Doctors have used gene therapy to upgrade the immune system of 12 patients with HIV to help shield them from the virus's onslaught. It raises the prospect of patients no longer needing to take daily medication to control their infection. The patients' white blood cells were taken out of the body... Read More
You'll need a strong stomach to walk into a new exhibit open at the Dublin Science Gallery: On display are cheeses cultured from the body bacteria of celebrities from the realms of science, food and art.
Eleven "cheese portraits" include a farmhouse cheese, a washed rind, a natural rind, a w... Read More
This episode: Non-pathogenic Clostridium difficile strains can protect hamsters against their disease-causing bacterial siblings!
(7 MB, 7.5 minutes)
When hamsters were colonized with toxin-free strains of C. difficile, they were better able to resist infection b... Read More
The death last week of a Florida man from an uncommon flesh-eating bacterium was the state's ninth so far this year.
The bacterium is in the same family as those that cause cholera.
Henry Konietzky, 59, of Palm Coast, Fla., died Sept. 23 after setting crab traps two days earlier in the riv... Read More
For cellphone whisperers, families that live near highways, airports or trains, music-loving commuters, and even individual cells, noise is an inescapable fact of life. In everyday human experience, the nuisance is often manageable. Soundproof barriers and noise-canceling headphones help scrub t... Read More
Virulent, drug-resistant forms of E. coli that have recently spread around the world emerged from a single strain of the bacteria, not many different strains, as has been widely believed.
The strain—which causes millions of urinary, kidney and bloodstream infections a year—could have a far gr... Read More
An international team of researchers has made important progress in understanding the distribution of the deadly amphibian chytrid pathogen. In some regions, the deadly impact of the pathogen appears to be hampered by small predators, naturally occurring in freshwater bodies. These micropredator... Read More
Your immune system influences the types of microorganisms that live on your skin and affect your risk for disease, according to a new study. A person's skin contains millions of beneficial and potentially disease-causing microbes. Previous research has shown that these microbes influence the imm... Read More
Could the microbes that inhabit our guts help explain that old idea of "gut feelings?" There's growing evidence that gut bacteria really might influence our minds.
"I'm always by profession a skeptic," says Dr. Emeran Mayer, a professor of medicine and psychiatry at the University of Californ... Read More
Infection during a newborn's first 7 days of life is associated with bacterial infection or colonization in the mother. Early-onset neonatal infection, defined as infection in the first 7 days of life, is associated with maternal infection and colonization, a systematic review and meta-analysis ... Read More
Babies who are exposed to both bacteria and allergens in the first year of life are less likely to develop asthma and allergies, a study finds.
It's the latest wrinkle in the hygiene hypothesis — the notion that exposure to bacteria trains the infant immune system to attack bad bugs and ignor... Read More
Teaming beneath Sweden's thawing permafrost is a previously undiscovered microbe known as methanongen (Candidatus Methanoflorens Stordalenmirensis). As its name suggests, the microbe does one thing really well: release methane into the atmosphere, presenting a feedback loop of gas production tha... Read More
Alberta health officials have confirmed an isolated, fatal case of H5N1 or avian influenza, federal Health Minister Rona Ambrose said Wednesday.
But officials repeatedly emphasized that there is no risk of transmission between humans.
The infected person, an Alberta resident who recently ... Read More
Some wild clones of social amoebas farm the bacteria they eat, but this is a losing strategy if nonfarming amoebas can steal the farmers’ crops. To make the strategy work, the farmers also carry bacteria that secrete chemicals that poison free riders. The work suggest farming is complex evolutio... Read More
New recommendation encourages physicians to prescribe _antibacterials_ instead of antibiotics for bacterial infections. This recommendation is based on compelling evidence that the word "antibiotic" confuses almost everyone, including some doctors. The confusion leads to strong patient demands... Read More
The nucleoside adenosine—a tiny chemical structure made up of a simple base linked to a sugar—is critical for the regulation of bodily functions ranging from blood flow to tissue repair to sleep. Now, researchers at Rutgers New Jersey Medical School show that adenosine is essential in promoti... Read More
In the early 1990s, Eshel Ben-Jacob, a biological physicist at Tel Aviv University, and his colleagues discovered two new species of bacteria—Paenibacillus dendritiformis and Paenibacillus vortex. Both strains of soil bacteria, the species live near the roots of plants.
Each bacterium is only... Read More
A 30,000-year-old giant virus has been revived from the frozen Siberian tundra, sparking concern that increased mining and oil drilling in rapidly warming northern latitudes could disturb dormant microbial life that could one day prove harmful to man.
The latest find, described online Monday ... Read More
The CHILD-INNOVAC European research programme, coordinated by Inserm, has enabled the development of an innovative vaccine that can be administered intranasally, to combat pertussis, which has shown a resurgence in developed countries in recent years. The research consortium, headed by Camille L... Read More
In his second expedition to South America, Darwin discovered many new species of animals and plants. The field observations obtained throughout this 5-year expedition provided the intellectual framework for the maturation of his ideas on evolution. It also introduced the world to a tiny (2-3 cm ...
