7+ hour, 30+ min ago   (797+ words) Much of the ancient carbon released from thawing Arctic permafrost appears to end up trapped in seabed sediments rather than quickly returning to the atmosphere. The Arctic’s frozen ground holds an enormous reservoir of organic carbon. As permafrost thaws and…...

14+ hour, 5+ min ago   (857+ words) Common plastic waste could become fuel using heated salts instead of extreme temperatures. Plastic bags, cutting boards, and many other everyday products are made from a plastic that is notoriously difficult to reuse once it becomes waste. Researchers at Oak…...

3+ day, 19+ hour ago   (620+ words) Captive-reared crocodiles adapted well after release, but a translocated wild crocodile showed strong homing instincts, offering new insights for conservation planning. A new study suggests that saltwater crocodiles born or raised in captivity may successfully adapt to life in the…...

4+ day, 3+ hour ago   (119+ words) Using a new computational toolkit, Yale researchers recovered evolutionary clues from highly degraded DNA and identified two extinct lineages of giant tortoises....

5+ day, 17+ hour ago   (1279+ words) Bats’ remarkable ability to withstand decades of strenuous flight while keeping infections, inflammation, and cancer in check may offer new clues to healthier human aging Bats are unusually long-lived for animals of their size. Small mammals generally burn energy quickly…...

6+ day, 18+ hour ago   (649+ words) Africa’s giant herbivores did not simply vanish in a wave of extinctions. Their evolutionary family tree was slowly running out of new branches. A new study suggests that the long decline of animals such as elephants, hippopotamuses, and their extinct…...

6+ day, 19+ hour ago   (866+ words) A mountain of loose rock in Utah hides enough ice to fill 600 Olympic swimming pools, revealing that some of the state’s largest frozen water reserves are almost invisible from the surface. Unlike conventional glaciers, which expose broad expanses of ice,…...

1+ week, 2+ day ago   (110+ words) A tropical warming event helped drive record snowfall and a temporary 695-billion-ton ice gain in East Antarctica without reversing long-term Antarctic ice loss....

1+ week, 2+ day ago   (782+ words) A Manhattan-sized ice island has broken free from Greenland’s Petermann Glacier, and scientists say even bigger breaks may be coming. Europe’s Copernicus Sentinel-1 mission has documented a major breakup at Petermann Glacier in northwest Greenland, where a 76 sq km portion…...

1+ week, 3+ day ago   (1090+ words) Genetic research revealed four distinct gentoo penguin species, including a newly identified species from the Kerguelen Islands. Scientists warn climate change may endanger several isolated island populations. The emperor penguin, which can grow to about 4 feet (1.2 meters) tall, is the…...
