Scientists have created a programmable material that gives engineers unprecedented control over heat, with potential applications ranging from energy systems to next-generation photonic memory. Heat normally follows strict rules. A material that efficiently absorbs heat from a particular direction and wavelength will also emit heat the same way. This fundamental principle, known as reciprocity, has […]
The Universe Was Barely Born When These Giant Black Holes Appeared
Thirty-one newly discovered ancient quasars are giving scientists their clearest view yet of the universe’s earliest giant black holes. Quasars are among the brightest objects in the universe, shining with the power of supermassive black holes consuming vast amounts of matter. Some are so luminous they outshine entire galaxies, allowing astronomers to see them across […]
Scientists Find the Hidden “Fuel” That May Intensify Tropical Clouds
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 […]
