[DPR] Carnivorous plant image wins Olympus BioScapes competition
Olympus BioScapes competition
The open 'mouth' of a floating humped bladderwort plant (Utricularia gibba) took first prize in Olympus' microscope image competition. Igor Siwanowicz, a researcher from the Howard Hughes Medical Institute's Janelia Farm Research Campus in Ashburn, Virginia, took the winning image of the carnivorous plant, beating more than 2,000 entries from 71 countries.
In its 10th year, the Olympus BioScapes Competition celebrates images and movies of human, plant, and animal subjects as captured through light microscopes. See the top 10 in our gallery. Also, check out the honorable mentions on the BioScapes winners gallery.

Photographer: Kurt Wirz
Location: Basel, Switzerland
Specimen: 'Brother bugs.' Gonocerus acuteangulatus, two hours old. Size 3mm.
Olympus BioScapes competition
Photographer: Charles Krebs
Location: Issaquah, Washington, United States
Specimen: Phantom midge larva (Chaoborus) 'Glassworm.' Birefringent musculature that is usually clear and colorless is made visible here by specialized illumination.
Technique: Polarized light, 100X
Olympus BioScapes competition
Photographer: Yaron Fuchs
Location: New York, New York United States
Specimen: Mouse tail whole mounts showing hair follicle stem cells and proliferating cells.
Technique: Confocal imaging
Olympus BioScapes competition
Photographer: Fabrice Parais
Location: Caen, France
Specimen: Head and legs of a caddisfly larva: Sericostoma sp., a benthic macroinvertebrate that can be used for freshwater biomonitoring; because it is relatively sensitive to organic pollution and dies if water is dirty, it is a good indicator of water quality.
Technique: Stereo microscopy, 15x

Photographer: Ralph Grimm
Location: Jimboomba Queensland, Australia
Specimen: Paramecium, showing contractile vacuole and ciliary motion.
Technique: Differential interference contrast, 350x-1000x
