On the continental margins, where the seafloor drops hundreds of meters below the water’s surface, low temperatures and high pressure lock methane inside ice crystals. Called methane hydrates, these crystals are a potential energy source, but they are also a potential source of global warming if... Read More
The armed guards at Mali's Bamako Senou International Airport had never seen a German shepherd before. The only dogs they were familiar with were the small, scrappy mixed breeds that are common in West Africa. So when Dana, a wolf-like purebred from California, stepped off a plane and into the a...

A probiotic that prevents obesity could be on the horizon.
Bacteria that produce a therapeutic compound in the gut inhibit weight gain, insulin resistance and other adverse effects of a high-fat diet in mice, Vanderbilt University investigators have discovered.
“Of course it’s hard to spec... Read More
Purdue University researchers have developed a laser sensor that can identify Salmonella bacteria grown from food samples about three times faster than conventional detection methods.
Known as BARDOT (pronounced bar-DOH'), the machine scans bacteria colonies and generates a distinct black and... Read More
Mould species of the genera Fusarium and Altenaria are considered the most important threats to Norwegian grain cereals because they produce toxins which can be a potential risk to food safety. F. avenaceum, the fungi most frequently isolated from Norwegian grain, produces enniatins which have b... Read More

Johns Hopkins researchers have found evidence in mice that a tuberculosis (TB) infection in the lungs triggers immune system signaling to the gut that temporarily decreases the diversity of bacteria in that part of the digestive tract.
The Johns Hopkins researchers showed that this decrease i... Read More
Activating a mother’s immune system during her pregnancy disrupts the development of neural cells in the brain of her offspring and damages the cells' ability to transmit signals and communicate with one another, researchers with the UC Davis Center for Neuroscience and Department of Neurology h...

The sad news, upsetting for the family of the 46-month-old girl, also dashed the hopes of clinicians who believe... Read More
Triclosan – a synthetic antibacterial widely used in personal care products – is fueling the development of resistant bacteria in streams and rivers. So reports a new paper in the journal Environmental Science and Technology, which is the first to document triclosan resistance in a natural envir... Read More
