Computer design meets potions class: A little of vial 1 and a little of vial 2 yield six-bit computations encoded in DNA. Computer scientists at Caltech have designed DNA molecules that can carry out reprogrammable computations, for the first time creating so-called algorithmic self-assembly in which the same “hardware” can be configured to run different “software.”
In a paper published in Nature on Feb XX, a team headed by Caltech’s Erik Winfree (PhD ’98), professor of computer science, computation and neural systems, and bioengineering, showed how the DNA computations could execute six-bit algorithms that perform simple tasks...
