Ketamine found to increase brain noise

by Anastasia Lobanova, National Research University Higher School of Economics  Izhikevich, Edelman / Proceedings of the National Academy of Sciences of the United States of America An international team of researchers including Sofya Kulikova, Senior Research Fellow at the HSE University-Perm, found that ketamine, being an NMDA receptor inhibitor, increases the brain’s background noise, causing higher entropy of incoming sensory signals...

New HIV treatment shot given only twice a year could be a ‘game changer’

by Nada Hassanein, USA Today  Credit: Pixabay/CC0 Public Domain The Food and Drug Administration has approved Sunlenca, an injectable therapy to suppress HIV for patients who suffered drug resistance to other regimens. Experts say the new injectable, which works with less frequent dosing, can be a game changer for those whose infections don’t respond to...

Study reveals how chronic blood cancer transitions to aggressive disease

by Julia Evangelou Strait,  Washington University School of Medicine A study from Washington University School of Medicine in St. Louis suggests a strategy for preventing a chronic, slow-growing type of blood cancer from progressing to an aggressive form of leukemia. Shown is bone marrow from a mouse treated with a compound that blocks DUSP6, a key...

An mRNA vaccine strategy under study to fight the flu—as a shot and intranasal spray

by Delthia Ricks, Medical Xpress Credit: Unsplash/CC0 Public Domain Messenger RNA vaccine technology, once an arcane area of research, became household terminology because of the COVID-19 pandemic, and now scientists are working on an mRNA flu vaccine strategy that, at least in this study, involves a first dose administered as a shot but a booster administered...

TROUBLE WITH AMBIENT NOISE? COULD BE BRAIN CELLS FIRING

The result, they say, creates a “fuzzy” sound stage that makes it difficult for the brain to focus on one type of sound—such as spoken words—and filter out surrounding “noise.” Scientists have long linked inevitable age-related hearing loss to hair cells in the inner ear that become damaged or destroyed over time. But the researchers say their...
