German researchers have isolated a strain of Salmonella in pork that is closely related to the bacteria commonly found in chickens and linked to human food-borne illness. They report their findings in the July 2010 issue of the journal Applied and Environmental Microbiology.
First emerging ov... Read More
Researchers from the U.S. and abroad used bacteria inherent to the human vaginal tract to develop a live, topical microbicide that may induce production of HIV-1 protein inhibitors and ultimately prevent transmission of the virus. They detail their findings in the July 2010 issue of the journal ... Read More
Patients with chronic gum disease who quit smoking in addition to undergoing nonsurgical therapy not only demonstrated a lower abundance of harmful oral pathogens, but also an increase in health-associated bacteria. The researchers from The Ohio State University, Columbus Ohio, and Newcastle Un... Read More
Raw milk enthusiasts are going to keep drinking their milk pretty much straight from the cow, it seems. Even in states like Maryland and Alaska, where the pure stuff has been driven underground as an unintended effect of legislation.
The popularity of raw milk is fueled by consumers' concerns... Read More
Mothers who drank milk with a probiotic supplement during and after pregnancy were able to cut the incidence of eczema in their children by almost half, a new study published in the British Journal of Dermatology has shown.
The randomized, double-blind study, conducted by researchers at the N... Read More
Antibiotic treatment during the liver stage of malaria generates strong protective immunity
If mice are administered an antibiotic for three days and are simultaneously infected with malaria, no parasites appear in the blood and life-threatening disease is averted. In addition, the animals tr... Read More
Sometimes a spoonful of sugar helps the medicine go down; or in this case, the vaccine. A new study released by mBio shows that combining β-(1-3)-D-glucans (long chains of the sugar glucose) with an antigen creates a potent vaccine platform that could eventually be put to clinical use.
An ... Read More
The variety of bacteria in the digestive tract is strongly linked to whether a child will develop type 1 diabetes, according to a new study.
The connection could give doctors an early test for the condition and lead to new treatment for the disease.
There appears to be little or no genetic... Read More
In a potential breakthrough in the prevention of AIDS, researchers are reporting today that a vaginal gel containing an existing AIDS drug can cut in half a woman's chances of getting HIV from an infected partner.
The women involved in the study used it only 60 percent of the time, and it was... Read More
We think of ourselves as individuals — perhaps, in philosophical moments, as the merger of body and soul. Most of us are barely aware of the estimated 10 trillion individual cells that make up the human body or of the 100 trillion or more bacteria that live collaboratively and benignly within an...

The first before-and-after view of an amphibian die-off has just been published by scientists working at the Smithsonian Tropical Research Institute in Panama.
Like a wave, the fungal disease that wipes out frogs—chytridiomycosis—advances through the Central America highlands at a rate of abo... Read More
Biologists at the California Institute of Technology (Caltech) have demonstrated a connection between multiple sclerosis (MS)—an autoimmune disorder that affects the brain and spinal cord—and gut bacteria. Read More
Researchers at Duke University Medical Center are using computers to identify how one strain of dangerous bacteria might mutate in the same way a champion chess player tries to anticipate an opponent's strategies. Read More
The battle to eliminate polio, which has been more than 99 percent successful and has hovered on the verge of victory for a decade, has sustained new setbacks.
There has been an outbreak of more than 300 cases in Tajikistan this year. (Tajikistan is just north of Afghanistan, and fighting on... Read More
Biofuel producer Solazyme delivered 1,500 gallons of its algae-based jet fuel to the U.S. Navy’s testing and certification program today, helping the military reach its goal of switching half of its fleet to clean fuel by 2020. The Navy will use the fuel to power jets.
Solazyme produces fuel ... Read More
A new vaccine-delivery patch based on hundreds of microscopic needles that dissolve into the skin could allow persons without medical training to painlessly administer vaccines – while providing improved immunization against diseases such as influenza. Read More
A new way of surveying microbes for the metals they contain reveals that biologists have been relying on the equivalent of a 15th century map of the world. Read More
Cool video of a bacteria-powered machine; 20-micrometer device that is powered by bacteria moving around in a narrow groove etched out in silicon (the green line). Read More
Revealing the science behind the homespun advice, a team of researchers at Worcester Polytechnic Institute (WPI) has identified and measured the molecular forces that enable cranberry juice to fight off urinary tract infections in people.
The data is reported in a paper published in the journ... Read More
Scientists in the US who developed a skin patch that uses hundreds of microscopic dissolvable needles to deliver vaccine into the body have shown it works on animals, perhaps even better than the traditional injection method; they envisage that one day this approach could reduce the cost and adm...
