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.

Big Bite does its stuff
Jefferson Lab's core mission is to study the heart of ordinary matter: the nucleus of the atom. Now Hall A has a new magnet and detector system designed to help physicists look at the nucleus in a whole new light. "BigBite" has debuted in its first experiment at Jefferson Lab.

G-Zero update
In research performed in Hall C, nuclear physicists have found that strange quarks do contribute to the structure of the proton. This result indicates that, just as previous experiments have hinted, strange quarks in the proton's quark-gluon sea contribute to a proton's properties. The result comes from work performed by the G-Zero collaboration, an international group of 108 physicists from 19 institutions, and was presented at a Jefferson Lab physics seminar on June 17.

"Smart" energy devices + real-time pricing = increased options for consumers
About 200 volunteers in the Pacific Northwest are testing equipment that is expected to make the power grid more reliable while offsetting huge investments in new transmission and distribution equipment. Pacific Northwest National Laboratory recently launched the Pacific Northwest GridWiseTM Testbed Demonstration, a regional initiative to test and speed adoption of new smart grid technologies that can make the power grid more resilient and efficient.

WSU and PNNL break ground on new facility
Washington State University and Pacific Northwest National Laboratory broke ground April 13, 2006, on the Bioproducts, Sciences, and Engineering Laboratory. The BSEL is a $24-million joint effort between WSU and PNNL. Located on the WSU Tri-Cities campus, researchers will use the laboratory to develop processes for converting low-value agricultural byproducts and residues into value-added chemicals for products like plastics, solvents, fibers, pharmaceuticals and fuel additives.

The sky's the limit
Earth's climate is noticeably changing over time. Glaciers are smaller, droughts last longer, and extreme weather events like fires, floods and hurricanes occur more frequently. PNNL researchers involved in the Atmospheric Radiation Measurement (ARM) Program are working to understand these phenomena through improved cloud representations in the computer models that simulate changes in the earth's climate.

A limitless potential
Researchers believe carbon nanotubes may prove to be the most promising nanoscale materials for multifunctional applications. These hollow tubes of carbon often have multiple, concentric layers of carbon sheets, like rings of a tree. A single-wall carbon nanotube (SWNT)--one sheet of carbon atoms rolled into a tube--has special properties resulting from a structure much more like that of a one-dimensional molecule than bulk graphite.

A new attraction
Jian Shen, a recipient of the Presidential Early Career Award in Science and Technology in 2004, is a research theme leader at the Department of Energy's Center for Nanophase Materials Sciences. Many predict that Shen's novel techniques for growing and studying magnetic nanostructures will attract a growing number of guest scientists to ORNL's new nanocenter.

Super-fast super-sensitive detectors
Only detectors with the greatest precision capabilities will measure up to the machine seeking to explore supersymmetry, dark matter, the Higgs mechanism, and new physics that hasn't yet been imagined. Their shapes and configurations might be familiar, but their inner workings–the materials and electronics charged with creating views of new physics–will carry a symbolic branding: "Product of the 21st century."
