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 ...
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 ...
Phys.org / Plant-inspired water membrane filters CO₂ with constant selectivity and adjustable permeance
Gas separation membranes are vital for carbon capture, biogas upgrading, and hydrogen purification, all of which require the separation of carbon dioxide from gases like nitrogen, methane and hydrogen. However, the membranes ...
Phys.org / Mammal ancestors laid eggs—and this 250-million-year-old fossil proves it
A remarkable new discovery is shedding light on one of the greatest survival stories in Earth's history, and answering a decades-old scientific mystery. Lystrosaurus, a hardy, plant-eating mammal ancestor, rose to prominence ...
Phys.org / Chimpanzee empire falls apart in rare instance of division and deadly violence
The largest group of wild chimpanzees known to scientists has permanently split in two. In a study published in Science, researchers from the University of Texas at Austin and other institutions report the first clearly documented ...
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 / It's OK to love all the bees (the honey bees, too)
North America's bee populations are in trouble, but don't blame the honey bees. While some people argue that an overabundance of managed honey bees—those raised to help pollinate crops and produce honey—is causing native ...
Medical Xpress / Who should get the vaccine first? Lessons from the pandemic
It has been six years since the start of the COVID-19 pandemic, but one question remains relevant: Who should be first in line when vaccines are scarce? When COVID-19 vaccines first became available, supply was limited and ...
Phys.org / Decoy molecules trick soil bacteria into attacking persistent pollutants without genetic engineering
In a study published in the Journal of Materials Chemistry A, Nagoya University researchers demonstrated that native soil bacteria, when treated with decoy molecules, can degrade non-native compounds, including persistent ...
Medical Xpress / How the blood-brain barrier opens: Two proteins may guide future drug delivery
The cells that line the blood vessels in our brains are highly selective. By deciding which molecules are allowed in and out of our most important organ, the barrier these cells form is critical for keeping us alive. But ...
Phys.org / How AI's language barrier limits climate disaster responses
A message appears online during heavy flooding: "This rain no be small o, everywhere don red." Someone unfamiliar with the phrasing might hesitate. But for people in Nigeria, this message is immediate and clear: the flooding ...
