Phys.org / Hydroxyl radicals in UV-exposed water reveal surprising reaction pathway
How do radicals form in aqueous solutions when exposed to UV light? This question is important for health research and environmental protection. For example, with regard to the overfertilization of water bodies by intensive ...
Phys.org / Carbon nanotube fiber sensors achieve record measurement error below 0.1%
Skoltech scientists, in collaboration with colleagues from China and Iran, have taken a major step toward creating highly precise carbon nanotube fiber (CNTF)-based sensors. In a paper published in the iScience journal, the ...
Phys.org / Liquid-like histone H1 'glues' nucleosomes, reshaping how DNA compacts
DNA inside the nucleus is not packed as a rigid regular fiber—linker histone H1 dynamically binds and loosely "glues" nucleosomes together, creating a dynamic, fluid organization that can still support essential genome functions.
Phys.org / From Asgard to Earth: Tiny tubes may reveal the moment complex life began
Stromatolites—and their close relatives, microbial mats—could be mistaken for what seems like a bunch of old dark rocks. But instead, they are dense, layered communities of microbes. Long before complex life such as animals ...
Medical Xpress / Long non-coding RNA may be a promising therapeutic target for cancer
Northwestern Medicine scientists have discovered that a specific long non-coding RNA activates oncogenic signaling pathways in prostate cancer cells and drives tumor progression, underscoring its potential as a therapeutic ...
Tech Xplore / Compression technique makes AI models leaner and faster while they're still learning
Training a large artificial intelligence model is expensive, not just in dollars, but in time, energy, and computational resources. Traditionally, obtaining a smaller, faster model either requires training a massive one first ...
Medical Xpress / A 'wake-up call' from leading sleep scientists: Nighttime warming threatens the sleep of billions
As the world heats up, nights are warming faster than days where most people live—and this ambient heat affects how well and how long people sleep. A new article by eminent sleep scientists, including the presidents of the ...
Phys.org / AI diffusion models tailor drug molecules to custom-fit protein targets, speeding drug development and evaluation
University of Virginia School of Medicine scientists have developed a bold new approach to drug development and discovery that could dramatically accelerate the creation of new medicines. UVA's Nikolay V. Dokholyan, Ph.D., ...
Phys.org / A smarter way to build vaccines: Scientists harness AI to target emerging alphaviruses
A team of scientists at The University of Texas Medical Branch (UTMB), led by Nikos Vasilakis, Ph.D., and Peter McCaffrey, MD, has developed a new computational pipeline that could dramatically accelerate the development ...
Medical Xpress / People use the same neurons to see and imagine objects, study shows
Why can images of things we have seen seem so real when we later recall them from memory? A new study led by Cedars-Sinai Health Sciences University investigators sheds light on the answer. The research shows that the same ...
Phys.org / Deadly heat thresholds have already being crossed in six recent heat waves, study shows
Deadly heat wave events are occurring at temperatures and humidity levels previously thought to be survivable, according to a new paper by a team of international researchers, including from The Australian National University ...
Medical Xpress / Novel gene-based therapy helps nerves heal better after severe injury
Peripheral nerve injuries, often caused by traumatic events such as car accidents, falls or battlefield injuries, can leave patients with long-term weakness, numbness or loss of function. Despite surgery and advances in understanding ...
