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.

'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.

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.

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.

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.

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.

Innovative coal-based product bumps petroleum out of equation
A team headed by West Virginia University has developed and successfully demonstrated a synthetic binder pitch that uses hydrocarbons from coal to supplement or replace petroleum feedstocks.

Secretary Bodman meets with Qatari officials to promote energy expansion efforts
On his fourth stop of a six-nation swing through the Middle East and Europe, US Secretary of Energy Samuel W. Bodman today met with Qatari Amir H.H. Sheikh Hamad Bin Khalifa Al Thani and Qatari Deputy Prime Minister and Energy Minister Abdullah Al-Attiyah to discuss energy sources.

Surplus electricity could 'fill up' plug-in vehicles
Plug in your car. Unplug foreign oil, greenhouse gases and other emissions that contribute to urban smog.

Discovering the details of dissolution
Ions in a liquid are like celebrities at a movie opening -- surrounded by fans who jostle each other to get as close as the velvet ropes around the red carpet will allow. So it is with ions in water or other liquids or solvents.

Cytochrome studies provide biofuel cell potential
Researchers from Pacific Northwest National Laboratory and collaborators have purified the protein called outer membrane cytochrome A (OmcA) from Shewanella oneidensis, a bacterium with promise for bioremediation of contaminants and the design of microbial fuel cells. They have measured its ability to bind and transfer electrons to mineral hematite, a solid ferric oxide. The team has shown that purified OmcA can directly reduce solid metals and that purified proteins are a next step in biofuel cell development.

Dust in the wind
In March 2006, a major dust storm occurred in Niamey, Niger. Although a common occurrence, this was the first time both satellite- and ground-based instruments were used simultaneously to assess the impact of airborne Saharan dust on incoming and outgoing solar radiation.

PNNL aims to move fast chemical weapon agentsensing technique from lab-top to prototype
In the same amount of time it takes to download software or print a picture, you now can detect a chemical weapon agent. Needless to say, technology is cool.

On thin icege/gi
Thin clouds high in the upper troposphere, like cirrus clouds, may have a significant influence on Earth's climate and enhance the "greenhouse effect" by absorbing more of the sun's radiation than they take in. Unknown is how ice crystals in these clouds absorb and reflect radiant energy and enhance the amount of radiant energy emitted toward the earth's surface.

Science and Technology Facility is first LEED Platinum Federal Building
A research facility at the U.S. Department of Energy�s (DOE) National Renewable Energy Laboratory has been designated as one of the most energy efficient and environmentally friendly places to work in the United States by the U.S. Green Buildings Council under its Leadership in Energy and Environmental Design (LEED) Green Building program.

Sailing for science
When most people think of an ocean cruise, they think of buffets and relaxing in deck chairs. For Pacific Northwest National Laboratory researcher Philip Long, an expedition cruise aboard the Joint Oceanography Institutes Deep Earth Sampling (JOIDES) Resolution research vessel meant 12-hour workdays examining ocean floor core samples for methane hydrate.

Carbon capture made easy
Gasification plants may be one of the keys to a hydrogen economy, if capture and sequestration of carbon dioxide (CO2) becomes technically and economically feasible. These plants would transform fossil fuel feedstock, including coal, biomass and municipal wastes, into clean-burning hydrogen gas where the only byproduct is water.

Nuclear energy and the 21st century
The world is entering a period of renewed interest and growth in nuclear energy, driven by rising oil prices, growing demand for electricity, new passively safe plant designs, and low emissions of greenhouse gases, which some governments need to meet Kyoto Protocol standards. The Kyoto Protocol assigns mandatory targets for reducing greenhouse gas emissions to signatory nations.
