Programmable DNA Circuits Make Smart Cells a Reality – Sort of

… and imagine if you could program life itself.  Rather than 0’s and 1’s, you have four possibilities, a computing system performing quaternary arithmetics.

I still remember being dazzled as a freshman in college, during the first computer science lecture. The professor spoke of quantum computers, where improvements in speed of calculations can be measured in squaring time 2n rather than the traditional doubling time (i.e. Moore’s law) 2n.  And there was biologic computing, using simple building blocks of genetic material ACTG to perform calculations which take place in living cells.

Then, I spent the 15 years that follows writing them off as science fiction, pontifications of an old man.

I was, of course, wrong.
