Your morning coffee could one day help fight cancer

Scientists at Texas A&M are
turning an
everyday pick-me-up into a high-tech
medical switch. By combining caffeine with CRISPR gene editing, researchers have created a system that allows cells to be programmed in advance — and then activated simply by consuming a small dose of caffeine from coffee, chocolate, or soda. The approach, known as chemogenetics, lets scientists precisely turn gene-editing activity on and off inside targeted cells, including powerful immune T cells that can fight cancer.
