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
Claire Fraser-Liggett, Director of the Institute for Genome Sciences and professor at the University of Maryland School of Medicine, gives the June 2, 2010 keynote at the "Sequencing, Finishing, Analysis in the Future" meeting in Santa Fe, NM. 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
The swine flu situation continues to be serious in four of India's southern states and the western state of Maharashtra, which have reported 366 of the 370 H1N1 infections in the last week, official figures show.
Kerala remains the worst affected state with 222 confirmed reports of swine flu.... Read More

In 2007, an estimated 656 million fevers occurred in African children aged 0-4 years, with 78 million children of the 183 million attending a public health care facility likely to have been infected with P. falciparum (range 60-103 million), the parasite that causes the most dangerous form of ma...

Wyss researchers have engineered photosynthetic bacteria to produce simple sugars and lactic acid, an innovation that could lead to new, environmentally friendly methods for producing commodity chemicals in bulk. Because the production methods use photosynthesis -- the process by which living th... Read More
Having an intimate relationship with photosynthetic microbes is a widespread strategy adopted by numerous unicellular and multicellular organisms. Some eschew a committed relationship, and simply nab the plastids, sequestering them inside vacuoles where they continue to photosynthesize for a whi... Read More
As the U.S. struggles with the after effects of the oil spill on tourism, animal health, and food safety due to the largest environmental disaster in U.S. history, microbiologists are stuggling to determine the scope of damage to microbial diversity in the ocean water and sediment.
The explos... 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
