A Single Sneeze Can Spread Throughout Entire Building

MIT researchers using high-speed cameras and applying fluid dynamics have discovered that although ejected droplets from a sneeze typically fall to the ground, the "cloud" of moisture from a single sneeze actually floats and can enter ventilation ducts and can potentially spread throughout an entire building or airplane. Watch video below. These findings have profound implications as to how infections may travel within buildings and other contained structures like cruise ships a…

Surgical Video Recording: How I Do It

A number of people have asked how I go about video-recording surgeries ...

Wearable Camcorders for Video-Recording Surgeries From the Surgeon's Viewpoint?

An avid snow-boarder, I had the bright idea of using the ContourHD wearable camcorder I purchased to record snow-boarding runs... to instead video-record surgical cases. This wearable type of video-recording has many advantages over traditional camcorders which requires an assistant to shoot the video.
