Mechanical engineering Assistant Professor Adela Ben-Yakar at The University of Texas at Austin has developed a laser "microscalpel" that destroys a single cell while leaving nearby cells intact, which could improve the precision of surgeries for cancer, epilepsy and other diseases. "You can remove a cell with high precision in 3-D without damaging the cells above and below it," Ben-Yakar says. "And you can see, with the same precision, what you are doing to guide your microsurgery." (source: sciencedaily.com)
