When David Linstead was about 9 or 10, he pestered his parents for a microscope.

It sparked a lifetime of scientific curiosity. David is now a retired research scientist with over 20 years of experience. In 2016, he captured an incredible slice of life in a microscopy photo that borders on fine art. The blue hues and fluorescent oranges and pinks burst through in a kaleidoscope of colors. To the uninformed eye, this image could be seen as evidence of alien life. But it's actually a photo of cat skin with hair and whiskers.

A polarized light micrograph of a section of cat skin, showing hairs, whiskers, and their blood supply. This sample is from a Victorian microscope slide. Blood vessels were injected with a red dye called carmine dye (here appearing black) in order to visualize the capillaries in the tissue, a newly developed technique at the time. This image is a composite made up of 44 individual images stitched together to produce a final image 12 millimeters wide. Image via David Linstead/Wellcome Image Awards.
