23 April 2012—With a zap of electricity and a flash of light, organic molecules pull together to form tiny conduits that conduct electricity as efficiently as metals do, researchers in France have found. The scientists say that the conductive organic nanowires could be useful for making low-cost flexible electronic circuits.

Seventy-five years is a long time. It’s so long that most of us don’t remember a time before the transistor, and long enough for many engineers to have devoted entire careers to its use and development. In honor of this most important of technological achievements, this issue’s package of articles explores the transistor’s historical journey and potential future.
