An antibiotic with the ability to vanquish drug-resistant pathogens has been discovered — through a soil bacterium found just beneath the surface of a grassy field in Maine. Although the new antibiotic has yet to be tested in people, there are signs that pathogens will be slow to evolve resistan... Read More
The polio eradication and endgame strategic plan announced by the World Health Organization in 2014 includes at least one dose of inactivated poliovirus vaccine (IPV). Since 1988, when WHO announced the polio eradication plan, it had relied exclusively on the use of oral poliovirus vaccine (OPV)... Read More
The National Institutes of Health has awarded grants totaling $7.9 million in 2014 to 25 research teams who are unraveling the workings of single cells, as part of an effort to spur development of personalized treatments that target disease at the cellular level. The grants are supported by the ... Read More

Scientists have traditionally studied bacteria in large numbers, not individually. Working with tens of millions of cells in a culture flask, they tracked their growth by looking at how much the cells dimmed light passing through a tube.
Using this method, scientists learned that populations ... Read More

The bacteria that cause cholera grab genes from other organisms in a particularly predatory and precise way, new research finds: They spear neighboring cells with a kind of poison-tipped spike.
Bacteria often grab genes from other organisms and incorporate that DNA into their own genomes. But... Read More
With drug-resistant bacteria on the rise, even common infections that were easily controlled for decades -- such as pneumonia or urinary tract infections -- are proving trickier to treat with standard antibiotics.
New drugs are desperately needed, but so are ways to maximize the effective lif... Read More
A new class of compounds may be an effective way to fight a virus that leaves children with serious respiratory infections and might be associated with polio-like symptoms.
Researchers used a technique called X-ray crystallography to learn the precise structure of the original strain of enter... Read More
