YouTube as a video host / repository

Wayne

I received a note from Wayne this morning saying that he has worked out the mechanics of posting microscope movies to YouTube. YouTube is emerging as the most popular service for sharing small videos — functioning in many ways as Flickr does for still images. And, like Flickr, YouTube allows its material to be inserted into other sites as below. This is a fine development.

Wayne’s test YouTube video

Wayne’s caption: This film was made using a Swift FM-31 Field Microscope and Sony DSC-W7 Cybershot Camera, viewing a sample taken from a San Francisco Bay Salt Marsh pond at 800X magnification. The “snake-like” critters are Spirochete bacteria and the “boat-shaped” ones are Pennate Diatoms. Diatoms are algae in glass [silica] shells. That means they are tiny photosynthetic plants, using sunlight for energy. The role of the Spirochetes in this pond community is not known. Of the many millions of species of bacteria, only a very few are pathogens and even fewer are human pathogens. These little guys probably make their living digesting the remains of plant and animal material in the pond. The water in salt marsh ponds is often very salty, being as much as 5% salt.

And here is another test using Wayne’s handsome Mono Lake ameoba.

Ameoba on the move

Sample taken from Mono Lake, California. Viewed with a Swift FM-31 Field Microscope and Nikon Coolpix 885 at 400X. Mono Lake is a soda lake [sometimes called an “alkali lake”] with a high salt content and a high pH. Such water is toxic to humans and most animals, yet a large population of microorganisms lives in Mono Lake. The algal cells are similar to Chlorella and coated the bottom of the shallows. Numbers of these Amoebae were found, busily munching the algal cells.
