20 BREATHTAKING AWARD-WINNING MICROSCOPE IMAGES


New Picture
20 Award-Winning Microscope Images
By
Twisted Sifter, 9 July 2012.

Olympus America Inc. is in the ninth year of sponsoring the BioScapes International Digital Imaging Competition. It honours the world’s most extraordinary microscope images of life science subjects.

The Olympus BioScapes Digital Imaging Competition recognizes outstanding images of life science specimens captured through light microscopes, using any magnification, any illumination technique and any brand of equipment. Each person entering can submit up to five movies, images, or image sequences (such as time lapse series). Entries must include information on the importance or “story” behind the images.

Below you will find a gallery of 20 winners and honourable mentions from last year’s competition. The entry deadline for this year is September 30, 2012. Be sure to visit www.olympusbioscapes.com for a complete gallery of winners, prizes and information for this year’s competition. Enjoy!

1. Rotifer Floscularia ringens feeding

New Picture

First Place: Rotifer Floscularia ringens feeding. Its rapidly beating cilia (hair-like structures) bring water that contains food to the rotifer. The “wheel animacules” were first described by Leeuwenhoek (ca.1702); when their cilia beat, they look like they have two wheels spinning on top. They live in reddish-brown tubes made of spherical “bricks.” Differential interference contrast microscopy. Charles Krebs, Issaquah, WA, USA. 2011 Olympus BioScapes Digital Imaging Competition.

2. Live green brain coral (Goniastrea sp.), under water

New Picture (1)

Fifth Place: Live green brain coral (Goniastrea sp.), under water. One full polyp in the centre is shown with four surrounding polyps. Walled corallites are purple. All colour is the natural auto fluorescence of the coral with the exception of the purple, which is near-violet LED illumination to highlight near transparent tissue. James Nicholson, NOAA/NOS/NCCOS Centre for Coastal Environmental Health & Biomolecular Research, Fort Johnson Marine Lab, Charleston, SC, USA. 2011 Olympus BioScapes Digital Imaging Competition

3. Stink bug eggs

New Picture (2)

Sixth Place: Stink bug eggs. Stink bugs are agricultural pests that exist throughout the world. When disturbed, they emit a characteristic foul-smelling odour. Brightfield illumination. Haris Antonopoulos, Athens, Greece. 2011 Olympus BioScapes Digital Imaging Competition

4. Fruitfly ovaries and uterus

New Picture (3)

Seventh Place: Fruitfly ovaries and uterus. The muscular and neural structure of the Drosophila melanogaster reproductive system is shown using fluorescence microscopy. The background staining of the eggs in red is a specific function of the mutant fly strain that is pictured here. Gunnar Newquist, University of Nevada, Reno, USA. 2011 Olympus BioScapes Digital Imaging Competition

5. Living diatom Mediopyxis helysia

New Picture (4)

Ninth Place: Living diatom Mediopyxis helysia, showing the cell nuclei and golden chloroplasts, captured using brightfield microscopy. On top there is a bacteria colony in mucilage. Specimen is from the North Sea. Wolfgang Bettighofer, Kiel, Germany. 2011 Olympus BioScapes Digital Imaging Competition

6. Spherical colonies of Nostoc commune

New Picture (5)

Tenth Place: Spherical colonies of Nostoc commune, a blue green alga. Darkfield illumination. Gerd Guenther, Duesseldorf, Germany. 2011 Olympus BioScapes Digital Imaging Competition

7. Trout alevin

New Picture (6)

Trout alevin (alevin is the second of four stages in the life cycle of a trout, when eggs hatch and the tiny fish begin to emerge). Stereomicroscopy. Robert Berdan, Calgary, Alberta, Canada. Honourable Mention, 2011 Olympus BioScapes Digital Imaging Competition

8. Weevil Eupholus, dried thorax scales

10. Tintinnid ciliate of the marine plankton, Petalotricha ampulla

New Picture (9)

Tintinnid ciliate of the marine plankton, Petalotricha ampulla. This preserved specimen (Lugol’s fixed) was caught with its cilia fully extended. It is about 100 microns long. Differential interference contrast microscopy. John Dolan, Station Zoologique B.P. 28, Villefranche-sur-Mer, France. Honourable Mention, 2011 Olympus BioScapes Digital Imaging Competition

11. Two damsel bugs (Nabis sp.)

New Picture (10)

12. Protozoan Elphidium crispum

New Picture (11)

Protozoan Elphidium crispum found growing on the Dorset coast of England. Brightfield. Michael Gibson, Northampton, UK. Honourable Mention, 2011 Olympus BioScapes Digital Imaging Competition

13. Juvenile live bay scallop Argopecten irradians

New Picture (12)

Juvenile live bay scallop Argopecten irradians. Through research, scientists are trying to help restore scallop populations in Rhode Island. Kathryn Markey, Aquatic Diagnostic Laboratory, Roger Williams University, Bristol, RI, USA. Honourable Mention, 2011 Olympus BioScapes Digital Imaging Competition

14. Cross-section of bulrush (Juncus sp.)

New Picture (13)

Cross-section of bulrush (Juncus sp.) leaf, autofluorescing red (chlorophyll on external side of leaf) and blue (vascular bundles). Diameter of the stalk is approximately 3mm. Jan Martinek, Ostrov, Czech Republic. Honourable Mention, 2011 Olympus BioScapes Digital Imaging Competition
