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

A timely death
Speed kills, as the slogan says, and in computers what it kills could be disease. Argonne National Laboratory researcher Andrew
A spontaneous collaboration
In 2007, when Oak Ridge National Laboratory (ORNL) researchers calculated that adding boron would bend carbon nanotubes, they did little

Kinky nanotubes
With the help of Oak Ridge computations, scientists are probing the properties of macroscale sponges made of nanoscale carbon-boron tubes. The material could soak up oil spills, help store energy or meet other needs.
A passion for pressure
Plasmas are the purview of Livermore scientist and Computational Science Graduate Fellowship alumnus Jeffrey Hittinger. He works both sides of the fusion street – inertial confinement and magnetic confinement – while simulating aspects of these tremendously hot, fast-moving particle clouds.

Twice-stuffed permafrost
A Pacific Northwest National Laboratory computation suggests that the water-gas compounds found in ocean permafrost can provide energy and store it, too – and then trap carbon dioxide.

Prime-time punch
The mantis shrimp packs one of the strongest punches on Earth. Computational Science Graduate Fellow Michael Rosario is investigating the physics, design and material properties behind the crustacean’s prey-crunching wallop. His research has landed him on the National Geographic Wild channel.
Inside the skull
Modeling the elements of blood flow in the brain could help neurosurgeons to predict when and where an aneurysm might rupture – and when to operate.
Power boost
Berkeley scientists have combined computational modeling and advanced materials synthesis to devise a low-cost anode that bolsters the feasibility of long-life lithium-ion batteries.
