Cells Can Be Living Calculators
MIT engineers have transformed bacterial cells into living calculators that can compute logarithms, divide and take square roots, using three or fewer genetic parts.
Inspired by how analog electronic circuits function, the researchers created synthetic computation circuits by combining existing genetic “parts,” or engineered genes, in novel ways.

To hold in esteem human courtesy and honor.
To associate with others with sincerity.
And to forever pursue the cultivation of oneself. — “The Purpose of Kendo” (All Japan Kendo Federation, 1975)
Pilot Tom Ryan took this self-portrait (look closely in the reflection on his visor) during a flight on NASA’s ER-2 in April 2011. The plane, which can operate at altitudes of 65,000 feet and higher, is a civilian version of the Air Force U2-S. It is kept at Dryden Flight Research Center in California and used in a variety of NASA’s Airborne Sciences field campaigns. This particular flight was to test a prototype of laser altimeter for the ICESat-2 mission, which will take key measurements of ice sheet elevation and changes. Credit: NASA/Tom Ryan

A welder at a boat-and-sub-building yard adjusts her goggles before resuming work, October, 1943. By 1945, women comprised well over a third of the civilian labor force (in 1940, it was closer to a quarter) and millions of those jobs were filled in factories: building bombers, manufacturing munitions, welding, drilling and riveting for the war effort.
