Ecologist Suzanne Simard has shown how trees use a network of soil fungi to communicate their needs and aid neighboring plants. Now she’s warning that threats like clear-cutting and climate change could disrupt these critical networks.

Wildlife farming is being touted as a way to protect endangered species while providing food and boosting incomes in rural areas. But some conservation scientists argue that such practices fail to benefit beleaguered wildlife.

As the National Park Service marks its centennial this month, the parks are being celebrated for their natural beauty and priceless recreational opportunities. But they also provide a less recognized benefit: the parks serve as a living laboratory for critical scientific research.

The Rocky Flats Plant outside Denver was a key U.S. nuclear facility during the Cold War. Now, following a $7 billion cleanup, the government is preparing to open a wildlife refuge on the site to the public, amid warnings from some scientists that residual plutonium may still pose serious health risks.

By linking together networks of energy-efficient buildings, solar installations, and batteries, a growing number of companies in the U.S. and Europe are helping utilities reduce energy demand at peak hours and supply targeted areas with renewably generated electricity.

John Morales is part of a new breed of television weather forecasters seeking to educate viewers on climate change and the threat it poses. In South Florida, where sea level rise is already causing periodic flooding, he has a receptive audience.

Researchers are finding that kelp, eelgrass, and other vegetation can effectively absorb CO2 and reduce acidity in the ocean. Growing these plants in local waters, scientists say, could help mitigate the damaging impacts of acidification on marine life.
