UK-led study reveals hidden massive star clusters deep inside nearby galaxies
Astronomers using the VLA and ALMA uncovered previously unseen giant star clusters, described as "ring factories," embedded within nearby galaxies. A complementary analysis of roughly 18,000 star‑forming regions showed that the energetic activity of young stars plays a decisive role in shaping galaxy evolution.

The Travels of Straight-Tusked Elephants in Europe, Written in Their Teeth
A new study in Science Advances examined fossil tooth enamel from straight‑tusked elephants (Palaeoloxodon antiquus) at the 125,000‑year‑old Neumark Nord site in Germany. By combining carbon and strontium isotope ratios with paleoproteomic data, researchers identified distinct migration patterns, showing two males traveled up to 186 miles from distant habitats. The findings confirm that Pleistocene European elephants exhibited long‑distance movements comparable to modern African and Asian elephants. All four individuals ultimately fell prey to Neanderthals, who used their bones for tools.
