They have done in five months what normally times four years, in a process that should be a model for how it's done.

Using LED lighting instead of traditional high pressure sodium lights to grow tomatoes in greenhouses during the winter could cut costs and boost local food production.

Ever wondered what it's like to be eaten by a grizzly bear? Probably not... Except maybe in a nightmare. In any case, it's now possible to see (if not feel) what it's like from the safety of your home.

In 2011, the first full year with the current crop of plug-ins on the market, fewer than 20,000 were sold.

Sitting in the middle of the vast space, he demonstrates the traditional art of African weaving

Classic Mid-Century modern designs are back at ICFF.

The New York Times' Elisabeth Rosenthal reports that New York spends "$10 million annually to send 100,000 tons of plastic bags that are tossed in the general trash to landfills in South Carolina, Ohio and Pennsylvania."

The National Highway Traffic Safety Administration (NHTSA) has decided to test plug-in vehicles separately from gas and gas-electric hybrid versions of the same models.

The New Yorker's Elizabeth Kolbert explains why the Keystone XL pipeline must be a line in the sand for a livable future.

U.S. scientists have developed what they say is the first integrated nanosystem capable of replicating the process of photosynthesis, a sort of “artificial forest” that could one day lead to the production of hydrogen that could be used to power fuel cells. Composed of nanowire structures — including silicon “trunks” and titanium oxide “branches” — the system mimics the role played by chloroplasts in promoting photosynthesis in green plants. By assembling the “trees” in a dense array, resembling a miniature forest, the network lowers sunlight reflection and provides more surface area for hydrogen-producing reactions, the scientists say. “We’ve integrated our nanowire nanoscale heterostructure into a functional system that mimics the integration in chloroplasts and provides a conceptual blueprint for better solar-to-fuel conversion efficiencies in the future,” said Peidong Yang, a chemist with the Lawrence Berkeley National Laboratory and co-author of the study, published in the journal NANO Letters. The lab of Daniel Nocera at Harvard University is doing related research into so-called artificial leaves. Article appearing courtesy Yale Environment 360.
