Scientists have successfully created synthetic crystals whose structures and properties mimic those of naturally occurring biominerals such as seashells. The findings, published in the journal Nature Materials, could be an important step in the development of high-performance materials, which could be manufactured under environmentally-friendly conditions
Measuring the emission of greenhouse gases from croplands should take into account the crops themselves, according to new research.
When many people think of industrial chemicals, they think of those scary-looking yellow drums, containing unknown but almost certainly hazardous goo. A new industry initiative, though hopes to change that by giving consumers more information on the chemicals they use every day.

In an attempt to mimic the photosynthetic systems found in plants and some bacteria, scientists have taken a step toward developing an artificial light-harvesting system (LHS) that meets one of the crucial requirements for such systems: an approximately 100 percent energy transfer efficiency.
Here’s one way that old-fashioned newsprint beats the Internet: Tulane University scientists have discovered a novel bacterial strain, dubbed “TU-103,” that can use paper to produce butanol, a biofuel that can serve as a substitute for gasoline.
Billions of people owe their lives to nitrogen fertilizers – a pillar of the fabled Green Revolution in agriculture that averted global famine in the 20th century – but few are aware that nitrogen pollution from fertilizers and other sources has become a major environmental problem that threatens human health and welfare in multiple ways.
New Department of Energy efficiency standards will cut the energy use of most new refrigerators by 25 percent and help save consumers money, create jobs, reduce pollution and spur innovation and investment.
Globally, irrigation increases agricultural productivity by an amount roughly equivalent to the entire agricultural output of the U.S., according to a new University of Wisconsin-Madison study.
Two years ago, Florida State University senior Sandy Simmons went to a college housing conference and got a big idea: recycled bike rentals for students — on the cheap.
The U.S. Environmental Protection Agency recently announced that the Great Lakes Restoration Initiative is setting aside approximately $6 million for federal agencies to sign up unemployed workers to implement restoration projects in federally-protected areas, on tribal lands and in Areas of Concern in the Great Lakes basin.
Imagine being able to get the equivalent of 70 miles per gallon in your car, keep your home cool and power your computer – all from sewage. Thanks to technology developed by University of California-Irvine’s National Fuel Cell Research Center and partners, that’s now possible.
Gotham Greens, a hydroponics greenhouse facility, sits on a warehouse rooftop and brings new meaning to the phrase "locally grown" – especially atop a 15,000-square-foot manufacturing building in Greenpoint, Brooklyn.

Except for the few temperate regions on the West Coast, air conditioners are now standard equipment in most homes, especially in those newly constructed.
The explosive growth of cities worldwide over the next two decades poses significant risks to people and the global environment, according to a meta-analysis published today in Plos One.
A novel microscopy method at the Department of Energy’s Oak Ridge National Laboratory is helping scientists probe the reactions that limit widespread deployment of fuel cell technologies.
The NASA Ames Sustainability Base in Moffett Field, Calif., has won two awards for sustainability and innovation.
Using government-supplied measurements, the researchers found concentrations of fine particles in Ulaanbaatar’s air were more than seven times the level considered safe by the World Health Organization
A report forecasts that the EV cybersecurity market will increase from just $26 million in 2011 to $144 million by 2015, with a cumulative investment of $432 million during that period.
Researchers at the University of California, Riverside along with their research partners received a $1.2 million grant from the Department of Energy to study and evaluate technologies that provide feedback to drivers so they can cut harmful emissions and reduce fuel use by up to 30 percent.
Undergraduate researcher Safatul Islam is a member of a team in the College of Optical Sciences investigating organic photovoltaics, which can lead to improved electronics.
