Biological computer kills cancer cells
Israel - Israeli scientists who have built the world's smallest medical computer - so small that a million million of them would fit in a drop of water - have "diagnosed" prostate cancer and released a drug to kill cancer cells, they announce today.
So far, the technology has only worked in a test tube. But it could be another step towards the dream of nanotechnological medical machines, measured in millionths of a millimetre, that could operate inside a living human, identify the first signs of a developing disease, and deliver the right treatment - all before any symptoms appear.
