A nearly 20-year-old scientific prediction has gained experimental support, revealing how graphene’s atomic structure could unlock new possibilities for advanced sensors and electronic devices. A wrinkle in graphene just a few atoms wide can dramatically alter how electricity behaves in the material. Scientists have now measured this effect in exceptionally sharp folds, providing experimental evidence […]
No Batteries, No Plugs: Scientists Create a Tiny Sensor That Powers Itself
Scientists have developed a tiny temperature sensor that harvests energy from magnetic fields near electrical wiring. Electrical wiring produces weak electromagnetic fields that typically go unnoticed, but researchers have found a way to turn some of that energy into a power source for tiny electronic devices. Scientists at the University of Arkansas (U of A) […]
Experts Spent Decades Searching for the Secret to Happiness. Here’s What They Found
After decades of studying happiness, some of the world’s leading researchers have changed how they live. Some of the world’s leading happiness researchers have changed how they live because of what they have discovered. After decades of studying well-being, several have made a conscious effort to spend more time with family and friends, reflecting one […]
Scientists Discover a Hidden Weakness in Cancer Cells That Could Transform Treatment
A new study reveals a previously overlooked weakness in certain cancer cells that could help researchers refine targeted treatments and reduce harmful side effects. Cancer cells that have lost one safeguard against DNA damage can become dependent on another, an enzyme called Wee1. Drugs that block Wee1 aim to exploit that weakness, but serious side […]
Obesity Could Disable a Key Defense Against Breast Cancer, Study Finds
A hopeful new direction in the fight against breast cancer may lie in the body’s own defenses, as mouse experiments suggest that protection weakened by obesity could be restored. Breast cancer develops in tissue surrounded by fat cells, and those cells may play a greater role in controlling tumor growth than previously understood. Researchers have […]
Ultra-Processed Foods May Be Changing How Children’s Brains Respond to Food
A yearlong study of 46 children suggests that brain responses to tempting food images may partly explain the link between ultra-processed diets and increasing body fat. Ultra-processed foods account for about 67% of the daily calories consumed by children in the United States. Although these products have been linked to weight gain and other health […]
Hubble Finds a Stunning Twist in How the Universe Emerged From Darkness
Hubble observations of nearby starburst galaxies challenge the idea that supernova winds helped reionize the early universe, suggesting young stars may have enabled radiation to escape before those winds formed. Powerful winds from exploding stars were thought to clear paths for ultraviolet radiation to escape early galaxies. A new study of nearby galaxies suggests those […]
This Giant Planet Orbits Its Star Every Two Days – but Something Is Very Wrong
Astronomers have discovered an unusual planet with an extremely hot host star and a highly eccentric orbit that challenges expectations for its class. A giant planet racing around an unusually hot star has caught astronomers’ attention because of its highly elongated orbit. Known as TOI-1355 b, the planet completes one revolution in roughly two Earth […]
This Alien Planet Should Have Lost Its Atmosphere Billions of Years Ago
James Webb Space Telescope observations suggest that exotic mineral clouds may be shielding a distant lava planet from its star. A rocky planet exposed to extreme heat from its star appears to reflect nearly three-quarters of the starlight that reaches it. Astronomers suspect silicate-mineral clouds could act as a protective sunscreen, helping the planet maintain […]
Beyond Bad Cholesterol: Scientists Uncover a Hidden Driver of Heart Disease
Protein patterns linked to TRL and Lp(a), two types of fat-carrying particles, suggest shared inflammatory pathways that could offer new targets for heart disease prevention. Lowering “bad” cholesterol substantially reduces the risk of a heart attack, yet some people still develop coronary heart disease after treatment brings their LDL cholesterol down to a recommended level. […]
