Athanassios Siapas and Evgueniy Lubenov Reveal the Driving Factor in the Brain's Self-regulation

04-18-08

Using computer models of neuronal circuits and experiments on live rats, Athanassios Siapas, Assistant Professor of Computation and Neural Systems, and his postdoctoral researcher Evgueniy Lubenov are revealing the curious mechanism by which the brain spontaneously tips itself toward a state balanced between order and chaos. The driving factor in the brain's self-regulation, they say, is the timing of neural pulses. "Networks self-organize to an intermediate state, in between the two extremes," Siapas says.

Roukes and Rothemund Display Work at MoMA

04-10-08

"If you make structures that are impeccably designed, they also often tend to work really well," says Michael Roukes, Professor of Physics, Applied Physics, and Bioengineering. He along with senior research associate in computation and neural systems and computer science Paul Rothemund are scientists who can now add artist to their resumes. Rothemund's DNA origami and a colorized electron micrograph of Roukes's nanoscience work were displayed in Design and the Elastic Mind at the Museum of Modern Art (MoMA) in New York. Roukes's micrograph was even selected for the museum's permanent collection. [Caltech Press Release]

New Rosen Bioengineering Center Funded

04-03-08

Seeing a burgeoning new research field at the interface of biology and engineering, the Benjamin M. Rosen Family Foundation of New York has donated $18 million to the California Institute of Technology to establish the Donna and Benjamin M. Rosen Bioengineering Center. The Rosen Center will advance both basic scientific exploration and development of engineering analysis and synthetic approaches. Innovations in these areas are resulting in rugged and inexpensive diagnostic devices, in new insights into the functioning of the heart, and in the engineering of molecular devices capable of recognizing and responding to disease processes in individual cells.

Huaising (Cindy) Ko Receives Thomas J. Watson Fellowship

03-17-08

Mechanical Engineering student Huaising (Cindy) Ko was named one of only 50 college seniors in the nation to receive a $25,000 Thomas J. Watson Fellowship for a year of "purposeful exploration." Originally Ko chose to major in the biological sciences due to her interest in the field of medicine. However, at Caltech she discovered that the field of mechanical engineering fascinated her and allowed her to do interdisciplinary work related to her interests in medicine. As a Watson Fellow, Ko will be able to embark on another aspect of medicine that interests her: the tension between modern and traditional medicine. [Caltech Press Release]

Christof Koch and Colleagues Find Pupil Dilation Marks Decision Making

02-12-08

Christof Koch, the Troendle Professor of Cognitive and Behavioral Biology and Professor of Computation and Neural Systems, and his colleagues, have found that changes in pupil diameter correspond to the moment when a simple decision is made. The pupil, which is about 2 mm wide in bright light, dilated by as much as 1 mm at that moment--a change that, in theory, could be noticeable to a casual observer. [Caltech Press Release]

Changhuei Yang Invents New Technique That Makes Tissues Transparent

01-28-08

Changhuei Yang, Assistant Professor of Electrical Engineering and Bioengineering, and colleagues, have invented a new technique, turbidity suppression by optical phase conjugation (TSOPC), that counteracts the scattering of light and removes the distortion it creates in images, potentially allowing for light energy to be targeted to devices inside a human body.
