...t and more adapted for forceful bites and shearing flesh than are those of modern wolves. They also showed a higher incidence of broken teeth than living wolves. Taken together, these features suggest a wolf specialized for killing and consuming relatively large prey, and also possibly habitual scavengi...

...migrations along the California coast. While the flesh of a dead whale decomposes within weeks, the bones can last anywhere from 60 to 100 years. "As that happens, the bacteria that break down the bones release sulfur," Daly said. "A whole community of aquatic creatures uses that sulfur to make energy,...

The new system, dubbed CTX, will combine the 3-D capability of CT scanners and the real-time movement tracking of cinefluoroscopy. CTX technology is expected to deliver images with exceptional precision and detail. Research...

Scientists find mutations that let bird flu adapt to humans

...nize the receptors on avian cells. The work helps flesh out the changes that have occurred in the worrisome strain of avian influenza virus known as H5N1, a strain some fear could be the organism that will trigger a pandemic of virulent human influenza. The avian virus has already changed dramatically fro...

Mixing exploitation and conservation: A recipe for disaster

A much greater proportion would survive if their gizzard could expand by at least 1 gram (70% for 1 gram, 88% for 2 grams). These degraded food conditions, the authors conclude,...

Medical steroid's baffling connection to osteoporosis becomes clearer

... between osteoporosis and cortisone. As scientists flesh out the molecular-level details of this connection, they may be able to identify targets for therapy to prevent cortisone's damaging side effects on bone. "High-dose cortisone is the second most common cause of osteoporosis, and we currently have n...

In a way, said Moore, these studies are a scientific way to explain the regenerative process told in that legend. Others who participated...

Evolution mystery: Spider venom and bacteria share same toxin

The authors discovered that fangblenny mimics were more successful in attacking victims on reefs where they were much rarer than cleanerfish. Rarity probably favours mimics because potential victims encounter a...
