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.”

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.”
