]]> Everybody gets older, although not everyone ages in the same way. For many people, late life includes a deterioration of health brought on by age-related disease.

]]> Even when it’s not apparent, cells in our tissues and organs are constantly on the move. In fact, the ability of cells to get where they need to go is essential to our health and survival. Skin cells migrate to heal wounds. Immune system cells migrate to fight infections. “Every day, you look at your body and it’s not changing much,” said Peter Devreotes, a professor of cell biology at the Johns...

]]> In 2008, while the medical resident Sam Behjati was doing his usual rounds in a hospital maternity ward, a colleague urgently pulled him into a patient’s room, where he saw a mother beaming with joy and swaddling a perfectly healthy newborn. Behjati’s jaw dropped. Only a few months earlier, doctors had given this mother the devastating news that a routine prenatal test — which had analyzed a...

]]> When I first met the immunology researcher James P. Allison in 2014, he was just becoming an icon. Columbia University had brought him to its campus to present him with the Louisa Gross Horwitz Prize for the new type of cancer therapy he had developed.
