Online intervention shows promise in HIV prevention

More than 67 percent of all new HIV infections in the United States in 2016 occurred as a result of transmission through sexual contact among men who have sex with men (MSM). Young gay, bisexual, and other men who have sex with men (YGBMSM) are particularly at risk, accounting for 81 percent of new HIV infections among people ages 13 to 24. YGBMSM's risks for HIV coincide with developmental milestones as they transition into adulthood, including their exploration and pursuit of sexual and romantic relationships. At present, many of those explorations take place over the Internet, as evidenced by the increasing use and popularity of social networking and dating sites.

An existing drug may have therapeutic potential in mitochondrial disease

New preclinical findings from extensive cell and animal studies suggest that a drug already used for a rare kidney disease could benefit patients with some mitochondrial disorders—complex conditions with severe energy deficiency for which no proven effective treatments exist. Future clinical research is needed to explore whether the drug, cysteamine bitartrate, will meaningfully benefit patients.

Electrically-heated silicate glass appears to defy Joule's first law

Characterizing and predicting how electrically-heated silicate glass behaves is important because it is used in a variety of devices that drive technical innovations. Silicate glass is used in display screens. Glass fibers power the internet. Nanoscale glass devices are being deployed to provide breakthrough medical treatments such as targeted drug-delivery and re-growing tissue.

Review suggests a reciprocal relationship between obesity and self-control

In a review published February 26 in the journal Trends in Cognitive Sciences, researchers explore the age-old chicken-or-the-egg conundrum but this time looking at whether obesity reduces self-control or if reduced self-control leads to obesity. The authors argue that the short answer is both, and it is largely due to activity in the prefrontal cortex, which is not only affected by our dietary choices, but can also influence it.
