Researchers at the National Institutes of Health (NIH) have developed eye drops that extend vision in animal models of a group of inherited diseases that lead to progressive vision loss in humans, known as retinitis pigmentosa. 

A drug-resistant type of bacteria that has adapted to health care settings evolved in the past several years to weaponize an antimicrobial genetic tool, eliminating its cousins and replacing them as the dominate strain. University of Pittsburgh School of Medicine scientists made the discovery when combing through local hospital data – and then confirmed that it was a global phenomenon.

Adolescence is a critical time for developing social skills and youth often navigate difficult peer experiences. Parents can help their children by giving advice on how to deal with challenges, but it matters whether youth want support or not. A new study from the University of Illinois Urbana-Champaign looks at the impact of parental advice and youth support seeking in African American families.

An experimental drug appears to reduce the risk of Alzheimer’s-related dementia in people destined to develop the disease in their 30s, 40s or 50s, according to the results of a study led by the Knight Family Dominantly Inherited Alzheimer Network-Trials Unit (DIAN-TU), which is based at Washington University School of Medicine in St. Louis. The findings suggest – for the first time in a clinical trial – that early treatment to remove amyloid plaques from the brain many years before symptoms arise can delay the onset of Alzheimer’s dementia.
