A new USC led study of more than 214,000 older adults from 14 countries and regions suggests that preventing dementia may require different strategies in different parts of the world. Researchers found that many of the most important modifiable dementia risk factors, including low education, high blood pressure, and smoking,…
Quantum mechanics is the branch of physics that explains how matter and energy behave at the atomic and sub atomic scale. Developed in the early 1900s by pioneers including Max Planck, Niels Bohr, Werner Heisenberg, and Erwin Schrödinger, it has become one of the most successful scientific theories ever created.…
Bacteria that cause gum disease may do more than damage your teeth. New preliminary research suggests they could also contribute to the buildup of calcium in the heart’s aortic valve, potentially leading to calcific aortic valve stenosis (CAVS), a common and potentially life threatening heart valve disorder. The findings were…
Scientists are preparing for a new era of lunar exploration, but a new study suggests that every landing could leave behind more than footprints. Researchers found that methane released in spacecraft exhaust may spread across the moon surprisingly quickly, potentially contaminating regions that could preserve ancient chemical clues about how…
Citizen scientists have helped researchers uncover how parental care evolved in harvestmen, a group of spider like arachnids, by contributing observations through the popular nature platform iNaturalist. The findings, published in the Zoological Journal of the Linnean Society, reveal that parental guarding behavior has appeared, disappeared, and evolved again multiple…
New research has revealed that tau, a protein best known for its connection to Alzheimer’s disease, is also essential for creating long lasting memories. The discovery provides new insight into how healthy memory works and could help guide future efforts to develop treatments for dementia. The study, led by Flinders…
More than 50 years ago, physicist Sir Roger Penrose proposed a remarkable idea: under the right conditions, it might be possible to extract energy from a rapidly spinning black hole. In his concept, a particle entering the black hole’s ergosphere, a region where spacetime is dragged along by the object’s…
Scientists have uncovered an unexpected source of food in the deep ocean that could change how researchers understand both marine ecosystems and Earth’s carbon cycle. A new study from the University of Southern Denmark (SDU) suggests that deep ocean microbes are not living in such a nutrient-starved environment after all.…
Researchers at The University of Alabama in Huntsville (UAH), part of The University of Alabama System, have identified a promising new use for continuous low-intensity ultrasound that could one day help treat joint injuries and reduce the risk of post-traumatic osteoarthritis. Their findings suggest the non-invasive approach may shift the…
Researchers at Georgetown University have uncovered new evidence that the brain physically reorganizes itself as people master a skill, allowing well-practiced tasks to become automatic. The findings challenge the long-standing idea that humans cannot truly multitask, suggesting that with enough experience, the brain can perform certain activities simultaneously instead of…
A new Stanford led study has provided the strongest evidence yet for why some marine animals survived Earth’s largest mass extinction while many others disappeared forever. The findings not only explain how modern ocean ecosystems came to be, but also offer a cautionary glimpse of how today’s warming oceans could…
Serotonin is usually associated with mood, sleep, and digestion. But research published in 2023 suggests this chemical messenger may also influence a small structure that performs a vital job during every heartbeat: the mitral valve. The multicenter investigation found evidence that reduced activity of the serotonin transporter may accelerate damaging…
Gold has long been valued for its brilliant, long lasting shine. Now, researchers at Tulane University have uncovered an important reason why the precious metal remains so resistant to tarnishing. Their findings show that gold’s durability is not determined by its chemistry alone. Instead, the arrangement of atoms on its…
Parkinson’s disease may spread through the brain with the help of two proteins found on the surface of motor neurons, according to new research from Yale School of Medicine (YSM). The discovery could open the door to treatments designed to slow or even stop the disease instead of only managing…
A medication that has long been used to treat high blood pressure could also help make an important class of cancer drugs much more effective, according to new research from Dartmouth Cancer Center (DCC). The study found that the FDA approved drug telmisartan significantly boosted the cancer killing activity of…
