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.
