(DOE/Lawrence Berkeley National Laboratory) A group of scientists propose today in a refereed article in Environmental Research Letters to define the Rosenfeld as a unit for electricity savings, after the man seen by many people as the godfather of energy efficiency, Arthur Rosenfeld.

(DOE/Lawrence Berkeley National Laboratory) An international team led by a cosmologist at Lawrence Berkeley National Laboratory has extended the relationship between the x-ray luminosity and the mass of galaxy clusters as measured by gravitational lensing, improving the reliability of mass measurements of much older, more distant, and smaller galactic structures.

These refined measurements will benefit both the understanding of dark matter and the nature of dark energy as well.

(DOE/Lawrence Berkeley National Laboratory) Berkeley Lab researchers have developed a "molecular worm" algorithm that makes it easier and faster to simulate the passage of a molecule through the labyrinth of a chemical system, a progression that is critical to catalysis and other important chemical processes.

(DOE/Lawrence Berkeley National Laboratory) Wim Leemans of the Accelerator and Fusion Research Division at Lawrence Berkeley National Laboratory is one of six 2009 recipients of the U.S.

Department of Energy's highest honor, the E. O. Lawrence Award, for his pioneering research with laser wakefield accelerators.

(DOE/Lawrence Berkeley National Laboratory) The atomic-level action of a remarkable class of ring-shaped protein motors has been uncovered by researchers with the Lawrence Berkeley National Laboratory using a state-of-the-art protein crystallography beamline at the Advanced Light Source.

These protein motors play pivotal roles in gene expression and replication, and are vital to the survival of all biological cells, as well as infectious agents, such as the human papillomavirus, which has been linked to cervical cancer.

(DOE/Lawrence Berkeley National Laboratory) India may rank only a distant fourth in terms of carbon dioxide emissions, behind China, the United States and Russia, but its rapid economic growth rate coupled with aging and inefficient energy infrastructure suggest dire environmental consequences if "business as usual" continues.

That's why experts from the Lawrence Berkeley National Laboratory have been working to expand collaborations with India on energy efficiency.

(DOE/Lawrence Berkeley National Laboratory) By applying epitaxial strain to thin films of bismuth ferrite, Berkeley Lab researchers have produced a lead-free alternative to the current crop of piezoelectric materials.

(DOE/Lawrence Berkeley National Laboratory) Berkeley Lab researchers have developed the world's first acoustic hyperlens, a device that provides an eightfold boost in the magnification power of ultrasound, underwater sonar and other sound-based imaging technologies.

(DOE/Lawrence Berkeley National Laboratory) Hyper-SAGE can increase the strength of a remote MRI or NMR signal 10,000 times, making it possible to detect ultra-low concentrations of clincal and environmental targets.

This enhanced sensitivity presents a path to the molecular imaging of clinical targets such as lung and other cancers.

(DOE/Lawrence Berkeley National Laboratory) Scientists at the US Department of Energy's Lawrence Berkeley National Laboratory have confirmed the production of the superheavy element 114, ten years after a group at the Joint Institute for Nuclear Research in Dubna, Russia, first claimed to have made it.

The search for 114 has long been a key part of the quest for nuclear science's hoped-for Island of Stability.
