A deep-sea microbe uses an exceptionally heat-resistant enzyme to turn atmospheric nitrogen into ammonia at temperatures that would destroy most proteins. Its unusual structure and a newly observed reaction state may reveal an ancient, shared ...

A single-celled organism can shrink to one-quarter of its length in milliseconds using a remarkable calcium-powered protein "fishnet." Scientists hope its unusual machinery could inspire artificial muscles capable of moving far faster than today's .. ...

A 150-million-year-old dinosaur fossil from Spain has been identified as the first confirmed Diplodocus ever found outside North America. The giant sauropod measured about 25 meters long and was preserved well enough for researchers to match ...

Scientists are looking to diatoms, sea sponges, and plants for a cleaner way to recover rare earth elements and other valuable minerals hidden inside coal ash, red mud, and mine tailings. The bio-inspired approach could turn massive industrial waste ...

A newly discovered snake from New Guinea has been named after Guns N' Roses guitarist Slash, who has loved reptiles since childhood. Genetic testing and physical differences confirmed that the reddish-brown groundsnake, Lielaphis slashi, is a species ...

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 .. ...
