Gallery: This Year's Most Amazing Microscopic Photography

Winners of the Nikon's annual Small World competition represent the best in through-the-microscope photography

Nikon's annual Small World Competition began in 1974 to showcase the best microscope-aided photography. The competition attracts a fascinating variety of subjects, photographed using a range of microscopy techniques. Many of the images are scientifically important, but all are aesthetically stunning. This year's 137 winners have been announced, and we've got them all here for you.

1st Place: Arabidopsis thaliana (thale cress) anther (20x)

This strangely glowing, somewhat translucent shot captures the anther of a thale cress, an organism whose genome was fully sequenced in 2000. According to photographer and research scientist Dr. Heiti Paves, the photo has no scientific significance—it just happened to be the most artistic in his pile of thousands. Still, the thale cress is known to be a model organism in plant biology.Courtesy Nikon Small World Photo Micrography Competition: Photographed by Dr. Heiti Paves

2nd place: Sonchus asper (spiny sowthistle) flower stem section (150x)

Who knew a plant with small yellow flowers, spiny leaves and the potential to reach six feet in height could make for such a pretty picture? Cut the stem of this invasive weed and a milky sap will flow out, but you won't find that in the part pictured here. Although the dandelion-like blossoms are yellow, the stem boasts a range of colors hidden to the naked eye.Courtesy Nikon Small World Photo Micrography Competition: Photographed by Gerd A. Guenther

3rd place: Wrinkled photoresist (200x)

When objects like circuits are going to be chemically etched, they are often first covered with photoresist. Photographer Dr. Pedro-Barrios Perez inspects the photomechanical substance to make sure it will work when it goes to production. So why did he submit this picture? "It looks like the sun warming up the earth with its mighty energy waves," he says. Interesting, because photoresist sometimes wrinkles when exposed to heat.Courtesy Nikon Small World Photo Micrography Competition: Photographed by Dr. Pedro Barrios-Perez

4th Place: Anglerfish ovary (4x)

This cross-section of an anglerfish's ovary is reminiscent of another sea creature—the nautilus. Its otherwise-dull spirally composition caught James Hayden's eye, so he used fluorescent hematoxylin and Eosin stains to illuminate the different details of the image. "I was trying to create an image that sharply defined the boundaries of the different parts of the specimen, so that the image could actually be used to demonstrate the morphology of the ovary and eggs," he says.Courtesy Nikon Small World Photo Micrography Competition: Photographed by James Hayden

5th Place: Oral surface of a young seastar (40x)

This cute little guy is a juvenile seastar who just went through metamorphosis. It was likely accidentally caught by researchers netting plankton, and happened to transform in captivity. In the wild, the free-roaming larva's maturation would have necessitated a move to the bottom of the sea where it would have spent the rest of its life.Courtesy Nikon Small World Photo Micrography Competition: Photographed by Bruno Vellutini

6th Place: Discus fish scales (20x)

Originating in the Amazon, the discus fish is becoming an increasingly popular aquarium fish due to the ease of its care. Known for their striking colors, discus are considered to fall into one of three species – green, red or blue/brown. Hormones and food coloring are sometimes used by sellers to enhance the color of these fish. Not only will these dyes fade over time, they can also do serious harm to the fish.Courtesy Nikon Small World Photo Micrography Competition: Photographed by Dr. Havi Sarfaty

7th Place: Hair-like trichomes on Thunbergia alata (Black-eyed Susan vine) (450x)

The friendly black-eyed Susan vine can be found in late summer and fall gardens all across America. This picture provides a look at its trichomes, hair-like epidermal cells reflect solar radiation, reducing internal temperatures and a plant's water loss. Interestingly, THC production takes place in the cannabis plant's trichomes. Although Thunbergia alatas don't offer that, they still look pretty darn cool.Courtesy Nikon Small World Photo Micrography Competition: Photographed by Dr. Shirley Owens

8th Place: Cotton fibers stained with berberine sulphate and color depth shaded (200x)

These candy-colored cotton strands not only look pretty—they serve a purpose, too! Dr. Lloyd Donaldson snapped this shot of the stringy bits for a book on fiber structures. The use of confocal microscopy makes it possible to render 3-D images of tiny structures and then measure the diameter, for example, each thread.Courtesy Nikon Small World Photo Micrography Competition: Photographed by Dr. Lloyd Donaldson

9th Place: Olivine inclusions in gabbro (magmatic rock) (5x)

