This is a hashtag that's been going around that calls scientists to identify themselves and their research to the world of Twitter. It's become one of the most interesting hashtags in a while. Thanks to David Steen for starting this.
The goal of this was to remedy the fact that the majority of people can't actually name a real life scientist.
This comes at an important time in history when scientific acknowledgement is becoming jeopardised by the general public.
I highly recommend giving these a bit of a browse!
