Keen eye on David's "child-like" fascination with thing. You can see him smiling at the little creatures on top of one of the ampules, almost as if he's like "Oh how cute ^^ ", as though they're newborn and as such he seems value in them, or value in their own lives. As for what he's doing with that goopy thing he pulls out of the container, I think he may have orders to conduct an analysis on these things.
But you mentioned that Mr. Weyland might be attempting to "recreate a child he lost". That reminds me of the movie, A.I. Artificial Intelligence, and how some of that movie's storyline touches upon recreating a child you lost. I recommend that movie, but I must warn you that it's very heavy; I saw it back in 2001 in theaters, and everyone in the theater was crying at the end, my older brother too, and they didn't get up off their seats until about a minute after the credits began rolling. I didn't at the time, but now when I see the movie, I leak. *ahem* Anyway, interesting hypothesis.
