Harvard, Princeton researchers developing implantable "biocomputers"

Researchers at Harvard and Princeton have announced that they've made a "crucial step" in the development of so-called "biocomputers," which could one day be implanted in patients to directly attack diseased cells or tissues Fantastic Voyage-style. According to Physorg, the computers are actually constructed entirely out of DNA, RNA, and proteins, and are able to translate complex cellular signatures like the activities of multiple genes into a form that can be more readily observed. Currently, the researchers have demonstrated that the biocomputers can work in human kidney cells in culture, although they seem confident that they'll eventually find a wind range of uses, including working in conjunction with biosensors or medicine delivery systems to target, for instance, only cancerous or diseased cells, without causing any harm to the patient's healthy cells.
