(Boston)–A major obstacle in understanding and treating posttraumatic stress disorder (PTSD) is its clinical and neurobiological heterogeneity. In order to better treat the condition and address this barrier, the field has become increasingly interested in identifying subtypes of PTSD based on dysfunction in neural networks alongside cognitive impairments that may underlie the development and…
After pouring beer into a glass, streams of little bubbles appear and start to rise, forming a foamy head. As the bubbles burst, the released carbon dioxide gas imparts the beverage’s desirable tang. But just how many bubbles are in that drink? By examining various factors, researchers reporting in ACS Omega estimate between 200,000 and…
Human clinical trials have begun on a new vaccine candidate that may protect against not only SARS-CoV-2, the virus that causes COVID-19, but against at least two of the variants emerging around the world. The development of this new vaccine was guided by structural information on the virus obtained at the Advanced Photon Source (APS),…
April 21, 2021 – Consuming a diet high in pro-inflammatory foods – including foods that contain refined carbohydrates and sugar as well as polyunsaturated fats – may be associated with increased odds of developing testosterone deficiency among men, suggests a study in The Journal of Urology®, Official Journal of the American Urological Association (AUA).

Women who experience partner violence at a young age don’t always show physical signs of abuse and don’t always disclose — or recognize — the dangerous position they’re in. A new study from Michigan State University is one of the first to examine multiple factors that influence young women’s disclosure of partner violence that occurred…
A new study published in the Journal of the American Geriatrics Society has found that listening to music can help older adults sleep better. Researchers from the National Cheng Kung University Hospital in Taiwan combined the results of past studies to understand the effect that listening to music can have on the quality of older…
The correlation also held whether or not people were taking sleep medication and whether or not they had a mutation called ApoE4 that makes people more likely to develop Alzheimer’s, Dr. Sabia said. “The study found a modest, but I would say somewhat important association of short sleep and dementia risk,” said Pamela Lutsey, an…
In Finland, a relatively egalitarian society, people tend not to be fixated on “keeping up with the Joneses.” “People often do pretty well in social comparison,” said Antti Kauppinen, a philosophy professor at the University of Helsinki. “This starts from education; everybody has access to good education. Income and wealth differences are relatively small.” David…
The Morton Cranial Collection, assembled by the 19th-century physician and anatomist Samuel George Morton, is one of the more complicated holdings of the University of Pennsylvania Museum of Archaeology and Anthropology. Consisting of some 1,300 skulls gathered around the world, it provided the foundation for Morton’s influential racist theories of differences in intelligence among races,…
Scientists have produced a comprehensive roadmap of muscle aging in mice that could be used to find treatments that prevent decline in muscle mobility and function, according to a report published today in eLife. The study reveals which molecules in the muscle are most significantly altered at different life stages, and shows that a molecule…
