BBC news: “…you know that we love robots…Spider robots…The BBC has just reported on such research from Columbia University by Dr. Milan Stojanovic, a professor of biochemistry. Dr. Stojanovic and his team have built what they call a "molecular spider" that has four legs, each of which are made up of 10nm strands of DNA…But Dr. Stojanovic isn't stopping there…he plans to build a microscopic arena for dueling spiders to go at it: "We could have a simple predator-prey system in which one of them would try to cleave the legs of the other." …a practical answer from him, explaining that "insulin could be steadily released from the surface of a tablet: if the spiders were sensitive to blood glucose, they could be automatically activated or halted according to the diabetic patient's immediate needs." That's useful, but BOR-ING! Dr. Stojanovic, let us know when we can start betting on molecular spider gladiator fights, ok?”
