Scientists in California continuously infused the blood of young mice into old mice—and found that the old mice functioned as if they were young. What if something similar could be done in humans? It's not science fiction—it's called senolytics, and it's a major player in the quest for longevity. HOW DOES IT WORK—AND HOW FAR OFF IS IT? WHAT CAUSES OUR BODIES TO AGE?

Then she heard about apheresis—a costly treatment that patients are flying across the world for, even though there's no evidence it works. WHAT THE SCIENCE SAYS

The long COVID puzzle:

• Could the secret to long COVID lie in our blood vessels? • How do you know if you have long COVID? • How multiple COVID-19 infections can harm the body

WHAT DOES CANCER SMELL LIKE?

PHOTOGRAPH BY JOHNER IMAGES, GETTY IMAGES Dogs aren't the only creatures whose senses can register signs of human disease. Ants, rats, bees, and even tiny worms can be trained to detect markers of illness—from cancer to COVID-19 to tuberculosis. WHAT IT MEANS FOR YOU CANCER VACCINES ARE SHOWING PROMISE: This is how they would work. +
