Engineers have designed cells that can count and "remember" cellular events, using simple circuits in which a series of genes are activated in a specific order. MIT and Boston University engineers ...

A simple circuit is a chain of different parts with wires and switches which allows electricity to flow around. All electrical appliances use circuits. For electricity to flow correctly, the circuit ...

Neural microcircuits consisting of a few neurons and their interconnections are small enough to be understood more completely than larger neural structures, whose complexity quickly becomes ...

We describe a general method for producing ultrahigh-density arrays of aligned metal and semiconductor nanowires and nanowire circuits. The technique is based on translating thin film growth thickness ...
