For those of you who are here from Skepchick (and the rest of you too), HI!  Here is a little plug for other places you can follow Emma.  Being a school teacher and applying to grad school, she has a number of compartmentalized blogging personas.  This is where she explains interesting phenomena in science to lay non-scientists.  She also rants about her life and her activism at http://sigstarskeptic.wordpress.com/ (which is quite new at the moment) and blogs about high-level chemistry (paper summaries for grad school and research) at http://blog.curiouschemist.net/.  You can follow her at https://twitter.com/#!/sigmastarstate.
