The Rise of Ultrafast Waves

Traditionally, biochemical traveling waves are thought to propagate due to a coupling of bistable reactions with diffusion. Recent work proposes mechanisms by which cells achieve fast signaling without necessarily resorting to pure bistability or diffusion-mediated coupling.
