Spirals of Light May Lead to Better Electronics

A group of researchers at the California Institute of Technology (Caltech) has created the optical equivalent of a tuning fork—a device that can help steady the electrical currents needed to power high-end electronics and stabilize the signals of high-quality lasers. The work marks the first time that such a device has been miniaturized to fit on a chip and may pave the way to improvements in high-speed communications, navigation, and remote sensing.

New Gut Bacterium Discovered in Termite's Digestion of Wood

When termites munch on wood, the small bits are delivered to feed a community of unique microbes living in their guts, and in a complex process involving multiple steps, these microbes turn the hard, fibrous material into a nutritious meal for the termite host. One key step uses hydrogen to convert carbon dioxide into organic carbon—a process called acetogenesis—but little is known about which gut bacteria play specific roles in the process.

Team Led by Caltech Wins Second $10 Million Award for Research in Molecular Programming

During the past century, programmable technologies evolved from spinning gears and vacuum tubes to transistors and microchips. Now, a group of Caltech researchers and their colleagues at the University of Washington, Harvard University, and UC San Francisco are exploring how biologically important molecules—like DNA, RNA, and proteins—could be the next generation of programmable devices.

Caltech to Offer Online Courses through edX

To expand its involvement in online learning, the California Institute of Technology will offer courses through the online education platform edX beginning this October.

The edX course platform is an online learning initiative launched in 2012 by founding partners Harvard University and the Massachusetts Institute of Technology (MIT). Caltech's rigorous online course offerings will join those of 28 other prestigious colleges and universities in the edX platform's "xConsortium."

Made-to-Order Materials

Caltech engineers have mimicked lightweight yet strong biological materials by creating nanostructured, hollow ceramic scaffolds, and have found that their small building blocks, or unit cells, display remarkable strength and resistance to failure despite being more than 85 percent air.

Meet DALE: Solar Decathlon 2013 Construction is Under Way

Caltech students and recent graduates take classroom knowledge to the construction site.

Yeh and Schwab Named Kavli Nanoscience Institute Codirectors

Caltech professors Nai-Chang Yeh and Keith Schwab have been named codirectors of the Kavli Nanoscience Institute (KNI), a center supporting multidisciplinary nanoscience research on campus and beyond. Yeh and Schwab have both served as KNI board members and are the first to hold the title Fletcher Jones Foundation Codirector of the KNI; the position was recently endowed by a gift from The Fletcher Jones Foundation.

Arnold Appointed New Director of Rosen Bioengineering Center

Now in its sixth year of exploring the intersection between biology and engineering, the Donna and Benjamin M. Rosen Bioengineering Center has chosen Caltech professor Frances Arnold as its new director. Arnold, the Dick and Barbara Dickinson Professor of Chemical Engineering, Bioengineering and Biochemistry began her tenure as director on June 1.
