Georg Fritz at the University of Cologne and his colleagues are studying the way cells store and process information and then pass it on to subsequent generations of cells, reports the Technology Review's Physics ArXiv blog. The researchers say that a network of genes can act as a "conditional memory" that stores or ignores information when told to do so. "The circuit behaves similarly to a 'data latch' in an electronic circuit, i.e. it reads and stores an input signal only when conditioned to do so by a 'read command,'" the researchers say. The circuit, the blog adds, is almost like a modified version of the genetic toggle switch, but with higher levels of control.
