Technique
Confocal
Magnification
63X (Objective Lens Magnification)

This is the second of three winning images from Jason Kirk in this year’s competition (see 7th place and his Image of Distinction). A professional microscopist and director of the Optical Imaging and Vital Microscopy Core facility at Baylor College of Medicine, Mr. Kirk took this image of neurons cultured from hippocampi of newly born mice. Note the level of detail and vast number of connections (dendritic spines) between these cells in this newly born specimen. This imaging is used in research of how certain proteins affect the development of dendritic spines.

Chameleon embryo (autofluorescence)

Technique
Fluorescence
Magnification
10X (Objective Lens Magnification)

This image of a chameleon embryo, taken during the Embryology course at the Marine Biological Laboratory in Woods Hole, Massachusetts, highlights the aesthetics and structure of these invertebrates. It was two images with the subject submerged in liquid. Great care was necessary to avoid refraction from the liquid.

Daphnia magna (Phyllopoda)

Image Stacking
Magnification
10X (Objective Lens Magnification)

Mr. Fauzan, a multiple winner in 2020 (see 5th place), is an engineer by trade and a microscopist by hobby. This image is of Daphnia magna, which is a small planktonic crustacean and popular scientific study subject. The image was taken to illustrate the details of the eyes and antenna area. Focus and clarity was achieved using image stacking techniques.
