Chaos reigned during the early phase of the Fukushima nuclear disaster, and people who fled the area have no idea how much radiation they were exposed to before the evacuation. But a scientist has come up with a novel approach to better evaluate their radiation doses by utilizing the logs of GPS-equipped cellphones.

Ryugo Hayano, a physics professor at the University of Tokyo, said he got the idea when he learned that Zenrin DataCom Co., a geographical information service firm, had acquired anonymous-format location logs of Global Positioning System-enabled cellphones with the consent of their users.

scientific collaboration around the world from 2005 to 2009:
From an extensive database of academic citations:
I extracted and aggregated scientific collaboration between cities all over the world. For example, if a UCLA researcher published a paper with a colleague at the University of Tokyo, this would create an instance of collaboration between Los Angeles and Tokyo.
