Here is how to understand OpenAI’s major mathematical breakthrough
Since OpenAI announced its solution to one of the prestigious Millennium Prize Problems, mathematicians have been urgently trying to unpick what it means
The world’s biggest carbon sink may start emitting CO2 after net zero
If the carbon dioxide in the atmosphere declines, the Southern Ocean is likely to begin emitting more carbon than it absorbs, prolonging global warming
What’s next for mathematics now that AI is upending the field?
Famous and challenging problems in mathematics are falling to AI at a rapid pace. Where does this leave mathematicians, and what will the field look like in coming years?
Cracking the ageing code
Where financial health meets human longevity.
August was the joint hottest month on record
Global warming and a record El Niño have pushed Earth’s temperature more than 1.5°C above the pre-industrial average, and further heat is on the way
Why our common ancestor with chimpanzees keeps getting further away
The more we learn about chimpanzees, the more they resemble us – but the further back in time our shared ancestor seems to be. Columnist Michael Marshall explores how both can be true
