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 obesity drugs.
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 cells so they continue encouraging anti-inflammatory immune responses even after the compound is gone. In mice, this effect boosted production of the immune-calming molecule IL-10 and reduced the severity of colitis-like disease.
Scientists have identified exceptionally rare soft tissue preserved in a 450-million-year-old crinoid fossil, more than 200 million years older than the first dinosaurs. Its delicate tube feet offer a remarkable new window into how some of Earth’s earliest reef animals lived, fed, and evolved.
