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.

Straw Into Gold: New Way to Retrieve CO2 From Air and Recycle It Into Useful Products

Turning an undesirable substance into something valuable seems like the plot of an old fable, but UC Berkeley researchers Chris Chang and Omar Yaghi may have done just that. Their invention, covalent organic frameworks, or COFs, can transform atmospheric carbon dioxide into a useful building block for biodegradable plastics, fuel, and more.

Chang likens COFs to TinkerToys, though at a nano scale. They consist of strings of carbon crystals that are special in their unique porosity, as they can be custom tailored to capture the chemical of choice.
