The Surinam toad is a fully aquatic Amazonian frog that senses prey with star-shaped fingertips and carries its young in pockets on its back until they emerge fully formed.
Swiss glaciers lost 5.5% of their ice volume in 2026, the second-worst year on record, with nearly 20% of total glacial ice gone in five years and long-term water supply risks ahead.
A NASA satellite built for oceans and lakes can unexpectedly track water levels in most irrigation canals across Asia, offering a new tool for global water management.
New MEGATRON simulations link JWST's view of early galaxies with chemical fingerprints in ancient Milky Way stars, bridging two windows into the first stars.
Injected human dementia tau proteins vanished within a week, but left a structural legacy that mouse tau copied for months, direct evidence of prion-like templating.
A giant clam shell from the Great Barrier Reef records month-by-month climate conditions from 200 years ago, revealing cooler summers and similar winters before industrial warming.
Philadelphia computer scientist Chinyere Ukeje wins NASA's $300,000 Mars to Table prize with a modular food system for growing and cooking meals on the Red Planet.
Antarctic winter sea ice peaked at its third-lowest level on record on September 14, marking the fourth consecutive year of historically low maximums, scientists report.
