‘Completely hypnotic’ donut of cell scaffolding swirls endlessly in mesmerizing new video

A “donut” of mesmerizing, cell-forming microtubules moving in sync is among the top entries in Nikon’s annual microscopic video competition.

Microtubules are proteins that make up the skeleton of a cell. Their movement is normally chaotic, but when restricted to a circular channel, they begin moving together and organize themselves into a coherent flow, according to Ignasi Vélez-Ceron, a doctoral candidate who filmed the video with his colleagues in the Department of Material Science and Physical Chemistry at the University of Barcelona in Spain.
