17-Mar-2009 Controlling heat key to hybrid performance
Advanced hybrid-electric vehicles are poised to transform the auto market. But excess heat can sap hybrids' advantages. Researchers in NREL's Advanced Electronics Laboratory are exploring every layer of hybrid technology to reduce heat and dramatically improve performance and efficiency while reducing costs.
24-Feb-2009 How 10 trillion bits per square inch assemble themselves perfectly
Two chemically different polymers linked together to form self-assembling block copolymers can have the potential to vastly improve the properties and manufacturing processes of nanostructured materials. Using crystal structures as a template, researchers at Berkeley Lab and the University of Massachusetts Amherst have created perfect arrays of nanoscopic block-copolymer domains, packing 10 trillion bits to the square inch and extending over several square centimeters.
5-Feb-2009 The secrets of Darwin's dinobird
For centuries, the field of archaeology has depended on what's visible to the naked eye. Now, researchers are revealing what lies beneath the surface of a key evolutionary fossil, Darwin's "dinobird."
8-Jan-2009 A better way to make nanotubes
A doughnut-shaped molecule synthesized by Berkeley Lab scientists could enable the targeted development of carbon nanotubes, which hold promise for faster electronic devices and other advanced technologies.
6-Oct-2008 Bright light/dark matter: Free-electron lasers enter the realm of particle physics
While two accelerators have been operating at Jefferson Lab for more than a decade, only one was known for its research probing the particles that make up our universe. But things have changed. A particle physics experiment recently performed with Jefferson Lab's Free-Electron Laser, powered by the lesser-known and smaller accelerator, has had its results published in Physical Review Letters.
23-Sep-2008 BOSS: the Baryon Oscillation Spectroscopic Survey
One of the most crucial components of the new program of the Sloan Digital Sky Survey and its 2.5 m, wide-field telescope in New Mexico is a unique kind of dark-energy probe called BOSS, the Baryon Oscillation Spectroscopic Survey, led by Berkeley Lab physicists.
27-Aug-2008 Hope for those with Parkinson's
A Department of Energy program that opens some of the world's most powerful computers to researchers around the globe has generated a promising lead for a Parkinson's disease treatment.
9-Jul-2008 Powering the cars of the future
When you pull up to a filling station in the future, just what will you be "filling up" with? Will you recharge your batteries from an electrical outlet, pump in fuel made from scrap wood or grass, or perhaps feed your fuel cell with hydrogen? Researchers at the US Department of Energy are working on all of these options to power our cars in cleaner, practical, and cost competitive ways.
23-Jun-2008 Nuclear power option for developing nations gaining steam
Global energy demand is forecast to be 50 percent higher in 2030 than it is today and according to the International Energy Agency, seventy percent of this growth is expected to come from developing countries.
The question is: what will provide the additional energy?
10-Jun-2008 US Secretary of Energy concludes productive G8+3 Energy Ministerial Meeting in Japan
US Secretary of Energy Samuel W. Bodman today concluded his weekend visit to Aomori, Japan where he participated in the Five-Country and the Group of Eight, China, India and Korea Energy Ministerial meetings hosted by Japan's Minister of Economy, Trade and Industry Akira Amari. While in Japan, the Secretary met with ministers and other high-level government officials from G8 countries, China, India and Korea to discuss ways to enhance global energy security, while simultaneously combating global climate change.
3-Apr-2008 DOE technology monitors CO2 injection in Australian gas field
Australia has launched the first carbon sequestration project in the southern hemisphere with the help of technology developed by researchers at the US Department of Energy. The Otway Basin Pilot Project will inject and monitor carbon dioxide in a depleted gas field in southeastern Australia to demonstrate the feasibility of storing the greenhouse gas in the Waarre Formation of the Otway Basin, and similar formations worldwide, to fight global climate change.
27-Dec-2007 PNNL's Richard Smith named to prestigious Scientific American 50 list of outstanding leaders
Richard D. Smith, a Battelle Fellow at the Department of Energy's Pacific Northwest National Laboratory, has been named one of 50 outstanding leaders in the 2007 Scientific American 50 -- an annual list of 50 key contributors in science and technology. Smith shared the honor for creating a new approach to neurological diagnostics with Desmond Smith of UCLA's David Geffen School of Medicine.
27-Dec-2007 DOE to invest more than $5M for concentrating solar power
US Department of Energy Assistant Secretary for Energy Efficiency and Renewable Energy Alexander Karsner today announced DOE will invest $5.2 million in funding to support the development of low-cost Concentrating Solar Power.
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
