Deep, clean convective clouds can reach high supersaturation levels that may allow aerosols to intensify cloud growth. Tiny aerosol particles can change how clouds behave, but scientists have long debated whether they can actually make tropical storm clouds grow stronger. The question matters because deep convective clouds help shape rainfall, lightning, and climate, yet the […]

Scientists Catch a “Jumping Gene” Moving Between Species
A jumping gene was directly observed moving from predator to prey through circular RNA. Dead cells are usually molecular dead ends: their fragile RNA messages rapidly disappear, and no new genetic activity is expected. But when Jens Harder and his colleagues examined the remains of a methane-producing archaeon, they found an unusually persistent ring of […]
New Study Rewrites the Story of How Humans Got Bigger
Human body size evolution was shaped by both gradual change and a major later growth spurt within Homo. When did our ancestors become human-sized? Scientists have debated for decades whether the human lineage gradually grew larger over millions of years or experienced a dramatic leap in body size. A new study suggests the answer is […]

Just Two Hours of This Simple Exercise Habit a Week May Help You Live Longer
Lifting weights for about one to two hours a week may support longer life, especially when combined with aerobic activity. A few sets with weights may seem like a small part of a weekly routine, but the effects may reach far beyond stronger arms or a more defined physique. Evidence is increasingly pointing to strength […]
Scientists Discover a Hidden Chemical Pathway That Makes City Air Hazy
Nitric oxide may play a larger role in city air pollution than scientists previously thought. City air can look clear one moment and turn hazy the next, but the chemistry behind that change is often hidden molecule by molecule. In traffic corridors, near power plants, and around other combustion sources, nitric oxide (NO) has usually […]
