The Argonne-led Multiscale Coupled Urban Systems project will create a computational framework for urban developers and planners to evaluate integrated models of city systems and processes. With this framework, city planners can better examine complex systems, understand the relationships between them and predict how changes will affect them. It can ultimately help officials identify the best solutions to benefit urban communities.

A team of researchers in the US and Europe are part of the Real-Time Super Lab concept to study how electricity can be rerouted across vast distances to address disruptions. The team envisions that large-scale blackouts can be prevented by moving electricity intercontinentally, the same way utilities currently do regionally but at a much larger scale. Such global interaction can reduce the cost of outages and make electrical power grids of the future more resilient.
19-Sep-2017 A TOAST for next generation CMB experiments
Computational cosmologists at Berkeley Lab they recently achieved a critical milestone in preparation for upcoming CMB experiments: scaling their data simulation and reduction framework TOAST to run on all 658,784 Intel Knights Landing Xeon Phi processor cores on the NERSC's Cori. The team also implemented a new module to simulate the noise introduced when ground-based telescopes look at the CMB through the atmosphere.
An experiment called ALICE at the Large Hadron Collider is dedicated to the study of heavy-ion collisions. ALICE stands for 'A Large Ion Collider Experiment.' Its aim is spotting the high-energy, elementary particles, like electrons and gamma rays, streaming from the quark-gluon plasma, to explore the physics of the early universe. Oak Ridge National Laboratory physicist Thomas M. Cormier provides an update on the experiment.
Setting up a supercomputer is far more complicated than just bringing it home from the electronics store. Staff members of the Department of Energy's supercomputing user facilities spend years on the process, from laying out requirements through troubleshooting. In the end, they run some of the most powerful computers in the world to help solve some of science's biggest problems.

19-May-2017 A fresh math perspective opens new possibilities for computational chemistry
A new mathematical "shortcut" developed by Berkeley Lab researchers is speeding up molecular absorption calculations by a factor of five, so simulations that used to take 10 to 15 hours to compute can now be done in approximately 2.5 hours. These algorithms will be incorporated in an upcoming release of the widely used NWChem computational chemistry software suite later this year.

Pioneering X-ray experiments at Berkeley Lab's Advanced Light Source (ALS) helped bring to life decades-old theories about exotic topological states of matter, and the ALS continues to play an important role in this flourishing field of research.
30-Mar-2017 Physicists move closer to listening in on sub-atomic conversation
Much like two friendly neighbors getting together to chat over a cup of coffee, the minuscule particles in our sub-atomic world also come together to engage in a kind of conversation. Now, nuclear scientists are developing tools to allow them to listen in on the particles' gab fests and learn more about how they stick together to build our visible universe. The first complex calculations of a particle called the sigma have been carried out and published in Physical Review Letters.
