The protein LIMP-2 is vital for both humans and animals. If it is absent – due, for example, to a hereditary disease – substances of an unknown nature, probably lipids, accumulate in the organism. Up to now, scientists were unsure what the protein looks like and how exactly it functions. Privatd... Read More
Small shifts in agricultural practices can increase or reduce the risk of salmonella and listeria contamination on produce, new research shows.
For example, applying manure within a year of harvesting produce boosts the odds of contaminating a field with salmonella, which is the biggest singl... Read More
Two subtypes of human papillomavirus (HPV) prevented by vaccines are half as likely to be found in African-American women as in white women with precancerous cervical lesions, according to researchers at Duke Medicine.
The findings, presented on Oct. 28, 2013, at the 12th annual International... Read More
This episode: Bacteria in a volcanic mudpot require rare earth elements to grow!
Want to ensure that miracle drugs can no longer perform miracles?
Then do what some physicians and industrial livestock farmers have done for years: Overprescribe antibiotics to people, and use them cavalierly in farm animals to promote growth or prevent infections before they even occur.

Scientists fear the mosquito-borne virus, Chikungunya, which has infected tens of thousands of people in Papua New Guinea, could spread to Australia.
The virus, which originated in Africa, is similar to dengue and causes debilitating joint pain, rashes and fever.
Amid an outbreak of the vi... Read More
Researchers from Boston Medical Center (BMC) and Boston University School of Medicine (BUSM) have identified obesity as a possible risk factor for clostridium difficile infection (CDI). These findings, which appear online in Emerging Infectious Diseases, may contribute to improved clinical surve... Read More
Gone are the days when bacteria were thought to just grow and divide and not bother to converse with one another. That simple idea has produced mountains of data and most of what we know about bacterial physiology is based on this notion. It turns out, as we know now, that this is an oversimplif... Read More
Getting a flu shot cuts the risk of having a heart attack or stroke by more than 50% in people who have had a heart attack, a new study shows.
"We may have identified that the flu vaccine may also be a vaccine against heart attacks," says lead author Jacob Udell, a cardiologist at Women's Col... Read More
U.S. influenza activity remains low, but Los Angeles County confirmed its first death -- a woman with an underlying medical condition, an official says.
Dr. Jonathan E. Fielding, director of public health and health officer, says the woman resided in the San Fernando Valley and the particular... Read More
The gut bacteria in horses are being researched at the University of Pennsylvania, in a series of projects that scientists hope will ultimately benefit animal and human health.
Researchers at the university’s School of Veterinary Medicine are leading five pilot projects as part of the wider i... Read More
Bacteria, with their ability to grow, develop and sustain themselves in a variety of conditions, could be the miniature powerhouses that could drive us to a clean energy future.
Researchers at Arizona State University’s Biodesign Institute are studying certain bacteria’s ability to produce el... Read More
Scientists from Harvard and Yale came together to achieve what was once thought impossible: to fundamentally transform the identity and properties of an organism by re-coding its genome.
According to the study published this month in the journal Science, the scientists successfully developed ... Read More
New research shows giant pandas have a stronger immune system than previously known, because the panda immune system develops different antigens depending on where it lives.
This genetic diversity is a natural defense against extinction, because it means a single pathogen cannot wipe out the ... Read More
The immune system has the capacity to "remember" particular viruses and store those details in B memory cells that reside in the lungs to help ward off future infections. But a new study shows the flu virus takes advantage of this and uses the way the memory cells store its details to recognize ... Read More
Scouring the genomes and body-wide microbial communities of 93 people, researchers have discovered a link between the composition of the microbiome and genetic variation in innate immunity, phagocyte function, and other immune pathways. The research was presented by University of Minnesota popul... Read More
Forty million lab tests are done in B.C. annually. Each and every one is an opportunity for human error leading to patient harm.
In a bid to avert errors in collection, handling and analysis, a small team at the University of B.C. manufactures simulated specimens to send to labs across Canada... Read More
Making hydrogen easily and cheaply is a dream goal for clean, sustainable energy. Bacteria have been doing exactly that for billions of years, and now chemists at the University of California, Davis, and Stanford University are revealing how they do it, and perhaps opening ways to imitate them.

Some gut bacterial strains are specifically adapted to use sugars in our gut lining to aid colonisation, potentially giving them a major influence over our gut health.
We live in a symbiotic relationship with trillions of bacteria in our gut. They help us digest food, prime our immune system ... Read More
