Scientists have uncovered a new explanation for how swimming bacteria change direction, providing fresh insight into one of biology’s most intensively studied molecular machines. Bacteria move through ...
Cilia and flagella are small, microtubule-based organelles found on a wide range of eukaryotes, from single-celled protists to humans. These organelles protrude from the cell surface, acting as ...
The tail of a bacterial cell, known as a flagellum, allows the cell to propel itself through liquid. The flagellum is made of a hook, a basal body that acts as the motor, and a helical filament that ...
SOME cilia and flagella beat in a complex three-dimensional manner, and, in addition, the angular velocity at the tip is greater than at the base. Presumably the bundle of fibrils which make up a ...
(Nanowerk News) When speaking of motors, most people think of those powering vehicles and human machinery. However, biological motors have existed for millions of years in microorganisms. Among these, ...
This video presents a study in which, using cryo-electron microscopy, researchers determined the structure and mechanisms of a key component in the flagellar motor, which bacteria use to turn their ...
How well bacteria move and sense their environment directly affects their success in surviving and spreading. About half of known bacteria species use a flagella to move — a rotating appendage that ...
Bacteria move themselves forward by coiling long, threadlike appendages into corkscrew forms that function as makeshift propellers. University of Virginia Scientists Have Solved a Decades-Old Mystery ...
When it comes to bacteria, you may think we have it all figured out but some mysteries remain for decades like how these beings move. Now, an international team led by UVA’s Edward H. Egelman, PhD, a ...
Male infertility is an increasingly serious health problem affecting couples of reproductive age. Mutations in axoneme-associated genes cause male infertility. Dynein arm proteins are essential in ...
Bacteria are able to translocate by a variety of mechanisms, independently or in combination, utilizing flagella or filopodia to swim, by amoeboid movement, or by gliding, twitching, or swarming. They ...
