The BBC has a really cool article about using a technique called Diagnostic Radioentomology (DR) to scan a beehive and create a 3D image. It is a non-intrusive way to study bees in their hive without having to open it up and take a look. However, radioentomology is a bit too technical for my tastes. I think you would get more of the public behind this new technology if it was called Magic BugRays 3D Adventure.
Anyway, here is the article that shows a scan of one hive, but be warned, you have to sit through an advertisement before you get to the good stuff.
