Just as our bodies have skeletons, so do our cells. They're equally indispensible in both cases. Without our bony skeletons we'd go limp and fall down. And without our cytoskeletons, our cells, which come in roughly 200 different ...

(Phys.org) —The amoeba Dictyostelium discoideum is the "favourite animal" for many biologists and some physicists: the unicellular organism, which usually lives in the soil, serves as a model for a very wide range of cells, ...
