Bacteria responsible for a lethal form of food poisoning may escape the immune system by hiding out in the gall bladder of seemingly healthy people. The finding by researchers at Stanford University School of Medicine suggests that an unwitting food worker could transmit the bacteria to others by contaminating food products.
The bacteria, Listeria monocytogenes, can cause severe illness or death in people with weakened immune systems and may cause miscarriage in pregnant women. "Twenty to 40 percent of people with listeriosis" - the disease caused by Listeria infection - "die even after antibiotic treatment," said Jonathan Hardy, PhD, the studys first author and a research associate in the Department of Pediatrics. The research is published in the Feb. 6 issue of Science.
Listeriosis causes about 500 U.S. deaths annually; pregnant women are about 20 times more likely than other healthy adults to become infected. Unlike many bacteria, Listeria is perfectly happy growing at refrigerator-like temperatures and can survive for long periods outside of its many animal hosts. It is most commonly found in foods such as soft cheeses and deli meats - products pregnant women are often told to avoid.

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
