I just stumbled upon an incredible site called OR-live.com where you can witness live video of the latest surgical procedures. This is an excellent resource for researching and understanding how the medical field is saving lives and helping people to live longer and healthier. A few of my favorites below (warning: these videos may be hard for some people to watch):
Robotic Hysterectomy for Endometrial Cancer
Cochlear Implant Restores Partial Hearing to Completely Deaf Patient
