Meditation is widely praised for its mental health benefits, but new research shows that it can also produce unexpected side effects for some people—from anxiety and dissociation to functional impairment. Psychologist Nicholas Van Dam and his team found that nearly 60% of meditators experienced some kind of effect, and about a third found them distressing....

Most U.S. adults don’t realize alcohol raises cancer risk, and drinkers themselves are the least aware. Scientists say targeting these misbeliefs could significantly reduce alcohol-related cancer deaths....

Scientists have shown that brain connectivity patterns can predict mental functions across the entire brain. Each region has a unique “connectivity fingerprint” tied to its role in cognition, from language to memory. The strongest links were found in higher-level thinking skills that take years to develop. This work lays the groundwork for comparing healthy and disordered brains....

USC researchers built artificial neurons that replicate real brain processes using ion-based diffusive memristors. These devices emulate how neurons use chemicals to transmit and process signals, offering massive energy and size advantages. The technology may enable brain-like, hardware-based learning systems. It could transform AI into something closer to natural intelligence....

A new copper-magnesium-iron catalyst transforms CO2 into CO at low temperatures with record-breaking efficiency and stability. The discovery paves the way for affordable, scalable production of carbon-neutral synthetic fuels....

Researchers discovered fossil evidence showing that spionid worms, parasites of modern oysters, were already infecting bivalves 480 million years ago. High-resolution scans revealed their distinctive question mark-shaped burrows. The finding highlights a parasitic behavior that has remained unchanged for nearly half a billion years....

Researchers discovered how rabies virus exerts massive control over host cells with very few genes. A key viral protein changes shape and binds RNA, allowing it to infiltrate different cellular systems. This adaptability could explain the power of other deadly viruses, including Nipah and Ebola. The breakthrough may lead to next-generation antivirals or vaccines....

Scientists discovered 6-million-year-old ice in Antarctica, offering the oldest direct record of Earth’s ancient atmosphere and climate. The finding reveals a dramatic cooling trend and promises insights into greenhouse gas changes over millions of years....

Engineers at the University of Delaware have uncovered a way to bridge magnetism and electricity through magnons—tiny waves that carry information without electrical current. These magnetic waves can generate measurable electric signals within antiferromagnetic materials, offering a possible foundation for computer chips that operate faster and use less power....
