A study of nearly 13,000 adults found that people consuming the most artificial sweeteners experienced a 62% faster decline in memory and thinking skills, equivalent to approximately 1.6 additional years of brain aging. Six popular sweeteners were linked to faster cognitive decline, raising concerns about the long-term brain health effects of common sugar substitutes, although causation was not e…

Mathematicians have uncovered what they argue is a fundamental flaw in the standard model of the universe, potentially challenging the need for dark energy. Their calculations suggest that the mathematical framework used to describe cosmic expansion is inherently unstable and that the universe could accelerate naturally under Einstein's original theory of gravity. The findings also raise surprisi…

NASA’s Juno spacecraft has discovered that Jupiter uses a surprisingly complex system of powerful plasma waves and multiple shock regions to defend against the solar wind. The findings reveal major differences between Jupiter and Earth and could help scientists understand the enormous shock waves produced by exploding stars.

Ancient ice discovered high in Tibet may be more than 128,000 years old, preserving an extraordinary record of Earth's climate that scientists previously thought had been lost. The discovery reveals a rare glimpse into the last ice age and could reshape our understanding of how glaciers survive dramatic changes in global climate.

A remarkably preserved elephant tooth dating back nearly 700,000 years has revealed a surprisingly lush prehistoric world where giant elephants and early humans lived side by side. Discovered in northern Israel alongside ancient stone tools, the tooth belonged to a straight-tusked elephant, one of the largest land mammals of the Ice Age.

Getting more daylight could be linked to a surprisingly powerful benefit for brain health. In a study of more than 87,000 adults, researchers found that higher daytime light exposure was associated with a 16% lower risk of dementia, with longer exposure to bright light linked to even greater reductions. Remarkably, getting less than 42 minutes of bright daylight daily was a stronger predictor of …

Cranberry juice may offer an unexpected benefit beyond its reputation for helping prevent urinary tract infections: protecting teeth from decay. Researchers at the University of Illinois Chicago discovered that pure, unsweetened cranberry juice slowed the regrowth of dental plaque bacteria and reduced their production of acids that damage tooth enamel. The secret may lie in naturally occurring co…

Scientists have identified a weakened brain signal that may connect several seemingly unrelated symptoms of schizophrenia, including sensory processing difficulties, disorganized speech, and greater symptom severity. The surprising discovery could help explain the disorder's underlying mechanisms and potentially lead to earlier detection and new treatments.

Researchers have discovered a small group of brain cells that prevents dangerous blood pressure swings, even when average readings appear normal. The finding reveals a hidden source of cardiovascular risk and could open the door to new treatments that protect the heart and brain.

Scientists have defied a long-standing rule of laser physics by generating X-rays with much higher energies than conventional theory predicts. The surprising discovery reveals how two electrons working together can overcome a previously accepted limit, opening new possibilities for quantum research.

Scientists have uncovered seven surprising stages that space rocks go through as they hurtle toward Earth, revealing that melting and violent fragmentation, rather than simple evaporation, determine their fate. The discovery could help explain why meteorites scatter across the ground and how dangerous asteroids explode in Earth's atmosphere.

Scientists have discovered that magma deep inside Earth can store surprising amounts of extra oxygen, potentially revealing a hidden contributor to our planet's oxygen-rich atmosphere. The findings suggest that ancient volcanic eruptions may have helped transform Earth's atmosphere billions of years ago, with implications for understanding life on other planets.

A new Finnish study reveals that just 30 minutes in a sauna can temporarily flood the bloodstream with additional white blood cells, potentially helping the immune system patrol the body and detect threats. The surprising response resembles the immune boost seen during exercise and may help explain some of the health benefits linked to sauna bathing.

Scientists have developed a new technology that could make electric vehicle batteries smaller, lighter, and longer-lasting, potentially allowing cars to travel farther on a single charge. By borrowing precision manufacturing techniques from computer chip production, they found a way to prevent damaging lithium buildup that has held back next-generation batteries.

Researchers have discovered a surprising hidden ability in Europe's familiar black-and-yellow fire salamanders: they glow green and cyan under ultraviolet light. The mysterious fluorescence comes mainly from glands in their skin and their toxic secretions, which can continue glowing for more than 24 hours after being released.
