The Secret of the Sea Nomads

The Bajau people, commonly known as “sea nomads,” live in coastal regions of the Philippines, Malaysia, and Indonesia. They spend some 60 percent of their working hours in the sea, foraging for food at depths of up to 230 feet below the surface. Bajau divers are known to hold their breath for several minutes at a time.

How do they do it? Researchers think they have found the key: larger spleens.

Findings like these are a reminder that humans, like all animals, are products of evolution.

Q&A: Rebecca Skloot on Seeing “Henrietta Lacks” Come To Life Onscreen

When Rebecca Skloot was 16 years old, her biology teacher wrote a name on the blackboard: “Henrietta Lacks.” He explained that Lacks was a black woman whose surgeon had extracted cells from her tumor in 1951. They turned out to be the first human cells to survive indefinitely in a laboratory. Billions of so-called HeLa cells lived in labs around the world and had helped produce treatments for leukemia, influenza, Parkinson’s disease, and many other ailments.
