From Max Hedt
To win $25,000 for proving that a “universal computer” – one that could solve any problem in mathematics given enough time and memory – could be built from biological molecules such as DNA, seems a rather easy earn (27 October, p 29). There already are biological, DNA-based computing systems that are smart enough to create electronic and mechanical devices to assist them in their mathematical calculations. I just wish, as one of them, that I had been smart enough to pull such a $25,000 boondoggle myself.
