wo new studies assess how working memory — the memory we use on a day-to-day basis in decision-making processes — is affected by age, mood, and sleep quality and whether these factors impact memory together or on their own. Two new studies investigate how sleep quality, mood, and age affect a person’s working memory. Working...

Drug to treat malaria could mitigate hereditary hearing loss
by Case Western Reserve University The ability to hear depends on proteins to reach the outer membrane of sensory cells in the inner ear. But in certain types of hereditary hearing loss, mutations in the protein prevent it from reaching these membranes. Using a zebrafish model, researchers at Case Western Reserve University School of Medicine have...

Women caught in a pickle by their own immune systems
ASU scientists develop new hypothesis explaining sex differences in human diseases ARIZONA STATE UNIVERSITY Women get autoimmune diseases, such as multiple sclerosis, lupus and rheumatoid arthritis eight times more than men do. On the other hand, women have a smaller risk of getting non-reproductive cancers such as melanoma, colon, kidney and lung cancer. And while there are some...

I really have thought this can’t go on’: Loneliness looms for rising numbers of older private renters
Loneliness is increasingly recognized worldwide as a critical social issue and one of the major health hazards of our time. Our research shows older private renters are at high risk of loneliness and anxiety. This is a growing concern as more Australians are renting housing later in life. By contrast, only a small proportion of...

Early life stress plus over expressed FKBP5 protein increases anxiety behavior
by University of South Florida Researchers continue to dig for molecular clues to better understand how gene-environment interactions influence neuropsychiatric disease risk and resilience. An increasing number of studies point to a strong association between the FKBP5 gene and increased susceptibility to depression, anxiety, post-traumatic stress disorder and other mental health disorders. Adding to the growing evidence, a new preclinical study...

Approach Could Help in Treating Glioblastoma, Other Rare Cancers
Large randomized clinical trials can uncover biomarkers that indicate which cancer treatments are likely to work best for individual patients. But it’s been challenging to find these biomarkers in rarer cancers where such robust data aren’t available. Using a new approach that combines data from human tumors grown in mice with data from The Cancer Genome Atlas, a team led...

Brain changes may explain why exercise relieves autism in mice
By Catharine Paddock PhD Fact checked by Paula Field Exercise appears to alter the brain in ways that can reduce some of the characteristics of autism in mice. In mice bred to model autism spectrum disorder (ASD), scientists at the University of Tokyo in Japan found that exercise spurred the removal of surplus connections in brain...

Home Diagnostic Kit Can Detect Drugs In Blood And Urine Using Silicon Chips And An iPhone
A team of researchers from Vanderbilt University created a simple home diagnostics test that uses an item that many American adults already own: an iPhone. Sharon Weiss, a Cornelius Vanderbilt Professor of Engineering, and her students, in a new study, reported the development of low-cost porous silicon chips that work with a smartphone. “The novelty lies in the...
