00:46 How hot can solid gold get?A new study suggests that gold can be superheated far beyond its melting point without it becoming a liquid. Using an intense burst from a laser, a team heated a gold foil to 14 times its melting point, far beyond a theoretical limit put forward in previous studies. The team suggest that the speed at which they heated the gold allowed them to shoot past this limit, but there is scepticism about whether the team actually achieved the level of heating they report.Research Article: White et al.News and Views: Solid gold superheated to 14 times its melting temperatureNews: Superheated gold stays solid well past its predicted melting point10:05 Research HighlightsHow island life led to huge wingspans for flying foxes, and how a sugary diet ‘rewires’ a mouse’s brain.Research Highlight: How the world’s biggest bats got their enormous wingspansResearch Highlight: How sugar overload in early life affects the brain later12:30 Researchers warn about the threat of
