Fabiancaptured this video using a research microscope from the 1970s, utilizing polarized light. He aimed to visually illustrate the symbiotic relationship between termites and these particular protists, to help audiences better understand the unseen role they play in our natural world. Fabian meticulously created an environment with a pH, chemical composition and temperature suited to keep the symbiontsalive. These symbionts are difficult to film due to their sensitivity to light and oxygen, and any slight changes to their environment can cause both the insect and the protists in its gut to perish.
"The most challenging part of capturing this video was finding the right solution for the creatures themselves," said Fabian. "I tried a lot of methods, even preparing my own saline solution. They're very sensitive to oxygen, so I had to remove as much gas from the solution as possible. It was very tricky, and I had to work fast. The video you're seeing is the result of months of trial and error, a lot of research and perseverance."
Protists are a wide and highly diverse array of single-celled organisms, but those featured in the winning video have formed a relationshipwith termites to process the cellulose they eat and help them derive nutrition from it and cycle carbon back into the soil. "Protists, while largely unknown to the generalpublic, are indeed the most abundant creatures on the planet," said Fabian. "There is a significant gap in our understanding aboutthese termite symbiontsand how this unique evolutionary relationship developed with its host, making it well worth exploring and presenting."
Fabian added, "The beautiful thing is that easy access to modern imaging and the internet has allowed those with an interest in microscopy to share their discoveries globally, across all boundaries of culture, language and age. The world is so small, and we can connect easily with anyone across the globe." Fabianhopes that his video will spark greater interest in Protists, as well as inspiring and encouraging more young peoples interested in STEM subjects.
"We're living in an amazing time when we have the ability to capture and share high-quality scientific imagery," said Eric Flem, Communications Manager, Nikon Instruments. "This year's winning entry highlights the power that microscopy has to connect like-minded individuals, educate others using engaging visuals, and spread scientific knowledge to the general public"
Second place was awarded to Dr. Stephanie Hachey and Dr. Christopher Hughes for their time-lapsed fluorescence microscopy video of an engineered human micro-tumor forming and metastasizing. In order to capture this video, stromal cells and cancer cells were introduced into a microfluidic platform under dynamic flow conditions and placed into a customized CO2 and humidity-controlled chamber. The platform was imaged every 15 minutes for 10 consecutive days.
