Seems a bit condescending, why wouldn't a girl be able to do this?
Er... the last sentence was "What's of particular interest is the study's author is a 17-year-old high school student from Ohio." - the "interesting" part is that they're a highschool student and 17 years old, with a published scientific paper to their name. The summary doesn't even mention that they're a girl, you'd have to go and read the article to find that out.
Reading the article... what kind of first post-er are you?
