Revealing a pollutant's Achilles' heal

Nitric oxide (NO) is a versatile free radical that plays central roles in the environment as well as living organisms. At low concentration in the human body, for example, NO protects organs against pathogens by acting as ...

New antibiotic could make food safer and cows healthier

Food-borne diseases might soon have another warrior to contend with, thanks to a new molecule discovered by chemists at the University of Illinois. The new antibiotic, an analog of the widely used food preservative nisin, ...

Coral reefs in warming seas

Disease outbreaks are often associated with hot weather. Because many bacteria typically multiply more rapidly in warmer conditions, it's a commonly held notion that warm-weather outbreaks are a straightforward consequence ...

New compound defeats drug-resistant bacteria

It's no wonder that medicine's effort to combat bacterial infections is often described as an arms race. When new drugs are developed to combat infections, the bacterial target invariably comes up with a deterrent.

Triple threat: One bacterium, three plasmids

Researchers from Australia found something completely new while conducting a genetic study of the pathogenesis of an enteric disease in birds. They report what is believed to be the first bacterial strain to carry three closely ...

Study presents new insight into plant immunity

Researchers have identified an important cog in the molecular machinery of plant immunity - a discovery that could help crop breeders produce disease-resistant varieties to help ensure future food security. There may also ...
