Anak Krakatau erupted for more than 24 hours in early September, sending volcanic ash up to 50,000 feet into the atmosphere. The ash cloud shut down eight airports, disrupted nearly 3,000 flights, and affected air quality as far away as Jakarta. NASA ...

Arctic sea ice may move in unexpected ways because individual ice floes are constantly colliding and transferring energy. Researchers found that this simple process can explain several long-standing mysteries about how quickly the ice moves and ...

Scientists discovered a new frog species in the flooded forests of the western Amazon, distinguishing it from nearly identical relatives through DNA and its unique call. Adenomera varcena highlights how much Amazonian biodiversity remains hidden even ...

Scientists have developed a solar-powered desalination system that turns seawater into fresh water while removing nearly all of the leftover salt as a solid instead of producing harmful brine. The self-cleaning technology could also recover valuable ...

A newly identified 240-million-year-old animal from Tanzania is forcing scientists to rethink the early dinosaur timeline. Dinodontosaurus isiyavamanda belongs to a group previously known only from South America, linking fossil deposits on the two .. ...

U.S. irrigation produces some greenhouse gas emissions, but new research suggests it prevents vastly more by allowing farmers to grow more food on less land. Without irrigation, replacing lost crop yields could require converting natural ecosystems . ...

A new study suggests Earth formed almost entirely from material in the inner Solar System, challenging the idea that water-rich material from beyond Jupiter played a major role. If correct, Earth's water may have been present much closer to the young ...

The Hunga Tonga eruption may have triggered a surprising chemical reaction that destroyed some of the methane released into the atmosphere. Scientists say the discovery could reshape estimates of methane pollution and inspire new methods for slowing ...

Microscopic plant remains are revealing how GunaiKurnai ancestors used Cloggs Cave for ritual practices over thousands of years. People deliberately gathered whole grasses, carried them into the dark cave, and burned them in thin layers, leaving ...

A 125-million-year-old crocodile fossil has revealed preserved skin, possible sensory organs, sophisticated respiratory structures, and an unexpected pattern on its tail. Ultraviolet light exposed alternating bands that may represent ancient ...
