Axonemes are molecular machines that enable the movement of cilia, the hair-like structures found on the surface of some cells. Atomic models of axonemes from the flagella of green algae and from the ...

Cilia are ubiquitous on cells, playing a variety of roles, Dr. Nicastro explained. While non-motile cilia serve as sensors for chemical and mechanical signals, motile cilia rhythmically beat to propel ...

Mechanical engineers have developed a system of artificial cilia capable of monitoring mucus conditions in human airways to better detect infection, airway obstruction, or the severity of diseases ...
