Phys.org / Carbon-based catalyst can use sunlight to degrade PFAS
An international team of scientists led by the University of Bath has developed a new catalyst—a substance that speeds up chemical reactions—that uses sunlight to break down so-called "forever chemicals" prevalent in ...
Phys.org / How AI can improve the quality of peer review
A new AI coach for scientists has been shown to significantly improve the quality of peer reviews, making them clearer and more helpful for authors. Peer review is essential to ensuring the integrity of scientific publications, ...
Medical Xpress / Three-drug combo targets immune suppression to overcome melanoma resistance
For patients with advanced melanoma without BRAF mutation who no longer respond to immune checkpoint inhibitors, treatment options remain frustratingly limited. A new study from Vanderbilt researchers led by Professor Emerita ...
Phys.org / Earth's mantle may have been cooler than thought before Pangea's breakup
When the supercontinent Pangea began to fragment around 200 million years ago during the Early Jurassic, it reshaped the face of the planet. Vast new oceans opened, continents drifted apart and the familiar geography of today ...
Phys.org / What is an exoplanet? An astrophysicist explains why they are vital for finding alien life
Scientists might have just found Earth's icy, distant cousin a few hundred light-years away. HD 137010 b is one of thousands of exoplanets, or planets that orbit other stars, and is potentially the first Earth-like one that ...
Medical Xpress / Pancreatic cancer may begin hiding from the immune system earlier than we thought
A new study from researchers at the Hebrew University of Jerusalem provides fresh insight into how pancreatic cancer may begin taking shape years before it is clinically detected. The research shows that early precancerous ...
Phys.org / Astronomers discover rare super-Jupiter orbiting distant star
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new exoplanet orbiting a distant star known as TIC-65910228. The newfound alien world is slightly larger and ...
Medical Xpress / Nearly half of Americans unaware processed meat is tied to colorectal cancer, poll finds
Just before National Colorectal Cancer Awareness Month begins in March, a new Physicians Committee for Responsible Medicine/Morning Consult poll found that nearly half of Americans aren't aware that eating processed meat ...
Phys.org / Color-changing nanopigment sensor tracks pH one to ten with stable, repeatable readings
Chemists in South Korea have created a stable color-changing sensor that displays an easily quantifiable response to the pH of its surroundings. Published in Microsystems & Nanoengineering, Dong-Hwan Kim and colleagues at ...
Phys.org / Satellite imaging is now vital for disaster management: But there are dangerous gaps
The extreme weather events and resulting destruction that have hit New Zealand this summer are not only signs of a changing climate. They also highlight the now indispensable role of remote sensing satellite technology.
Medical Xpress / More than eco-anxiety: Study exposes emotional fallout of climate crisis for youth
A few years ago, researcher Maya Gislason's young child came home from school with her crayon drawing of Earth in 2020 and 2050. "The first was blue and green; the second was a planet on fire," she says. "Her question to ...
Phys.org / Using high-energy sparks to degrade pollutants without generating waste
A study published in the Chemical Engineering Journal proposes a new approach to environmental remediation of pharmaceutical pollutants in water flows. This approach is based on a phenomenon known as "sparks," which refers ...
