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.
Researchers from the University of Rochester suggest that children raised in poverty may have been mistakenly labeled as 'maladapted' for what appears to be a lack of self-control. The new study finds that what looks like selfishness may actually be beneficial behavior that's based on a child's environmental context -- that is to say, from being raised in a resource-poor environment.
Researchers report an association between smoking during pregnancy and increased risk for schizophrenia in children. The paper evaluated nearly 1,000 cases of schizophrenia and matched controls among offspring born in Finland from 1983-1998. Results showed that a higher maternal nicotine level in the mother's blood was associated with an increased risk of schizophrenia among their offspring. The study provides the most definitive evidence to date that smoking during pregnancy is associated with schizophrenia.
UCLA neuroscientists have identified in mice how the brain links different memories over time. While aging weakens these connections, the team devised a way for the middle-aged brain to reconnect separate memories.The findings suggest a possible intervention for people suffering from age-related memory problems.
Certain life experiences can worsen the negative effects of dropping out of school, but some interventions and treatments can help change the odds for dropouts, a new study finds.
New research demonstrates the effectiveness of ketamine to treat depression in a mouse model of the disease. The brings together two hypotheses: 1) that depression results from deficits in GABA signaling and 2) that depression results from deficits in glutamate signaling. It shows that the depression-like behavior in the research mice results from the reduction of both GABA and glutamate, and importantly, that both can be restored with a single dose of ketamine.
Non-Hispanic blacks are almost twice as likely as non-Hispanic whites to be diagnosed with schizophrenia, but they're significantly less likely to receive medication for treatment, according to researchers.
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.
'How does it 'feel' to interact behaviorally with a machine?' To answer that, scientists created a virtual partner that can elicit emotional responses from its human partner while the pair engages in behavioral coordination in real-time. The virtual partner's behavior is governed by mathematical models of human-to-human interactions in a way that enables humans to interact with the mathematical description of their social selves.
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.
