Animals must wage a never-ending war against parasites, constantly evolving new ways of resisting these threats. Resistance comes in many forms, including genes that allow their owners to shrug off infections. But one species of fly has developed a far more radical solution – it has formed a par... Read More
Two antibodies, VRC01 and VRC02, identified in HIV-infected blood, attach to the CD4 binding site of HIV and appear to prevent the virus from attaching to and infecting T cells, according to new research.

Researchers are using nanotechnology to develop a medical dressing which will detect and treat infection in wounds. Scientists at the University of Bath and the burns team at the Southwest UK Paediatric Burns Centre at Frenchay Hospital in Bristol are working together with teams across Europe an... Read More
You can't see them or smell them (most of the time), yet microbes and germs occupy most of the surfaces around you. Many live on your own skin. In fact, if you're a normal, healthy person you will shed approximately 2 million cells an hour, says Michael G. Schmidt, PhD,Professor of the Departmen... Read More
The transformation of a single cell into a complete animal is amazing and complicated. Cells must divide and migrate through the ever-changing embryo, shaping themselves into specialized organs. And it happens at a blistering pace: a zebrafish embryo, for example, goes from a single cell to 20,... Read More

Within the human digestive tract is a teeming mass of hundreds of types of bacteria, a potpourri of microbes numbering in the trillions that help us digest food and keep bad bacteria in check.
Now scientists have found that the vitamin D receptor is a key player amid the gut bacteria – what s... Read More
Bacteria, which can thrive in places where humans wouldn't dare linger, can be friends or foes. Take E. coli. Some strains are harmless and settle comfortably in animals' lower intestines. Others take free rides in lettuce and end up causing kidney failure and other serious ailments for salad lo... Read More
Scientists studying the so-called "superbug" MRSA have identified one of the components responsible for making it so deadly.
Staphylococcus aureus is a type of bacteria commonly found on the skin that is relatively harmless unless it gets into the bloodstream, where it can cause blood poisoni... Read More

Ear infections caused by more than one species of bacteria could be more persistent and antibiotic-resistant because one pathogen may be communicating with the other, encouraging it to bolster its defenses. Interrupting or removing that communication could be key to curing these infections. Re... Read More
A team of Spanish scientists has studied the bacteria -- micro organisms that are "essential" for important processes such as nitrogen and carbon-fixing and decomposition of matter -- in the Tablas de Daimiel National Park. The scientists discovered 265 new phylum groups by using DNA analysis.

This time of year, allergies and the promise of air-conditioning tend to drive people indoors.
But for those who can take the heat and cope with the pollen, spending more time in nature might have some surprising health benefits. In a series of studies, scientists found that when people swap ... Read More
Sewage that overflows into urban creeks and streams during periods of heavy rain can promote the spread of West Nile Virus, an Emory study finds.
The analysis of six years of data showed that people living near creeks with sewage overflows in lower-income neighborhoods of Southeast Atlanta ha... Read More
Empa researchers have demonstrated how they can adjust process conditions to influence the properties of novel plasma polymer coatings containing silver nanoparticles. Tailor-made films can be generated through a one-step plasma process. The scientists developed these new coatings, which kill ba... Read More
