Germ-killing nanosurface opens up new front in hygiene (Update)
Imagine a hospital room, door handle or kitchen countertop that is free from bacteria—and not one drop of disinfectant or boiling water or dose of microwaves has been needed to zap the germs.
Garlic counteracts virulent bacteria
Garlic contains a substance that is particularly effective in encounters with even the hardiest bacterial strains. A young researcher at the University of Copenhagen will soon be defending his Ph.D. thesis on the positive ...
Genetically identical bacteria can behave in radically different ways
Although a population of bacteria may be genetically identical, individual bacteria within that population can act in radically different ways.

How zinc starves lethal bacteria to stop infection
(Phys.org) —Australian researchers have found that zinc can 'starve' one of the world's most deadly bacteria by preventing its uptake of an essential metal.
Rare sugars are good for you
Rare sugars prevent dental caries, heal infections and sweeten with few calories.
Dispersal patterns key to invasive species' success
In 1859 an Australian farmer named Thomas Austin released 24 grey rabbits from Europe into the wild because it "could do little harm and might provide a touch of home, in addition to a spot of hunting."
'Superbugs' found breeding in sewage plants
(Phys.org) —Tests at two wastewater treatment plants in northern China revealed antibiotic-resistant bacteria were not only escaping purification but also breeding and spreading their dangerous cargo.
Researchers discover bacteria thrive in zero-gravity low nutrient environment
No peak in sight for evolving bacteria
There's no peak in sight – fitness peak, that is – for the bacteria in Richard Lenski's Michigan State University lab.
A new weapon in the war against superbugs
