Researchers: Emphasize personal health benefits of COVID-19 vaccination

A recent study by University of Wyoming economists suggests that public health messages focusing on the personal health benefits of COVID-19 vaccines are most effective in increasing vaccination intentions. The researchers found that such messages increased intended vaccinations by 16 percentage points, significantly more than other ty...

Model can predict how drug interactions influence antibiotic resistance

A new model using simple changes in microbe growth curves can predict how antibiotic resistance evolves in response to different treatment combinations, doses and sequences. The model helps explain counterintuitive behavior observed in past experiments, such as slowed evolution when combining two antibiotics.

Wolf-Branigin receives funding for child welfare stipend program

Professor Michael E. Wolf-Braningin received awards totaling $267,675 from the US Department of Health and Human Services to support student stipends for child welfare careers. The awards are part of a partnership between George Mason University's social work department and the Virginia Department of Social Services.

Closeness with dads may play special role in how kids weather adolescence

New research at Penn State found that close, supportive relationships with parents, especially dads, can help stave off certain adjustment problems during adolescence. The study showed that father-adolescent intimacy was associated with fewer depressive symptoms and weight concerns across most of adolescence.

Good toothbrushing habits in children linked to mother's wellbeing

A study published in Community Dentistry And Oral Epidemiology found that children with mothers suffering from postpartum depression or bonding disorders brush their teeth less often. In contrast, mothers showing strong affection towards their children increase the frequency of their child's toothbrushing.

Inequity in the air of India

A recent study by IIASA researchers found that higher income groups in India contribute more to ambient air pollution, resulting in higher mortality rates among lower income groups. The study suggests that policies targeting specific emission sources could help distribute the load more fairly.
