“Each ovary of the female fruit fly houses multiple ovarioles or ‘assembly lines’ in which individual egg chambers develop into fully formed fly eggs…In this picture, cross-sections of ten ovarioles from different female fruit flies are arranged with stem cells and early stage egg chambers at the center, and the more mature chambers at the periphery. The nucleus of each cell is stained yellow/orange. The cell membranes are stained blue.”

As written up by Aatish Bhatia at Wired, the winners of Princeton’s annual Art of Science competition are announced. “Among the entries are some wonderful ‘oops’ moments, where an experiment goes beautifully wrong, revealing art where you might not have expected to see it…But most of these submissions aren’t accidents. Many of these pieces reveal form, structure, and beauty hidden at a scale that our eyes can’t perceive.”
