A Winston-Salem business is starting a residential composting program this summer.

The apple trees are heading for full blossom in Michigan after a disastrous 2012 crop, when only 15 percent of the apples survived. But this year's harvest is expected to rebound.

The defenders of Africa's rhinos are battling a well-financed and well-informed enemy. Poachers clear $40,000 or more for a single rhino horn. They have cash for the latest weaponry and to pay for inside information from some of the very people whose job it is to protect the rhinos.

By the end of the century, ocean levels could rise by 2 or 3 feet. That's enough to flood the colonists' first settlement at Jamestown, Va. And it's putting pressure on archaeologists to get as many artifacts out of the ground as quickly as possible — before it's too late.

Demand for rhino horn, used in traditional Chinese medicine, is fueling a slaughter of the animals in Africa. In Vietnam, the sought-after commodity is fetching prices as high as $1,400 an ounce, or about the price of gold. There, some believe ground horn can cure everything from hangovers to cancer.

Since 1958, researchers have been measuring the amount of carbon dioxide in the atmosphere at the Mauna Loa Observatory. The remote outpost has just reported a carbon dioxide level of 400 parts per million — the highest it has climbed in the modern age.

Taking a page from the playbook of decades past, college students are once again pressuring schools to pull investment funding from specific sectors. This time it's big oil and coal companies. But these campaigns have effects beyond the university — they're launching a new generation of activists.

Royal Dutch Shell is pushing ahead with plans for the world's deepest offshore oil and gas production facility. It will be nearly two miles beneath the surface of the Gulf of Mexico, off the coast of Louisiana. It is testing the bounds of the oil and gas industry's capability to drill ever deeper.

North Carolina Lawmakers continue to debate proposed fracking legislation. A panel discussion Thursday night in Winston-Salem will take a closer look at the issues surrounding this natural gas drilling method.

Science education standards, issued in April, recommend teaching climate change for the first time. But one nonprofit says kids aren't learning enough, soon enough, about how their world will change in the coming decades. The group aims to remedy this with presentations in schools nationwide.
