Whole carcass feeding on a feast and fast schedule encouraged zoo-housed lions to display feeding and activity patterns more similar to those seen in the wild. For lions living in human care, the timing and form of a meal can influence behavior for days. A new Australian study found that giving zoo-housed lions whole animal […]
Where Were All the Tiny Dinosaurs? Scientists May Finally Have an Answer
For all their astonishing diversity, dinosaurs seem to have hit one evolutionary limit: they almost never became truly tiny. Tiny animals are everywhere in modern ecosystems, from mice and shrews to hummingbirds and geckos, yet dinosaurs seem to have left much of that miniature world unexplored. A new study suggests this missing miniature world cannot […]
Astronomers Caught a Star Exploding Almost the Instant It Began
Astronomers witnessed a star’s death almost from the instant it began, catching an extraordinarily rare X-ray flash as a supernova erupted 500 million light-years away. Astronomers rarely get to watch a star die from the beginning. Usually, a supernova is discovered only after the explosion is already well underway. SN 2026gzf was different. On March […]

Humanity May Soon Have the Technology To Reach Other Star Systems
Tiny spacecraft riding beams of light could put humanity within reach of another star system in a single lifetime. The recent confirmation of an atmosphere around a rocky exoplanet called LHS 1140b has created a wave of interest within the astronomy community. The planet orbits within the habitable zone around its parent star—a red dwarf […]
A “Double Punch” Nanoparticle Could Reveal and Destroy Brain Cancer Cells
Light-activated nanoparticles could help surgeons see glioblastoma more clearly and destroy cancer cells that remain after surgery. Glioblastoma can spread microscopic cancer cells into healthy brain tissue, making the most aggressive form of brain cancer exceptionally difficult to remove completely. Surgeons must eliminate as much of the tumor as possible without damaging surrounding areas that […]
