Kevin DiVico on 13 Mar 13"In recent years, researchers in the messy world of biology have been able to build systems that function like the clean, binary switches on computer chips-and we've covered a number of reports in this area. Unfortunately, most of these share a significant limitation: they rely on proteins from bacteria that act as switches to turn genes on and off under specific conditions. We know about only a limited number of these genetic switches, which may set a severe limit on the number of logical operations we can string together inside a cell."
