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 can help…

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 Toxoplasma…

Even Antarctica’s toughest native insect can’t escape the reach of plastic pollution. Scientists have discovered that Belgica antarctica — a tiny, rice-sized midge and the southernmost insect on Earth — is already ingesting microplastics in the wild. While…

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 moving “dancing…

The old saying "you are what you eat" suggests that our food choices determine our health and longevity. Now, a study published in the journal Science Advances has put some specifics on it by estimating ...

A new analysis from the 2015 Pelotas Birth Cohort suggests that dietary patterns at just 2 years of age are associated with cognitive performance at ages 6 and 7. The findings add to growing global evidence ...

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 was linked…

In two new studies on 28,000 individuals, researchers are able to show that genetic variants in 11 regions of the human genome have a clear influence on which bacteria are in the gut and what they do ...

How you take probiotics can affect their impact on the brain. A study from Örebro University points to new possibilities for personalized approaches, depending on whether the primary aim is, for example, ...

Clinical neurophysiology examinations include electroencephalography, sleep and vigilance studies, as well as nerve conduction recordings. Interpretation of these recordings is largely taught during clinical ...

Researchers from the NeuroAD group (Neuropathology of Alzheimer's Disease) within the Department of Cell Biology, Genetics and Physiology at the University of Málaga, also affiliated with IBIMA–BIONAND ...

Presbycusis is a prevalent form of age-related hearing loss that also hinders speech recognition. While scientists have linked hearing loss to an increased risk of cognitive decline, the biological "bridge" ...

The gene most strongly correlated with Alzheimer's disease also boosts seizure activity by decreasing levels of ion pumps and energy-producing enzymes in neurons, a new study by researchers at the University ...

Moringa powder capsules have been recalled as a CDC and FDA investigation links the capsules to a new form of salmonella outbreak that the CDC calls "unusual and highly concerning."

Shaili Gupta often sees patients who consult chatbots like ChatGPT for health advice. She finds that some of her patients are much more informed about health-related issues and have follow-up questions ...

About 170,000 people in England every year spend their final days in pain, distress or without vital support that should be available to everyone at the end of life. These are the findings of the first ...

As cash transfer programs expand across the United States, critics often warn that giving people money could spark reckless behavior, leading to injuries or even deaths. But a sweeping 11-year analysis of Alaska’s long-running Permanent Fund Dividend program…

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 from just…

Another cold snap is approaching. Some people deal with it by taking an invigorating walk outside, while others hibernate with a cozy blanket and biscuits. But one thing seems to be common when temperatures ...

An Ice Age double burial in Italy has yielded a stunning genetic revelation. DNA from a mother and daughter who lived over 12,000 years ago shows that the younger had a rare inherited growth disorder, confirmed through mutations in a key bone-growth gene.…

Researchers have identified two brain receptors that help the brain clear away amyloid beta, a hallmark of Alzheimer’s disease. By stimulating these receptors in mice, scientists increased levels of a natural amyloid-breaking enzyme, reduced buildup in the…
