    Scientists just captured trees glowing with electricity during storms

    Scientists chasing thunderstorms in a retrofitted minivan finally captured something never seen before in nature: faint electrical glows shimmering from treetops during a storm. These “corona discharges,” long suspected but never observed outside a lab, appeared as tiny UV flashes at the tips of leaves. The discovery could reshape how we understand forests, since these bursts may help clean the air by breaking down pollutants.

    These tiny dinosaur fossils fooled scientists for 20 years

    Tiny dinosaur fossils that puzzled scientists for over 20 years have finally revealed their true identity. Rather than belonging to a miniature species, they are actually baby ankylosaurs—some less than a year old, including a possible hatchling. By studying bone growth patterns, researchers confirmed these young dinosaurs hadn’t yet developed into full-sized adults. The discovery sheds new light on how ankylosaurs grew, showing they began developing armor surprisingly early.
