A few minutes of sprinting may reshape the bloodstream far more dramatically than a much longer moderate workout. Six 30-second sprints altered nearly a quarter of the blood proteins measured and more than 200 metabolites, while 90 minutes of ...

A hormone already known for curbing appetite and supporting weight loss may have a surprising second job: protecting the liver from inflammation and scarring. Researchers at McMaster University found that GDF15 activates a previously unknown brain-to ...

AI may be able to predict how strongly someone will respond to a vaccine before they receive it. By analyzing antibody patterns in more than 4,000 people, researchers found signs of "immune readiness" that helped distinguish strong responders from .. ...

People who participated in colorectal cancer screening had a 43% lower risk of dying from the disease, according to long-term data from more than 376,000 people in Sweden. The findings suggest that completing a simple at-home screening test could ...

A compound made when gut bacteria break down dietary fiber may do more than briefly calm inflammation--it could leave a lasting protective "memory" in the gut. Northwestern Medicine researchers found that butyrate can reprogram intestinal lining ...

Ozempic may work in the brain in almost the opposite way scientists expected, activating hunger-linked neurons that appear essential for sustaining fat loss. The surprising discovery in mice could reveal new targets for developing even more effective ...

Knee osteoarthritis can seriously affect mobility and quality of life, but its progression isn't completely out of your control. Exercise, stronger leg muscles, a healthier diet, and even modest weight loss can dramatically reduce stress on the knees ...

Specialized brain scans reveal that schizophrenia is linked to widespread loss of the synapses that connect brain cells, with the left side of the brain hit especially hard. The damage follows a surprisingly organized pattern tied to the brain's ...

More than 1,000 genetic switches behave differently in male and female immune cells, helping explain why women are much more vulnerable to autoimmune diseases such as lupus. Female immune systems appear genetically tuned for stronger inflammatory ...

Researchers have developed a new way to turn ordinary antibodies into tiny disease-fighting molecules that can work inside human cells, potentially opening new paths for treating Alzheimer's, Parkinson's, Huntington's disease, and motor neurone ...
