A new study found no changes in opioid outcomes among the general population with the states’ passage of medical and recreational marijuana laws. However, the findings also show decreases in opioid outcomes after medical marijuana laws existed among people reporting cannabis use.

A groundbreaking study has identified a significant relationship between indoor temperatures and cognitive performance in older adults, shedding light on how climate change may pose an increased risk to cognitive health.

 

Conducted by scientists at the Hinda and Arthur Marcus Institute for Aging Research, the research arm of Hebrew SeniorLife, a nonprofit affiliate of Harvard Medical School, the study found that older adults reported the least difficulty maintaining attention when their home temperatures were within 68–75 ˚F (20–24 ˚C). Outside of this range, the likelihood of attention difficulties doubled with a 7 ˚F (4 ˚C) variation in either direction.

Due to the physical contact nature of their occupation, the elite athletes of the National Football League (NFL) often experience pain. However, an analysis of 2021 and 2022 data from the National Football League Prescription Drug Monitoring Program shows that team members in those two years were even less likely than both the general U.S. population and males of similar age living in the U.S., to have a prescription for an opioid pain medication.

It's long been known that different positions on the football field fit different body types. A study led by the University of Kansas has gone beyond knowing that linemen are bigger with more body mass than receivers and tested a team of college football starters, finding differences in strength, power, jumping ability and more. The findings could help improve strength training designed to optimize performance for different types of players, researchers argue.

Radiation-induced mutation is unlikely to have induced genetic differences between dog populations in Chornobyl City and the nearby Chornobyl Nuclear Power Plant.

Arizona is one of the fastest-growing states in the United States, but it is facing critical shortage of primary care physicians. Today, Arizona currently ranks 42^nd in primary care access and will need 1,941 primary care physicians by 2030 to meet growing demand, according to the Association of American Medical Colleges.

Radiation-induced mutation is unlikely to have induced genetic differences between dog populations in Chornobyl City and the nearby Chornobyl Nuclear Power Plant (NPP),   The study has implications for understanding the effects of environmental contamination on populations over time.
