Read the first sentence. Proper English it ain't!

You am too judgmental.

Well, like arnie, I was focusing on the Oxytocin, the love hormone, being used as a weight loss medication for men. However, I see your point about the first sentence. My story, and I am sticking to it, is that they first said, "Harvard has found a way...." Then some editor said, "Harvard doesn't do the research; their researchers do." So they changed it, but forgot to change the verb. Those sorts of edit mistakes happen to me all the time.
