Emmanuel Candes Receives Information Theory Society Paper Award

08-18-08

Emmanuel Candes, Ronald and Maxine Linde Professor of Applied and Computational Mathematics, has garnered the 2008 Information Theory Society Paper Award jointly with Terence Tao and David Donoho. Their ground-breaking papers were cited for independently introducing the new area of compressed sensing, which holds great promise for processing massive amounts of data, and has already had a broad impact on a diverse set of fields, including signal processing, information theory, function approximation, MRI, and radar design.

Changhuei Yang Develops "Microscope on a Chip"

07-28-08

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.

Simona Bordoni and Tapio Schneider Offer New Explanation for Monsoon Development

07-25-08

Tapio Schneider, Associate Professor of Environmental Science and Engineering, has come up with a new explanation for the formation of monsoons. Schneider and colleague Simona Bordoni, who will start as an assistant professor at Caltech in 2009, propose an overhaul of a theory about the cause of the seasonal pattern of heavy winds and rainfall that essentially had held firm for more than 300 years.

Jeff Snyder and Colleagues Invent New Material that Will Make Cars More Efficient

07-25-08

Caltech Faculty Associate Jeff Snyder and colleagues have invented a new material that will make cars even more efficient by converting heat lost through engine exhaust into electricity. In a paper published July 25 in the journal Science, the scientists describe the unique thermoelectric material, which has twice the efficiency other such materials currently on the market, and works most effectively in the temperature range typical of automobile engines. The same technology could also work in power generators and heat pumps. Read more at www.sciencemag.org.

Axel van de Walle Developes Formalism to Represent Structure-property Relationships in Crystals

07-11-08

Axel van de Walle, Assistant Professor of Materials Science, has developed a general formalism to represent structure-property relationships in crystals. It enables the prediction, from a database of quantum mechanical calculations, of anisotropic material properties such as elasticity, piezoelectricity, dielectric constants, etc. As an application, he developed predictive models of anisotropic properties relevant to the design and optimization of III–V semiconductor epitaxial optoelectronic devices. This work was recently highlighted as the cover feature of Nature Materials. [Nature Article] [Commentary]

Melissa Saenz and Christof Koch Show that Sight Recovery After Blindness Offers New Insights on Brain Reorganization

05-29-08

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.
