East Antarctica gained an astonishing 695 billion tons of ice between 2021 and 2023, temporarily slowing Antarctica's long-term decline. Researchers found that warming thousands of miles away in the tropical ocean altered atmospheric circulation and ...

Indonesia's dangerous peat fires are surging early in the 2026 fire season as a strengthening El Niño and severe drought dry out wetlands that can burn underground for months. These slow smoldering fires are especially destructive because they ...

Archaeologists have identified tiny 80,000-year-old projectile points in Uzbekistan that may have been used like arrowheads. Their size, design, and impact damage closely resemble weapons found much later at a Homo sapiens site in France. The ...

A common frog found across Ecuador and Colombia has finally been recognized as its own species after more than a century of mistaken identity. Museum specimens from the 1800s helped scientists reveal that Pristimantis milpe had been hiding in plain . ...

Researchers at UC San Diego have demonstrated that a key cellular enzyme can accurately read an eight-letter genetic alphabet, doubling the four letters used by all known life on Earth. Detailed imaging revealed that RNA polymerase handles synthetic ...

Scientists have overturned a leading explanation for why male and female bonnethead sharks have differently shaped heads. Instead of males developing a pointed snout at maturity, both sexes actually begin with more pointed heads that become rounder . ...

A substance found in edible sea squirts appeared to reverse several signs of aging in older mice. Plasmalogen supplements improved memory and learning, strengthened connections between brain cells, reduced inflammation, and even helped the mice grow ...

Puerto Rico's normally rainy season has instead brought a severe and fast-growing drought. By August 25, three-quarters of the territory was in at least moderate drought, with extreme drought covering 44 percent and some areas receiving less than 20 ...

MIT researchers have created bacterial "transistors" that can be wired together into living circuits capable of performing calculations and directing chemical signals. One day, these biological computers could coat plant roots or leaves, detecting .. ...

A giant iceberg measuring more than 76 square kilometers broke from Greenland's Petermann Glacier in August 2026, marking the Arctic's largest glacier calving event since 2020. The berg later slammed into Joe Island but survived without breaking ...
