Weizmann Institute Scientists Create New Nanotube Structures  
Top: The cell pulls to maintain a fixed stretch in the gel. Middle: If the gel is externally stretched, the cell can reduce the force it exerts. Bottom: If the gel is alternately stretched and relaxed, the frustrated cell cannot "decide" how much force to exert. This results in the cell orienting perpendicular to the stretch direction
