Chronic inflammation may be quietly reshaping the colon and making it more vulnerable to early-onset colorectal cancer. Scientists found that colon tissue in younger patients was stiffer, even in areas that appeared healthy, suggesting these changes ...

Aging immune cells may be sabotaging the body from within. Researchers found that macrophages produce a protein that locks them into a chronic inflammatory state, making infections like sepsis more deadly in older adults. Turning off this signal ...

People with spinal cord injuries often lose movement even though their brains still send the right signals. Researchers tested whether EEG brain scans could capture those signals and reroute them to spinal stimulators. The system can detect when a .. ...

A large, decades-long study suggests that signs of ADHD in childhood may have consequences that extend well beyond school and behavior. Researchers followed nearly 11,000 people from childhood into midlife and found that those with strong ADHD traits ...

Chemotherapy's gut damage turns out to have a surprising upside. By changing nutrient availability in the intestine, it alters gut bacteria and increases levels of a microbial molecule that travels to the bone marrow. This signal reshapes immune cell ...

Alzheimer's may be driven far more by genetics than previously thought, with one gene playing an outsized role. Researchers found that up to nine in ten cases could be linked to the APOE gene -- even including a common version once considered neutral ...

In Guatemala's Western Highlands, researchers found that the drinking water people trust most may actually be the riskiest. Bottled water from refillable jugs--seen as the safest choice--was frequently contaminated with harmful bacteria, while ...

New research suggests that auditory hallucinations in schizophrenia may come from a brain glitch that confuses inner thoughts for external voices. Normally, the brain predicts the sound of its own inner speech and tones down its response. But in ...

Researchers have identified a promising new weapon against triple-negative breast cancer, one of the most aggressive forms of the disease. An experimental antibody targets a protein that fuels tumor growth and shuts down immune defenses, effectively ...

Type 2 diabetes becomes more dangerous to the heart the longer a person has it. Researchers found that after several years, red blood cells can begin interfering with healthy blood vessel function. This harmful shift was not present in newly ...
