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 and airplanes.

So although most people cover their mouths when sneezing in public, it also needs to happen in private even when there's nobody around. Of course, more study is needed to see if the sneeze "cloud" is even minimized with mouth-covering.

Surgical Video Recording: How I Do It

A number of people have asked how I go about video-recording surgeries... Beyond having hospital administration on board as well as obtaining appropriate consents from all involved parties, the technical aspects are actually quite straightforward.

I have tried all sorts of methods in order to obtain the closest and most vivid images possible. I tried cameras mounted on the surgical headlight which did work... but there was too much motion artifact leading to unusable footage. Even though I thought my head was absolutely still, it really was not.

What I found worked best is using the video tower used for sinus surgery in my hospital with the camera-head attached to the overhead light-handle. Thankfully, my hospital uses HD equipment with 3CCD camera-head, so the video footage is spectacular. And because the camera-head is mounted on a light-handle, the footage obtained is absolutely still.

The footage is recorded digitally directly onto a hard drive which I than transfer to a USB thumb drive.

Along with this setup, I have a roaming individual with a hand-held camcorder to obtain different angled shots to add variety to the final movie.

So that's how I now do it!

The specific video equipment I use is a Conmed Linvatec HD System... however any sinus surgery video equipment should work even if analog.

Revolutionary Camera Takes "Living" Pictures

Lytro has introduced a new type of camera that may have tremendous implications in medical photography.

It is a camera that takes a "living" picture. What does that mean?

In essence, it is a camera that takes a picture taking ALL the light information that is present such that the picture can be manipulated as if you haven't taken the picture yet.

It sounds confusing, but practically speaking, it means that one can literally refocus any part of a picture AFTER it has been taken. We are not talking about photoshopping using the blur or sharpen filter. It is literally refocussing a picture AFTER it has been taken!!!

You need to see it to believe it...

Click here to view some sample pictures. Touch (click) to refocus any part of the picture; pinch (double-click) to zoom.

I can't wait to see some medical photography done with this camera which starts at $399.

Purchase through the company's website.
