Researchers at Caltech have engineered a fundamentally new approach to killing cancer cells. The process uses small RNA molecules that can be programmed to attack only specific cancer cells; then, by changing shape, those molecules cause the cancer cells to self-destruct.

This type of therapy could do away with the side effects associated with conventional chemotherapy treatments. It also could be tailored on a molecular level to individual cancers, making it uniquely specific.
