Researchers at the Technion-Israel Institute of Technology in Haifa have created an advanced biological computer using only bio molecules such as DNA and enzymes. There’s no traditional CPU or hard drive powering the bio-computer, no hardware or software, nor is there any tangible interface to the system. In addition to enhanced computation power, this DNA based transducer offers multiple benefits, including the ability to read and transform genetic information, and the aptitude to produce computational results that interact directly with living organisms.
