Adolescents often sleep less than recommended and have substantially different sleep patterns between weekdays and weekends. Their mismatch in sleep timing between school and free days, known as social jet lag, has been linked to adverse physical, cognitive, and mental health outcomes, though the mechanisms have been poorly understood. In a first of its kind study, published in the journal SLEEP, researchers from Boston Children’s Hospital and Johns Hopkins All Children’s Hospital have found that social jetlag has widespread negative effects on fundamental aspects of the developing brain's function and structure, impacting areas of the brain that support processes such as emotional regulation and social function.

People might attribute midnight bouts of chest pain or waves of nausea to food poisoning, stress or a stubborn case of indigestion, but Rutgers Health researchers suggest that knowing your family’s surgical past could pinpoint another cause: gallstone disease.

Their study, published in the Journal of Surgical Research, found that patients who were aware of family members’ past gallbladder surgery were more likely to seek help early – and were less likely to end up in the operating room for high-risk, emergency gallbladder removal.

Twenty percent of people over 50 who use cannabis products reported that at least once in the past year, they had driven within two hours of using the drug. That means they likely got on the road while the THC in cannabis still impaired their reaction times, attention and other abilities that are important to driving safely. Men, those who use cannabis daily and those who use it for mental health reasons were mostly likely to report driving soon after using.
