New Material Could Vastly Improve Carbon Capture To capture the carbon dioxide generated by coal plants, chemical companies like Dow Chemical Co. and energy giants like Alstom SA have been betting big on liquid solvents like amine, a corrosive derivative of ammonia that has a thirst for binding with CO2.Problem is, once the two are bound, they never want to part.

Are Endangered Species Being Sacrificed for Coal in Appalachia? The last ice age turned the Appalachians into North America's Noah's Ark.The mountain peaks provided a last green refuge above the glaciers, drawing species from across the eastern half of continent. Some 10,000 years later, many have stayed, and the mountains are home to one of the highest concentrations of biodiversity -- from flying squirrels to freshwater mussels -- in the country. Just last month, biologists stumbled across an entire new genus of salamanders in Southern Appalachia, the first new vertebrate genus discovered in the United States in 50 years.

Biotech's Plans to Sustain Agriculture (preview) If environmental and economic sustainability is ultimately a matter of balancing the human race’s consumption and productivity, then the agricultural industry leans heavily on both sides of that scale. Its drain on the earth’s resources is enormous: it claims 70 percent of all freshwater taken by our species and more than 40 percent of the planet’s solid surface (nearly all the arable land), with attendant casualties in bio­diversity. Yet modern agriculture is also the only reason we can produce enough food to nourish our population of 6.8 billion--a number slated to reach more than nine billion by midcentury. Keeping up with that steeply rising demand thus defines the challenge of sustain­ability not only for agriculture but for humanity. Agriculture depends on many technologies, but bio­technology might be the most influential among them. To find out how the industry perceives its prospects for raising both global crop productivity and sustainability, con­tributing editor John Rennie spoke with representatives of four leading agricultural biotechnology companies. What follows here is an abridged version of their edited con­versation. --The Editors [More] rss.sciam.com |
