Would it surprise you to learn that computers might be the cancer-fighters of tomorrow?

Researchers at the Weizmann Institute of Science have developed incredibly tiny computers   and they could someday be used to treat cancer and other diseases from inside your body.
These "computers" are so tiny, you'd need a microscope to see them - and they're essentially a mixture of synthetic DNA and enzymes, designed to hunt down diseased cells, and zap 'em with drugs. Scientists have discovered that strands of DNA can store huge amounts of information. In one ounce of dried DNA, you could have the computing power of over 1 trillion compact discs.
So, doctors would basically program the computers to search for the chemicals found in diseased cells. They'd inject trillions of them into a patient - And a tiny armada of cancer-killing computers would meander through your bloodstream until they detect clusters of sick cells and destroy them, all without any human supervision. So far, the tiny DNA computers work great at killing cancer cells in test tubes.
But there's lots of work ahead before scientists will know whether they'll work as well inside the human body. So, the research continues - and we'll keep you posted.
