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.

Using a common metal most famously found in self-cleaning ovens, Sossina Haile hopes to change our energy future. The metal is cerium oxide—or ceria—and it is the centerpiece of a promising new technology developed by Haile and her colleagues that concentrates solar energy and uses it to efficiently convert carbon dioxide and water into fuels.

A Caltech-led team has created a palladium-based metallic glass that has a combination of strength and toughness at a level not previously been seen in any other material. The study demonstrates for the first time that the metallic glasses have the capacity to become the toughest and strongest materials ever known, the researchers say.

Ken Pickar's class, "Product Design for the Developing World," challenges Caltech students to solve some basic problems of the world's poor. The catch: in ten weeks, they must turn rough concepts into workable designs, including financial and market assessments. On December 7, this year's students presented their results. Their visual aids included a typically Caltech-like hodgepodge of pipes, motors, and fans—but as Pickar reminded the audience, "Prototypes aren't supposed to be elegant. They're supposed to be crude and quick."

An encounter with summer smog in Yosemite National Park led Caltech graduate student and accomplished nature photographer William Chueh to take action through science. His resulting research could help reduce the planet's dependence on fossil fuels, not to mention clean the air over Yosemite.

John O. Dabiri, a fluid-dynamics expert at Caltech whose studies of schooling fish have inspired new ideas for wind farming, was named a MacArthur Fellow, and awarded a five-year, $500,000 "no strings attached" grant. Each year, the John D. and Catherine T. MacArthur Foundation awards the unrestricted fellowships to individuals who show "exceptional creativity in their work and the prospect for still more in the future," according to the Foundation's website.
