By David L. Chandler -<br><br>Researchers have made great progress in recent years in the design and creation of biological circuits — systems that, like electronic circuits, can take a number of different inputs and deliver a particular kind of output. But while individual components of such biological circuits can have precise and predictable responses, those outcomes become less predictable as more such elements are combined.<br><br><a href="https://newsoffice.mit.edu/2014/predictable-biological-circuits-1124">READ MORE ON MIT NEWS</a>
