Medical Xpress / Smartwatch and blood test data combine to better predict insulin resistance and diabetes
Around 20–40% of the general population are estimated to have insulin resistance—a condition where insulin begins to be less effective in the body, and glucose regulation becomes more difficult. Eventually, this can lead ...
Medical Xpress / Changes in pace of epigenetic clocks over time may help predict mortality risk
The age on your driver's license may not be the same age as the cells in your body. Scientists use something called an epigenetic clock, which looks at certain chemical tags in DNA to measure your biological age, or how fast ...
Phys.org / Natural textile fibers may persist for more than a century in lake sediments
Natural fibers promoted as sustainable alternatives to plastic, including cotton and wool, have been found preserved in a U.K. lake for more than a century—challenging assumptions that they quickly biodegrade in the environment. ...
Phys.org / The cactus on your desk is an evolution speed machine
The cactus on your windowsill may grow slowly, but new research shows that cacti are surprisingly fast at creating new species. Biologists have long thought that pollinators and specialized flowers drive the formation of ...
Phys.org / Bell-bottoms today, miniskirts tomorrow: Math reveals fashion's 20-year cycle
Fashion insiders and beauty magazines have long cited the "20-year-rule"—the idea that clothing trends often resurface every two decades. According to Northwestern University scientists, that observation isn't just anecdotal. ...
Tech Xplore / AI chatbots' tendency to always agree may reinforce delusions in vulnerable users
The integration of large language model-based AI chatbots into multiple facets of our everyday lives has opened us up to advantages that would have been considered impossible even a decade ago. The same development has, however, ...
Tech Xplore / Nvidia says restarting production of China-bound chips
Nvidia chief Jensen Huang on Tuesday said the AI technology powerhouse is restarting production of its high-performance chips for clients in China.
Phys.org / Light-activated material offers new approach to carbon dioxide conversion
Scientists have developed a new material that can use sunlight and water to convert carbon dioxide (CO₂) into carbon monoxide (CO)—a key building block for making fuels, plastics, pharmaceuticals and other everyday chemicals. ...
Dialog / What happens to cigarette butts after 10 years in the environment
Cigarette butts are the most common form of litter worldwide. Trillions are discarded every year in cities, parks, beaches, along railway tracks and roadside environments. Despite their small size, these remnants of smoked ...
Phys.org / Scientists discover new heavy proton-like particle at CERN
Scientists from the University of Manchester have played a leading role in the discovery of a new subatomic particle at CERN's Large Hadron Collider (LHC). The particle, known as the Ξcc⁺ (Xi‑cc‑plus), is a new type ...
Phys.org / AI model predicts chemical effects on gene expression, speeding drug discovery
Inside a diseased cell, the genes are in chaos. Some are receiving signals to overproduce a protein. Others are reducing activity to abnormal levels. Up is down and down is up. The right molecule could restore order, reversing ...
Phys.org / How humans took over the planet: The role of cultural evolution
Humans really do rule the world. We took over fast and far, more than any other wild vertebrates. We inhabit nearly every corner of the world, and can thrive in deserts, tropical rainforests and even extremely cold climates. ...
