A study of HIV-positive black and Latino men who have sex with men finds the use of methamphetamine combined with intimate partner violence boosted the activity of genes that regulate the body's inflammatory and antiviral functions. The combination may lead to exhaustion of the immune system in people living with HIV, increasing the risk for developing chronic diseases such as cardiovascular disease and other disorders.

Chronic wounds are deep and difficult to repair. Often, the top of the injury heals before the bottom, so the wound collapses in on itself. Over time, this can result in scar tissue and reduced skin function.

Air trapped with ice below glacier surfaces becomes a compressed bubble-ice mixture that builds pressure during the long passage to the glacier terminus. The glacier ice holds ancient bubbles of air that can be up to 20 atmospheres of pressure and generate detectable sounds when they are released as the ice melts.

Food texture can make the difference between passing on a plate and love at first bite. To date, most studies on food texture center on relating a food's overall composition to its mechanical properties. Our understanding of how microscopic structure and changes in the shape of food affect food texture, however, remains underdeveloped.
