Dark Energy's 10th Anniversary, Part I
Celebrating the 10th anniversary of the discovery of dark energy, this three-part history recounts 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.

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.

DOE technology monitors CO2 injection in Australian gas field
Australia has launched the first carbon sequestration project in the southern hemisphere with the help of technology developed by researchers at the US Department of Energy. The Otway Basin Pilot Project will inject and monitor carbon dioxide in a depleted gas field in southeastern Australia to demonstrate the feasibility of storing the greenhouse gas in the Waarre Formation of the Otway Basin, and similar formations worldwide, to fight global climate change.

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.

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.

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.
