New fossil sheds light on old mystery

...its own size, but by the time the fish was able to see Dinocephalosaurus' body, it would already have been lunch," Dr. LaBarbera said. "Dinocephalosaurus sheds new light on the evolution of protorosaurs and the functional morphology of these long-necked marine reptiles," said Chun Li, lead author and ass...

Groundbreaking research could ignite new solutions to heat transfer in nano-devices

...students. "This project gave me the opportunity to see what my future would be like if I pursue a research track," said Mr. Sechler, a junior who now plans to pursue a Ph.D. in chemistry. The research used vibrational spectroscopy with picosecond time resolution to monitor the flow of energy across surfa...

The poplar consortium researchers plan to publish the results of their analysis early next year. "Carbon management issues are overwhelming, but poplar trees could play a...

UAF scientists discover new marine habitat in Alaska

...never been described in Alaska. We were shocked to see how many there were down there." Konar said she knew right away the find was significant. She'd seen rhodoliths in places like Baja California, Mexico. But in her more than 15 years of diving Alaska waters, she had never come across them. ...

Research suggests new avenue for stopping, preventing colon cancer

... Vanderbilt researchers hope to test it in mice to see if it has the same effect as knocking out the gene. "We've been carefully examining drugs which inhibit COX-2," DuBois explained. "Now we can really focus on key components of the downstream pathway." The research could lead to more specific and saf...

22nd amino acid synthesized and added to genetic code of e. coli bacteria

...it should be," Krzycki said. The final step was to see if the translator enzyme for L-pyrrolysine would function normally within a living cell. To test that, they inserted the enzyme into Escherichia coli bacteria. Researchers use E. coli as an easy test for some basic biological functions. Once inside t...
