The first human study using gene transfer to treat erectile dysfunction (ED) shows promising results and suggests the potential for using the technology to treat overactive bladder, irritable bowel syndrome and asthma, according to the researchers.

Findings from one of the largest HIV/AIDS therapy studies conducted to date show that a specific strategy of interrupting antiretroviral therapy more than doubles the risk of AIDS or death from any cause. Researchers affiliated with the Mailman School of Public Health and Harlem Hospital Hospital led a large multi-center international study, known as Strategies for Management of Anti-Retroviral Therapies, or SMART, comparing two treatment strategies for people with human immunodeficiency virus (HIV). Findings from the study, published in the November 30 New England Journal of Medicine, demonstrate the value of continuous antiretroviral therapy.

University of California, Berkeley, chemists have discovered a trick that anthrax bacteria use to make an end run around the body's defenses, but which may turn out to be their Achilles' heel.

CSIRO researchers have located the gene that controls the colour of apples – a discovery that may lead to bright new apple varieties.

P(acman) – a new method of introducing DNA into the genome of fruit flies or Drosophila – promises to transform the ability of scientists to study the structure and function of virtually all the fly’s genes, and the method may be applicable to other frequently studied organisms such as mice, said its Baylor College of Medicine developers in an article in the current issue of the journal Science.

In a new twist on the slogan “milk does a body good,” radiologists are testing use of the dairy staple as a contrast agent in gastrointestinal imaging exams—with excellent results. The researchers reported their findings today at the annual meeting of the Radiological Society of North America (RSNA).

Scientists at Wake Forest University Baptist Medical Center and colleagues at four other medical centers have launched a $10 million multi-year study to identify genes that may contribute to early atherosclerosis.

Researchers at Johns Hopkins have discovered what they believe is the "smoking gun" responsible for most tissue and organ damage after a period of blood oxygen loss followed by a sudden restoration of blood oxygen flow.
