(Phys.org) —The effects of gravity are relevant when building houses or flying airplanes, but biologists have generally accepted that the average cell is too small for gravity to play a role in how it is built or behaves. A finding by Princeton University researchers now shows gravity imposes a size constraint on cells. The results provide a novel reason why most animal cells are small and of similar size.
