RE: expressed sequence tag

That's interesting. I'd never heard of it before. It sounds like the kind of thing that would be done at NIH or the NCI, but it isn't anything I've ever come across in everyday practice.

Well let me explain why I asked. I was invited to be the graduation speaker for the class of students in training to become radiation therapists. (Rad. therapists are the people who actually operate the machines that deliver radiation to treat cancer.) The painting in question is one I want to use as a centerpiece of my presentation, as it allows me to linger on each panel for a moment to discuss various issues regarding cancer treatment and how the radiation therapists fit into the big picture. (For example, for the panel "The Diagnosis" I thought i"d read Raymond Carver's short poem, "What The Doctor Said.") The "EST" panel has me stumped. Perhaps I can simply admit defeat on that panel, glean a little comic relief from it and move on to the next panel.
