Forty years ago, the catastrophic explosion at Chernobyl sent plumes of radioactive waste into the atmosphere. Now, New Scientist has gained exclusive access to learn how vital work to decontaminate the site has been derailed by Russia’s full-scale invasion of Ukraine

New Scientist reporter Matthew Sparkes secured unrivalled access to Chernobyl's most crucial scientific sites, where researchers are fighting to protect the area and ensure it remains safe amid the constant threat of attack from Russia

The astronauts of the Artemis II mission around the moon have made it home safely to Earth, marking the end of a triumphant mission and the beginning of a longer road to stay on the moon

Some cats will suddenly refuse to touch brands of cat food that they have eaten for years. Changing the way the food smells might solve the problem

A handful of plankton fossils buried in a small chunk of rock show that the oceans were teeming with life before the Late Ordovician mass extinction, the second most severe on record

Working in secret for more than two years, a group of mathematicians has set out to resolve of the longest and most bitter battles in modern mathematics

Physicists have shown how time can effectively be reversed for some quantum systems, which would allow for new ways to harvest energy

The incompleteness theorem is accepted as part of the mathematical canon today, but columnist Jacob Aron says it was a bombshell when Kurt Gödel first introduced it. Gödel’s seminal work directly contradicted one of the great minds of mathematics and limited the field forever

Two extremely precise experiments agree with a previously shocking measurement of just how big the proton is, which may help future searches for new particles

Researchers who observed a murderous conflict unfolding in a once-unified group of wild chimpanzees say there are parallels with civil wars in human societies

A woman with three different autoimmune conditions had all of them treated simultaneously by genetically modifying her immune cells to kill off the rogue ones causing problems

Elizabeth Banks stars as an author shrunk by her scientist husband Matthew Macfadyen in this major new series – but it fails to live up to its promise, finds Josh Bell
