I know Python is used in the lab I'm in now to build software that analyzes the data we're spitting out of the lab and I know it's used a lot in physics research as well so I've pinned it as the language I should be learning.
I already know a little Python and Ruby (mainly I've just gotten through Zed's tutorials and made a few side projects), but are there any other languages people in the field have seen that are used specifically for research or that have pointed biomedical applications?
