A technique that allows manmade DNA shapes to be placed wherever desired—to within a margin of error of just 20 nanometers—now removes a major hurdle for the large-scale integration of molecular devices on chips.

Building on their creation of the first-ever mechanical device that can measure the mass of individual molecules, one at a time, a team of Caltech scientists and their colleagues have created nanodevices that can also reveal their shape.

Caltech professor Julia Greer is showing that the relationship between strength and weight is not graven in stone by creating brand-new materials that are incredibly strong but weigh next to nothing.

Integrating optics and electronics into systems such as fiber-optic data links has revolutionized how we transmit information. A second revolution awaits as researchers seek to develop chips in which individual atoms control the movement of light within the chip through optical "wires," and photons could replace electrons as the vehicle for performing computations. Andrei Faraon (BS '04), an assistant professor of applied physics and materials science in the Division of Engineering and Applied Science, presents a preview of this revolution at 8 p.m. on Wednesday, December 17, in Caltech's Beckman Auditorium. Admission is free.

Caltech materials scientist Julia Greer and her students have developed a method for constructing new structural materials by taking advantage of the unusual properties that solids can have at the nanometer scale, where features are measured in billionths of meters. They used this method to produce a ceramic (e.g., a piece of chalk or a brick) that contains about 99.9 percent air yet is incredibly strong, and that can recover its original shape after being smashed by more than 50 percent.

Researchers from Aarhus University in Denmark and Caltech have developed a new method for organizing molecules on the nanoscale. Inspired by techniques used for folding DNA origami—first invented by Paul Rothemund, a senior research associate in computation and neural systems in the Division of Engineering and Applied Science at Caltech—the team, which includes Rothemund, has fabricated complicated shapes from DNA's close chemical cousin, RNA.
