A major new study has uncovered important differences in how the brains of autistic children respond to human faces. Published in Nature Mental Health, the research is among the most extensive investigations yet into how face perception works in autism. Some autistic people tend to look at faces less frequently…
Around 66 million years ago, an asteroid struck Earth and brought the age of the dinosaurs to an end. The mass extinction that followed created opportunities for countless other animals to evolve and spread. Ants were among the groups that eventually became remarkably successful, and scientists have now identified a…
Scientists at McGill University have discovered a surprising ability in immune cells that could reshape our understanding of how the body develops lasting protection against infections. For years, researchers believed that tissue-resident memory T cells, specialized immune cells that remain in the body’s tissues after an infection and respond quickly…
Scientists have uncovered a surprising connection between the bacteria living in the human gut and the speed at which the body ages. Researchers at the University of Hawaiʻi at Mānoa found that certain gut microbes are associated with slower biological aging, while others are linked to faster aging. The study,…
Low testosterone can contribute to several health problems, and an unhealthy diet may make some of those risks even worse. One major concern is metabolic dysfunction-associated steatotic liver disease (MASLD), a condition that affects approximately 40% of adult men worldwide and has become a significant global health issue. Fatty liver,…
Medications are designed to treat diseases and relieve symptoms, but some can also produce unintended effects that put patients at risk. While side effects are common with many treatments, researchers have identified a particularly concerning possibility involving drugs used to control inflammation. Scientists at the Norwegian University of Science and…
Astronomers have discovered surprising evidence that a scorching planet covered in molten rock may be protected by a reflective layer of clouds that acts like a giant sunscreen. Scientists previously believed that the planet’s extreme conditions would make it nearly impossible for an atmosphere to survive, but new observations suggest…
Scientists have created one of the largest and most detailed simulations of the early universe ever developed, offering a remarkable new way to explore how the cosmos evolved after the Big Bang.
