Ali Hajimiri Awarded $6 Million to Develop Self-Healing Circuits

04-08-09

Over the past few decades, the transistors in computer chips have become progressively smaller and faster, allowing upwards of a billion individual transistors to be packed into a single circuit, thus shrinking the size of electronic devices. But these circuits have an intractable design flaw: if just a single transistor fails, the entire circuit also fails. One novel way around the problem is a so-called self-healing circuit. Such circuits are "inspired by biological systems that constantly heal themselves in the presence of random and intentional failures," says Caltech professor Ali Hajimiri.

Erik Winfree Controls Complex Nucleation Processes using DNA Origami Seeds

04-08-09

"Flowers, dogs, and just about all biological objects are created from the bottom up," says Erik Winfree, associate professor of computer science, computation and neural systems, and bioengineering at Caltech. Along with his coworkers, Winfree is seeking to integrate bottom-up construction approaches with molecular fabrication processes to construct objects from parts that are just a few billionths of a meter in size that essentially assemble themselves. In a recent paper in the Proceedings of the National Academy of Sciences (PNAS), Winfree and his colleagues describe the development of an information-containing DNA "seed" that can direct the self-assembled bottom-up growth of tiles of DNA in a precisely controlled fashion. In some ways, the process is similar to how the fertilized seeds of plants or animals contain information that directs the growth and development of those organisms. [Caltech Press Release]

Professor Bruck Wins Richard P. Feynman Prize for Excellence in Teaching

02-25-09

Jehoshua "Shuki" Bruck, Caltech's Gordon and Betty Moore Professor of Computation and Neural Systems and Electrical Engineering, has won the Richard P. Feynman Prize for Excellence in Teaching. Caltech's most prestigious teaching honor, the prize was established in 1993 "to honor annually a professor who demonstrates, in the broadest sense, unusual ability, creativity, and innovation in undergraduate and graduate classroom or laboratory teaching." A member of the Caltech faculty since 1994, Bruck was the founding director of Information Science and Technology (IST) at Caltech. His research combines work on the design of distributed information systems and the theoretical study of biological circuits and systems. Kudos!

Man-made Reef Named in Memory Wheeler North

11-14-08

A man-made reef designed to grow into a self-sustaining 175-acre kelp forest - the biggest environmental project of its kind in the United States - has been named in memory Wheeler North (1922–2002), professor of environmental science at Caltech who pioneered the study of kelp and what makes for a healthy reef. The Wheeler North Kelp Reef is located off the coast near San Clemente. [OC Register Article]
