Leaping Lemurs

Duke Lemur Center preserves and protects lemurs, unique primates that are the ancient relatives of monkeys, apes and humans. Lemurs evolved in isolation on Madagascar, but are threatened as the island's human population grows. Researchers study behavior, genomics, physiology and conservation biology in order to preserve the existence of lemurs worldwide.

New Use for Coal Ash

Coal ash is a byproduct of burning coal to generate electricity and is often stored in ponds near power plants. But when coal ash spilled out of a Duke Energy storage pond into the Dan River, it focused attention on the problem of storing coal ash. While some is currently used in concrete, NC A&T Researchers are finding a new use for coal ash as a super strong building material.
