Medical Xpress / New wearable ring tracks glucose, ketone and other biomarkers in sweat simultaneously
Engineers at the University of California San Diego created a smart ring that simultaneously and continuously monitors up to four different chemical biomarkers from finger sweat. The biomarkers the smart ring can monitor ...
Phys.org / Quantum internet leaves the lab with first real-world entanglement over busy telecom fiber
Quantum information is notoriously fragile. Internet traffic is anything but. Yet Northwestern University scientists have demonstrated they can peacefully coexist inside the same fiber-optic cable.
Medical Xpress / How the heart's 'little brain' helps it function and protects it against stress
For years, scientists have known that the heart has its own network of nerves, the intrinsic cardiac nervous system (ICNS), sometimes called its "little brain." Exactly how it functions has remained something of a mystery, ...
Medical Xpress / AI analyzes surgical technique to improve prostate cancer care
The movements of a surgeon in a procedure—called "surgical gestures"—can be used to predict patient recovery, according to Cedars-Sinai investigators. Their findings, published in npj Digital Medicine, suggest this technology ...
Medical Xpress / Experimental plague vaccine strategy protects mice with missing key immune defenses
The plague has killed more people than World War II. The bacterium Yersinia pestis (Yp), which causes plague, has triggered three major pandemics throughout history, leaving behind a casualty toll of more than 200 million ...
Science X / Beneath pale ash, a quantum microscope reveals hidden traces of Neanderthal fire use preserved for millennia
An ancient hearth at El Salt (Spain) is giving up its secrets—not with flames, but with physics. Scientists have already established that Neanderthals used to make fires at this site (spanning from 80,000–45,000 years ago), ...
Medical Xpress / Early respiratory infections may explain half of younger siblings' earnings gap
Younger siblings are often portrayed as reckless, scatterbrained and less put-together than their older siblings. Social science researchers have underpinned these portrayals with data, showing that younger siblings obtain, ...
Medical Xpress / Scientists find compound that may help muscles stay strong as we age
Skeletal muscle is one of the first tissues to decline with age. This decline can lead to weakness, scarring, fat accumulation inside muscle and the loss of fast-twitch muscle fibers that are important for quick, powerful ...
Medical Xpress / Testosterone and combat readiness: What does the evidence really show?
Pete Hegseth, the U.S. defense secretary, recently announced plans to measure testosterone levels in U.S. soldiers with a promise of "ensuring you have the right testosterone levels to operate at your absolute best." Soldiers ...
Phys.org / Sperm whales blow bubbles to achieve restful, vertical sleep
New research from the University of St Andrews and Université de Neuchâtel has uncovered the mechanism that allows sperm whales to sleep in a unique vertical position just under the ocean surface.
Phys.org / How did inbred brown tree snakes take over the island of Guam?
If you look up invasive species in a textbook, there's a good chance you'll find a picture of a brown tree snake. Native to Australia and the South Pacific, the brown tree snake arrived on Guam sometime after World War II, ...
Medical Xpress / Newly identified molecule could help regulate sleep
Sleep is known to be essential for survival, as it allows both humans and other animals to rest, while the brain consolidates memories and clears out metabolic waste products. For many people worldwide, however, falling asleep ...
