Phys.org / New image sensor breaks optical limits
Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to unlocking microscopic details inside living cells. Yet despite decades of innovation, a fundamental ...
Medical Xpress / Alzheimer's disease can be reversed in animal models to achieve full neurological recovery
For over a century, Alzheimer's disease (AD) has been considered irreversible. Consequently, research has focused on disease prevention or slowing, rather than recovery. Despite billions of dollars spent on decades of research, ...
Phys.org / Glowing urine and shining bark: Scientists discover the secret visual language of deer
During mating season, when male white-tailed deer want to get noticed by the opposite sex and warn off rivals, they rub their antlers against trees and scrape the forest floor. Then they pee on these patches. But there is ...
Phys.org / Observations catch galaxy cluster in the process of merging
Astronomers have used the Keck Observatory's DEIMOS multi-object spectrograph to observe a nearby galaxy cluster designated RXC J0032.1+1808. As a result, they found that the cluster undergoes a major merging event. The finding ...
Tech Xplore / Unlocking corrosion-free Zn/Br flow batteries for grid-scale energy storage
Scientists have found a way to push zinc–bromine flow batteries to the next level. By trapping corrosive bromine with a simple molecular scavenger, they were able to remove a major barrier to the performance and lifespan ...
Phys.org / Resurrected tissue: Mechanism that enables regeneration after extensive damage solves a 50-year-old mystery
Like a phoenix rising from the ashes, our skin tissue—and in fact many types of epithelial tissue that lines and covers the body's organs—can respond to death and destruction with a burst of regeneration. This phenomenon, ...
Phys.org / Mechanism for twisted growth of plant organs discovered
From morning glories spiraling up fence posts to grape vines corkscrewing through arbors, twisted growth is a problem-solving tool found throughout the plant kingdom. Roots "do the twist" all the time, skewing hard right ...
Medical Xpress / Heart-brain connection: International study reveals role of vagus nerve in keeping the heart young
The secret to a healthier and "younger" heart lies in the vagus nerve. A recent study coordinated by the Sant'Anna School of Advanced Studies in Pisa and published in Science Translational Medicine has shown that preserving ...
Phys.org / An AI-based blueprint for designing catalysts across materials
Hydrogen peroxide is widely used in everyday life, from disinfectants and medical sterilization to environmental cleanup and manufacturing. Despite its importance, most hydrogen peroxide is still produced using large-scale ...
Medical Xpress / Rb1 identified as predictive biomarker for new therapeutic strategy in some breast cancers
A new study published in Science Translational Medicine by researchers at The University of Texas MD Anderson Cancer Center details a therapeutic vulnerability in patients with an aggressive subtype of triple-negative breast ...
Medical Xpress / Novel AI tool offers prognosis for patients with head and neck cancer
A team led by investigators at Mass General Brigham and Dana-Farber Cancer Institute has developed and validated an artificial intelligence (AI)–based noninvasive tool that can predict the likelihood that a patient's oropharyngeal ...
Tech Xplore / AI overestimates how smart people are, according to economists
Scientists at HSE University have found that current AI models, including ChatGPT and Claude, tend to overestimate the rationality of their human opponents—whether first-year undergraduate students or experienced scientists—in ...
