MIT neuroscientists have uncovered a surprising secret hidden in the adult brain: millions of "silent synapses," dormant connections that lie in wait until new learning calls them into action. Once thought to exist only in early development, these .. ...

Penn researchers have developed a smarter AI method for solving notoriously difficult inverse equations, which help scientists uncover hidden causes behind observable effects. By introducing "mollifier layers" that smooth noisy data, they've made ...

A forgotten fossil hidden inside a garden wall has turned out to be one of Australia's most remarkable prehistoric discoveries. Scientists have now identified the 240-million-year-old amphibian, Arenaerpeton supinatus, revealing an almost perfectly . ...

A short burst of immunotherapy before surgery is delivering surprisingly powerful results for a specific type of colorectal cancer. Patients in a UK-led trial who received just nine weeks of pembrolizumab prior to surgery have remained cancer-free .. ...

A major 10-year clinical trial is turning one of the world's most common knee surgeries on its head. Researchers found that trimming a damaged meniscus--a procedure long believed to relieve pain--offers no real benefit over placebo surgery. Even more ...

A chaotic sleep schedule in your 40s might be quietly setting the stage for heart trouble later. Researchers tracking thousands of people for over a decade found that those with highly inconsistent bedtimes--especially when they slept less than eight ...

Oak trees have a surprising trick to fight back against hungry caterpillars: they simply wait. When trees are heavily attacked one year, they delay leaf growth by just three days the next spring--long enough to leave newly hatched caterpillars with . ...

A scorching, airless world just 48 light-years away is offering scientists a rare glimpse into the geology of distant planets. Using the James Webb Space Telescope, researchers studied LHS 3844 b--a tidally locked "super-Earth" with a permanent ...

Creating complex molecules usually requires years of experience and countless decisions, but a new AI system is changing that. Synthegy lets chemists guide synthesis and reaction planning using simple language, while powerful algorithms generate and ...

A surprising genetic twist shows that boosting a seemingly ordinary "housekeeping" gene can dramatically improve fruit quality without any trade-offs. By increasing the activity of a tRNA-related gene in strawberries, researchers unlocked richer ...
