Scientists eager to explain brain rhythm boost’s broad impact in Alzheimer’s models

The sweeping extent to which increasing 40Hz “gamma” rhythm power in the brain can affect the pathology and symptoms of Alzheimer’s disease in mouse models has been surprising, even to the MIT neuroscientists who’ve pioneered the idea. So surprising, in fact, they can’t yet explain why it happens. In three papers, including two this year in Cell and Neuron, they’ve […]

Context may explain why dads are happier and less stressed than moms

Dads are often happier, less stressed and less tired than moms when taking care of kids, and researchers say these differences may come down to how and when childcare activities are split between parents. In a study led by Penn State, researchers looked at childcare through the lens of a “care context.” Going beyond measuring how much time mothers and […]

Gene protective against fruit fly heat-induced seizures may explain some human seizures

Researchers identified a gene in fruit flies that helps prevent the hyperexcitability of specific neurons that trigger seizures. In humans, mutations in the gene may be linked to seizures associated with Long QT Syndrome. A research team led by Yehuda Ben-Shahar of Washington University in St. Louis report these findings in a paper published 8th August in PLOS Genetics. The […]

Stem cell differences could explain why women are more likely to develop adrenal cancer

Scientists have discovered a potential biological reason why women are more likely to develop adrenal disorders, including cancer. According to the researchers, the answer could lie in the increased turnover of hormone-producing cells found in the adrenal glands of females. The adrenal gland is a hormone producing organ that sits on top of the kidneys. The outer part, or cortex, […]

Study may explain why immunotherapy not effective for some patients with metastatic melanoma and kidney cancer

White blood cells known as B cells have been shown to be effective for predicting which cancer patients will respond to immune checkpoint blockade (ICB) therapy, according to a study at The University of Texas MD Anderson Cancer Center. Study results will be presented April 2 at the AACR Annual Meeting 2019 in Atlanta. The study, led by Jennifer Wargo, […]
