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.

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.

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.

Moving grid operations from minutes to seconds
In the last century, the electric power grid has grown from a system that served one square mile in New York into a highlycomplex interconnected system that serves all of North America. Initially, individual local systems would connect to each other to share resources and increase reliability.

Coal: An energy bridge to the future
For years, coal drove the transportation business in this country, and it may be poised for a comeback. A hundred years ago, steam engines burned tons of coal as they pulled trains across the country. Now researchers are looking at converting that coal to liquid fuel to fill our gas tanks and move cars and trucks.

Fuel cell prototypes exceed expectations
Fuel prices continue to rise. However, one solution -- fuel cells -- is gaining on that problem. The Solid State Energy Conversion Alliance (SECA) has achieved the first of a threepart goal: developing solid oxide fuel cell systems that reduce fuel cell production costs by a factor of ten.

Hypernuclei at Jefferson Lab
In 1827, Robert Brown observed that pollen grains floating in a drop of water jiggled constantly. The phenomenon became known as Brownian motion. Over 75 years later, Einstein proposed that the pollen grains were being jostled by the molecules of water. The impurity (pollen grains) Brown had added to the water allowed Einstein to deduce the presence of individual water molecules and describe at least one of their properties.

Pocket-sized physics detector does big science
How do quarks and gluons, the elementary constituents of all matter, combine to form the protons and neutrons in the nucleus of the atom? This is a fundamental unsolved question in nuclear physics that researchers at Jefferson Lab are working to answer. The internal structure of the proton has been studied for several decades, and scientists have learned a great deal. However, much less is known about the structure of the neutron.

Spin structures of protons and neutrons
Just as a top spins on a table, the tiny quarks inside protons and neutrons also spin. Now a complex calculation by theoretical nuclear physicists at Jefferson Lab has revealed that a quark's spin may be altered by the surroundings of the proton or neutron in which it resides. This surprising result, recently published in the journal, Physical Review Letters, may lead to new insights about how ordinary matter is constructed.

On the leading edge
The Accelerator Division's Institute for Superconducting Radiofrequency (SRF) Science & Technology is a world leader in SRF accelerator technology research and design. Now the newest idea out of the Institute may revolutionize the way accelerating cavities are produced -- making the manufacturing process faster and cheaper, while producing cavities that could potentially outperform any other niobium cavities ever tested.
