Erik Winfree Controls Complex Nucleation Processes using DNA Origami Seeds


"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]

Undergraduates Win Southern California Regional Programming Contest


Caltech undergraduates Euiwoong Lee (class of '09), Seungwoo Shin (class of '10), and Ben Zax (class of '10) have won the ACM Southern California Regional Programming Contest. Coached by Donnie Pinkston, the team was the only team to solve all six problems of the challenge. Caltech has won the regionals for the last 6 years straight - and eight years out of the last nine. Kudos programmers!
