Bleaching has devastated reefs around the world, raising fears of an irreversible shift. Yet new interventions have revealed that corals can be remarkably resilient if we can give them enough help to recover

NASA’s Artemis III crew includes three NASA astronauts and one European Space Agency astronaut

To run errands across apps, Apple’s upgraded assistant needs deep access to personal data that the company has walled off for years

Meteorites are (usually) gifts from the heavens. They provide unique insights to parts of the solar system that we couldn’t access otherwise - either because it's too expensive, or because the solar system itself has evolved since it was formed. A new paper from researchers at the University of Colorado Boulder details how one particularly famous meteorite offers a window into just such a bygone age of the solar system - and the failed planet that was a part of it.

Neptune is definitely the odd one out of the gas giants. It’s tilted at a strange angle, and its moons are completely different from any other gas giant we know of. A new paper, published in Science Advances from researchers at CalTech, posits that might be because Triton, by far Neptune’s largest moon, absolutely obliterated the regular moon system it previously had, except for one particular exception - Nereid.

Weight lifting and other forms of resistance training can increase bone density, lower diabetes risk and boost mental health

The satellites being launched by Amazon are brighter than IAU-recommended limits — which means they'll interfere with astronomy.

Hints of high-pressure chemistry within a rare meteorite suggest this fallen space rock comes from a planet gone wrong in the solar system’s early history

The Proba-3 mission’s Coronagraph spacecraft and its main scientific instrument, ASPIICS, are both at full health, ready to resume routine formation flying operations and deliver more breathtaking artificial eclipses.

The best blood test for herpes is only available at a single lab. What would it take for that to change?

These eye-catching insects offer a prime opportunity for scientists to dig deep into invasion ecology and evolutionary biology

Drill cores at the impact site of the Chicxulub asteroid show evidence that, alongside widespread destruction, the collision created a vast underground ecosystem filled with hot water that sheltered microbial life

Brown dwarfs are somewhere between the size of a planet and a star, so how could we have potentially mistaken two of them for distant galaxies? Columnist Chanda Prescod-Weinstein argues that solving this cosmic mix-up is particularly possible now, as galaxy research has never been stronger

When asteroids slam into Earth, they can create hydrothermal vent systems

Physics is considered a cold, hard science – but it will transform your life if you view it with a bit more subjectivity, says Karmela Padavic-Callaghan

For decades, economic growth and fossil-fuel consumption have been tightly intertwined. As cities have expanded, rising prosperity has often been accompanied by worsening air pollution. New research, however, suggests that this relationship is changing – and satellite data are helping to prove it.
