Some of its programming tricks bear an uncanny resemblance to ones the human brain has dreamed up. But DNA also works in ways human programmers find entirely alien. David Kestenbaum takes the occasion of the 50th anniversary of the first scientific description of DNA to speak with researchers trying to understand this odd and extraordinary piece of "software," which is the product of billions of years of evolution.
