Harvard's tiny DNA robots deliver cancer-killing treatment in lab

Drug delivery is becoming seriously sci-fi: Harvard University scientists successfully created a nano-like robot out of DNA that they believe can be a drug delivery stealth bomber, Bloomberg reports. According to the story, they envision being able to program the nano-sized construct made of DNA strands to carry a drug to a cell target. Once there, it would either kill a diseased cell or reprogram it into something safe. So far, they've accomplished this in a petri dish, making the tiny device open once it reached leukemia and lymphoma cells, according to the article. After releasing a payload of immune system antibodies, the cancer cells killed themselves. Details are published in the journal Science. Story
