Implantation of a stent-like flow diverter can offer one option for less invasive treatment of brain aneurysms -- bulges in blood vessels -- but the procedure requires frequent monitoring while the vessels heal. Now, a multi-university research team...
A new study using machine learning has identified brain-based dimensions of mental health disorders, an advance towards much-needed biomarkers to more accurately diagnose and treat patients. A team at Penn Medicine led by Theodore D. Satterthwaite, MD, an...
Valerie Stull was 12 when she ate her first insect. "I was on a trip with my parents in Central America and we were served fried ants," she says. "I remember being so grossed out initially, but when I...
A new study by Harvard Medical School researchers sheds light on the molecular repertoire of neurons responsible for encoding sound in the inner ear, which could inform efforts to develop therapeutic strategies to treat or protect against hearing...
A City of Hope researcher has developed a stem cell model to assess possible treatments for a rare nervous system disorder that is in the same disease group as Alzheimer's disease, Parkinson's disease and amyotrophic lateral sclerosis (ALS). The...
Henipaviruses are among the deadliest viruses known to man and have no effective treatments. The viruses include Hendra, lethal to humans and horses, and the Nipah virus, a serious threat in East and Southeast Asia. They are on...
Proteins -- the molecular machines that drive the processes underlying biology -- are made from just 20 canonical building blocks called amino acids. For nearly two decades, scientists have sought methods to engineer new amino acids to build...
Johns Hopkins Medicine scientists say they have found new evidence in lab-grown mouse brain cells, called astrocytes, that one root of Alzheimer's disease may be a simple imbalance in acid-alkaline -- or pH -- chemistry inside endosomes, the...
Alcohol increases the mortality of young but not old mice infected with the tuberculosis-causing bacterium Mycobacterium tuberculosis (Mtb), and this effect is mediated by the production of a protein called interferon-alpha (IFN-α). The study, led by Deepak Tripathi...
FOXP2, a gene implicated in affecting speech and language, is held up as a textbook example of positive selection on a human-specific trait. But in a paper published August 2 in the journal Cell, researchers challenge this finding....
