A new study in the lab of Jason Stein, Ph.D., modeled brain development in a dish to identify cells and genes that influence infant brain growth, a trait associated with autism.
Medical Xpress / 'Listening in' on the brain's hidden language: Engineered protein detects the faintest incoming signals
Scientists have engineered a protein able to record the incoming chemical signals of brain cells (as opposed to just their outgoing signals). These whisper-quiet incoming messages are the release of the neurotransmitter glutamate, ...
Medical Xpress / Fathers' microplastics exposure tied to their children's metabolic problems
A study led by biomedical scientists at the University of California, Riverside, has shown for the first time that a father's exposure to microplastics (MPs) can trigger metabolic dysfunctions in his offspring. The research, ...
