In utero exposure to two liquid ingredients in e-cigarettes – minus the nicotine that drives addiction – can alter skull shape during fetal development, a new study in mice has found.   

 Many people might be aware of an ongoing opioid epidemic, with thousands of people dying every year from overdoses. But many who are misusing opioids are also using—and dying from—stimulant drugs as well, according to a study published July 2 in the open access journal PLOS Mental Health by Yutong Li from the University of Alberta, Canada, and colleagues.

Food insecurity is not only linked with, but directly causes symptoms of anxiety and depression, according to research published in the open access journal PLOS Mental Health. Melissa Bateson of Newcastle University, UK, and colleagues at École Normale Supérieure, Northumbria University and York University, collected monthly data from adults in the UK and France and found that changes in food insecurity one month resulted in changes in symptoms of anxiety and depression the next. The authors therefore propose that interventions to reduce food insecurity would have immediate positive impacts on mental health.
