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. 
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.
We make computers. Our brain is a computer. Nature is a computer. The whole universe is a computer. Not of the kind we think of. But a more sublime nature. A computer whose bits and bites are souls and spirits. A computer whose purpose is not to calculate but to find Love and Unity where it can.
