Active matter is any collection of materials or systems composed of individual units that can move on their own, thanks to self-propulsion or autonomous motion. They can be of any size—think clouds of bacteria in a petri dish, or schools of fish.
Getting a clearer picture of microtubular movements was just one discovery in the study.
"Understanding the relationship between the flow—the global property of the system, or the fluid—and the topological defects, which describe the local orientation of microtubules, is one of the key intellectual questions facing researchers in the field," Grigoriev said."One needs to correctly identify the dominant physical effects which control the interaction between the microtubules and the surrounding fluid.
In the Georgia Tech model, though, the dynamics of active nematics—more specifically, the length and time scales of the emerging patterns—are controlled by a pair of physical constants describing those assumed dominant physical effects: the stiffness of the microtubules , and the activity describing the stress, or force, generated by the kinesin motors.
