In the furnaces of the stars the elements evolved from hydrogen. When oxygen and neon captured successive α particles, the element calcium was born. Roughly 10 billion years later, cell membranes began to parse the world by charge, temporarily and locally defying relentless entropy. To adapt to changing environments, cells must signal, and signaling requires messengers whose concentration varies with time. Filling this role, calcium ions (Ca2+) and phosphate ions have come to rule cell signaling. Here, I describe our current understanding of Ca2+-mediated signaling (complementing several excellent reviews [Berridge, 2005, Burgoyne, 2007, Carafoli, 2004, Petersen, 2005 and Rizzuto and Pozzan, 2006]) and place particular emphasis on emerging themes related to Ca2+ binding proteins, Ca2+ entry across the plasma membrane, and the localized nature of Ca2+ signals. |

Feel free to quote any passages that show calcium ions guessing. |
You're an ass. |
True. But I'm also an ass that has forgotten more about chemistry than you'll ever know.
So, any evidence of calcium atoms guessing?
