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 / XY or ZW? Gecko chromosomes reveal evolution's hidden playbook
Why do humans rely on XY chromosomes to determine sex, while birds use ZW—and many reptiles use neither, letting temperature decide instead? Sex determination is remarkably diverse across the animal kingdom. In genotypic ...
Phys.org / ASTRID traces 13.5 billion years of black hole and galaxy evolution
In dark skies at night, distant starlight twinkles and speaks to vast cosmic histories almost as old as time itself. New data from instruments such as NASA's James Webb Space Telescope are helping astrophysicists probe deep ...
Phys.org / Researchers reveal the unique 'tagging' mechanism that guides the sleeping brain in remembering key thoughts
Why do we remember certain moments while forgetting others? Every day, our minds are bombarded with thousands of pieces of information, yet our brains have a limited capacity to consolidate these experiences into lasting ...
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 ...
Phys.org / The physics of kiiking, Estonia's extreme sport of swinging
When an athlete swings upside down atop a 7-meter (23-foot) pendulum, it may seem like a feat of strength, courage or technique. A new study suggests it is something more fundamental: a striking demonstration of how intelligence ...
Phys.org / The wisdom of the egg cell: Oocyte epigenetic mark may help prevent excessive placental growth after fertilization
The genome—which contains genes encoded in DNA—acts as the fundamental blueprint of life. But what you might not know is that, in addition to this genetic information, we have something akin to an "instruction manual" for ...
Phys.org / Social media posts reveal how communities cope with extreme heat
As extreme heat becomes more frequent and intense across California, knowing which communities are struggling and what kind of help they need is increasingly important for protecting public health. A new UC Irvine study suggests ...
Tech Xplore / Nanoscale transistors achieve lower contact resistance with stepwise evaporation method
Metals, semiconductors and insulators are fundamental components of modern electronics. However, efforts to improve device performance have largely focused on semiconductor quality, while metal crystallinity has received ...
Medical Xpress / Next-generation RNA approach provides hope for genetic diseases missed by current drugs
Researchers at the University of Toronto have developed a next-generation RNA therapeutic approach with the potential to treat a wide range of genetic diseases that share certain disease-causing mutations. The work advances ...
Medical Xpress / Beyond hunger: Food insecurity in later life linked to dementia
Older adults who experienced food insecurity in both midlife and later life had nearly four times the risk of probable dementia as those who remained food secure, according to new University of Michigan research.
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 ...
