Caltech scientists have conducted experiments confirming which of three possible mechanisms is responsible for the spontaneous formation of 3-D pillar arrays in nanofilms. These protrusions appear suddenly when the surface of a molten nanofilm is exposed to an extreme temperature gradient and self-organize into hexagonal, lamellar, square, or spiral patterns.

Four Caltech faculty members are among the 65 scientists from across the nation selected to receive Early Career Research Awards from the Department of Energy. The grant winners are Guillaume Blanquart, Julia R. Greer, Chris Hirata, and Ryan Patterson. The Early Career Research Program is designed to bolster the nation's scientific workforce by providing support to exceptional researchers during the crucial early career years, when many scientists do their most formative work.

Stronger than steel or titanium—and just as tough—metallic glass is an ideal material for everything from cell-phone cases to aircraft parts. Now, researchers at the California Institute of Technology (Caltech) have developed a new technique that allows them to make metallic-glass parts utilizing the same inexpensive processes used to produce plastic parts. With this new method, they can heat a piece of metallic glass at a rate of a million degrees per second and then mold it into any shape in just a few milliseconds.

Congratulations to Chris Hallacy, Brad Saund, and Janet Chen for their victory March 8 in the 26th annual ME 72 engineering design competition. This year's theme: "Extreme Recycling." The mission: Design, build, and deploy two vehicles and traverse difficult terrain (water, sand, rocks, and wood chips, with one type of terrain in each of four different 6' x 10' boxes) to collect plastic water bottles, aluminum cans, and steel cans.

Where does violence live in the brain? And where, precisely, does it lay down its biological roots? With the help of a new genetic tool that uses light to turn nerve cells on and off, a team led by researchers at the California Institute of Technology (Caltech) has tracked down the specific location of the neurons that elicit attack behaviors in mice, and defined the relationship of those cells to the brain circuits that play a key role in mating behaviors.

A new class of artificial materials called metamaterials may one day be used to create ultrapowerful microscopes, advanced sensors, improved solar cells, computers that use light instead of electronic signals to process information, and even an invisibility cloak. In a Perspectives piece in this week's issue of the journal Science, Caltech's Harry Atwater and Purdue University colleague Alexandra Boltasseva describe advances in a particular subtype of these materials—plasmonic metamaterials.
