AI systems are increasingly browsing the web, executing code, managing files, and sending messages without step-by-step human approval, raising new risks in the process, according to a new TechBrief from the Association for Computing Machinery’s Technology Policy Council (TPC) on the rise of agentic AI.

Remote monitoring isn’t a panacea for reducing readmissions across all conditions — and for some patients, clinicians should proceed with caution, clinical trial results published today in JAMA Network Open suggest.

A new Annenberg survey finds that Americans are divided on support for public water fluoridation, with MAHA supporters notably more skeptical. The American Dental Association is trusted by more than 2-1 over HHS Secretary Robert F. Kennedy Jr. on the health effects of fluoride in water.

Global rice production nearly doubled between the 1960s and the 2010s, despite the negative impacts of climate change, according to a new study from the University of Illinois Urbana-Champaign. The study found that management decisions — including expanded irrigation and increased nutrient inputs — played a central role in sustaining rice production and offsetting climate-related losses. The results of the study suggest that future food security will depend not only on environmental conditions, but also on how rice production systems are managed and adapted to changing conditions.
