Changhuei Yang, Assistant Professor of Electrical Engineering and Bioengineering, and colleagues have turned science fiction into reality with their development of a super-compact high-resolution microscope, small enough to fit on a finger tip. This "microscopic microscope" operates without lenses but has the magnifyingpower of a top-quality optical microscope, can be used in the field to analyze blood samples for malaria or check water supplies for giardia and other pathogens, and can be mass-produced for around $10.

Studies of the brains of blind persons whose sight was partially restored later in life have produced a compelling example of the brain's ability to adapt to new circumstances and rewire and reconfigure itself. The research, conducted by postdoctoral researcher Melissa Saenz along with Christof Koch, the Lois and Victor Troendle Professor of Cognitive and Behavioral Biology and professor of computation and neural systems, and their colleagues, shows that the part of the brain that processes visual information in normal individuals can be co-opted to respond to both visual and auditory information.

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.

The NSF has announced three NSF CAREER Awards to Caltech faculty so far this year; they have been awarded to: Azita Emami, Assistant Professor of Electrial Engineering, Julia Greer, Assistant Professor of Materials Science, and  Beverley McKeon, Assistant Professor of Aeronautics. Emami's award is for her research on "Hybrid Data Communication in Advanced Integrated Systems"; Greer's awared is for "Experimental Investigation of Plasticity at Nano-scale via in-situ Mechanical Deformation"; and McKeon's award is for her research on "Morphing Surfaces for Flow Control". The CAREER program offers 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. The minimum CAREER award is $400,000.

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, 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.

Electrical engineering undergraduate student, Matthew Lew, has received the a Newport and Spectra-Physics Research Excellence Travel Award at the SPIE Photonics West Conference, held January 23, 2008 in San Jose. He won the award for his work on "Two-dimensional differential interference contrast microscopy based on four-hole variation of Young's interference" conducted in Changhuei Yang's Biophotonics Laboratory. This award is typically given to graduate students for outstanding research, Matthew Lew stands out in this year's batch of recipients as he is the only undergraduate to receive the prize.
