The researchers' findings, reported in Nature Structural & Molecular Biology, which involve radial spoke 3 (RS3), help answer some fundamental questions about how motile cilia work and could ...

Some of the body's cells stay put for life, while others are free to roam. To move, these migratory cells rely on filopodia—sensitive, finger-like protrusions that reach out from the cell membrane ...

Over the last few decades, physical principles have been proposed to explain some biological processes and functions. However ...
