More importantly, the unique flagellar motion of the sperm can be recovered rapidly as soon as the flagellum starts to have components that are orthogonal to the illumination plane. The small ...

“Live spontaneous motion of flagella and cilia is observed everywhere in nature, but little is known about how they are orchestrated,” study co-author and mathematician Hermes Gadêlha said in ...

Led by Dr Vasily Kantsler of the University of Warwick's Department of Physics, the researchers discovered that all sperm tails (flagella) rotate in a counter-clockwise motion as they beat to ...

These findings may be used in future to better understand fertility issues associated with abnormal flagellar motion and other ciliopathies; diseases caused by ineffective cilia in human bodies.

Once the scientists learned EpsE was involved in repressing flagellar motion, they devised two possible explanations for how EpsE acts. The first was that EpsE acts like a brake by pushing a non ...

Still other microorganisms, such as the Volvox algae, are covered in flexible, undulating flagella whose coordinated waves add up to net motion. “Something that strikes me is the variety of ...

Single-celled algae and animal sperm cells are widely separated in evolution but both swim in the same way, by waving their protruding hairs, called cilia or flagella. Motion is driven by ...

Single-celled algae and animal sperm cells are widely separated in evolution but both swim in the same way, by waving their protruding hairs, called cilia or flagella. Motion is driven by molecular ...

Cilia and flagella are evolutionarily conserved, microtubule-based, hair-like organelles that protrude from the cell surface. They are the fundamental units of motion in cellular biology ...

Most bacteria have flagella; they are threadlike appendages extending from the surface of many microbes. They help move the organism around, a function called motility, in a rotating motion. Enabling ...

The researchers discovered that all sperm tails (flagella) rotate in a counter-clockwise motion as they beat to enable them to move through and against the motion of a fluid. Spermatozoa need to ...
