A Yale School of Medicine study reveals that the high prevalence of the hepatitis C virus (HCV) among injection drug users may be partly due to the resilience of the virus in certain types of syringes. The study, which could open new avenues in preventing the spread of HCV, will be the focus of ... Read More
A common treatment for herpes can delay the need for HIV drugs in people with both infections, say US researchers. A study of 3,300 patients in Africa found aciclovir reduced the risk of HIV progression by 16%, The Lancet reports.
Although a "modest" effect, the researchers said the cheap tr... Read More
A negative rapid flu test did not necessarily mean that the patient did not have the 2009 H1N1 influenza, said experts at Baylor College of Medicine and Texas Children's Hospital in a report that appears online today in the journal Pediatrics.
"The test was specific. That means that if it was... Read More
Each week CDC analyzes information about influenza disease activity in the United States and publishes findings of key flu indicators in a report called FluView. During the week of January 31 – February 6, 2010, most key flu indicators remained about the same as during the previous week. Below i... Read More
A set of proteins found in our intestines can recognize and kill bacteria that have human blood type molecules on their surfaces, scientists at Emory University School of Medicine have discovered.
The results were published online Feb. 14 and are scheduled to appear in the journal Nature Medi... Read More
A strange new natural contender in aiding in the fight against biological weapons has stepped forward, with researchers learning that the fruit of mushrooms can be used in cleaning up following a biological attack.

Hospital workers often have to wash their hands dozens of times a day — and may need a minute or more to do the process right, by scrubbing with soap and water. But new devices could reduce the task to just four seconds, cleaning even hard-to-reach areas under fingernails.
Instead of scrubbi... Read More
Scientists have pinpointed specific mutations that allow a common plant virus to infect new species, according to research published in the March issue of the Journal of General Virology. Understanding the genetics of the key interactions between viruses and hosts could provide insight to how so... Read More
When it comes to periodontal disease, veterinarians are in a position to play a stronger role in preventing the most common disorder affecting cats and dogs worldwide, according to Banfield’s Applied Research and Knowledge (BARK) team. New findings show that 68 percent of cats and 78 percent of ... Read More
Of all science’s model organisms, none is as weird as Dictyostelium discoideum, a single-celled amoeba better known as slime mold. When they run out of food, millions coalesce into a single, slug-like creature that wanders in search of nutrients, then forms a mushroom-like stalk, scatters as spo... Read More
In a new study, Dartmouth researchers describe the structure of a protein called ToxT that controls the virulent nature of Vibrio cholerae, the bacteria that causes cholera. Buried within ToxT, the researchers were surprised to find a fatty acid that appears to inhibit ToxT, which prevents the b... Read More
La Jolla Institute scientists have proved a hypothesis that said antibodies contribute to severe dengue virus-induced disease.
The findings of the La Jolla Institute for Allergy & Immunology have major implications for efforts to develop a first-ever vaccine against the dangerous infectious d... Read More
The H1N1 virus, also known as swine flu, may have killed as many as 17,000 Americans, according to new estimates by the Centers for Disease Control and Prevention (CDC) in Atlanta.

At least 1,500 people in New York, most of them Orthodox Jews, have contracted mumps during a seven-month outbreak that began last summer in a boys camp in the Catskill Mountains, the Centers for Disease Control and Prevention reported Thursday in its Morbidity and Mortality Weekly Report. Almos... Read More
Finding a biological mechanism much like an online social network, scientists have identified the bacterial protein VpsT as the master regulator in Vibrio, the cause of cholera and other enteric diseases. This discovery, now published in the journal Science, provides a major tool to combat enter... Read More
Some turn to prayer. Others turn to state-of-the-art medicine. Lindsey Vonn turned to the power of fromage.
The Olympic favorite has been wrapping her injured shin in an Austrian cheese -- topfen -- to reduce inflammation.

When NASA's Viking landers touched down on Mars, they were looking for signs of life. Instead, all their cameras showed was a dry, dusty - and entirely barren - landscape.
Or so it seemed. But what the 1976 Viking mission, and every subsequent one, saw was a scene littered with rocks coated w... Read More
