In a stellar nursery 460 light-years away, astronomers sharpened old ALMA data and spotted crisp rings and spirals swirling around 27 infant stars--evidence that planets start taking shape just a few hundred thousand years after their suns ignite, .. ...

Wildfires are becoming more intense and dangerous, but a new Stanford-led study offers hope: prescribed burns--intentionally set, controlled fires--can significantly lessen their impact. By analyzing satellite data and smoke emissions, researchers .. ...

Footprints found in the ancient lakebeds of White Sands may prove that humans lived in North America 23,000 years ago -- much earlier than previously believed. A new study using radiocarbon-dated mud bolsters earlier findings, making it the third ...

India's complex ancestry--intertwined with Iranian farmers, Steppe herders, and local hunter-gatherers--has now been decoded through genomic data from 2,762 people. The study uncovers surprising levels of Neanderthal and Denisovan DNA, and how ...

Deleting a gene called PTEN in certain brain cells disrupts the brain's fear circuitry and triggers anxiety-like behavior in mice -- key traits seen in autism. Researchers mapped how this genetic tweak throws off the brain's delicate balance of ...

USC researchers have found a promising new brain scan marker that could better detect Alzheimer's risk -- but only for some. The tau-based benchmark works in Hispanic and White populations when paired with another Alzheimer's protein, amyloid, but .. ...

Scientists have uncovered a surprising new way that urea--an essential building block for life--could have formed on the early Earth. Instead of requiring high temperatures or complex catalysts, this process occurs naturally on the surface of tiny .. ...

Parts of New Orleans are sinking at alarming rates -- including some of the very floodwalls built to protect it. A new satellite-based study finds that some areas are losing nearly two inches of elevation per year, threatening the effectiveness of .. ...

A newly discovered radio halo, 10 billion light-years away, reveals that galaxy clusters in the early universe were already steeped in high-energy particles. The finding hints at ancient black hole activity or cosmic particle collisions fueling this ...

A surprising discovery from a tiny grain of asteroid Ryugu has rocked scientists' understanding of how our Solar System evolved. Researchers found djerfisherite--a mineral typically born in scorching, chemically reduced conditions and never before .. ...
