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 Samples retrieved from asteroid Ryugu indicate that it once had flowing water in far greater volumes than previously …

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 because we travel more than our ancestors did Most human populations evolved to cope with low or high local levels of micronutrients such as zinc, but these localised adaptations might …
We evolved to match local micronutrient levels, which may be a problem Read More »
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 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 …

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 A rock found last year on …
NASA hasn’t found life on Mars yet – but signs are promising Read More »
Scientists uncovered a 310-million-year-old fish fossil with a “tongue bite,” teeth on the roof and floor of its mouth that worked like a second jaw. This adaptation, previously thought to have appeared much later, shows how fish rapidly experimented with new feeding strategies after mass extinction. Scientists uncovered a 310-million-year-old fish fossil with a “tongue …

A small tissue fold in fly embryos, once thought purposeless, plays a vital role in stabilizing tissues. Researchers show that it absorbs stress during early development, and its position and timing likely shaped its evolutionary emergence.

Scientists at the University of Bath have developed a simple three-minute brainwave test called Fastball EEG that can detect memory problems years before Alzheimer’s is typically diagnosed. Unlike traditional memory tests, it passively records brain responses to images and has now been proven effective in people’s homes. With breakthrough Alzheimer’s drugs working best in early …

It has long been claimed that only one mammal – the golden mole – has fur that shimmers with rainbow colours, but it now turns out that at least a dozen more mammals have iridescent fur too It has long been claimed that only one mammal – the golden mole – has fur that shimmers …

Thousands of women are using GLP-1 drugs like Ozempic for weight loss without contraception, leading to unintended pregnancies and potential risks for unborn babies. Experts warn clearer medical guidance is urgently needed.
