High-speed Camera Captures Signals Traveling Through Nerve Cells

10-07-22

Scientists have developed a new ultrafast camera that can record footage of impulses as they travel through nerve cells. The camera technology, known as differentially enhanced compressed ultrafast photography (Diff-CUP), was developed in the lab of Lihong Wang, Bren Professor of Medical Engineering and Electrical Engineering; Andrew and Peggy Cherng Medical Engineering Leadership Chair; Executive Officer for Medical Engineering. "Seeing nerve signals is fundamental to our scientific understanding but has not yet been achieved owing to the lack of speed and sensitivity provided by existing imaging methods," Wang says.

Laser Light Offers New Tool for Treating Bone Cancer

09-20-22

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.
