A surprising study suggests that chemicals introduced to protect the ozone layer may have unintentionally created a growing global pollution problem. Researchers found that refrigerants and certain anesthetic gases have generated more than 335,000 tonnes of trifluoroacetic acid (TFA), a highly persistent "forever chemical," that has been deposited across Earth's surface since 2000. The pollutant is now showing up everywhere from rainwater to remote Arctic ice, and scientists expect levels to keep rising.

The Democratic Socialists of America say they are fighting for “a government by, for, and of the working class.” Yet the organization’s membership and candidates consist largely of educated professionals. As of 2021, 80 percent of DSA members over 25 were college-educated, while 28 percent earned more than $100,000 a year (putting them in roughly […] 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 ›

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 ›

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 ›

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 ›

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.

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 ›

Researchers have discovered that the retina uses an unexpected communication network that lets separate visual pathways cooperate instead of working alone. A newly identified "commander" cell appears to coordinate this system, helping the eye detect faint details that might otherwise be missed. Read more ›

Dark matter may be far more complicated than scientists once believed. A new study suggests it could consist of at least two different kinds of particles that slowly separate over time, with heavier particles sinking toward the centers of galaxies and lighter ones drifting outward. This simple idea could explain several puzzling cosmic observations that have frustrated astronomers for years, from unusually diffuse dwarf galaxies to surprisingly dense dark matter... Read more ›

A new book claims AI has been built on a flawed assumption dating back to Alan Turing's famous 1950 paper. Peter J. Denning argues that the most important parts of human intelligence, including common sense, intuition, culture, and practical know-how, cannot be encoded into computers. He believes this makes true human-level AI impossible, regardless of how large language models become. Read more ›
