Cells do more than carry out chemical reactions. New theoretical work suggests they may also generate usable electrical energy through constant motion in their membranes, offering a fresh way to think ...

Macromolecular diffusion in homogeneous fluid at length scales greater than the size of the molecule is regarded as a random process. The mean-squared displacement (MSD) of molecules in this regime ...

A group of physicists in Italy believes that mobile bacteria could convert chemical energy into mechanical energy by pushing on the teeth of tiny gear wheels. The researchers used computer simulations ...

Our Milky Way is not alone in the universe. Surrounding us are numerous satellite galaxies, taking part in a continuous grand dance. But how do these neighbouring galaxies behave, how do they interact ...
