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.
New analyses suggest strategies by which biological sensors may be able to measure changes in concentrations of chemical signaling molecules more accurately, but does this reflect what actually happens in nature?
