Scientists have identified a small family of lab-made proteins that neutralize a broad range of influenza A viruses, including the H5N1 avian virus, the 1918 pandemic influenza virus and seasonal H1N1 flu viruses. These human monoclonal antibodies, identical infection-fighting proteins derived from the same cell lineage, also were found to protect mice from illness caused [...]

It is estimated that 4 million people world-wide are suffering from Parkinson’s, a complex disease that varies greatly among affected individuals. Understanding the brain chemistry that leads to the onset of Parkinson’s is vital if we are to develop methods for early MRI diagnosis and new treatments for this devastating disease.

Obese people who drink fructose-sweetened beverages with their meals have an increased rise of triglycerides following the meal, according to new research. This effect was especially pronounced in insulin-resistant subjects, worsening their already adverse metabolic profiles and potentially increasing their risk for heart disease and other metabolic disorders.

Scientists have piggybacked antibodies onto radioactive payloads to deliver doses of radiation that selectively target and destroy microbial and HIV-infected cells. The experimental treatment — called radioimmunotherapy, or RIT — holds promise for treating various infectious diseases, including HIV and cancers caused by viruses.

Scientists have followed up on an intriguing study showing that mice persistently infected with certain forms of herpes virus, which can establish lifelong latent infections, are resistant to infection with bacterial pathogens. Researchers are concerned with the implications of such research for the development of vaccines against herpesvirus infections.

Researchers have analyzed a “gold mine” of networking data from EverQuest II, a fantasy massive multiplayer online role-playing game, along with a survey of 7,000 players. Their findings include that many players underestimate the amount of time they spend playing the games, the number of players who say they are depressed is disproportionately high — [...]

DHEA is a natural circulating hormone and the body’s production of it decreases with age. Men take DHEA as an over-the-counter supplement because it has been suggested that DHEA can reverse aging or have anabolic effects since it can be metabolized in the body to androgens.
