Allured by the chic perception and higher funding levels of disease-oriented research, many physicists have migrated to cell biology. Does physics really play a dominant role, or is cellular physiology slave to genetics and chemistry?
New simulations show that a high concentration of molecules can significantly increase the rate of reaction between two molecules, but does the setup reflect realities of biochemical reactions inside cells?

Water molecules driven into a cell membrane spontaneously generate holes through the membrane, according to simulations. The process has been used in the lab but not fully understood at the molecular scale.
