These visualizations show ice flow velocity at the surface from satellite observations (top) and as reconstructed from parameters derived by solving the inverse problem. The scale is kilometers per year. The inverse reconstruction most closely matches reality in the critical coastal areas. (Tobin Isaac, University of Texas.)

University of Texas researchers are out to improve computational models of ice sheets by refining estimates of basal friction: how much rocks and earth slow the sheet’s movement.


A smashing success

Since 2000, RHIC – for Relativistic Heavy Ion Collider – has pushed gold ions to near-light speeds around a 2.4-mile racetrack at Brookhaven National Laboratory. This is an image from the collider's Star detector.

The world’s particle colliders unite to share and analyze massive volumes of data.

A small subset of the particles from the Dark Sky Simulation Collaboration, showing a massive galaxy cluster at the center. Particles are colored by their incoming (blue) or outgoing (red) velocity with respect to the cluster. (See i

A team working on the Titan supercomputer simulates the biggest thing of all in a flash, then shares.
