Invention and evolution of the microscope
Since the invention of the first light microscope, microscopy has evolved so much. We are now able to see things at an atomic level. In this video, we will learn who invented the light microscope and the many other breakthroughs that...

Electron Microscopy (TEM and SEM)
We've talked a lot about light microscopy, but this technique has inherent limitations in resolution and magnification. The next paradigm in microscopy that emerged in the middle of the 20th century was electron microscopy. Because...

Vorticella sp. filter feeding. Vorticella is a genus of protozoa, with over 16 known species. They are stalked inverted bell-shaped ciliates, placed among the peritrichs.
Each cell has a separate stalk anchored onto the substrate, which contains a contractile fibril called a myoneme. When stimulated this shortens, causing the stalk to coil like a spring. Vorticella mainly live in freshwater ponds and...

Blepharisma japonicum is a Heterotrich Ciliate with the cell body 194 micrometre long, it is easily identified by a bright purple photopigment and is therefore a useful organism for developing and evaluating a molecular detection system.
Furthermore, the development of PCR based systems offers the potential for automation and eliminates the need for laborious microscopy by skilled individuals.

Vorticella sp. are often found in clusters, each stalk is individually attached to the surface. The stalk is made up of an external sheath that contains a fluid and a spirally arranged contractile fibril called a myoneme that contracts when stimulated.
When disturbed, the vorticella contracts and the stalk thread is shortened, causing the sheath to coil tightly like a spring.Phase Contrast illumination.
