Under the microscope #3 – Water fountain (with Spirogyra algae)

Here are some nice images of the alga Spirogyra. These algae have a spiral-shaped chloroplast. The video also shows other algae in colonies.

This instructional video gives an introduction into the correct use of the microscope.



Video: The secret life of plankton

I just want to share a nice video that I found. It’s worth watching.



The Multitouch Microscope: The future of Microscopy?

This is a truly interesting innovation. The microscopy slide is scanned at high resolution and zooming and panning is done over the touch screen.
