What do the crowd at a football stadium, the feet of a centipede, and the inside of your lungs have in common? All of these systems show the same specific kind of organization, as recently discovered ...

Using cryo-electron tomography, researchers have uncovered details of how the dynein motor protein drives cilia to beat. Understanding this motion may help to tackle health problems that affect cilia, ...

A team led by UT Southwestern Medical Center researchers has uncovered the atomic structure of a protein complex pivotal to the function of motile cilia, the hair-like structures extending from the ...

Motile cilia are tiny appendages that can be found on the surface of some cell types, such as lung epithelial cells. The regular beating of motile cilia can affect a variety of processes, including ...

Little is understood about how cilia, the tiny hairlike organelles that in humans are often the first lines of defense against pathogens in our lungs and respiratory tracks and even help push sperm ...

Attached to nearly every human cell is an antenna-like structure known as the primary cilium, which senses the cell's environment and controls how it responds to signals from its surroundings. New ...

Cilia have got to be some of the most amazing molecular motors found in cells. The means of locomotion of many a cell and a way of moving things around others, cilia are composed of microtubules, ...

After ovulation, an egg travels through the oviduct (Fallopian tube) toward the uterus (womb). This journey is essential for reproduction: Fertilization normally occurs in the oviduct, and the ...

Figure 1: an illustration of how the micrometer-scale hydrogel actuators work. a. When an external electric field is applied, water inside the soft hydrogel moves through its internal network, causing ...
