Several popular sugar substitutes may not be as harmless as they seem. Adults who consumed the most artificial sweeteners showed substantially faster declines in memory and thinking, especially if they were under 60 or had diabetes. The highest intake was linked to cognitive aging roughly 1.6 years faster than the lowest intake. Researchers stressed that more studies are needed before concluding that sweeteners are the cause.

Sleeping about an hour and 20 minutes less each night for six weeks caused participants to gain weight and spend more time inactive. Researchers found that even mild, realistic sleep loss, similar to what many adults experience, had measurable effects. They warn that if this pattern continues over months or years, the health consequences could become much more significant, including a higher risk of diabetes and heart disease. Read more ›

Scientists at Nanyang Technological University in Singapore have discovered a surprisingly simple way to create exotic light structures called optical skyrmions using a 200-year-old optical effect known as the Poisson spot. Instead of relying on expensive, highly engineered materials, they simply shine a laser at a tiny circular disc, producing stable swirling patterns in light that researchers believe could one day help power advanced data storage, communications, and computing technologies.

A new study suggests the brain begins making decisions much earlier than scientists previously thought. Researchers found that even primary sensory regions are influenced by higher brain areas through rapid feedback loops, rather than simply passing information forward. This more dynamic view of brain function could help engineers design future AI systems that think more like biological brains while using far less power. Read more ›

An unexpected study found that young non-smokers with healthier diets had higher rates of lung cancer, raising questions about whether pesticide exposure from conventionally grown produce could play a role. Researchers stress that the findings are preliminary and require further studies before any conclusions can be drawn. Read more ›

Scientists have developed a new framework that could finally apply the laws of thermodynamics to real, ever-changing black holes instead of only perfectly stable ones. The advance may improve our understanding of black hole mergers, evaporation, and the powerful gravitational wave events detected by observatories like LIGO. Read more ›

Researchers analyzing data from more than 214,000 people found that dementia risk factors differ widely across countries, challenging the idea of a one-size-fits-all prevention strategy. At the same time, they uncovered surprisingly consistent patterns that could help shape smarter, more targeted public health efforts. Read more ›

Physicists from Heinrich Heine University Düsseldorf (HHU) have examined a fundamental property of quantum mechanics in collaboration with the German Aerospace Center (DLR). In the scientific journal Physical Review Letters, they show that this theory does not necessarily need to be formulated with imaginary numbers – real numbers can in fact also be used. The American Physical Society has also dedicated a “Highlight” to these findings in its Physics Magazine. Read more ›

Researchers found that bacteria linked to gum disease may help drive the development of calcific aortic valve stenosis by triggering inflammation and calcium buildup in the heart valve. The early findings suggest that keeping gums healthy could play a role in reducing the risk of this serious heart condition. Read more ›

A new study suggests spacecraft exhaust could quickly contaminate the moon's most scientifically valuable regions, potentially masking ancient clues about how life began on Earth. Researchers say future lunar missions should consider new ways to reduce and monitor this pollution before it becomes widespread. Read more ›

Citizen scientists have helped researchers solve a long-standing mystery about how parental care evolved in harvestmen. Using photos and observations from iNaturalist, scientists more than doubled the known cases of egg-guarding behavior and discovered that maternal and paternal care followed different evolutionary paths. The project, completed in just days with help from public data, shows how citizen science is transforming biological research on a global scale. Read more ›

Researchers found that tau is essential for turning new experiences into lasting memories by helping organize the brain's memory-storing cells. The mouse study also revealed how abnormal tau may contribute to Alzheimer's by disrupting both the formation of new memories and the recall of existing ones. Read more ›

Researchers have recreated the physics of extracting energy from a spinning black hole using a stationary device that produces synthetic ultrafast rotation. The achievement transforms a long-standing theoretical idea into a practical experiment and could inspire new advances in optics, wireless communications, and quantum science. Read more ›

Scientists discovered that extreme deep-sea pressure squeezes valuable nutrients out of sinking organic particles, providing an unexpected food source for ocean microbes. The finding could rewrite our understanding of both deep-ocean ecosystems and how carbon is stored on Earth. Read more ›

A simple, non-invasive ultrasound treatment could one day help injured joints heal instead of remaining trapped in a cycle of damaging inflammation. Researchers at The University of Alabama in Huntsville found that continuous low-intensity ultrasound encouraged key immune cells called macrophages to shift from an inflammatory state toward one that supports tissue repair.

Practice may do more than make perfect. Researchers found that extensive training physically reorganizes the brain, allowing learned tasks to bypass the prefrontal cortex and run through specialized circuits instead. By freeing the brain's "thinking" center, people became better at performing another task at the same time, challenging the long-held idea that humans only switch rapidly between tasks rather than truly multitask.

Why do beaches today have seashells from clams and snails instead of brachiopods? A new study suggests the answer lies in Earth's greatest mass extinction, when warming oceans and falling oxygen levels wiped out animals that couldn't adapt. Species with body plans and metabolisms better suited to the changing conditions survived and went on to dominate the seas, offering a glimpse of how modern marine life could respond to climate...

Scientists have uncovered evidence that serotonin, the chemical best known for regulating mood, may also speed the progression of a common heart valve disease in some people. The research suggests that patients with degenerative mitral regurgitation who take SSRI antidepressants and carry a specific genetic variant may develop severe valve damage sooner, potentially requiring surgery at a younger age.

Gold may have a secret self-defense system that helps it resist tarnishing. Researchers discovered that atoms on gold surfaces reorganize themselves into patterns that block oxygen from reacting with the metal, suppressing oxidation by up to a trillion-fold. Beyond explaining why gold jewelry stays bright for generations, the finding could help scientists create more powerful gold-based catalysts for manufacturing and clean energy. Read more ›

Yale scientists discovered two neuron surface proteins that appear to help spread the toxic protein linked to Parkinson’s disease. Blocking these proteins in mice dramatically reduced disease progression, offering a potential new target for future therapies. Read more ›
