Phys.org / Sprint or marathon? Aging muscle stem cells shift from rapid repair to long-term survival
Aging muscles heal more slowly after injury—a frustrating reality familiar to many older adults. A UCLA study conducted in mice reveals an unexpected cause: Stem cells in aged muscle accumulate higher levels of a protein ...
Phys.org / Signaling output genes shed light on evolutionary crossroads of vertebrates
New research from the University of St Andrews has discovered a crucial piece in the puzzle of how all animals with a spine—including all mammals, fish, reptiles and amphibians—evolved. In a paper published in BMC Biology, ...
Phys.org / Angstrom-scale plasmonic gap boosts nonlinear light output by 2,000% per volt
Researchers at the Institute for Molecular Science (NINS, Japan) and SOKENDAI have demonstrated a more than 2000% voltage-induced enhancement of near-field nonlinear optical responses. To achieve this giant modulation, they ...
Medical Xpress / The brain's protein cleanup process may play a role in dementia
Microglia are the brain's immune cells that clean out debris, such as damaged proteins and old cell parts, to keep the organ healthy. But the very properties that make these cells so useful might also be a driving factor ...
Medical Xpress / Monthly infusion therapy could make life better for kidney transplant patients
A new study offers hope that kidney transplant patients could one day have a monthly treatment instead of multiple pills every day. The new treatment may also reduce side effects and increase the lifespan of the donor organ. ...
Medical Xpress / Survey finds 93% of IBD community support predictive testing and prevention strategies
A new Crohn's & Colitis Foundation–led survey of more than 1,500 people living with or at risk for inflammatory bowel disease (IBD) found that 93% would be interested in a test to predict their or their family's risk of ...
Medical Xpress / MDGA2 gene malfunction removes brain's excitatory 'brake' to trigger severe epilepsy, study finds
The DGIST Center for Synapse Diversity and Specificity has identified MDGA2 as a novel causative gene for developmental and epileptic encephalopathy (DEE), a rare and intractable neurological disorder occurring in infancy ...
Medical Xpress / Why aren't more older adults getting flu or COVID-19 shots?
This winter's brutal flu season isn't over, and COVID-19 cases have risen recently too. But a new poll taken in recent weeks shows that vaccination against both viruses lags among people 50 and over, and the national survey ...
Medical Xpress / Mutation map shows how key cancer gene drives tumor growth
Scientists have created a complete map showing how hundreds of possible mutations in a key cancer gene influence tumor growth. The study focused on CTNNB1, a gene that produces the protein β-catenin, which helps regulate ...
Tech Xplore / Musk Inc.? Billionaire combines his rocket and AI businesses before an expected IPO this year
Elon Musk is joining his space exploration and artificial intelligence ventures into a single company before what's expected to be a massive initial public offering for the business later this year.
Medical Xpress / Use of glucose-lowering SGLT2i drugs may help patients with gout and diabetes take fewer medications
Gout, a type of inflammatory arthritis caused by a buildup of uric acid (urate) in the body, affects 5.1% of U.S. adults (over 12 million), including 10% of those aged 65 or older. Urate is produced by the body when breaking ...
Phys.org / Hard-to-synthesize materials revived using AI: An LLM-based materials redesign technology
A research team led by Prof. Yousung Jung of the Department of Chemical and Biological Engineering at Seoul National University (SNU) has developed an innovative AI-based technology that uses large language models (LLMs) ...
