• Resumen

  • It's a computer--inside a cockroach. Nanoscale entities made of DNA that can perform the same logic operations as a silicon-bass computer have been introduced into a living animal. Bioengineer Daniel Levner and his colleagues made the nanobots by exploiting the properties of DNA. When it meets a certain kind of protein, DNA unravels into two strands. Make the strands with particular DNA sequences and they will unravel on contact with particular molecules--say, those on a diseased cell. And if the DNA has drugs in its folds, it releases them when it uncurls.
