From SciTechDaily, “Study Describes a Biological Transistor for Computing Within Living Cells”

An interesting article in SciTechDaily reports on a new study describing “a biological transistor that is made from genetic material (DNA and RNA) in place of gears or electrons.” From the article,
When Charles Babbage prototyped the first computing machine in the 19th century, he imagined using mechanical gears and latches to control information. ENIAC, the first modern computer developed in the 1940s, used vacuum tubes and electricity. Today, computers use transistors made from highly engineered semiconducting materials to carry out their logical operations.
And now a team of Stanford University bioengineers has taken computing beyond mechanics and electronics into the living realm of biology. In a paper published March 28 in Science, the team details a biological transistor made from genetic material — DNA and RNA — in place of gears or electrons. The team calls its biological transistor the “transcriptor.”
