8+ hour, 16+ min ago   (663+ words) Scientists have found that Arctic cyclones become especially destructive when several strike one after another. These storm clusters cause about twice as much sea ice loss as isolated cyclones, with impacts that persist roughly two and a half times longer....

2+ day, 22+ hour ago   (145+ words) High stakes leadership and landing on Mars Cross-border diffusion -- learning from lightning on Venus Why protect bootprints on the Moon? Unlike ancient footprints, cave drawings, and stone-age tools found here on Earth, the first traces of human activity on the…...

3+ day, 9+ hour ago   (781+ words) Scientists have discovered that the Moon-forming collision may have depended heavily on how hot and physically strong early Earth and Theia were. New simulations found that some impacts create the familiar disk of debris that later becomes the Moon, while…...

5+ day, 6+ hour ago   (41+ words) Volcanic rocks in Colombia are rewriting the timeline of the collision between Central and South America. Their magnetic signatures show that major tectonic deformation had already weakened by the late Miocene, suggesting the most intense collision occurred earlier than previously…...

1+ week, 12+ hour ago   (753+ words) A persistent patch of unusually warm tropical ocean helped intensify snowfall over East Antarctica, contributing to a temporary net ice sheet mass gain of about 695 billion tons, according to a new study published in Nature on August 19. A Remarkable Antarctic…...

1+ week, 1+ day ago   (164+ words) 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 sight…...

1+ week, 3+ day ago   (400+ words) A huge 10-sided atmospheric pattern has appeared around Saturn’s south pole, giving the planet a surprising counterpart to its famous northern hexagon. Hubble data suggest the strange decagon only began emerging in the past few years and is still growing…...

1+ week, 5+ day ago   (1049+ words) NASA-funded studies suggest Earth’s climate has been influenced by both the Sun’s travels through dense regions of the Milky Way and the violent superflares of its youth. Those events may help explain ancient ice ages as well as how early…...

1+ week, 6+ day ago   (1058+ words) Computer models are helping scientists explain a puzzling pattern of deformation beneath the East African Rift System. The results point to the African Superplume, a vast upwelling of hot mantle material deep inside Earth, as the source of unusual motion…...

2+ week, 5+ hour ago   (252+ words) Rocky planets may have been able to start forming just 100 million years after the Big Bang, thanks to enormous early supernovae that scattered planet-building elements across space. Simulations found enough solid material and water around a young star to suggest…...
