In 2007, when Oak Ridge National Laboratory (ORNL) researchers calculated that adding boron would bend carbon nanotubes, they did little with the information. Boron was one of several elements the computational scientists plugged into their model as they investigated ways to induce useful changes in nanotube structures. There were experiments to compare with the results [...]

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.
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.
For one summer, Sarah Richardson postponed her work computerizing yeast genome research and probed bacteria instead. As part of her Department of Energy Computational Science Graduate Fellowship, Richardson served a 2009 practicum under Adam Arkin, director of Lawrence Berkeley National Laboratory’s Physical Biosciences Division. She made important contributions to Arkin’s research into an RNA-based transcription [...]
A supercomputer’s unusual qualities make it a good fit with electric system problems.
Image searches typically rely on tags – text humans have attached to the pictures to identify objects or people they depict. The algorithms PNNL scientists Rob Farber and Harold Trease have created could largely eliminate tags because they recognize content automatically in massive amount of data. The application could make it as easy to index [...]
