As demand for critical metals grows, scientists have taken a rare, close look at life on the deep Pacific seabed where mining may soon begin. Over five years and 160 days at sea, researchers documented nearly 800 species, many previously unknown. ...

SAR11 bacteria dominate the world's oceans by being incredibly efficient, shedding genes to survive in nutrient-poor waters. But that extreme streamlining appears to backfire when conditions change. Under stress, many cells keep copying their DNA ...

MACE is a next-generation experiment designed to catch muonium transforming into its antimatter twin, a process that would rewrite the rules of particle physics. The last search for this effect ended more than two decades ago, and MACE plans to leap ...

NASA's SpaceX Crew-12 team has entered a carefully controlled two-week quarantine as the countdown begins for their journey to the International Space Station. The four astronauts--representing NASA, the European Space Agency, and Roscosmos--are ...

Hidden lava tunnels on the Moon and Mars could one day shelter human explorers, offering natural protection from radiation and space debris. A European research team has unveiled a bold new mission concept that uses three different robots working ...

A newly detected gravitational wave, GW250114, is giving scientists their clearest look yet at a black hole collision--and a powerful way to test Einstein's theory of gravity. Its clarity allowed scientists to measure multiple "tones" from the ...

Despite growing into the largest animals ever to walk on land, sauropods began life small, exposed, and alone. Fossil evidence suggests their babies were frequently eaten by multiple predators, making them a key part of the Jurassic food chain. This ...

When the brain rests, it usually replays recent experiences to strengthen memory. Scientists found that in Alzheimer's-like mice, this replay still occurs -- but the signals are jumbled and poorly coordinated. As a result, memory-supporting brain ...

Middle age is becoming a tougher chapter for many Americans, especially those born in the 1960s and early 1970s. Compared with earlier generations, they report more loneliness and depression, along with weaker physical strength and declining memory. ...

Old Indian poems and folk songs are revealing a surprising truth about the land. Scientists found that descriptions of thorny trees and open grasslands in texts written as far back as the 1200s closely match today's savannas in western India. This .. ...
