UPTON, NY - Scientists hoping to unravel the mystery of proton spin at the Relativistic Heavy Ion Collider (RHIC, http://www.bnl.gov/rhic/), a 2.4-mile-circumference particle accelerator at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, have a new tool at their disposal - the first to directly explore how quarks of different types, or "flavors," contribute to the overall spin of the proton.

BEER-SHEVA, ISRAEL, February 15, 2011 – Ben-Gurion University of the Negev researchers have developed techniques to manipulate root development functionality that can help plants better adapt to hostile growing environments.
In a recent paper published in the prestigious journal The Plant Cell, BGU researchers were able show that by manipulating a specific gene they could impact lateral root growth. Lateral root (LR) development is a highly regulated process that determines a plant's growth and ability to adapt to life in different environmental conditions.
(Santa Barbara, Calif.) –– An important milestone toward the realization of a large-scale quantum computer, and further demonstration of a new level of the quantum control of light, were accomplished by a team of scientists at UC Santa Barbara and in China and Japan.
The study, published in the Feb. 7 issue of the journal Physical Review Letters, involved scientists from Zhejiang University, China, and NEC Corporation, Japan. The experimental effort was pursued in the research groups of UCSB physics professors Andrew Cleland and John Martinis.

Mapping the Earth's magnetic field – to find oil, track storms or probe the planet's interior – typically requires expensive satellites.
University of California, Berkeley, physicists have now come up with a much cheaper way to measure the Earth's magnetic field using only a ground-based laser.
The method involves exciting sodium atoms in a layer 90 kilometers above the surface and measuring the light they give off.
CHAMPAIGN, Ill. — Illinois researchers have documented the first observations of some unusual physics when two prominent electric materials are connected: superconductors and graphene.
Led by University of Illinois physics professor Nadya Mason, the group published its findings in the journal Nature Physics.
Scientists aboard the Royal Research Ship James Cook have discovered a new set of deep-sea volcanic vents in the chilly waters of the Southern Ocean. The discovery is the fourth made by the research team in three years, which suggests that deep-sea vents may be more common in our oceans than previously thought.
Web experts ask scientists to use the Web to improve understanding, sharing of their data in science
Troy, N.Y. – Peter Fox and James Hendler of Rensselaer Polytechnic Institute are calling for scientists to take a few tips from the users of the World Wide Web when presenting their data to the public and other scientists in the Feb. 11 issue of Science magazine. Fox and Hendler, both professors within the Tetherless World Research Constellation at Rensselaer, outline a new vision for the visualization of scientific data in a perspective piece titled "Changing the Equation on Scientific Data Visualization."
RICHMOND, Va. (Feb. 11, 2011) – An international team of researchers has discovered a new class of magnetic superhalogens – a class of atomic clusters able to exhibit unusual stability at a specific size and composition, which may be used to advance materials science by allowing scientists to create a new class of salts with magnetic and super-oxidizing properties not previously found.

(Santa Barbara, Calif.) –– UC Santa Barbara scientists have made a discovery that has the potential for use in the early diagnosis and eventual treatment of plaque-related diseases such as Alzheimer's disease and Type 2 diabetes. Their work is published in a recent issue of Nature Chemistry.
EUGENE, Ore. -- (Feb. 10, 2011) -- A chronology of 1,000 years of earthquakes at the southern end of the San Andreas Fault nixes the idea that lake changes in the now-dry region caused past quakes. However, researchers say, the timeline pulled from sediment in three deep trenches confirms that this portion of the fault is long past the expected time for a major temblor that would strongly shake the Los Angeles Basin.
