Finding hidden invaders in a Hawaiian rain forest

...craft imagery also showed us how the forest canopy chemistry is changing as a result of the invader." The study is published in the March 7-11, 2005, early online edition of the Proceedings of the National Academy of Sciences. The new methods are exciting because they detect effects of biological invasions on...

Biochemists report discovery of structure of major piece of telomerase; implications for cancer

... telomerase works," said Juli Feigon, professor of chemistry and biochemistry at UCLA, who led the research group. "Knowing the structure also will allow the pursuit of rational, structure-based drug design, and is a critical first step. The structure provides a potential target for drug intervention." Feigon...

Researchers make gains in understanding antibiotic resistance

...ale University, and Peter B. Moore, a professor of chemistry at Yale, the research team published its findings in the April 22, 2005, issue of the journal Cell. Steitz and his colleagues studied the structural basis of bacterial resistance to a group of antibiotics that, while chemically quite different, all ...

Use of PET can reduce, may eliminate more strenuous drug development trials with animals

... and drug activity. This imaging tool examines the chemistry and biology of a person's body by monitoring ingested tracer molecules, and it is used to study the metabolism of the brain, the heart and cancer. A miniature version of PET was developed and is used in much the same way to image small animals. Smal...
