Computational sciences gets a Harvard institute
Projects such as looking at blood flow in the coronary arteries highlight the value of computation to understand problems in a variety of disciplines, including engineering, medicine, biology, the physical sciences and business. Seeing the need to expand course offerings and graduate student research opportunities, Cherry Murray, dean of the Harvard School of Engineering and [...]
In climate modeling, speed matters
A Brookhaven team wants to build the ‘fast physics’ behind clouds, air-suspended particles and precipitation into global climate models.
The wings that fly FASTER
If FASTER can be considered a jet that speeds global climate modelers to analyze fast physics processes, its wings are the testbed and associated research. The testbed integrates two major “fast” components: a single column model (SCM), a roughly 100 kilometer by 100 km column that complements traditional global climate models; and a numerical weather [...]

Seeing the invisible
Armed with computing power from Oak Ridge National Laboratory, researchers are detailing the nature of dark matter surrounding a galaxy much like our own Milky Way.
Dark matter predictions put to test
Collisions in dark matter “clumps” should produce gamma rays, but a satellite looking for them has come up empty so far.
Parsing particle experiments
A detector suggested dark matter collisions, but no other test has seen similar signs.

From Cuba to Cambridge by way of Miami
The former Computational Science Graduate Fellowship recipient escaped the communist regime with his family, then found a love of physics.
Forceful thinking
A quantum curiosity called the Casimir force gums up micro- and nanomachines. Work at MIT led by a newly minted alumnus of the DOE Computational Science Graduate Fellowship suggests uses for the force – and ways around it.
Getting a grip on the grid
A PNNL team enlists new algorithms and powerful computers to quickly analyze which combinations of failures most threaten the power grid.
Grids grasp at multiple threads to block blackouts
A supercomputer’s unusual qualities make it a good fit with electric system problems.

A well-placed plug for the humble algorithm
The ceremony in the East Room of the White House, where President Obama bestowed the National Medal of Science on Berni Alder last October, represented the public side of the honor. But for Alder the real action occurred after the ceremony, at a White House meeting for invited guests, politicians, family and other Washington dignitaries. [...]
The master of Monte Carlo
Berni Alder’s Monte Carlo methods have solved problems across the scientific spectrum. Yet the Livermore-based National Medal of Science-recipient still has questions.
Going big to study small
It takes a big computer to model very small things. And, like its namesake state, New York Blue is big. Made up of 36,864 processors, the massively parallel IBM Blue Gene/L is housed at DOE’s Brookhaven National Laboratory (BNL) on New York’s Long Island, where, among other things, it’s used to model quantum dots, or [...]
