AI unlocks Atlantic circulation insights from 20 years of ocean float data
For more than 20 years, about 4,000 autonomous profiling floats have been drifting through the ocean. They form part of the international Argo program (Argo—global array of profiling floats). At regular intervals, they descend to a depth of 2,000 meters (6,600 feet) and, as they
A new 'golden age' of mathematics may be dawning, thanks to AI and human ingenuity
In May 2026, OpenAI released a new math result that sent shock waves throughout the world of mathematical research. A major unsolved problem called the "unit distance conjecture" had just been resolved by generative AI.
Alan Turing's gay short story reveals 'fun, cheeky' man who loved sex and literature
A startling new study of a little-known, unpublished short story by Alan Turing challenges our understanding of the man who played a key role in cracking the Nazis' Enigma code, developed the theoretical underpinnings of the first computers and laid the groundwork for the develop
