Physicists say quantum mechanics may not need imaginary numbers after all

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.…

Scientists discover a hidden heart valve risk linked to gum disease

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…

Future moon landings could wipe out clues to how life began on Earth

Scientists are preparing for a new era of lunar exploration, but a new study suggests that every landing could leave behind more than footprints.

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…

Physicists recreate black hole energy extraction in the lab

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…

Deep-sea life has a secret food source scientists never expected

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.…

This ultrasound treatment may help stop arthritis before it starts

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…

Scientists discover how the brain rewires itself to truly multitask

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…

Scientists finally solved the mystery of Earth's greatest mass extinction

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…

Columbia scientists discover surprising link between serotonin and heart valve disease

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…

Why gold never tarnishes has finally been explained

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…

Common blood pressure drug could make cancer therapy far more powerful

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…

Experimental drug reverses severe fatty liver disease by repairing the gut

An experimental drug developed at Michigan Medicine has shown the ability to reverse severe fatty liver disease in animal studies by restoring gut health. The findings, published in The Journal of Clinical Investigation, suggest that targeting the connection between the gut and liver could offer a promising new approach for…

Europe just unveiled a new rival to SpaceX’s Starship

When SpaceX’s Starship lifted off from the Texas coast in the summer of 2023, it marked a milestone that aerospace engineers had discussed for decades but few expected to witness so soon. The towering stainless steel rocket, standing taller than a 30 story building, ignited all 33 of its engines…

Scientists discover the one nutrient beneficial parasites can't live without

Intestinal worms may help reduce inflammation, but new research suggests they can only do so when they have enough dietary fiber to thrive. Without sufficient fiber, these worms enter a hibernation-like state and lose their ability to provide anti-inflammatory benefits. The findings, published in Nature Communications, come from parasitologists at…
