Bacterial colonies evolve amazing diversity

Like human societies—think New York City—bacterial colonies have immense diversity among their inhabitants, often generated in the absence of specific selection pressures, according to a paper published ahead of print ...

Sharpening a test for tracing food-borne illness to source

Research from the University of Melbourne, Australia, could make it easier for public health investigators to determine if a case of food poisoning is an isolated incident or part of a larger outbreak. The findings are published ...

Newly discovered mechanism could regulate gene activity

Many bacterial species have genes called mraZ and mraW, which are located in a cluster of genes that regulate cell division and cell wall synthesis. Despite the prevalence of these two genes, very little is known about their ...

Are bacteria making you hungry?

Over the last half decade, it has become increasingly clear that the normal gastrointestinal (GI) bacteria play a variety of very important roles in the biology of human and animals. Now Vic Norris of the University of Rouen, ...

Researchers tap into genetic reservoir of heat-loving bacteria

(Phys.org) -- The identification of key proteins in a group of heat-loving bacteria by researchers at the Department of Energy's BioEnergy Science Center could help light a fire under next-generation biofuel production.
