Plankton are the unseen drivers of life on Earth. These microscopic organisms produce a large share of the planet’s oxygen and form the base of the ocean food chain. They are also astonishingly diverse, with tens of thousands of species already identified and many more waiting to be discovered. Among them, protists — tiny, single-celled…

After nearly a quarter century of investigation, scientists have solved a remarkable mystery. Europe’s largest bat doesn’t merely snack on small birds — it hunts and captures them more than a kilometer above the ground and consumes them while still in flight. An international research team has uncovered how this massive bat hunts and eats…

Could everything we thought we knew about T. rex growth be wrong? A remarkably complete tyrannosaur skeleton has brought new clarity to one of paleontology’s longest debates: whether Nanotyrannus was its own species or merely a young Tyrannosaurus rex. The fossil comes from the famous “Dueling Dinosaurs” discovery in Montana, which preserved two creatures locked…

Disrupting communication between the body’s internal clock and the brain could help limit neurodegeneration in Alzheimer’s disease, according to new research from Washington University School of Medicine in St. Louis (WashU Medicine). The study, published in Nature Aging, explored how changes in the circadian system affect brain health and memory in mouse models of Alzheimer’s…

Scientists in Japan have discovered Physalia mikazuki, a previously unknown species of Portuguese man-of-war, in northern waters for the first time. DNA and anatomical analysis confirmed it as distinct from tropical relatives. Ocean simulations suggest warming currents transported it northward, offering new clues about changing ecosystems. The find underscores both marine adaptation and safety concerns…

For nearly 100 years, scientists have been intrigued by the fossils of Paranthropus robustus, a sturdy, distant cousin of early humans. This upright-walking hominin was built for chewing tough foods, equipped with powerful jaws and large teeth coated in thick enamel. Researchers believe it lived in southern Africa between 2.25 million and 1.7 million years…
