Programmable Cells. Living Computers

This may be old news to you, maybe you'll have something to add. I remember reading about this a few years ago, how they can give a living cella positive or negative charge to run the computer. How long until they grow computers

Programmable Cells: Engineer Turns Bacteria Into Living Computers


Programmable Cells

ScienceDaily (Apr. 28, 2005) — In a step toward making living cells function as if they were tiny computers, engineers at Princeton have programmed bacteria to communicate with each other and produce color-coded patterns.

Heres another article on creating a living computer
"US researchers have created ‘living computers’ by genetically altering bacteria. The findings of the research, published in BioMed Central’s open access Journal of Biological Engineering, demonstrate that computing in living cells is feasible, opening the door to a number of applications including data storage and as a tool for manipulating genes for genetic engineering.
