A “doughnut” of mesmerizing microtubules forming cells that move in sync is among the best entries in Nikon’s annual microscopic video competition.
Microtubules appear squirrels which make up the skeleton of the cell. Their motion is normally chaotic, but when they are confined to a circular channel, they begin to move together and organize into a coherent flow, according to Ignacy Vélez-Serón, a doctoral student who made the video with his colleagues in the Department of Materials Science and Physics Chemistry at the University of Barcelona in Spain.
In the video, fluorescent microtubules move in synchronized waves around a donut-shaped channel with a hole in the middle. The film shows how small structures work together in collective behavior.
“I have been involved in the study of microtubule movement in this system for 3 years, and I was delighted and shocked when we were able to constrain our material and obtain this wonderful video,” Vélez-Cerón told Live Science in an email. “What’s more, I found the movement of the material to be completely hypnotic, spinning endlessly.”
The microtubule “doughnut” video won fifth place in the Nikon Small World in Motion contest on September 13. The competition consists of films and time-lapse photographs taken using microscopes.
“During my daily work, I’m used to seeing[ing] very beautiful phenomena through the microscope, and this competition allowed me to share them with people,” said Vélez-Cerón.
The winner of the 2022 competition was a time-lapse video of cell migration in a developing zebrafish (Danio rerio) of the embryo within eight hours, according to a statement published Nikon (opens in a new tab).
The jury evaluated each entry on originality, informativeness, technical skill and visual impact. 12-hour time-lapse cultural a monkey cells took second place in the competition, while a video of sea anemone neurons and burning cells took third place.
The judges also noted 25 other works, including a cell undergoing division, a holographic tardigrades shuffling, and time interval a Hydra eating a water flea (Daphnia is red). Hydra is a group of jellyfish-like invertebrates that constantly replace their cells with new ones, resulting in creatures biologically immortalLive Science reported earlier.
