Cells Are Like Robust Computational Systems

Gene regulatory networks in cell nuclei are similar to cloud computing networks, such as Google or Yahoo!, researchers report today in the online journal Molecular Systems Biology. The similarity is that each system keeps working despite the failure of individual components, whether they are master genes or computer processors.

“It’s extremely rare in nature that a cell would lose both a master gene and its backup, so for the most part cells are very robust machines,” said Anthony Gitter, a graduate student in Carnegie Mellon’s Computer Science Department and lead author of the Nature MSB article. “We now have reason to think of cells as robust computational devices, employing redundancy in the same way that enables large computing systems, such as Amazon, to keep operating despite the fact that servers routinely fail.”
