From Geneva, the joint UN programme on HIV/AIDS is reporting that it overestimated the number of people infected with HIV. The agency estimates that 33 million people worldwide are infected, down more than 16% from an estimate made last year. New data also revealed that the number of new infections per year have been dropping since the late 90s.
From Connecticut, researchers at Yale University have found that infants as young as six months can distinguish friends from foes. The finding is the result of a study on babies' reactions to an animation where a climber was either helped or hindered while scaling a hill. The result suggests that the ability to make moral judgments is evolved, rather than learned behavior.
And finally from Chicago, doctors at the Rush University Medical Center saved an 18-year old woman's life when they removed a 10-pound hairball from her stomach. The woman, who had been experiencing gastrointestinal pain and severe weight loss, admitted that she had been eating her own hair for five years. After surgical removal of the hairball and psychiatric treatment, the woman made a full recovery.
For Insidermedicine in 60, I'm Dr. Susan Sharma.
