Cataloguing underground waterways, some of which extend for thousands of miles, has always been difficult—but scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory, with colleagues from the University of Illinois at Chicago and the International Atomic Energy Agency, are mapping them with some unusual equipment: lasers and a rare isotope.

Multilayer Laue lenses (MLLs) developed at the U.S. Department of Energy Office of Science’s Advanced Photon Source (APS) focus high-energy x-rays so tightly they can detect objects as small as 16 nanometers in size, and are in principle capable of focusing well below 10 nanometers

The AutoTram, which uses an innovative charging system to allow the most charges in the fastest amount of time, is a result of a series of experiments about the best way to power public transit. Is it a bus?

Hydrogen is a clean fuel, but making it usually takes fossil fuels, until now: A new discovery allows hungry bacteria to eat dirty water to make the fuel. Hydrogen has potential as a clean-burning fuel. It leaves behind only water as it burns

From Paris to New York, Tokyo to San Francisco, developers from around the world turned out for Foursquare's global hackathon this past weekend. The aim? Like any good hackathon, to seed innovations in a round-the-clock binge of hacking and 5-Hour Energy

The toxic gas extraction isn't going away any time soon, but a new company has developed an enzyme that cleans up at least one of the poisonous problems of the process. There's no denying that hydraulic fracturing ("fracking") is a dirty business. The process can pollute groundwater with toxic chemicals, potentially cause earthquakes, and release methane (a potent greenhouse gas) into the atmosphere.

(PhysOrg.com) -- Ferromagnetic materials are key ingredients in vast arrays of technologies including wind turbines, computer hard-disks, credit card readers, and many more. Typically these magnets operate in moderate environments. But exposing a magnetic material to high heat or compressive stress usually destroys its magnetism because high temperatures and high compression induce agitation and mobility of unpaired electrons ("atomic compass"), destroying the correlated arrangement of atomic compasses across the solid needed to generate, or detect, magnetic fields

Coming to a city near you soon: By adding giant flywheels to subway systems, cities are able to harness the power created by thousands of braking trains, using it to accelerate other trains or feeding it back into the grid. Every time a train starts and stops, it draws or dissipates several megawatts of energy, enough to power more than a thousand homes. This happens thousands of time per day, every day, in commuter rail systems across the country.

Freshlist--one of the most exciting projects to come out of the 24-hour Cleanweb Hackathon--connects sellers and buyers of local produce so nothing goes to waste.

A leading agriculture company is about to put the United States on the map with the world's biggest carbon sequestration projects.

On the verge of losing the business, CEO Tom Walter looked to young employees to turn his business around, and then helped them fund their own. In the last 6 years, Illinois-based Tasty Catering has undergone a revolution—a revolution that not only saved it from closing its doors, but also turned the company into a local incubator for young entrepreneurs

Want to get in on the action at fashion week? Here's a look at how some small businesses are using the event to market their brands

TOKYO (Reuters) - Radioactive material released into the sea in the Fukushima nuclear power plant crisis is more than triple the amount estimated by plant operator Tokyo Electric Power Co, Japanese researchers say. Japan's biggest utility estimated around 4,720 trillion becquerels of cesium-137 and iodine-131 was released into the Pacific Ocean between March 21 and April 30, but researchers at the Japan Atomic Energy Agency (JAEA) put the amount 15,000 trillion becquerels, or terabecquerels.

Natural gas might burn much cleaner than coal, but getting it has its problems: leaky pipes. And those leaks spray gasses that are worse for the climate than carbon. Natural gas is a hot energy commodity right now, with new drilling techniques, low prices, a big domestic supply in the U.S., and the support of people like T

Whether you have a few company cars or a fleet of several dozen trucks, you can save money on fuel by making minor changes to your operations and driving.
