See The Microscopic World In Motion

The 17 best micro-videos of the year show us the world invisible to the naked eye
WATCH THE VIDEO! Everyone knows that oil and water just don't mix, but rarely have they looked so beautiful together. In this video, the drops of oil gradually coalesce, slowing down the process of evaporation. A better understanding of how oil moves in water can help researchers find better ways to clean up oil spills. John Hart, Dept. Atmospheric and Oceanic Sci, University of Colorado at Boulder

For the past 30 years, Nikon has held a contest for the year’s best microphotography images, and competition has been fierce. In 2011, they brought those still images to life, creating a separate category for videos, called the Nikon Small World In Motion competition.

This year, the competition was judged by Paul Maddox, a biology professor at University of North Carolina Chapel Hill. He had to choose from videos of a killer T-cell, a fruit fly’s locomotion, and stunning crystal formation to pick a winner that was original, informational, technically proficient, and visually striking. Today, Nikon announced the winning videos for the 2014 competition—check out all the finalists here.
