Medical Xpress / Blood test boosts Alzheimer's diagnosis accuracy to 94.5%, clinical study shows
A protein lurking around in the blood can help with the accurate diagnosis of Alzheimer's disease. In a recent study, researchers from Spain investigated how blood-based biomarkers, such as a protein called p-tau217, affect ...
Phys.org / Supercomputer simulations reveal rotation drives chemical mixing in red giant stars
Advances in supercomputing have made solving a long‐standing astronomical conundrum possible: How can we explain the changes in the chemical composition at the surface of red giant stars as they evolve?
Phys.org / Martian volcanoes could be hiding massive glaciers under a blanket of ash
When we think of ice on Mars, we typically think of the poles, where we can see it visibly through probes and even ground-based telescopes. But the poles are hard to access, and even more so given the restrictions on exploration ...
Phys.org / Archived tree cores reveal why boreal forests are getting starved for nitrogen
Despite decades of industrial deposition, nitrogen availability in the boreal forest is steadily declining. In a new study published in Nature, researchers from the Swedish University of Agricultural Sciences using decades ...
Phys.org / Rocket re-entry pollution measured in atmosphere for first time
When part of a SpaceX rocket re-entered Earth's atmosphere exactly a year ago, it created a spectacuglar fireball that streaked across Europe's skies, delighting stargazers and sending a team of scientists rushing toward ...
Tech Xplore / AI and kindness: Are we morally obligated to be kind to Grok?
Would you ever kick your Roomba? Or leave a scathing review of the robot at a Thai restaurant who delivered your green curry? What about sending a mean message to ChatGPT?
Phys.org / Hair-width LEDs could eventually replace lasers
LEDs no wider than a human hair could soon take on work traditionally handled by lasers, from moving data inside server racks to powering next-generation displays. New research co-authored by UC Santa Barbara doctoral student ...
Phys.org / Iron Age massacre targeted women and children, new research reveals
New research has revealed that women and children were deliberately targeted in one of the largest prehistoric mass killings discovered in Europe. Archaeological investigations at the Gomolava burial sites in northern Serbia ...
Medical Xpress / Shoulder scans in most people above 40 show rotator cuff abnormalities, pain or not
Shoulder pain is the third most common musculoskeletal complaint seen by doctors, affecting approximately 18–31% of the global population each month. Up to 85% of these cases are due to problems with the rotator cuff (RC)—the ...
Phys.org / Jupiter's Galilean moons may have gained life's building blocks at birth
Southwest Research Institute was part of an international team that demonstrated how complex organic molecules (COMs), key chemical precursors to life, could have been incorporated into Jupiter's Galilean moons during their ...
Medical Xpress / Faster cancer screening? New AI system offers a better way to detect abnormal cells
One way cancer specialists detect the disease is by examining cells and bodily fluids under a microscope, a time-consuming and labor-intensive process called cytology. It involves visually inspecting tens of thousands to ...
Medical Xpress / New targeted base-editing tool corrects genetic brain disorder in mice
Researchers have found that a new base-editing gene therapy can help treat a rare neurodevelopmental disorder called Snijders Blok–Campeau syndrome caused by mutations in the CHD3 gene. A specialized gene-editing tool, ...
