Evidence in mice and human brain tissue reveals a mechanism that may explain the sex-based differences in Alzheimer's disease, including why females are more vulnerable. Researchers report that female brains show higher expression of an X-linked enzyme called ubiquitin-specific peptidase 11 (USP11) compared to males, resulting in greater accumulation of a protein called tau.

Obesity afflicts approximately 42 percent of the U.S. adult population and contributes to the onset of chronic diseases, including diabetes, cancer, and other conditions. While popular healthy diet mantras advise against midnight snacking, few studies have comprehensively investigated the simultaneous effects of late eating on the three main players in body weight regulation and thus obesity risk: regulation of calorie intake, the number of calories you burn, and molecular changes in fat tissue. A new study provides experimental evidence that late eating causes decreased energy expenditure, increased hunger, and changes in fat tissue that combined may increase obesity risk.

Despite decades of medical advances, children who develop the pediatric eye cancer retinoblastoma often lose their vision or an eye due to a lack of specific, targeted therapies and a poor molecular understanding of the cancer. Now researchers have discovered that a molecule -- estrogen-related receptor gamma, or ESRRG -- becomes hyperactive and promotes tumor cell survival in retinoblastoma. Blocking ESRRG, the team reported, kills retinoblastoma cells.
