Arctic permafrost thaw plays greater role in climate change than previously estimated

Abrupt thawing of permafrost will double previous estimates of potential carbon emissions from permafrost thaw in the Arctic, and is already rapidly changing the landscape and ecology of the circumpolar north, a new CU Boulder-led study finds. Permafrost, a perpetually frozen layer under the seasonally thawed surface layer of the ground, affects 18 million square … Read more

Satellite, drone photos could help predict infections of a widespread tropical disease

Satellite images, drone photos and even Google Earth could help identify communities most at risk for getting one of the world’s worst tropical diseases. A team led by the University of Washington and Stanford University has discovered clues in the environment that help identify transmission hotspots for schistosomiasis, a parasitic disease that is second only … Read more

‘MasSpec Pen’ for accurate cancer detection during surgery

A major challenge for cancer surgeons is to determine exactly where a tumor starts and where it ends. Removing too much tissue can impair normal functions, but not taking enough can mean the disease could recur. The “MasSpec Pen,” a handheld device in development, could someday enable surgeons to distinguish between cancerous and healthy tissue … Read more

To avoid injury from male-to-male contests, some animal species display behaviours such as color changes or sequences of movements that showcase body size and … Read more

Adelphi, OHIO researchers determine dinosaur replaced teeth as fast as sharks

A meat-eating dinosaur species (Majungasaurus) that lived in Madagascar some 70 million years ago replaced all its teeth every couple of months or so, as reported in a new study published today in the open-access journal PLOS ONE, surprising even the researchers. In fact, Majungasaurus grew new teeth roughly two to thirteen times faster than those of other … Read more
