...sponsible for their bright red feathers. The work casts a new light on what is chemically responsible for the colors of birds, and defies previous assumptions and explanations for color variations in parrots, said Kevin McGraw, an assistant professor in ASU's School of Life Sciences.

Scientists use manufacturing methods to reconstruct mastodon

... the exhibit will be assembled from the fiberglass casts so that researchers can continue studying the real bones, which are on loan to the museum from the Buesching family. When complete, the exhibit will be significant for a number of reasons, Fisher said. "To my knowledge it will be the only display in...

Revueltosaurus skeleton unearthed at Petrified Forest upsets dinosaur tale

...tion to determine what is an early dinosaur, which casts doubt on all the ornithischians from the Triassic of North America." This suggests, he said, that the herbivorous ornithischians and the meat-eating theropods, like Tyrannosaurus rex, did not evolve together in the Late Triassic as many paleontologi...

MSKCC researchers uncover structure of key protein complex in cells

...itions in which SUMO is involved." The study also casts light on a poorly understood aspect of cellular communication. The MSKCC researchers believe the protein complex they have observed is assembled at nuclear pore complexes, portals that connect the nucleus with the cytoplasm beyond. These conduits per...

Did feathered dinosaurs exist?

...nt from that in theropod dinosaurs," they say, and casts doubt upon the theropod derivation hypothesis. Finally, they discuss the significance of the Chinese discoveries with respect to bird origin and flight. The authors emphasize that the totality of evidence from various branches of science must be in...

Ocean seep mollusks may share evolutionary history with other deep-sea creatures

...e Eocene age calculated by the Science researchers casts some doubt on another mystery involving seep animals: what is their relationship to whale falls? Whale falls, the slowly decaying remains of large whales sunk to the ocean's depths, harbor yet another unique chemical community similar to that in vent...

A buffet for early human relatives

...ried diet ?survived and evolved. The new study casts doubt on that theory by showing that Paranthropus, like Homo, also consumed a variety of foods. "Thus, other biological, social or cultural differences may be needed to explain the different fates of Homo and Paranthropus," the scientists conclud...