Gabbro is an intrusive igneous rock that forms in molten hot magma chambers far below the earth's surface. Humans can see its coarse grains, usually black, with the naked eye but, in this case, Dr. Bernardo Cesare used a microscope to see even more. He says "an unusual abundance of small inclusions in the larger crystals" of this sample give it the shocking colors you see here.Courtesy Nikon Small World Photo Micrography Competition: Photographed by Dr. Bernardo Cesare

10th Place: Algae and diatoms (10x)

Algae are often thought of as the pesky green gunk covering undisturbed ponds and lakes. What you might not realize, though, is the role algae and diatoms (which are actually oceanic plankton themselves) play in balancing the earth's climate. History has shown that the two contribute to the removal of billions of tons of carbon dioxide every year. Dr. Arlene Wechezak says she chose this photograph to "bring public awareness of the complexity and beauty of marine organisms."Courtesy Nikon Small World Photo Micrography Competition: Photographed by Dr. Arlene Wechezak

11th Place: “Alzheimer” Zebrafish, stained for Tau (red), neurons (green), and pathologic Tau (blue) (10x)

A translucent zebrafish larva showing the nervous system of the fish (green), the expression of the protein Tau (in red), and Alzheimer-like alterations of Tau (in blue). In humans Tau protein aggregates in the brains of Alzheimer patients and plays a major role in the degeneration of brain cells. By bringing Tau into translucent zebrafish larvae, the disease-causing effects of the protein can be studied directly under the microscope.Courtesy Nikon Small World Photo Micrography Competition: Photographed by Dominik Paquet

12th Place: Flow pattern in draining soap film (10x)

This piece of surreal art shows the flow patterns in a thin film of soap. A glass cylinder enclosed the flat soap film and kept it stable so that a close-up photograph could be taken. The striking black pattern is fringed with numerous pearl-like beads, a result of the fluid dynamics of the film.Courtesy Nikon Small World Photo Micrography Competition: Photographed by Dr. Tsutomu Seimiya

13th Place: Recrystallized melted mixture of acetanalide, resorcinal and carbon tetrabromide (33x)

Simple chemistry creates an otherworldly structure in this image. An organic solvent, an antiseptic and an outdated painkiller were combined to form this weird and complex crystal, illuminated with polarized light.Courtesy Nikon Small World Photo Micrography Competition: Photographed by Dr. John Hart

14th Place: Lobster egg (3.2x)

Nature's artistry is on display in this picture of a lobster egg a few days before hatching. The image was taken while scientists measured eye diameter, which is done to predict hatching time. The photography and microscopy may not have been too fancy, but the patterns and colors certainly are.Courtesy Nikon Small World Photo Micrography Competition: Photographed by Tora Bardal

15th Place: Atherix ibis (fly) aquatic larva (25x)

What seems to be the head of some strange horned creature is actually the back end of a watersnipe fly larva. These weirdly shaped larvae are found in freshwater, and they and other bugs are often good indicators of water quality.Courtesy Nikon Small World Photo Micrography Competition: Photographed by Fabrice Parais

16th Place: Snail eggs (200x)

These symmetric ovals are actually the eggs of a pond snail. Snails deposits their eggs in large jelly-like clumps into the water. This picture shows a close-up of two of these eggs, with embryos developing inside them.Courtesy Nikon Small World Photo Micrography Competition: Photographed by Massimo Brizzi

17th Place: Stopwatch (2.5x)

A colorful image showing the inner gears of a pocket stop watch. A confocal microscope, usually used to examine tiny biological materials, was used for this unusual look at the inner workings of the timepiece. This kind of microscopy can show the depth of the stop watch's various parts.Courtesy Nikon Small World Photo Micrography Competition: Photographed by Dr. Rebekah R. Helton

18th Place: Human skin on fibronectin with growth factor (60x)

This image captures a moment in the life of a human skin cell after it has been stimulated with a soluble growth factor. The cell shape was constrained, and after it was stimulated migratory structures extended from its membrane. The colors indicate proteins responsible for cell movement. By looking at how these proteins co-localize, scientists can understand how, when, and where they interact.Courtesy Nikon Small World Photo Micrography Competition: Photographed by Dr. Julia Sero

19th Place: Snowflake (40x)

A photograph captures this rare type of snowflake. It only lasted for 2 hours out of three days of snowfall in Beijing, but at least the image endures.Courtesy Nikon Small World Photo Micrography Competition: Photographed by Yanping Wang

20th Place: Rusted old coin (40x)

The rust and dirt on this old coin transforms into a greenish-brown moonscape under the microscope. Found buried under the sand, the coin may have newfound value as a piece of abstract art.Courtesy Nikon Small World Photo Micrography Competition: Photographed by Dr. Havi Sarfaty
