Protein caught in the act

Researchers have developed a new way to see where the molecules are active

Researchers have illuminated a once-hidden developmental process. A fluorescent signal pinpoints the activity of a protein in fruit flies, allowing researchers to see exactly when and where this protein does its job.

That's pretty damn swanky. I doubt it can be generalized to other proteins though, though I'll have to read the paper to know for sure.
