Baltimore -- U.S. researchers say they've discovered a way to turn off the immune system's allergic reaction to food proteins in mice, which could have human applications.
The findings by scientists at the Johns Hopkins University School of Medicine provide hope the human body could be trained to tolerate allergies to foods like peanuts and milk suffered by millions, a university release said.
Researchers found one kind of immune cell in the gastrointestinal tract, considered the first line of defense for a body's immune system, expresses a special receptor that appears on the cell's surface and binds to specific sugars.

Sacramento -- An art experiment suggesting McDonald's food doesn't decay has raised eyebrows -- and raised questions about just what's in those Happy Meals, observers say.
A New York photographer left a McDonald's hamburger Happy Meal, complete with a small side order of french fries, sitting on a shelf in her home for more than 18 weeks. Every three days, Sally Davies took a photo of the food.
By day 137, the food looked pretty much the same, KTXL-TV, Sacramento, reported.
Some were quick to assume McDonald's is using preservatives to create the appearance of "fresh" food.
But scientists say preservatives aren't the main reason why the Golden Arches' food won't break down -- it's fat.

Moscow -- Russian authorities say they've declared a state of emergency because of an outbreak of anthrax in the country's southern Krasnodar Territory.
Anthrax was detected in cows at a dairy farm and authorities reported at least two employees had contracted the potentially fatal disease, RIA Novosti reported.
At least 30 farm employees working around the sick animals were placed under medical supervision but their test results were negative.
The farm was placed under quarantine and veterinarians were checking to see if privately kept cows in the area contracted the infection.

Paris -- Doctors in the south of France have been put on alert after the second case of mosquito-borne chikungunya virus was detected in the region, authorities said.
Two 12-year-old girls in the town of Frejus have now caught the virus and both cases were classified "native," meaning neither victim had traveled to the parts of eastern Africa, southeast Asia or the Indian subcontinent where the virus is widespread, Radio France Internationale reported.
The virus is carried by the tiger mosquito, which has been moving north in recent years, health officials say.
The tiger mosquito also carries dengue fever, and two cases were detected in the Riviera region for the first time earlier this month, they said.

Baltimore -- U.S. researchers say they've developed tiny tools that could be introduced into the human body for medical procedures and drug delivery.
The millimeter-sized metal tools that can change shape on command, clamping shut or popping open in response to specific chemical cues, may someday be used to biopsy a liver, open a clogged artery or deliver drugs to a specific target, ScienceNews.org reported Friday.
David Gracias and a team at Johns Hopkins University in Baltimore have created devices that can respond to chemicals in the right time and place, yet still be friendly inside the body.

London -- A genetic variant that protects against diseases such as tuberculosis is more prevalent in populations with long histories of city living, scientists say.
University College London researchers have found that in areas with a long history of urban settlements, today's inhabitants are more likely to possess the genetic variant that provides resistance to infection, a university release said.
In ancient cities, poor sanitation and high population densities would have provided an ideal breeding ground for the spread of disease.
Natural selection should mean humans would have developed resistance to disease in longstanding urbanized populations over time.

Kingston- Impulsive behavior is marked by specific changes in the brain, Canadian researchers say, findings that could help diagnose and treat several disorders.
Scientists at Queen's University in Ontario have pinpointed the area of the brain controlling impulsive behavior and the mechanisms that affect how impulsive behavior is learned, a university release says.
The research could have a significant impact on the diagnosis and treatment of several disorders and addictions, including ADHD and alcoholism, researchers say.
