The Moth Hunters

Bathed in violet light, two men search the white expanse of cloth, oblivious to their surroundings. Disoriented insects of various shapes and sizes swoop around the men’s heads. Many of the insects eventually land on the sheet. With a deft motion, one of the men captures a specimen and examines the vial in which a pale-colored moth flutters.

Rock Tasting at Biosphere 2

With a mischievous grin and gleaming dark eyes, Dr. Dragos Zaharescu raises a small spatula to his lips and tastes. At his feet are four containers, each filled with a different type of ground rock—granite, basalt, rhyolite or schist.

Similar storms are observed in the Sahara desert, across the Arabian Peninsula, in Kuwait, and regions of North America. Dust storms from Africa dumped 50 million metric tons of dust on the state of Florida in the summer of 2013.
