A cannabis-derived ingredient commonly found in sleep gummies may be more habit-forming than previously thought, with new research showing that repeated exposure caused tolerance and withdrawal symptoms in mice.…

Rebooting the gut microbiome with bacteria from youth may help stop aging-related liver damage and even prevent liver cancer, according to new research in mice.…

Researchers have developed a stem cell-based model of the human intestine that may transform how new IBD treatments are discovered. After testing thousands of compounds, they identified glycyrrhizin — a natural substance found in black licorice — as a…

Scientists have developed a breakthrough injectable biomaterial that travels through the bloodstream to repair damaged tissue from within, reducing inflammation and jumpstarting healing.…

A new study suggests a surprisingly simple compound could help fight Alzheimer’s disease. Researchers found that arginine—an inexpensive amino acid already considered safe—can reduce the buildup of toxic amyloid proteins in the brain, a hallmark of the…

Researchers have identified a new potential weapon against Alzheimer’s: blocking a protein called PTP1B. In mice, this approach boosted memory and helped brain immune cells clear harmful plaque buildup.…

Scientists have identified two specific types of brain cells that behave differently in people with depression, offering a clearer picture of what is happening inside the brain.…

Researchers have found a way to make cancer-killing immune cells more powerful and precise. By adding specific signaling components, they boosted the cells’ readiness to attack tumors.…
