A major UC San Diego study tracking more than 11,000 children found that teens who use cannabis show slower development in memory, attention and thinking skills compared to non-users. Researchers said adolescence is a critical period for brain development, and even small cognitive differences can build over time. The findings come as cannabis use remains common among teenagers nationwide. Experts hope the long-term study will help families better understand the potential risks of marijuana use during adolescence.

Researchers at the Salk Institute for Biological Studies found that GLP-1 drugs like Ozempic and Zepbound may reprogram pancreatic cells, improving insulin production and resilience beyond weight loss. Used by over 30 million Americans, the drugs trigger genetic changes through a protein called Med14. Scientists say long-term use could produce lasting metabolic benefits, though research is ongoing to fully understand their broader effects.

Losing an hour of sleep during the spring Daylight Saving Time shift may have serious health consequences, including increased heart attacks, strokes, and traffic accidents. Researchers like Dr. Emily Manoogian at the Salk Institute study how circadian rhythms regulate sleep and bodily functions. Even small disruptions can misalign the body’s internal clock, which depends on light cues. Studies show a spike in motor vehicle crashes after the time change, and many scientists advocate for permanent standard time to better align with human biology.
