These Award-Winning Photos Of The Microscopic World Will Blow Your Mind

On Tuesday, Nikon Instruments announced the winner of its Nikon Small World photo competition. The contest, founded in 1974, received more than 2,000 entries from scientists, artists and hobbyists in 90 countries.

A beautiful image of the dorsal side of a zebrafish won the first prize. The image was taken by Daniel Castranova and assisted by Bakary Samasa while they were working in the lab of Dr. Brant Weinstein at the National Institutes of Health. Not only was it an amazing microscopic photo, but the image was significant because it helped Castranova’s team in a groundbreaking study about the anatomy of zebrafish.

According to a press release, the image revealed that “zebrafish have lymphatic vessels inside their skull that were previously thought to occur only in mammals. Their occurrence in fish, a much easier subject to raise, experiment with, and photograph, could expedite and revolutionize research related to treatments for diseases that occur in the human brain, including cancer and Alzheimer’s.”
