Center for BrainHealth® recently examined underlying brain networks in long-term cannabis users to identify patterns of brain connectivity when the users crave or have a desire to consume cannabis. While regional brain activation and static connectivity in response to cravings have been studied before, fluctuations in brain network connectivity had not yet been examined in cannabis users. The findings from this study will help support the development of better treatment strategies for cannabis dependence.
A University of California, Riverside, study that sought to determine barriers to health care among Spanish-speaking Latino farmworkers in rural communities has devised an innovative health care service delivery model that addresses many challenges these communities face: mobile health clinics that bring health care services to patients in their community spaces.
As many as 7% of moms-to-be use marijuana while pregnant, and that number is rising fast as more use it to quell morning sickness. But new research suggests such use could have a lasting impact on the fetal brain, influencing children's sleep for as much as a decade.
In a new study in rotifers (microscopic invertebrates), scientists tested the evolutionary fitness of older-mother offspring in several real and simulated environments, including laboratory culture, under threat of predation in the wild, or with reduced food supply. They confirmed that this effect of older maternal age, called maternal effect senescence, does reduce evolutionary fitness of the offspring in all environments, primarily through reduced fertility during their peak reproductive period. They also suggest an evolutionary mechanism for why this may occur.
New research from The University of Texas at Dallas suggests food deserts might be more prevalent in the U.S. than the numbers reported in government estimates. In a feasibility study published in the journal Frontiers in Public Health, scholars found that the methods used by the U.S. Department of Agriculture (USDA) to identify areas with low access to healthy food are often outdated and narrow in scope.
Incarceration and police discrimination may contribute to HIV, depression and anxiety among Black gay, bisexual and other sexual minority men, according to a Rutgers led study.
Getting married early in life may increase the risk of problematic drinking behavior among people who are genetically predisposed to drink more, according to a forthcoming study led by researchers at Virginia Commonwealth University.
Researchers at Global TIES for Children, an international research center based at NYU Abu Dhabi and NYU New York, examined a variety of post-migration risks faced by Syrian refugee children enrolled in Lebanese public schools and found that students being older than expected for the grade in which they were placed was most consistently and strongly associated with developmental and learning difficulties.
A recently published study shows that families that receive Supplemental Nutrition Assistance Program (SNAP) benefits later in the month have fewer ER visits, likely because they can afford to feed their families at the end of the calendar month when other resources run low.
New research reported in the journal Psychological Science finds that priming people to think about accuracy could make them more discerning in what they subsequently share on social media.
