Medical Xpress / Primate-specific DNA change reveals a new link to dementia-related neurodegeneration
Brain diseases, including dementia, have long been studied using experimental animals such as mice. However, differences between the human and animal genomes have raised concerns that some disease mechanisms may not be fully ...
Phys.org / Going beyond simple models of neural networks: Extended mean-field theory offers a better approach
Physics is most readily applied to relatively simple systems: a pendulum, two electrons colliding or the structure of the solar system. But when systems become complicated—when many particles interact with one another, in ...
Phys.org / Using AI to thwart election misinformation
Election rumors, such as unverified accounts of voter fraud, have run rampant in the U.S. in recent years. Powered by the speed of social media and artificial intelligence (AI), it can be hard for people to know what messages ...
Medical Xpress / Chronic pain is reflected in the folds and grooves of the cerebral cortex
Persistent pain often has no clear cause. However, studies show measurable differences in the structure and activity of the brains of those affected. This might explain why they experience chronic pain. "Many of our study ...
Tech Xplore / AI doesn't just play better chess—it manages complexity differently
For decades, chess has served as a laboratory for studying intelligence and decision-making. It is well established that today's chess engines can outperform even the strongest grandmasters. But far less is understood about ...
Phys.org / Major polluters are worsening the Western US water crisis: A new way to measure who's responsible
Climate change was once something scientists warned us about, and now it's a reality we are living in. In California's Central Valley, about one-third of climate-related groundwater loss between 2003 and 2024 can be attributed ...
Medical Xpress / Special aspherical glasses slow down childhood myopia progression, two-year trial finds
The number of people who need prescription glasses to correct their vision is increasing each year as nearsightedness, or myopia, becomes more common worldwide. Current projections suggest cases could reach 50% by 2050, affecting ...
Tech Xplore / How the war in Iran could serve as a 'turning point' for transition away from fossil fuels: Q&A
The war in Iran has strangled one of the world's most important oil-producing regions and trade routes, and gas prices have soared. UC Santa Barbara's Paasha Mahdavi, associate professor of political science and affiliated ...
Medical Xpress / Registry-based model predicts hip fracture risk better than current screening
A machine-learning tool built from Swedish national health registry data can predict hip fracture risk with high accuracy without an in-person assessment and identifies far more at-risk individuals than current clinical screening ...
Medical Xpress / Folic acid does not elevate formaldehyde in mice and humans
Folic acid—an essential vitamin added to flour and cereals and prescribed at high doses for cancer patients and people with blood disorders—does not elevate toxic formaldehyde in the body, according to a new study of mice ...
Phys.org / Parasitic plants act like genetic engineers by stealing and remodeling useful genes
Many plant species parasitize other plants by latching on and taking the nutrients their hosts need to survive. But sometimes, plants steal more than nutrients; they take genes.
Phys.org / 'Like uprooting tree stumps'—pulling nanoscale anchors creates tiny pores that could speed biosensor manufacturing
A new manufacturing method could help move the production of nanoscale sensors from specialized fabrication facilities to conventional semiconductor manufacturing plants.Publishing in Science Advances, researchers from KTH ...
