Babies are already tiny bundles of chaos, but now scientists have found a rare form of diabetes that’s exclusive to newborns, caused by a sneaky gene called TMEM167A.

Researchers are geeking out, using stem cells to crack the code on this pint-sized medical mystery. Who knew babies could come with such a complex health plot twist?
