Scientists starved worms — then discovered the switch that controls aging

Scientists have discovered that starving and then refeeding worms can reveal surprising secrets about aging. When a specific gene (called TFEB) is missing, these worms don’t bounce back from fasting—they instead enter a state that looks a lot like aging in humans, with signs of stress and cell damage. This research gives scientists a simple but powerful way to study how aging begins—and how it might be stopped. Even more intriguing, the same process might help explain how some cancer cells survive treatment by going into a kind of sleep mode.
