Video Showing a Toroidal Droplet (VIDEO)
Caption
This is a video of image stacks taken with a confocal microscope. The video is false-colored and demonstrates both the 3-D nature of the toroidal droplet as well as how the structure of the active nematic changes over time. The worm-like structures of the active nematic are microtubules driven by kinesin motor proteins. By analyzing the video, the researchers found that even with the molecular motors driving the system out of equilibrium, the defects were still able to sense the curvature.
