My buddy Bill Scully kindly sent me the link to a superb WSJ article on DNA Robots:
"For the first time, microscopic robots made from DNA molecules can walk, follow instructions and work together to assemble simple products on an atomic-scale assembly line, mimicking the machinery of living cells, two independent research teams announced Wednesday."
For the technically minded, you can read more about one of the team's research in their letter to Nature and some commentary on robots here. Two other letters were also published from Gu et al., and Lund et al. (subscription required for Nature).
Maybe just sometimes Science Fiction springs to life decades after the original imaginative creation in movies. Awesome.
