As a biologist, I'm always in awe of how many organisms we biologists destroy (kill) to study. As I was reading this article, I wondered how much of the meteorite you geologists have to destroy to study it. You addressed this:

Getting them out, frustratingly, requires the dissolution of the matrix rock via acid or other means.

So, my question is, how much of the meteorite do you have to destroy to properly analyze it? And what are the laws regarding that?
