Using a molecular dimmer switch that smoothly dials up glowing lights in bacteria, researchers can make calculators in living cells that add, subtract, divide, and even do logarithms. [1]

These analog computations are much more powerful than those of previous, digital-based biological devices, says study author Timothy Lu, a synthetic biologist at MIT.
