Study Suggest Depleting Groundwater Increases California Quake Risk (May 13, 2015)
According to a study published online in the journal Nature, temblor frequency seems on the upswing in Central California because of groundwater depletion. As water tables drop, land subsides accordingly and the earth’s crust underlying the valley and its environs begins to rise. This pushes the surrounding coast range and Sierra Nevada skyward.This landscape-scale rebound relaxes the downward tension of the San Andreas Fault, likely increasing the risk of quakes.



UC San Diego Speeds Up Simulations (May 13, 2015)
Engineers at the University of California, San Diego, have developed a new family of methods to significantly increase the speed of time-resolved numerical simulations in computational grand challenge problems.

Rock 'em Sock 'em Politics (May 9, 2015)
Intense fighting, sequesters and threats of shutdown are what many people associate with the current government in the United States. If it seems that this tension has become more amplified, that's because it has. Since 2010, when Republicans gained control of both the House and Senate, gridlock in government has been even more pervasive and damaging to enacting legislative change. Eric Svensen, a researcher and lecturer in the Department of Government at The University of Texas at Austin, is wo...

Materials Scientists Putting New Spin on Computing Memory (May 5, 2015)
Ever since computers have been small enough to be fixtures on desks and laps, their central processing has functioned something like an atomic Etch A Sketch, with electromagnetic fields pushing data bits into place to encode data. Unfortunately, the same drawbacks and perils of the mechanical sketch board have been just as pervasive in computing: making a change often requires starting from the beginning, and dropping the device could wipe out the memory altogether. As computers continue to shri...

The Hubble Space Telescope, Our Window to the Universe, Turns 25 (May 4, 2015)
The Hubble Space Telescope launched 25 years ago. It’s easy to forget how revolutionary the project was, given that an entire generation of Americans has grown up accustomed to it beaming down stunning images of the cosmos on a regular basis. The first space telescope was proposed in 1923 by Hermann Oberth. Even then, it was clear that Earth-based telescopes operated at significant disadvantage. Not only are they impacted by light from cities, the atmosphere itself attenuates and blocks stars ...
