Allan La Grenade-Finch remembers the moment an 8th grader, a “great kid” who often sat in the back of class and struggled with science, “lit up” during last year’s Hour of Code at Cardozo Education Campus in Washington, D.C. (more…)

This endless loop of light and darkness and the corresponding synchrony of internal and external clocks, are called circadian rhythms, from “circa diem,” Latin for “approximately a day.” Circadian rhythms influence almost all living organisms, from bacteria to algae, insects, birds and, as is increasingly understood by science, humans beings.
