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.
7-Nov-2008 Solo sparkle: Electron give-and-take lets molecules shine individually on camera
A single fluorescent molecule flashing as it gains or loses its electron has made the microscopic spotlight. Watching a whole gaggle of these molecules, they appear to work synchronously, but a new close-up view reveals mavericks that shine when they seemingly shouldn't. The work sets the stage for a better understanding of the underlying principles of certain reactions common to biofuel production.
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 INL engineer's long-term nuclear fuel research pays off
Science doesn't happen overnight, and Idaho National Laboratory Fellow Dave Petti knows that better than many. His research has required a long-term commitment from him and his colleagues -- one that is starting to pay off as the products of their work are breaking barriers and receiving national consideration.
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.
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?
7-May-2008 Dark Energy's 10th Anniversary, Part III
The third in a three-part history celebrating the 10th anniversary of the discovery of dark energy, recounting the Supernova Cosmology Project's pioneering efforts to overcome skepticism and prove that indeed it was possible to measure the expansion rate of the universe by using Type Ia supernovae as standard candles. The unexpected results stunned astronomers and physicists alike.

2-May-2008 'Skinny' pions sail through nucleus
A recent Jefferson Lab experiment may have demonstrated the onset of color transparency for pions, a necessary ingredient for interpreting related experimental results in nuclear and particle physics. The experiment was performed in Jefferson Lab's Experimental Hall C.
25-Apr-2008 DOE and DOD launch ENERGY STAR Operation Change Out
US Secretary of Energy Samuel W. Bodman on Earth Day launched a joint Department of Energy and Defense campaign to challenge military bases nationwide to change their incandescent light bulbs to energy efficient compact fluorescent light bulbs in on-base housing. The ENERGY STAR campaign, called Operation Change Out, will help bases across the country increase energy efficiency, save money and reduce carbon dioxide emissions.
28-Mar-2008 US Department of Energy to provide up to $2.4M to advance solar energy in 12 US cities
US Department of Energy Secretary Samuel W. Bodman today announced that DOE will make available up to $2.4 million to 12 cities across the country selected as Solar America Cities, chosen for their commitment and comprehensive approach to the deployment of solar technologies and the development of sustainable solar infrastructures. These projects further President Bush's Solar America Initiative, which aims to make electricity from solar photovoltaics cost-competitive with conventional electricity by 2015.
29-Feb-2008 US Department of Energy welcomes the UK as 21st member of the Global Nuclear Energy Partnership
The US Department of Energy today welcomed the United Kingdom as the Global Nuclear Energy Partnership's twenty-first partner. GNEP, a voluntary international partnership, aims to safely and securely expand nuclear power worldwide while responsibly managing nuclear waste and reducing proliferation risks. US Energy Secretary Samuel Bodman met with UK Secretary of State for Business, Enterprise and Regulatory Reform, Rt. Hon. John Hutton prior to the UK signing the GNEP Statement of Principles in Washington, DC.
31-Jan-2008 Spin in the neutron
Physicists were in a whirl after measurements in the '80s revealed that the spins of the individual building blocks of the proton don't add up to the proton's actual spin. The so-called "proton spin crisis" spurred efforts to pin down where protons -- and neutrons -- get their spin. Pioneering measurements in Jefferson Lab's Hall A have opened the door for measuring some suspected sources of the neutron's spin.
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.
