A new study has found that the stride length of a dog’s front legs can be used to accurately diagnose their cognitive decline. Because a person’s change in gait can play a significant role in spotting early signs of Alzheimer's disease or dementia.

When our team first reported these rocks in 2025, we suggested they were part of an ancient impact crater at the ironically named North Pole Dome. But one question remained difficult: exactly how old was the impact?

Light could put the brakes on material diffusing through a solution, and the reason why touches on some of the stranger corners of quantum mechanics.

It’s not often that we get guests. So when the interstellar intruder 3I/ATLAS came zooming through our Solar System last year, it provided astronomers with a perfect opportunity to study a rock from another part of the galaxy.

New research on a pterosaur fossil reveals secrets of the creature’s life, including microscopic inner structures of its bones and traces of its biology and diet. The findings show that molecular evidence can survive for more than 100 million years.

An experiment conducted by a team of researchers from Texas A&M University has revealed a healing sequence in mammalian physiology that rebuilds lost skeletal structure, albeit with less than perfect results.

In simulations, Boston University researcher Brian Walsh and colleagues found that their system, dubbed StormWall, could halve the intensity of a geomagnetic storm.

The volatile seismic zone along the roughly 750-mile San Andreas Fault beneath California are "critically stressed" – a level of pressure that has reached its highest point in 1,000 years – increasing the likelihood of a big earthquake hitting the US.

Three years on from deploying ground-penetrating radar to "spy" on one of Australia's most endangered and elusive species, scientists have learnt just how adaptable the animals are. And there's also some good news for rebuilding the population.
