing method gets flexible; Research Highlight: Why Facebook users might want to show their true colours22:11 The best way to restore ecosystemsRestoring 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.
