Balancing act
A Pacific Northwest National Laboratory researcher is developing approaches to spread the work evenly over scads of processors in a high-performance computer and to keep calculations clicking even as part of the machine has a hiccup.
Sizing up the scales
Exploring the breaking and rejoining of magnetic-field lines requires simulations and computation. A simulation’s accuracy, however, depends on various issues

Predicting solar assaults
When Earth’s magnetosphere snaps and crackles, power and communications technologies can break badly. Three-dimensional simulations of magnetic reconnection aim to forecast the space storms that disrupt and damage.

Quantum gold
Driven by what’s missing in experiments, Brookhaven’s Yan Li applies quantum mechanics to compute the physical properties of materials.
Star power
A Lawrence Livermore National Laboratory researcher simulates the physics that fuel the sun, with an eye toward creating a controllable fusion device that can deliver abundant, carbon-free energy.
Foiling airflow error
Portraying airflow over wings and other fluid movement is tricky. A Department of Energy award for early-career researchers is helping a former DOE CSGF fellow devise mathematical methods to decrease the error rate in fluid modeling.

Cosmic questions
MIT’s Dragos Velicanu is helping sort through data from the Large Hadron Collider for clues to the mysteries surrounding the strong force and the early universe.
Seeking new angles
Dragos Velicanu likes to look at just about everything from a fresh perspective. “Outside work, I like to travel, go
Sun on Earth
Simulations at Sandia National Laboratories reveal that using magnetism to heat and insulate fusion fuel could recreate solar conditions in the lab.
Putting Big Squeeze Fusion to the Test
A new Sandia National Laboratories-based approach to fusion that’s shown promise in computational simulations has passed its first bricks-and-mortar experimental
