Medical Xpress / Aging blocks the retina's ability to regrow lost neurons, a first-of-its-kind study finds
A new study from the laboratory of Levi Todd, Ph.D., at Upstate Medical University has found that aging significantly limits the ability of support cells in the retina, called glia, to be reprogrammed into new neurons, a ...
Medical Xpress / CRISPR gene-editing therapy safely and continuously lowers cholesterol and triglycerides, first-in-human trial shows
A Cleveland Clinic first-in-human clinical trial has shown that a one-time infusion of a gene-editing therapy using CRISPR-Cas9 was effective and safe in reducing LDL ("bad") cholesterol and triglycerides in people with medication-resistant ...
Phys.org / A new type of LED light could bring significant efficiency gains
Researchers at Lund University have developed a new type of light-emitting diode based on thin, branched nanowires that could offer significantly higher efficiency and lower production costs than current technology. By controlling ...
Tech Xplore / Long AI conversations reveal misinformation vulnerabilities across seven leading chatbots
The results are in: Which AI model is the most fallible? Persuadable? Correctible? University of Arizona researchers assessed seven different generative AI large language models, or LLMs, for these three qualities during ...
Phys.org / Salt may have helped turn Earth into a frozen world 700 million years ago
Earth may have been pushed deeper into a global deep freeze by something surprisingly ordinary: salt. Around 700 million years ago, Earth entered periods of extreme glaciation known as Snowball Earth, when ice is thought ...
Medical Xpress / Energy-hungry tissues expand cleanup crews to clear worn-out mitochondria
The body's heart muscle (for pumping blood), skeletal muscle (for movement and posture) and brown fat (for heat production) each require a lot of energy and make a lot of waste. That waste needs to be managed.
Phys.org / Periodical cicadas may be doomed to extinction
Every 13 or 17 years, swarms of cicadas emerge from the ground, their black bodies, orange-tinged wings and ruby-red eyes enveloping trees and forests. It is a biological marvel unique in the insect world, and when it happens, ...
Phys.org / Magic-angle graphene provides evidence for unconventional superconductivity
Researchers have completely suppressed superconductivity in magic-angle graphene by screening interactions between electrons, helping resolve a long-running debate about the origin of the phenomenon.
Phys.org / Physicists finally put Feynman's path integral to the test
For nearly 80 years, physicists have relied on a thought experiment created by Richard Feynman to predict how quantum particles behave. For the first time, researchers in China have tested this trick directly in the lab.
Phys.org / Scientists discover how narwhals grow nature's only straight tusk
Narwhals have nature's only straight tusk, a single tooth up to three meters (10 feet) long, so strange they were sold as magical unicorn horns during the Middle Ages.
Tech Xplore / Brain activity patterns could help sharpen LLM deductive reasoning
Large language models (LLMs), the artificial intelligence systems underpinning the functioning of ChatGPT, Gemini and other similar conversational agents, are now widely used worldwide. In addition to processing, interpreting ...
Phys.org / Away from grand temples, a recycled Bronze Age burial mound became the focus of a Roman religious complex
The Romans were master engineers, building sprawling road networks, towering aqueducts and arenas across their empire. They were also good at recycling. New research has revealed that they turned the remains of a 4,000-year-old ...
