    • 2013 September-October,Kayri Havens,Sandra Henderson, “Citizen Science Takes Root”, inAmerican Scientist:
      Plants’life cycles are an attractive subject of study for citizen science because they are relatively easy to discern. In fact, the name for the field in which we work,phenology, literally means “the science of appearance.” The word was coined just a few years after Thoreau made his phenological observations, from the Greekphaino (to show or appear) andlogos (to study).

      Since it began operating in 1950, Sellafield has had different duties. First it manufactured plutonium for nuclear weapons. Then it generated electricity for the National Grid, until 2003. It also carried out years of fuel reprocessing: extracting uranium and plutonium from nuclear fuel rods after they’d ended theirlife cycles.
