Here's some good news if you are female: Research published online in The FASEB Journal, shows that in mice, what is eaten during adolescence or childhood development may alter long-term behavior and learning, and can even 'rescue' females from the negative effects on behavior resulting from a poor maternal diet during pregnancy.
Tiny nanostraws that sample the contents of a cell without causing damage may improve our ability to understand cellular processes and lead to safer medical treatments.
Memories are formed at structures in the brain known as dendritic spines, which communicate with other brain cells through 'synapses.' Researchers at SUNY Downstate Medical Center recently discovered that an inhibitory brain receptor triggers synaptic pruning in adolescence. Now, a new article by the SUNY Downstate researchers shows that drugs that selectively target these receptors, when administered during adolescence, can alter synapse number, with possible implications for the treatment of autism and schizophrenia.
Adolescents with posttraumatic stress disorder (PTSD) symptoms are more likely to misidentify sad and angry faces as fearful, while teens with symptoms of conduct disorder tend to interpret sad faces as angry, finds a study by NYU's Steinhardt School.
The study, led by autistic Portland State researcher Dora Raymaker, aims to determine what helps autistic people do well professionally by interviewing 95 autistic people and those who work with them. This study is both a personal and academic interest for Raymaker, whose own path to professional success has been unconventional. Little research has been done on what helps autistic people be successful in professions.
Cedars-Sinai neuroscientists have uncovered processes involved in how the human brain creates and maintains short-term memories. This study is the first clear demonstration of precisely how human brain cells work to create and recall short-term memories.
The implementation of state laws legalizing same-sex marriage was associated with a significant reduction in the rate of suicide attempts among high school students -- and an even greater reduction among gay, lesbian and bisexual adolescents, new Johns Hopkins Bloomberg School of Public Health research suggests.
Using magnetic resonance imaging (MRI) in infants with older siblings with autism, researchers from around the country were able to correctly predict 80 percent of those infants who would later meet criteria for autism at two years of age.
Older adults who live in poor and violent urban neighborhoods are at greater risk for depression, a study by researchers from UC Davis, the University of Minnesota and other institutions published Jan. 23 in the journal Health & Place has found.
A survey in the US notes a consistent increase in the occurrence of condomless anal sex among men, as well as a rise in how many sex partners they have. Although antiretroviral therapies (ART) have revolutionized the treatment and prevention of HIV infections, knowing that they have ART as a back-up makes people complacent. This can lead to increased risks, says study leader Seth Kalichman in an article in Springer's journal Archives of Sexual Behavior.
