A March 9 article features the above image of modified fruit fly embryos that display the Princeton University "P" and crest.
It is a marvel of nature: During gestation, multiple tissue types cooperate in building the elegantly functional structures of organs, from the brain’s folds to the heart’s multiple chambers.
