Leprosy genome tells story of human migrations, French researchers report in Science

A French genetics study comparing strains of leprosy-causing bacteria has revealed some surprises about how the pathogen evolved and how it was spread across the continents by human migrations. The research, led by scientists at the Pasteur Institute in Paris, appears in the 13 May issue of the journal Science, published by AAAS, the nonprofit science society. The findings indicate that t...

Immune system's distress signal tells bacteria when to strike back

The human opportunistic pathogen, Pseudomonas aeruginosa, has broken the immune system's code, report researchers from the University of Chicago, enabling the bacteria to recognize when its host is most vulnerable and to launch an attack before the weakened host can muster its defenses. In the 29 July 2005 issue of Science, the researchers show how this lethal organism detects interferon-g...

'Exercise pill' switches on gene that tells cells to burn fat

By giving ordinary adult mice a drug - a synthetic designed to mimic fat - Salk Institute scientist Dr. Ronald M. Evans is now able to chemically switch on PPAR-d, the master regulator that controls the ability of cells to burn fat. Even when the mice are not active, turning on the chemical switch activates the same fat-burning process that occurs during exercise. The resulting shift in energy b...

DNA from feathers tells tale of eagle fidelity

A trail of feathers led a team of Purdue University scientists to confirm that eagles from central Asia are quite possibly the most faithful of birds. By performing DNA analysis on the feathers left behind at nesting sites, the researchers were able to identify individual Eastern imperial eagles in a nature reserve in Kazakhstan. Their analysis showed that not one adult strayed from its ma...

Researchers find gland that tells fruit flies when to stop growing

Many baffled parents have wondered whether their teenagers would ever stop growing. The answer is obvious, but researchers have never really quite understood just how an organism determines when it has reached its optimal size and growth should cease. Now University of Washington biologists studying the physiology of Drosophila melanogaster, the common fruit fly, have discovered an organ t...
