Need to switch something on or off using a microcontroller? Using a transistor is one of the best ways to do this, but how exactly do you design properly for transistor switching? [Ben Krasnow] put ...

With its ability to store and transmit genetic information, DNA offers molecular cogs and gears that researchers can harness to produce biological circuits. Cells typically rely on gene expression to ...

To help achieve more precise control of gene therapy, engineers have designed a new control circuit that can keep gene expression levels within a target range. The method could be used to deliver ...
