Top twitter accounts by reshares of research articles

This dataset is the result of looking at Twitter user profiles and asking:

* how often does each one tweet about research, and how often are those tweets retweeted,
hat tipped or 'via'ed (let's say 'resharing')
* how many unique accounts are doing the resharing
* how global those accounts are - how many unique countries are they from?
* what's the reach of those accounts? What's their total number of followers?
