Aquaponics

Aquaponics is a system for farming fish and plants together in a mutually beneficial cycle. Fish produce waste that is a fertilizer for plants while plants suck up the nutrients as they purify the water. The system is efficient and environmentally friendly. A farm in Norwood, NC is pioneering the technique.

Acorns Count

The acorn is not only a symbol of fall, but the nuts are a baseline indicator of the current and future health of the forest ecosystem. U.S. Forest Service researchers studying acorns find a bounty of acorns indicates healthy trees and a plentiful food supply for the creatures that form the base of the forest food chain.

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.

Reef Life

Researchers discover natural oyster reefs grow fast enough to keep up with the projected rise in sea levels, suggesting oyster reefs could be used for storm protection and erosion control, all the while doing what oyster reefs naturally do, which is filter the water and provide a habitat for fish.

Life on the Rocks

North Carolina's rocky offshore reefs provide nurseries for juvenile fish, foraging grounds, hiding places, and spawning grounds. Research into offshore wind energy has prompted a new look at the health and diversity of life on the rocky reefs off the NC coast, where wind turbines could be located.

Greening the Golf Course

The restoration of historic Pinehurst #2 golf course, site of the 2014 U.S. Open, to its original design is a model of golf going green. The course, filled with native plants needing less care, matches the Sandhills environment, using less water and chemicals. The USGA and PGA say it's a model of golf going back to nature.
