|Calculating that 0 + 0 = 0, 1 + 0 = 1, and 0 + 1 = 1 is normally no big deal. When the calculations are done in the lab using DNA molecules, however, these elementary manipulations look considerably more interesting. In the July 12  Science, a team of researchers at the Mount Sinai School of Medicine in New York City report that they have developed an algorithm that permits the use of single-stranded DNA reactions to add together two nonnegative binary numbers. More impressively, they have the experimental evidence to back their scheme...|
