A Dartmouth-led research team has identified a non-verbal, neural marker of autism. This marker shows that individuals with autism are slower to dampen neural activity in response to visual signals in the brain. This first-of-its kind marker was found to be independent of intelligence and offers an objective way to potentially diagnose autism in the future. The results are published in Current Biology.
Although some studies have linked high levels of testosterone to immoral behavior, a new study published in Nature Human Behaviour finds testosterone supplements actually made people more sensitive to moral norms, suggesting that testosterone's influence on behavior is more complicated than previously thought.
Travis Dunckley, a researcher at the ASU-Banner Neurodegenerative Disease Research Center, and Christopher Hulme, D. Phil, medicinal chemist at the Arizona Center for Drug Discovery based at the UA College of Pharmacy, are exploring a small molecule drug known as DYR219. The promising therapy, while still in the experimental stages, may succeed where other treatments have failed, and could be effective against a range of neurodegenerative illnesses in addition to Alzheimer's.
An international team of researchers led by scientists at Washington University School of Medicine in St. Louis has identified a pair of genes that influence risk for both late-onset and early-onset Alzheimer's disease.
This observational study examines changes in the age distribution of new obesity-associated cancer cases and nonobesity-associated cancer cases from 2000 to 2016 by sex and race/ethnicity.
Whether the experience of being a refugee increases the probability of developing a mental disorder such as schizophrenia was the focus of this study, a systematic review and meta-analysis that combined the results of nine studies involving 540,000 refugees in Denmark, Sweden, Norway and Canada. The relative risk of refugees developing nonaffective psychosis (which includes several mental disorders such as schizophrenia) was compared with the risk of natives of the host country and nonrefugee migrants there.
Hormone changes are known to alter insulin sensitivity and glucose metabolism, as well as interfere with women's sleep patterns. But little was known about the association between diabetes and sleep disturbances during the menopause transition until now, as a new study concludes that women with diabetes are at greater risk for sleep disturbances. Study results are published online today in Menopause, the journal of The North American Menopause Society (NAMS).
Scientists say the results have far reaching implications for how we understand the aging process, and how we might develop much-needed treatments for age-related brain diseases.
Experts have turned the tables on hospital rating systems and graded the rating systems on their strengths and weaknesses. Most got low grades. This is the first time hospital rating systems are rigorously compared. Ratings often offer conflicting, confusing results and do not provide an accurate picture, experts said. 'A lot of the so-called 'top hospitals' identified by some rating systems are not places that most physicians would refer their patients to,' said the lead author.
Contrary to what was widely communicated in media by high-profile figures, the movie 'Finding Dory' had no impact on increasing demand for blue tang fish, the species of the main protagonist. There was, however, an increase in online searches for that species, showing that blockbusters can drive information-seeking behavior about nature.
