Anti-HIV drug simulation offers 'realistic' tool to predict drug resistance and viral mutation
Pooling data from thousands of tests of the antiviral activity of more than 20 commonly used anti-HIV drugs, AIDS experts at Johns Hopkins and Harvard universities have developed what they say is the first accurate computer simulation to explain drug effects.

Study sheds light on lung cancers that are undetected by radiograph
New research has revealed why some lung cancers are undetected by radiograph and helped to identify the type of people who may be at risk of this form of the disease.

Heavy drinking rewires brain, increasing susceptibility to anxiety problems
After chronic alcohol exposure, mice are unable to control a learned fear response, shedding light on the link between alcoholism and anxiety problems like post-traumatic stress disorder.
