Phys.org / Multiwavelength variability reveals dust structure in quasars
A research team has investigated quasar variability by tracking optical to mid-infrared (MIR) wavelengths of variability information. This multiband joint analysis provides an opportunity to probe the dust structure in the ...
Medical Xpress / Can certain foods prevent stomach cancer?
Can what you eat help you avoid getting stomach cancer? "Most cases of stomach cancer happen sporadically and are purely a matter of bad luck," says Sharon Shiraga, MD, an upper-gastrointestinal surgeon with Keck Medicine ...
Tech Xplore / Q&A: Ethical, legal and social issues—what does it take for new technology to be accepted?
How do cutting-edge science and technology respond to ethical and legal issues when incorporated into society? These issues are known as ethical, legal and social issues, or "ELSI" for short, and research on these issues ...
Phys.org / Florida reefs offer multimillion-dollar flood protection—if they survive
It's no secret that Florida's iconic coral reefs are in trouble. Repeated body blows from hurricanes, pollution, disease, climate change—and a near-knockout punch from a 2023 marine heat wave—has effectively wiped several ...
Phys.org / Ion accumulation in liquid–liquid phase separation regulates biomolecule localization, finds study
Researchers have identified a new physicochemical principle governing liquid–liquid phase separation in polymer solutions. Their research demonstrates that during the separation of a polymer mixture into two fluid phases, ...
Medical Xpress / CAR T cells with boosted BACH2 protein can fight cancer more effectively
UT Southwestern Medical Center researchers have discovered that increasing the levels of a protein called BACH2 makes engineered cancer-fighting immune cells behave more like stem cells, improving their therapeutic effectiveness. ...
Medical Xpress / Tiny molecules called tRNA halves may contribute to prostate cancer cell growth
Prostate cancer is the second-most common cancer in men. A new study from Thomas Jefferson University uncovered a new potential therapeutic target in tiny molecules called tRNA halves.
Medical Xpress / Predicting microbubble distribution for blood-brain barrier opening
A clinical study shows that preoperative dynamic susceptibility contrast (DSC) perfusion magnetic resonance imaging (MRI) can help predict how microbubbles will distribute in the human brain. This is a key step toward optimizing ...
Medical Xpress / Neuronal activity reveals new clues to ALS progression
Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disease with no cure and limited treatment options. One of the earliest signs of ALS is overactive brain signals known as cortical hyperexcitability. ...
Tech Xplore / GNSS-only method delivers stable positioning for autonomous vehicles in urban areas
Global navigation satellite systems (GNSS) are vital for positioning autonomous vehicles, buses, drones, and outdoor robots. Yet its accuracy often degrades in dense urban areas due to signal blockage and reflections.
Phys.org / New drug delivery mechanism could aid breast cancer treatment
In a study published in the Journal of Extracellular Vesicles, scientists from the UF Health Cancer Institute have found a way to make treatment for a notoriously aggressive breast cancer more effective. Using a delivery ...
Medical Xpress / Lack of employee flexibility to attend health care appointments during work hours has knock-on health impacts
Restricted access to health care appointments during typical working hours leads to poorer health-related quality of life, a University of Manchester–led study has found. The research explores how being unable to attend ...
