Secondly, it's an important biomedical advancement made by citizen scientists. (The important part of that sentence is "by citizen scientists".)
I was a little confused when I saw that wording in the story, and now that I'm hearing this wording is the important part, I'm getting a little concerned. Are we not all citizens? Have we been divided into citizens and ruling class, now?
I'm all for popularizing science among all citizens, but I'd rather we word that as "science for the masses" or something.
