An ancient mountain cave in the Pyrenees may have served as one of the earliest high-altitude mining camps ever discovered, with evidence of repeated visits spanning thousands of years。 The find becomes even more intriguing with the discovery of a child’s remains and clues that deeper excavations could uncover prehistoric burials
Scientists at Lawrence Livermore National Laboratory recreated part of the intense chaos inside a nuclear fireball to better understand how radioactive fallout forms。 Their experiments revealed that the way vaporized materials cool can dramatically change the particles that eventually form, especially for volatile elements like cesium
A newly discovered genetic clock acts as the master timekeeper for development, orchestrating crucial bursts of gene activity throughout a worm’s growth。 When the clock is disrupted, development stops, offering fresh clues about how growth-related disorders may arise
NASA's James Webb Space Telescope has uncovered unusual chemistry in interstellar comet 3I/ATLAS, including the first direct detection of methane on a visitor from another star system。 The comet also contains exceptionally high levels of carbon dioxide, making it unlike most comets born in our solar system。 Scientists believe the methane was hidden
Hidden beneath Arctic waters, beluga whales have long kept their family lives a mystery。 By analyzing DNA from more than 600 belugas in Alaska’s Bristol Bay over 13 years, researchers uncovered a surprisingly flexible mating system: both males and females regularly have offspring with different partners over their lifetimes
A long-overlooked organ may hold surprising clues to healthy aging and cancer survival。 Researchers at Mass General Brigham used AI to analyze CT scans from tens of thousands of adults and found that people with healthier thymuses—a small immune-system organ once thought to become largely irrelevant after childhood—lived longer and had substantiall
Researchers discovered a way to reverse the direction of energy flow in turbulence, challenging a theory that has stood for more than 80 years。 The finding could open new possibilities for controlling ocean currents, improving medical technologies, and enhancing climate forecasting
