Giant black-hole pair from the early Universe gives clues to how galaxies form

00:46 A pair of supermassive black holes in the distant universeSupermassive black holes are found at the centre of galaxies across the universe. But observations of galaxies with more than one – caused by the merging of two galaxies – have been rare. Now, researchers have combined data from a number of telescopes and satellites, to reveal a pair of supermassive blackholes farther from Earth than any pair detected previously. They hope this will offer insights into how galaxies form.Research article: Chen et al.News and Views: Distant supermassive black holes spotted in galaxy merger10:53 Research HighlightsWhy appetite can increase after dieting, and gliding mammals’ flight-associated genes.Research Highlight: Can’t keep off lost weight?

The results showed that the AI was as good at measuring a metric of cardiac function as a trained human, but was able to speed up the diagnosing process, suggesting this method could play a role in improving healthcare in future.Research article: He et al.20:42 Briefing ChatWe discuss some highlights from the Nature Briefing.
