Laser Light Offers New Tool for Treating Bone Cancer
Of the many ways to treat cancer, the oldest, and maybe most tried and true, is surgery. The goal is to remove all of the cancerous tissue while preserving as much of the surrounding healthy material as possible. "It's very hard to grow bone, so if you cut out bone, you basically lose it," says Lihong Wang, Bren Professor of Medical Engineering and Electrical Engineering; Andrew and Peggy Cherng Medical Engineering Leadership Chair; Executive Officer for Medical Engineering. A new diagnostic imaging technology developed by researchers at Caltech is offering surgeons the ability to make cuts 10 times more precisely, allowing them to preserve as much as 1,000 times more healthy tissue and to give patients easier recoveries.

New Research "UNCOVERS" Hidden Objects in High Resolution
Imagine driving home after a long day at work. Suddenly, a car careens out of an obscured side street and turns right in front of you. Luckily, your autonomous car saw this vehicle long before it came within your line of sight and slowed to avoid a crash. This might seem like magic, but a novel technique developed in the laboratory of Changhuei Yang, Thomas G. Myers Professor of Electrical Engineering, Bioengineering, and Medical Engineering; Investigator, Heritage Medical Research Institute, could bring it closer to a reality. "We can see all the traffic on the crossroads with this method. This might help the cars to foresee the potential danger that one is not able to see directly." explains electrical engineering graduate student Ruizhi Cao. [Caltech story]
Azita Emami Appointed to DARPA’s MEC Group
The Defense Advanced Research Projects Agency (DARPA) has named Azita Emami to the Microsystems Exploratory Council (MEC) for a three-year term beginning this summer. Emami is Andrew and Peggy Cherng Professor of Electrical Engineering and Medical Engineering; Executive Officer for Electrical Engineering; and Director, Center for Sensing to Intelligence. MEC brings over 30 of the brightest scientists and engineers together to identify new areas of development in microsystems science and technology and to recommend future possible research directions. The MEC Group was established by DARPA in 2017 to support its technology offices and provide continuing and independent assessment of the state of advanced microsystem technology as it relates to the U.S. Department of Defense.
Artificial Skin Gives Robots Sense of Touch and Beyond
A new artificial skin can now give robots the ability to sense temperature, pressure, and even toxic chemicals through a simple touch. The multimodal robotic-sensing platform, dubbed M-Bot, was developed in the lab of Wei Gao, Assistant Professor of Medical Engineering; Investigator, Heritage Medical Research Institute; Ronald and JoAnne Willens Scholar. It aims to give humans more precise control over robots while also protecting the humans from potential hazards. "I think we have shown a proof of concept," says Gao. "But we want to improve the stability of this robotic skin to make it last longer. By optimizing new inks and new materials, we hope this can be used for different kinds of targeted detections. We want to put it on more powerful robots and make them smarter, more intelligent." [Caltech story]
