Geoscientists have used earthquakes to study the composition of the lower portion of the Earth’s mantle under the Pacific Ocean – and they’ve discovered something quite peculiar.

Along the coasts of Chile and Peru you may find a “living rock” that looks like it bleeds. Known to science as Pyura chilensis, it’s a filter feeder related to sea squirts, but you might not know that for looking at it. At a push you might say it looked like a sea urchin, but […]

Comet C/2024 G3 (ATLAS) is expected to become brighter than Venus next week, and will probably be the brightest comet of 2025. It has already achieved a brightness similar to famously bright stars like Antares and Spica – however, that doesn’t mean it’s easy to see, nor will it become so.  Advertisement Whereas Venus is […]

It’s the “Bleak Midwinter” in the Northern Hemisphere – so, in case you’ve been living under a well-insulated rock, cold weather and snowfalls are hardly unexpected in many parts of the world.

When you die on Earth, you generally know what will happen to your body, even if you’d rather not. But what happens to it if you die in space, on the Moon, or on the way to the Moon? Advertisement Though it’s not something NASA likely wants to think about, the space agency does have […]

In the animal kingdom, it is often the case that males are bigger, louder, and more visually impressive to look at. All this posturing shows off how fit they are to a prospective mate and might lead to better chances of breeding. However, in the world of the dusky pipefish, it is actually the smaller […]

We modern humans love a long hot soak but linger too long and something a bit gross happens: the skin on your hands wrinkles up making them look like fleshy prunes. It’s often assumed that we’re just absorbing water, but skin is waterproof and – actually – not everybody gets pruny in the bath. So, […]

Have you ever wondered how it is that plants avoid pollinating themselves? Walnut trees have evolved to avoid this by separating their male and female flowers in time, with the flowers of one sex blooming first, and the other coming second. Advertisement Walnut trees can differ in whether they lead with female flowers or male […]

The Magyars – or Hungarians – were among the most feared warriors of the medieval world, and were particularly renowned for their deadly skill as mounted archers.
