MICROPHOTOGRAPHY

From spines on neurons to pollen on an insect’s eye, the winners of Nikon’s Small World photo contest offer a kaleidoscopic glimpse into a tiny world.

Microscopic photography has the power to bring what can usually only be seen through a lens in a lab into the spotlight. It’s a celebration of science and art that has been championed for 50 years by Nikon’s annual Small World contest.

This year’s winning photo—taken by research scientists Bruno Cisterna and Eric Vitriol—is a shot of brain tumor cells in mice. The image is part of a study that shows how neurons respond to deficiencies in their actin cytoskeletons, which controls the cells’ shape and structure. This response may play a role in neurodegenerative diseases like Alzheimer’s and Amyotrophic Lateral Sclerosis (ALS).

Of the 2,100 entries from across the globe, 87 extraordinary photos were recognized for their originality, technique, and impact. They included the pink and purple hues of an electrical arc soaring between a pin and a wire, and a close-up of the blister-like bubbles of a cannabis plant leaf.

Irregularly shaped blobs, containing bright green-dyed filaments and purple-dyed nuclei.

 

This year’s winning image shows neuroblastoma cells in mice. The green color represents the microtubules, white is the actin cytoskeleton, and magenta is the nucleus.

A wavy structure made of hexagonal cell compartments. The walls of the cellular compartments are a bright turquoise with splashes of orange. Along the wavy edge of the structure, translucent, blue, triangular hairs emerge.

Partially translucent and dyed bodies of T. gondii parasites, which look similar to two halves of a peanut side-by-side. The appear to be made of a matrix of filaments, dyed golden yellow.

About admin

I would like to think of myself as a full time traveler. I have been retired since 2006 and in that time have traveled every winter for four to seven months. The months that I am "home", are often also spent on the road, hiking or kayaking. I hope to present a website that describes my travel along with my hiking and sea kayaking experiences.
