A study has revealed that 48% of soda fountains at fast food restaurants contain coliform bacteria--a bacteria that grows in feces. And 11% contained E. Coli. Other microorganisms included species of Klebsiella, Staphylococcus, Stenotrophomonas, Candida, and Serratia. Most of them showed resistance to one or more of the 11 antibiotics tested.

Scientists at The Methodist Hospital Research Institute in Houston recently discovered a simple gene mutation that decreases the chance people will get a flesh-eating disease called necrotizing fasciitis. Further, they proved that inactivating this section of the gene lessens the devastating disease in humans.

A discovery by scientists at the Univ. of East Anglia could contribute to the development of systems that use domestic or agricultural waste to generate clean electricity. The researchers have demonstrated for the first time the mechanism by which some bacteria survive by breathing rocks. Fuel cells, or ‘bio-batteries’, powered by animal or human w

UCLA Henry Samueli School of Engineering and Applied Science have genetically modified a cyanobacterium to consume carbon dioxide and produce the liquid fuel isobutanol, which holds great potential as a gasoline alternative. The reaction is powered directly by energy from sunlight, through photosynthesis.

Switching from a low-fat, plant-based diet to one high in fat and sugar alters the collection of microbes living in the gut in less than a day, with obesity-linked microbes suddenly thriving, according to new research at Washington Univ. School of Medicine in St. Louis. The study was based on transplants of human intestinal microbes into germ-free.

Sharklet Technologies, a Florida-based biotech company, has figured out a way to capitalize on shark skin - specifically on the way parasites and bacteria can't stick to sharks. The trick is in the pattern of the skin's surface. Scientists have figured out how to print the pattern onto adhesive film, which wards off bacteria and is ideal for...

A team at the Boston-based college have created microbial fuel cell (MFC) batteries that derive energy from naturally occurring bacteria in soil. If the product takes off, the eco-friendly batteries could provide power for some of the 500 million people in sub-Saharan Africa who lack access to electricity.
