Cutting Down on Cancer Surgeries

05-17-17

Engineers at the Optical Imaging Laboratory led by Professor Lihong Wang have developed an imaging technology that could help surgeons removing breast cancer lumps confirm that they have cut out the entire tumor—reducing the need for additional surgeries. “What if we could get rid of the waiting? With 3D photoacoustic microscopy, we could analyze the tumor right in the operating room, and know immediately whether more tissue needs to be removed,” Professor Wang explains. [Caltech story]

Laser-Induced Sound Waves Provide Live Panoramic Views of Tissue Functions

05-10-17

Lihong Wang, Bren Professor of Medical Engineering and Electrical Engineering, and colleagues are now able to take a live look at the inner workings of a small animal with enough resolution to see active organs, flowing blood, circulating melanoma cells, and firing neural networks. "Photoacoustic tomography combines light and sound synergistically for high-resolution imaging of molecular contrast," says Professor Wang. [Caltech story] [Read the paper]

One Step at a Time: A Conversation with Professor Ames

05-05-17

Aaron Ames, Bren Professor of Mechanical and Civil Engineering, handbuilds bipedal robots and designs the algorithms that govern how they walk. These algorithms couple efficiency equations with boundary constraints to teach robots to generate their own walking gait. [Interview with Professor Ames]

Professor Wennberg Elected to the National Academy of Sciences

05-02-17

Paul O. Wennberg, R. Stanton Avery Professor of Atmospheric Chemistry and Environmental Science and Engineering, as been elected to the National Academy of Sciences in recognition of his distinguished and continuing achievements in original research. His work applies traditional physical chemistry techniques to study the mechanisms of chemical transformation in the earth's atmosphere and in the carbon cycle. This research has helped create the Total Carbon Column Observing Network, which measures the distribution of greenhouse gases across the globe. [Caltech release]

Eye
Black Silicon Prevents Eye Implant from Gumming Up

04-13-17

Hyuck Choo, Assistant Professor of Electrical Engineering; Investigator, Heritage Medical Research Institute, and colleagues have developed an eye implant for glaucoma patients that could one day lead to more timely and effective treatment. Professor Choo has developed a passive system that eschews electronics and so needs no batteries and has no antennae. At just 600–800 micrometers in diameter, the sensor is the width of a few strands of hair. [Caltech story]

Observations Reshape Basic Plasma Wave Physics

04-06-17

Paul M. Bellan, Professor of Applied Physics , and colleagues have discovered a new way to determine the wavelength of energy flowing through plasma in space—a method that was recently applied during a NASA mission that yielded the first solid evidence of how energy sloshes back and forth in a magnetic wave that moves through the plasma surrounding the earth.

Seeing Deeper: An Interview with Lihong Wang

03-10-17

Using a combination of light and sound, Professor Lihong Wang is noninvasively peering deeper inside biological tissues than previously possible. His team uses three-dimensional photoacoustic microscopy and functional photoacoustic computed tomography to generate detailed color images of tumors and other structures inside the body.

New Materials Could Turn Water into the Fuel of the Future

03-06-17

Researchers at Caltech and Lawrence Berkeley National Laboratory have—in just two years—nearly doubled the number of materials known to have potential for use in solar fuels. "The key advance made by the team was to combine the best capabilities enabled by theory and supercomputers with novel high throughput experiments to generate scientific knowledge at an unprecedented rate," says John Gregoire, JCAP thrust coordinator for Photoelectrocatalysis and leader of the High Throughput Experimentation group.
