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 universe

Supermassive 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.

13:35 A clinical trial of an AI heart assessor

A team of researchers and clinicians report results of a clinical trial designed to test the ability of an AI to accurately interpret echocardiogram images – a technique frequently used to assess heart health. 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.
