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.

How cagey electrons keep hydrated
Water, despite its essential role in nature, remains a deeply mysterious substance. A long list of water's unusual properties tantalizes researchers even today, and scientists at the Stanford Synchrotron Radiation Laboratory and around the world are using X-rays to help address these questions. Working with SSRL scientist Anders Nilsson, researcher Dennis Nordlund and colleagues are turning up new clues, and their latest results are published in a recent issue of Physical Review Letters.

Energy savings deeply rooted at Jefferson Lab
When it comes to energy savings, Jefferson Lab has given a new meaning to dirt cheap. The lab uses a geothermal well system to control heating and cooling on two floors of one wing of its main administrative building. The wing, known as the F Wing, is a three-story, 61,000-square-foot addition that was constructed in 2005.

Using generalized particle distributions: Research collaboration seeks 3-D image of the proton
A computed tomography -- CT -- scan can help physicians pinpoint minute cancer tumors, diagnose tiny broken bones and spot the early signs of osteoporosis. Now physicists are using the principles behind the procedure to peer at the inner workings of the proton. In a recent experiment, members of Jefferson Lab's Deeply Virtual Compton Scattering collaboration found that it will be possible to construct three-dimensional images of the building blocks of the proton.

Studying the universe through pions
Pions are some of matter's simplest particles. They're built from the same building blocks as protons and neutrons -- quarks. The pion is the simplest particle built of quarks. The quarks are "glued" together by the strong force -- a fundamental force of nature that also binds quarks to form protons and neutrons. Studying the simple pion and its properties can reveal information about matter in the universe, where it came from and how it's held together.

Scientists study how the strong force builds the lightest particle made of quarks -- the pion
In Jefferson Lab's Hall C, an international collaboration of nuclear physicists, the Fpi collaboration, is studying how the strong force combines nature's fundamental building blocks into the lightest particle built of quarks -- the pion.

Reaching new heights in accelerator technology
The International Linear Collider is designed to collide high-energy electrons with high-energy positrons (electrons' antimatter counterparts). Once built, the ILC will serve as a powerful tool for scientists to address many of the most compelling questions of the 21st century -- regarding the fundamental nature of matter, energy, space and time, dark matter, dark energy and extra dimensions.

Researchers' hottest new laser beams 14.2kW
On Oct. 26, Free-Electron Laser (FEL) team members knew they were within reach of a goal they'd pursued for two years. They were aiming to produce 10 kW of laser light at an infrared wavelength of 1.61 microns. On that day, they blew past the milestone to produce 11.7 kW. Just four days later, on Oct. 30, they coaxed another two kW out of the machine setting the record even higher at 14.2 kW.

Lab enhances scientific data sharing with cutting-edge connection
In early 2005, researchers affiliated with Hall B wanted to transfer raw data from a recent experiment from the tape silo to computers offsite -- a task that without interruption would have taken the Lab's existing network connection almost seven days. Jefferson Lab's newly upgraded network connection is able to transfer data at a rate of up to 10 Gigabits per second, so that same transfer can now be completed in just 2.5 hours.

Big bite is reborn
At Jefferson Lab's recent Users Meeting, DOE's Dennis Kovar and NSF's Brad Keister emphasized the funding agencies' commitment to pursuing a cohesive nuclear physics research program in the United States. For instance, Jefferson Lab is funded by DOE; however, NSF provides for many of the Lab's Users and students and some of the instrumentation used in experiments, such as the recently upgraded BigBite spectrometer.

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.

Hopping hydrogen
Researchers at Pacific Northwest National Laboratory and the University of Texas at Austin discovered that a single hydrogen atom just can't keep still after it splits from a water molecule on the surface of the catalyst rutile titanium oxide. The hydrogen atom hopscotches across the oxygen atoms that stud the surface of the catalyst, while the hydrogen on what is left from water remains fixed, suggesting that the electronic structure of this popular catalyst is not entirely as it seems.
