Most human populations evolved to cope with low or high local levels of micronutrients such as zinc, but these localised adaptations might now be problematic

An exceptionally loud collision between two black holes has been detected by the LIGO gravitational wave observatory, enabling physicists to test a theorem postulated by Stephen Hawking in 1971

A rock found last year on the surface of Mars offered tantalising evidence that life once existed on the Red Planet. Now scientists have found yet more evidence that could point to the existence of ancient organisms – but we can't know for certain without returning samples to Earth

For women going through perimenopause, there is no shortage of advice on how to deal with the symptoms – but which strategies show real results, and which are social media hype?

A part of the brain that is about the size of a sunflower seed in people could play a big role in our food consumption

Samples retrieved from asteroid Ryugu indicate that it once had flowing water in far greater volumes than previously thought possible, suggesting that similar objects may have played a role in delivering vast quantities of water to Earth

The public can submit names to travel along with four astronauts on an orbital journey to the moon next year

Depending on where you smack a planet-threatening asteroid, it might ricochet back to Earth.

The Perseverance rover’s new findings set the stage for bringing Martian samples back to Earth to test whether microbes once inhabited the Red Planet

Spacetime ripples from a black hole collision across the cosmos have confirmed weird aspects of black hole physics

"GW250114 is the loudest gravitational wave event we have detected to date; it was like a whisper becoming a shout."

"There is no evidence of microbes on Mars today, but if any had been present on ancient Mars, they too might have reduced sulfate minerals to form sulfides in such a lake at Jezero crater."

The "Tranche 1 Transport Layer" network will eventually consists of 126 satellites in low Earth orbit.

Chile is a hotspot for telescopes peering up into deep space to study structures like stars, black holes, dark matter and galaxies.
