	SuperNova/ Acceleration Probe, or SNAP

What is the mysterious dark energy that's causing the expansion of the universe to accelerate? Is it some form of Einstein's famous cosmological constant, or is it an exotic repulsive force, dubbed "quintessence," that could make up as much as three-quarters of the cosmos? Berkeley Lab physicist Eric Linder and Robert Caldwell of Dartmouth College show that physics models of dark energy can be separated into distinct scenarios, which could be used to rule out Einstein's cosmological constant and explain the nature of dark energy. Full story.

ESnet Connection Boosts
Idaho Lab's Bandwidth

The Idaho National Laboratory (INL) has taken significant steps toward giving its scientists and engineers dramatically improved access to computing capabilities outside of the laboratory. INL's high-performance computing infrastructure was connected in mid-August to the Energy Sciences Network (ESnet), which is operated by Berkeley Lab to support large-scale science collaborations at DOE labs nationwide. While a very small-scale connection had existed in the past, this new connection has hundreds of times the capacity, and better matches INL's envisioned computing needs. Full story.
