First-time parents are only somewhat satisfied with their sex lives according to Penn State health researchers who checked in with parents regularly after their baby was born. And one factor that appears to be reducing their sexual satisfaction is mothers' stress as a new parent.
A survey of more than 216,000 adolescents from all 50 states indicates the number of teens with marijuana-related problems is declining. Similarly, the rates of marijuana use by young people are falling despite the fact more US states are legalizing or decriminalizing marijuana use and the number of adults using the drug has increased.
A long line of research links poverty and depression. Now a study by Duke University scientists unveils some of the biology of depression in high-risk adolescents whose families are socioeconomically disadvantaged. Published in Molecular Psychiatry, the study combines epigenetics, brain imaging and behavioral data over three years. The results are part of a growing body of work that may lead to biological predictors that could guide individualized strategies for preventing depression.

New research led by SUNY Downstate Medical Center shows that mice devoid of PKMzeta, a molecule previously identified by SUNY Downstate scientists as essential to memory formation and storage, recruit a closely related molecule, PKCiota/lambda, to make up for the missing PKMzeta.
A team of scientists has identified the existence of a back-up plan for memory storage, which comes into play when the molecular mechanism of primary long-term memory storage fails.
A study from the Department of Population Health at NYULMC and New York University's Center for Drug Use and HIV Research, led by Scheidell, is the first to examine the association between borderline personality disorder (BPD) and the risk for HIV and other STIs in an adult male criminal justice population.
A small brain structure plays a central role in the many decisions like this we make each day. But it has not been clear how a limited number of neurons in this small part of the brain can support an unlimited number of choices. Now, studying how macaque monkeys choose between juice drinks, researchers at Washington University School of Medicine in St. Louis have found that the neurons can re-map to make different decisions when circumstances change.
With opioid addiction and prescription drug abuse considered one of the biggest public health threats of our time in the US, many are asking why so many Americans are struggling with addiction to illegal drugs and prescription medications.
