While the incidence of disease from HIV and hepatitis is increasing in the United States, little is known about their prevalence in patients undergoing surgery. Now, researchers have shown that nearly 40 percent of surgeries at The Johns Hopkins Hospital occur in patients who tested positive for a bloodborne germ.

To understand the complex processes in the human brain that lead to addiction, some researchers at UCSD have turned to bees.

The prevention and treatment of malaria has made progress since 2000, but an annual death toll of 1 million people presents challenges as the mosquito-borne parasitic disease makes a comeback, the first joint malaria report from the UN World Health Organization (WHO) and UN Children's Fund (UNICEF) says.

The report on the disease that claims three times as many African children's lives as HIV/AIDS was launched today at events in New York, Geneva and Cairo.

In their extraordinary annual migration from North America to Mexico, monarch butterflies are known to use the angle of polarized sunlight as a celestial guide to help them keep to a straight and true path southward. But details of their navigational machinery have remained a mystery.

Men who fought in World War II, the Korean War, and the Vietnam War are more likely to be heavy drinkers, heavy smokers and obese than men who are non-combat veterans or non-veterans, according to a study presented at the American Heart Association's 45th annual Conference of Cardiovascular Disease, Epidemiology and Prevention.

Scientific theory holds that Huntington's disease (HD) is caused by a mutant protein that arises within brain cells and kills them, triggering the genetic neurological disorder. Now a new UCLA Neuropsychiatric Institute study reveals the first strong evidence that the mutant protein also elicits toxic interactions from neighboring cells to provoke the fatal brain disorder. The May 5 edition of Neuron reports the findings.

Researchers at the Johns Hopkins Bloomberg School of Public Health have developed a new method for identifying specific proteins in whole cell extracts of microorganisms using traditional peptide mass fingerprinting (PMF). The key to the new method, according to the researchers, is a "shortcut" for preparing samples that makes PMF faster and more economical. By reducing the cost of protein identification, they believe PMF can become an economical tool for monitoring and evaluating the effectiveness of microorganisms used in environmental cleanup. The researchers used a dioxin-eating organism to demonstrate the capabilities of their methodology, which they described in an article published in the May 2005 edition of Applied and Environmental Microbiology.
