A chemotherapy missile made of DNA target-locks on to cancer cells

DNA is the repository for genetic information. We’ve been tinkering with it since the 1970s, trying to alter the characteristics of organisms in a single generation, like boosting crop resistance to insect pests or even making pigs glow. Only recently have researchers popularized DNA as something else: a construction material.
