In a pioneering effort, researchers have demonstrated the value of a new strategy for identifying relatively rare genetic variants that may cause or contribute to disease.
Three young adults who received gene therapy for a blinding eye condition remained healthy and maintained visual gains one year later, researchers reported. One patient also noticed a visual improvement that helped her perform daily tasks.
Researchers have created the first comprehensive picture of how the entire HIV genome bends and folds. The finding may point to new options for treating or blocking HIV and other viral infections.

Imitation is the sincerest from of flattery, the old saying goes. It may also help to promote social bonds. A new study reports that monkeys prefer humans who imitate them over those who don't. Mimicry, the researchers suggest, may be an ancient behavior that sets the stage for primates to form social groups.
Scientists have discovered why people who develop genital herpes sores are at higher risk of contracting HIV despite successful treatment of the lesions. The new insight may lead to better strategies for HIV prevention.
Sprouting. Branching. Pruning. Neuroscientists have borrowed heavily from botanists to describe the way neurons grow. A new study suggests the analogies may be more than superficial. Neurons and plant root cells may grow using a similar mechanism. The research sheds light on a group of inherited neurological disorders called hereditary spastic paraplegias (HSP).

Near-normal control of glucose beginning as soon as possible after diagnosis greatly improves the long-term prognosis of type 1 diabetes, a new study found.
Scientists have identified several genetic variants associated with blood pressure in African-Americans. The results of this new genome-wide study offer potential clues to treating and preventing chronic high blood pressure, or hypertension.
Scientists have identified 2 proteins that regulate the production of antibodies that fight disease-causing viruses and other pathogens. The findings have potential applications both for vaccine development and for treating autoimmune diseases, in which the body produces antibodies that attack itself.
