Researchers discover HVEM’s unknown role in fighting off E. coli infections

Despite ongoing public health efforts, E. coli outbreaks continue to infiltrate the food supply, annually causing significant sickness and death throughout the world. But the research community is gaining ground. In a major finding, published today in the scientific journal Nature, researchers from the La Jolla Institute for Allergy & Immunology have discovered a molecule's previously unknown role in fighting off E. coli and other bacterial infections, a discovery that could lead to new ways to protect people from these dangerous microorganisms.

Global warming may stimulate growth of cyanobacteria

Cyanobacteria are among the most primitive living beings, aged over 3,500 million years old. These aquatic microorganisms helped to oxygenate the earth-atmosphere. At present their populations are increasing in size without stopping. It appears that global warming may be behind the rise in their numbers and may also lead toan increase in the amount of toxins produced by some of these populations.

Study reveals technique that allows scientists to watch lipid metabolism in live zebrafish

In mammals, most lipids are absorbed into the body via the small intestine. The complexity of the cells and fluids that inhabit this organ make it very difficult to study in a laboratory setting. New research from Carnegie's Steven Farber, James Walters and Jennifer Anderson reveals a technique that allows scientists to watch lipid metabolism in live zebrafish. This method enabled them to describe new aspects of lipid absorption that could have broad applications for human health.

Dietary fiber can improve gastrointestinal health

A University of Illinois study shows that dietary fiber promotes a shift in the gut toward different types of beneficial bacteria. And the microbes that live in the gut, scientists now believe, can support a healthy gastrointestinal tract as well as affect our susceptibility to conditions as varied as type 2 diabetes, obesity, inflammatory bowel disease, colon cancer, and autoimmune disorders such as rheumatoid arthritis.

Link between bacterial vaginosis and female-to-male HIV transmission risk

An investigation led by UCSF has found that the risk of female-to-male HIV transmission is increased three fold for women with bacterial vaginosis, a common disorder in which the normal balance of bacteria in the vagina is disrupted.

Study reviews role of gut microbes in nutrient absorption and energy regulation

Microorganisms in the human gastrointestinal tract form an intricate, living fabric made up of some 500 to 1000 distinct bacterial species, (in addition to other microbes). Recently, researchers have begun to untangle the subtle role these diverse life forms play in maintaining health and regulating weight.

New photoactive compound eradicates 'Iraqibacter' from wounds and skin infections

Researchers at the University of California, Santa Cruz, have developed a novel approach for eradicating drug-resistant bacteria from wounds and skin infections, using light to trigger the controlled release of nitric oxide. The UCSC team developed a photoactive compound that releases nitric oxide when exposed to light, and loaded it into a porous, biocompatible material that could be applied as a sprayable powder.
