Programmed to Fold: RNA Origami

08-20-14

Paul Rothemund, Senior Research Associate in Bioengineering, Computer Science, and Computation and Neural Systems, and colleagues have fabricated complicated shapes from DNA's close chemical cousin, RNA. "RNA origami is still in its infancy," says Rothemund. "Nevertheless, I believe that RNA origami, because of their potential to be manufactured by cells, and because of the extra functionality possible with RNA, will have at least as big an impact as DNA origami."

Celebrating with Professor Carver Mead

05-02-14

Carver Mead, Gordon and Betty Moore Professor of Engineering and Applied Science, Emeritus, celebrated his 80th birthday on May 1, 2014. Professor Mead is best known for his pioneering work on VLSI (very-large-scale integration) circuit technology in the 1970s and 1980s, which made it possible to greatly increase the number of transistors placed on a single semiconductor chip. It is no exaggeration to say that the computer era we live in would not have been possible without VLSI technology. He remains as passionate today about science and engineering as he ever was. "There isn't really a time when you're too old to have new ideas," Mead says. [Caltech interview] [Share Your Memories] [ENGenious article]

Bending the Light with a Tiny Chip

03-10-14

Ali Hajimiri, Thomas G. Myers Professor of Electrical Engineering, and colleagues have developed a new light-bending silicon chip that acts as a lens-free projector--and could one day end up in your cell phone. They were able to bypass traditional optics by manipulating the coherence of light—a property that allows the researchers to "bend" the light waves on the surface of the chip without lenses or the use of any mechanical movement.

A New Laser for a Faster Internet

02-26-14

Amnon Yariv, Martin and Eileen Summerfield Professor of Applied Physics and Professor of Electrical Engineering, and his group have developed a new laser that has the potential to increase by orders of magnitude the rate of data transmission in the optical-fiber network—the backbone of the Internet. "What became the prime motivator for our project was that the present-day laser designs have an internal architecture which is unfavorable for high spectral-purity operation. This is because they allow a large and theoretically unavoidable optical noise to comingle with the coherent laser and thus degrade its spectral purity," Professor Yariv describes. [Caltech Release]

Celebrating 50 Years of the Argon Ion Laser

02-14-14

William Bridges, Carl F Braun Professor of Engineering, Emeritus, discovered and patented the Argon ion laser on February 14, 1964, while at Hughes Research Laboratories. Today noble gas (argon, krypton, xenon) lasers are used in a variety of applications including DNA sequencers, cell sorters, eye surgery, and laser light shows. Professor Bridges' research work with lasers involved an airborne night reconnaissance system (AN/AVD-3), space communications systems, early high power laser weapons (the carbon dioxide gas dynamic laser), and hydrogen maser clocks for the global positioning system. He also holds the patent for the Ionized Noble Gas Laser. [Oral History of Prof. Bridges]

Professor Chandrasekaran Receives NSF CAREER Award

01-24-14

Venkat Chandrasekaran, Assistant Professor of Computing and Mathematical Sciences and Electrical Engineering, has been awarded the National Science Foundation's (NSF) Faculty Early Career Development (CAREER) Award for his 5-year project, “Computational and Statistical Tradeoffs in Massive Data Analysis”. The CAREER program is NSF's most prestigious awards for junior faculty members. The level and 5-year duration of the awards are designed to enable awardees to develop careers as outstanding teacher-scholars. Awardees are chosen because they exemplify the role of teacher-scholars through outstanding research, excellent education and the integration of education and research within the context of the mission of their organizations.
