Nikon announced the winners of the annual Small World in Motion competition on April 27. The photomicrography contest first introduced a video category in 2011, which includes digital time-lapse footage taken through a microscope. As a preview, they shared some of the finalists' videos from this year's competition with us, which we've edited together. More than than 130 entries were received this year, featuring remarkable footage that spans everything from embryonic mouse kidneys to a killer T cell engaging a cancer cell. Enjoy a trip into the microscopic world with this incredible footage. The full list of winners can be found here: Watch more videos: Subscribe to The Atlantic on YouTube:
