Science Daily reports that researchers have two CRISPR-CAS9 based core processors into human cells. Researchers at the Department of Bio-systems Science and Engineering at ETH Zurich in Basel led by Professor Martine Fussenegger, who is a professor in Biotechnology and Bio-engineering have found a way to use biological components to makes a CPU that can accepted all kinds of different programming. It uses the Cas9 protein at its core and with response to input from RNA sequences the CPU can regulate gene expression in a particular gene.
This type of research can be used for treatments of things like cancer. The CPU can detect certain bio markers and if one or the other is missing it can respond accordingly. This can mean that it can detect a marker that may show a cancer in metastasizing and therefore produce a chemical that can target those growths. They hope to further this research and even get into multi-core processors.
