Medical 'lightsabers': Laser scalpels get ultrafast, ultra-accurate, and ultra-compact makeover
Whether surgeons slice with a traditional scalpel or cut away with a surgical laser, most medical operations end up removing some healthy tissue, along with the bad. View More (2012-04-24)
Detecting malaria early to save lives: New optical technique promises rapid and accurate diagnosis
Correctly and quickly diagnosing malaria is essential for effective and life-saving treatment. But rapid detection, particularly in remote areas, is not always possible because current methods are time-consuming and require precise instrumentation and highly skilled microscopic analysis.
