Scientists may have solved the mystery of why Antarctica froze millions of years before the Arctic. Slow-moving waves deep inside Earth gradually lifted East Antarctica, building mountains and a high plateau where snow and ice could survive even in a ...

A huge section of Greenland's Petermann Glacier has snapped off, forming an ice island about the size of Manhattan. Satellites watched cracks spread rapidly before the 76-square-kilometer slab finally broke free on August 4. It is the glacier's ...

Scientists have created a highly efficient catalyst that breaks down stubborn lignin from plant waste into useful chemicals under relatively mild conditions. By revealing exactly how the catalyst works at the atomic level, the discovery could help .. ...

A sweeping analysis of thousands of animal genomes suggests that chromosomes do not evolve randomly but instead follow a limited number of irreversible "evolutionary highways." These one-way genetic changes preserve clues to more than 600 million ...

NASA scientists found that microbes brought by astronauts could survive in cold, shadowed niches around the Moon's South Pole, potentially complicating future searches for pristine lunar chemistry. Some refuges may be no larger than a footprint, ...

Backyard bird feeders could become unexpected hotspots for H5N1 as Australia's bird flu outbreak spreads, bringing species together in ways that rarely occur naturally. Experts say stopping feeding is safest, while smaller amounts of food, no hand .. ...

Scientists discovered a small, yellowish mountain horned dragon in Thailand and named it Acanthosaura syrax after a dragon from House of the Dragon. Found only in a narrow band of high-elevation forest, the distinctive new species could become a ...

An abandoned farm field became a flourishing wildflower meadow within little more than a decade, with plant diversity doubling and thousands of orchids appearing naturally. The discovery suggests that simply giving nature time to recover could be a . ...

Researchers have used AI to uncover the DNA signature of a key genetic "switch" involved in turning genes on. After analyzing about 500,000 DNA sequences, the model identified the initiator in roughly 60% of human genes. The breakthrough could help . ...

Greenland sharks may live for 400 years without suffering the kind of retinal decline normally associated with aging. Researchers found healthy eye tissue and active proteins specially adapted for seeing blue light in the dim Arctic depths. DNA ...
