ScienceDaily (Mar. 30, 2011) — Researchers have built a computer model of the crowded interior of a bacterial cell that -- in a test of its response to sugar in its environment -- accurately simulates the behavior of living cells. The new “in silico cells” are the result of a collaboration between experimental scientists at the Max Planck Institute of Biology in Germany and theoretical scientists at the University of Illinois using the newest GPU (graphics processing unit) computing technology.
