A poll of older adults looks for signs of addiction to ultraprocessed foods and drinks, and finds especially high rates among those in their 50s and early 60s who were children and teens during the 1980s when the nation's food environment changed.

Research published by Duke University researchers has found a strong link between higher stress in children and adverse health conditions for them later in life. Appearing in the journal “Proceedings of the National Academy of Sciences,” the study used measurable metrics of health over time to create a more quantitative view of how stress early in life affects health.

Researchers at the German Center for Infection Research (DZIF) at Heidelberg University Hospital have decoded a previously unknown mechanism by which HIV-1 selects its integration targets in the human genome. A research team led by DZIF scientist Dr. Marina Lusic identified RNA:DNA hybrids (R-loops) as molecular signposts for the virus. These findings reveal a key vulnerability in the life cycle of HIV-1. The results, published in the renowned journal Nature Microbiology, provide new therapeutic approaches for specifically controlling HIV reservoirs in the body. This has been one of the biggest obstacles to long-term or curative HIV therapies.

Historically, Americans have obtained the overdose reversal drug naloxone through prescription or free distribution programs. But in September 2023, naloxone became available over the counter with the hope it would increase access to the overdose reversal treatment. A new study finds that sales of naloxone increased after it was made available to the public without a prescription, but then dipped quickly in the period following debut of over-the-counter sales.
