A PNNL team builds models of deep-earth water flows that affect the tiny organisms that can make big contributions to climate-changing gases.
Supernova shocks
More than 10 years after simulations first suggested its presence, observations appear to confirm that a key instability drives the shock behind one kind of supernova.
Rewinding the universe
Dark energy propels the universe to expand faster and faster. Researchers are using simulations to test different conceptions about how this happens.
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.
