Bothered by how quickly recording video drains your smartphone battery? There’s no app for that—but there may soon be a chip. Researchers at Sony and Stanford have constructed an imaging chip that incorporates a new technology called compressed (or compressive) sensing, to radically reduce battery drain by compressing video frames before they’re digitized.

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.
