2010 Small World Competition Winners

This post is created by me "rkpdesilva" for the sL-spirit.com and not a one like got from E-Mails Etc. This is the original post..........

2010 Small World Competition Winners

1st Place >> (mosquito) heart (100X)
100 වාරයක් විශාල කරනලද මදුරු හදවත


Malaria’s impact worldwide is still an issue, particularly in developing countries. Research is ongoing to study the carriers of malaria, mosquitoes, and how they carry and transmit the disease and other pathogens. That’s why the 2010 winning image by Jonas King is so important to the life science community.

Anopheles gambiae (mosquito heart) was captured at 100x magnification. Jonas works out of Vanderbilt University’s Hillyer Lab, which studies the interactions between mosquitoes and their pathogens, along with salivary components and how they interact with the vertebrate host’s immune response.

The image details the structural organization of the mosquito heart and provides insight into how mosquitoes move blood to all regions of their bodies. Jonas notes, “Mosquitoes remain one of the greatest scourges of mankind. Malaria infects hundreds of millions of people annually and is believed to have a major impact on the economies of endemic regions.”

2nd Place >> 5-day old zebrafish head (20X)
Dr. Hideo Otsuna is a postdoctoral research fellow at the University of Utah’s Neurobiology and Anatomy Department. His research focuses on neuro-anatomy of drosophila and zebrafish, particularly in creating accurate 3D/4D reconstruction of these organisms.

His image of a five-day old zebrafish head, magnified 20x, was taken using FlouRender, the university’s interactive rendering tool for confocal microscopy data visualization, which is designed especially for neurobiologists to help them better visualize the fluorescent-stained confocal samples.

Says Dr. Otsuna of the 3D volume method, “In my opinion, it’s not just good for visualizing the information captured by the microscope in research, but it’s also aesthetically superior than traditional methods.”

3rd Place >> Zebrafish olfactory bulbs (250X)
The processes that shape and change the developing and mature brain are some of the most complex in science. That’s exactly what Oliver Braubach sought to explore when snapping the photo of zebrafish olfactory bulbs. These structures bulge out of the anterior part of the brain and serve to organize and relay incoming olfactory information. The image taken for Small World was taken as part of preliminary experiments aimed at developing anatomical labels for different structures in the olfactory bulb. Since developing these labels, Oliver has used them to investigate how fibers from the nose contact cells in the brain and how these connections refine after they are initially formed.

The general focus of his photomicrography is the structure of the intact vertebrate nervous system. Oliver notes, “I think that it is possible to learn a lot about the function of the brain by looking at its intact structure, such as the anatomical connections between cell populations.”

In addition to his science work, Oliver is also an avid photographer and devotes much of his free time to taking pictures of materials unrelated to his work. As such, he has become increasingly interested in technical and artistic aspects of photomicrography.

4th Place >> Wasp nest (10X)
One of the great things about the Nikon Small World competition is you don’t have to be a science expert to submit an image and be selected as a winner. A lawyer from Italy, Riccardo Taiariol proves this with his beautiful image of a wasp nest, magnified 10x.

Microscopy is a hobby to Riccardo which he has been involved in for ten years. He generally looks to take pictures of protozoa, flowers and insects, which are relatively easy to find for those who are not scientists by trade.

Riccardo notes the image is significant because it “shows the hard job the insect had to do in order to build it.” It was taken using field stereomicroscopy.

When a former colleague sent him a section of an anglerfish ovary, James E. Hayden of The Wistar Institute came up with the idea of looking at the autofluorescence of the tissue in two colors. His vibrant swirling photomicrograph of developing oocytes, or unfertilized eggs, as they move along the spiral of an anglerfish's ovary came in fourth.

Mr. Hayden said he is drawn to both photographic art and science. “Most microscopists have a streak of artist in them. It’s hard not to. You’re looking at things through a microscope that most people don’t see. The nascent artist in you sort of peeks its head up.”

5th Place >>> (bird of paradise) seed (10X)
Viktor Sykora’s image of a bird of paradise seed was taken as part of a collection he is preparing for a publication about plant microphotography. His primary line of work is medical research and the development of new treatment strategies, but his hobby also happens to be photography.

The goal of this photo was to document variability in shape inside the plant world, which it demonstrates with exceptional aesthetic effect. It was taken using a stereomicroscope and digital camera.

6th Place >> (red seaweed), living specimen (40X)
Murdoch University
School of Biological Sciences and Biotechnology
Murdoch, Western Australia, Australia

7th Place >> Yongli Shan,
Endothelial cell attached to synthetic microfibers, stained with microtubules, F-actin and nuclei (2500X)

The University of Texas Southwestern Medical Center
Dallas, Texas, USA
Fluorescence, Confocal

8th Place >> Honorio Cocera-La Parra,
Cacoxenite (mineral) (18X)

Geology Museum, University of Valencia
Benetusser, Valencia, Spain
Reflected light
