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

Just when we think we know everything, a story comes along to remind us that there is something fundamental--and seemingly elementary--that we still haven't figured out. “Why are we the size we are? Why are our organs the size they are? Why are the cells in those organs a stereotypical size? Wha... 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
The TWiV gang reviews ten fascinating, compelling, and riveting virology stories from 2014.
Shown here is a picture of a hookworm egg found on a concentrate in an ova & parasite exam
Human hookworms include the nematode species, Ancylostoma duodenale and Necator americanus. These species have indistinguishable eggs and can only be distinguished by their larvae.
Infective larvae g... Read More
