A new light-based sensor can spot incredibly tiny amounts of cancer biomarkers in blood, raising the possibility of earlier and simpler cancer detection. The technology merges DNA nanotechnology, CRISPR, and quantum dots to generate a clear signal .. ...

A parasite that may already be hiding in your brain has a shocking survival trick: it can infect the very immune cells sent to destroy it. Yet most people never get sick, and new research from UVA Health reveals why. Scientists discovered that when . ...

Researchers have built a realistic human mini spinal cord in the lab and used it to simulate traumatic injury. The model reproduced key damage seen in real spinal cord injuries, including inflammation and scar formation. After treatment with fast ...

For years, compulsive behaviors have been viewed as bad habits stuck on autopilot. But new research in rats found the opposite: inflammation in a key decision-making brain region actually made behavior more deliberate, not more automatic. The change ...

A sweeping review of global research suggests that exercise--especially aerobic activities like running, swimming, and dancing--can be one of the most powerful ways to ease depression and anxiety. Across tens of thousands of people aged 10 to 90, ...

Researchers have uncovered the enzyme behind chromothripsis, a chaotic chromosome-shattering event seen in about one in four cancers. The enzyme, N4BP2, breaks apart DNA trapped in tiny cellular structures, unleashing a burst of genetic changes that ...

A major new study suggests that eating the Nordic way could help you live significantly longer--while also helping the planet. Researchers from Aarhus University found that people who closely followed the 2023 Nordic dietary guidelines had a 23% ...

A new Stanford study suggests math struggles may be about more than numbers. Children who had difficulty with math were less likely to adjust their thinking after making mistakes during number comparison tasks. Brain imaging showed weaker activity in ...

Researchers tracked more than 400 toddlers to see whether mRNA COVID-19 vaccination during or just before pregnancy was linked to autism or developmental delays. After detailed assessments of speech, motor skills, behavior, and social development, .. ...

Scientists have created the most detailed maps yet of how genes control one another inside the brains of people with Alzheimer's disease. Using a powerful new AI-based system called SIGNET, the team uncovered cause-and-effect relationships between .. ...
