Phys.org / El Niños have been more intense over the last 40 years than in the previous 1,000 years, coral records reveal
As an El Niño of historic proportions is taking shape in the tropical Pacific, a University of Michigan study has found that El Niño events have become nearly 40% stronger in the last 40 years than they were in the preindustrial ...
Medical Xpress / Largest ever molecular map of autism opens new paths to precision therapies
For more than two decades, researchers have identified hundreds of genes that increase the risk of autism spectrum disorder (ASD). Yet multiple fundamental questions have remained unanswered: Among them, how do mutations ...
Medical Xpress / Brain activity patterns may 'tag' experiences for later memory-making during sleep
The brain may "tag" experiences during learning to better consolidate memories of them during sleep, according to a study published Aug. 27 in the journal PLOS Biology by Dan Denis from the University of York, United Kingdom, ...
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 / 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 ...
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 ...
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 / 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 / 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 ...
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 ...
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 ...
