Fish flu: Genetics approach may lead to treatment Posted: 09 Nov 2011 01:13 PM PST A research team has provided the first look at a genetic structure that may play a critical role in the reproduction of the infectious salmon anemia virus (ISAV), more commonly known as the "fish flu."

Obese monkeys lose weight on drug that attacks blood supply of fat cells Posted: 09 Nov 2011 11:30 AM PST Obese rhesus monkeys given an experimental anti-obesity drug lost on average 11 percent of their body weight over four weeks. The targeted combination drug selectively attacks blood vessels that support white fat.

First of its kind gene map of sulfate-reducing bacterium created Posted: 09 Nov 2011 09:57 AM PST Critical genetic secrets of a bacterium that holds potential for removing toxic and radioactive waste from the environment have been revealed in a new study. Researchers have created a first-of-its-kind gene map of Desulfovibrio vulgaris, which can be used to identify the genes that determine how these bacteria interact with their surrounding environment.

Chemists reveal the force within you: New method for visualizing mechanical forces on cell surface Posted: 09 Nov 2011 08:58 AM PST A new method for visualizing mechanical forces on the surface of a cell provides the first detailed view of those forces, as they occur in real-time. Emory chemists were able to measure something that's never been measured before: The force that one molecule applies to another molecule across the entire surface of a living cell, and as this cell moves and goes about its normal processes.

Biologists slow the aging process in fruit flies: Study has implications for humans Posted: 09 Nov 2011 06:39 AM PST Biologists have identified a gene that slows the aging process. The biologists, working with fruit flies, activated a gene called PGC-1, which increases the activity of mitochondria, the tiny power generators in cells that control cell growth and tell cells when to live and die.
