(Phys.org)—Neurons might not be able to send signals as fast as electrons in wires or photons in fiber, but what if they can communicate using miniature sonic booms? That would be quite a revolutionary discovery. A group ...
For the first time, the complex architecture of a protein that controls the transport of lipids between the two layers of a cell membrane has been described. With this structure, Biochemists from the University of Zurich ...
