Mice seemed to reap some of the benefits of sleep by having their brain activity stimulated while they were awake, and the researchers plan to test the approach on people

A team in the US has reported promising results after using an improved form of CRISPR to gene-edit human embryos, but a major issue remains unsolved

Scientists warn that the Trump administration's push to dismantle a vital network of ocean-sensing instruments will stymie crucial weather and climate monitoring in the Pacific and Atlantic

The modern world depends on open-source software maintained by volunteers, but the added demands of checking and fixing AI-written submissions are causing some to burn out and quit

Mice that contain cells with an added rat chromosome have been created by scientists. The next step is to try this with frozen elephant tissue – and if that works, the team will try it with frozen mammoths

A seemingly simple set of rules kicks off a kind of mathematical magic trick, which has kept great minds busy since the 1930s. Columnist Jacob Aron explores the origins of the Collatz conjecture, why it is so addictive to mathematicians and whether AI could help us solve it once and for all

Parents report loving their partners less within the first year of having a child, but that doesn't mean the feeling is permanent or inevitable
