Phys.org / Tracking forever chemicals across food web shows not all isomers are distributed equally
When University at Buffalo chemists analyzed samples of water, fish, and bird eggs, they weren't surprised to find plenty of per- and polyfluoroalkyl substances (PFAS). After all, these "forever chemicals" turn up nearly ...
Phys.org / Sunlight, water and air power a cleaner method for making hydrogen peroxide
Cornell scientists have discovered a potentially transformative approach to manufacturing one of the world's most widely used chemicals—hydrogen peroxide—using nothing more than sunlight, water and air. The research is ...
Phys.org / How cancer cells keep their chromosomes intact to continue dividing relentlessly
Scientists at Children's Medical Research Institute (CMRI) have made a major discovery about cancer cells. This new understanding could help make chemotherapy work better, reduce side effects, and lead to the development ...
Phys.org / Emissions from global wildfires far higher than previously thought
The total emissions of greenhouse gases and airborne particles caused by wildfires are almost 70% higher than previously assumed. Researchers at Wageningen University & Research discovered this in a long-term study conducted ...
Phys.org / Archaeological study challenges paleo diet, revealing humans have long eaten 'processed plant foods'
Humans evolved over hundreds of thousands of years to be the ultimate flexible eaters—chasing carbohydrates and fats from plant and animal sources alike. A new study in the Journal of Archaeological Research by researchers ...
Phys.org / Zapping stem cells could boost growth of new tissues and organs
Scientists in Melbourne have discovered how tiny electrical pulses can steer stem cells as they grow, opening the door to new improved ways of creating new tissues, organs, nerves and bones.
Phys.org / Researchers confirm new Rickettsia species found in dogs
Researchers from North Carolina State University have confirmed that a species of Rickettsia first seen in dogs in 2018 is a new species of bacteria. The new species, dubbed Rickettsia finnyi, is associated with symptoms ...
Phys.org / X-ray laser offers new look at protein movement inside cells
At European XFEL, researchers have observed in detail how the vital iron protein ferritin makes its way in highly dense environments—with implications for medicine and nanotechnology.
Phys.org / New levitating sensors could pave way to dark matter detection and quantum sensing
A new type of sensor that levitates dozens of glass microparticles could revolutionize the accuracy and efficiency of sensing, laying the foundation for better autonomous vehicles, navigation and even the detection of dark ...
Medical Xpress / Nitrogen dioxide exposure from gas stoves can be avoided by switching to electric
Twenty-two million Americans would no longer be breathing in unhealthy levels of nitrogen dioxide if they switched from gas and propane stoves to electric stoves.
Phys.org / Researchers use social media for real-time monitoring of heat experiences
A study led by health communications experts at the University of California, Irvine has yielded a new way to monitor heat equity in real time, facilitating the design of heat warning systems and targeted mitigation efforts ...
Medical Xpress / Oregon's first-in-the-nation hospital price cap cuts costs without compromising care
As health care costs continue to soar across the U.S., a growing number of states are setting limits on how much hospitals can charge. These policies, known as hospital payment caps, aim to curb spending by tying hospital ...
