A drug used to treat lymphoma, rheumatoid arthritis and other immune disorders may enable newly-diagnosed type 1 diabetics to save some of their pancreas function and thereby reduce their susceptibility to long-term complications.   view more (2006-03-16)

Pair of studies offer new clues to combat antibiotic resistance
In the continuing battle against antibiotic resistance, two new studies shed light on the complex defense mechanisms pathogenic bacteria use to evade antibiotic attack, an understanding of which could lead to new, more effective antibiotics to help save lives and combat the growing problem of... view more (2006-01-25)

Locusts' built-in 'surface analysis' ability directs them to fly overland
Swarms of millions of locusts have, since Biblical times and until our very own day, been considered a "plague" of major proportions, with the creatures destroying every growing thing in their path.   view more (2005-08-12)

A wolf in sheep's clothing: plague bacteria reveal one of their virulence tricks
The bacterium that causes the plague belongs to a virulent family of bacteria called Yersinia, a group that also includes a pathogen responsible for food poisoning.   view more (2006-09-21)

Bacteria control how infectious they become, study finds
The results of a new study suggest that bacteria that cause diseases like bubonic plague and serious gastric illness can turn the genes that make them infectious on or off.   view more (2007-04-13)

Researchers discover key gene involved in bark beetle pheromone production
University of Nevada, Reno scientists have ended a decade-long controversy over the process by which bark beetles make pheromones: they manufacture their own monoterpenes - the fragrant substances plants produce and which are often used in perfumes.   view more (2005-06-28)
