Not sure why this article made it to front page, but fwiw, I used to work as a research engineer in a role where using a confocal microscope in clinical trial settings was a regular part of my job. AMA :D
The post did not get a lot of attention, but a couple of days ago I got what I think is my first offer to re-post from the admins, and since I still found the topic interesting I thought it was worth giving it a second chance.
Meta meta: it seems people are more inclined to question submissions' topicality these days, which I find a bit stressful. Submitting Wikipedia articles about cool/interesting/novel/unknown things (not only technical in nature, for sure) feels to me like a cornerstone of this place (and I've been here a while now).
I think it's OK when people question a topic and the answer expands their minds.
