Scientists create molecular tool to remove toxic protein from neuronal models of dementia

Tool will be used to study accumulation of toxic protein in brain cells of patients with forms of dementia Represents first successful technique for targeted clearing of abnormal tau protein from human neurons Harnessing a probe used to image the brain in diagnosing Alzheimer’s disease and related forms of dementia, scientists at Dana-Farber Cancer Institute…

Teen series continue to feature stereotyped characters that perpetuate gender differences

A study has sought to identify and analyse adolescents’ favourite kind of character in Spanish teen series. Teen series are fictional and feature characters that specifically target teenagers and a younger audience.

Researchers discover neural patterns key to understanding disorders such as PTSD

Researchers at the University of California, Irvine have identified for the first time an imbalance in a key neural pathway that explains how some people reactivate negative emotional memories. The finding could help scientists unlock new ways to treat psychiatric disorders such as post-traumatic stress disorder. The study, “Multiplexing of Theta and Alpha Rhythms in…

New method for evaluating cancer risk of chemicals is quick, precise, inexpensive

(Boston)–Researchers from Boston University Schools of Medicine (BUSM) and Public Health have developed and evaluated a fast, accurate and cost-effective approach to assessing the carcinogenicity of chemicals–that is, whether exposure to a chemical increases a person’s long-term cancer risk. As a result, they have generated one of the largest toxicogenomics datasets to date, and have…
