Over the last decade, scientists have been testing artificial corneas made from synthetic collagen gel. One of the difficulties is in getting the gel to take the right curved shape to fit the eye and focus light so the patient can see again.

 My colleagues and I recently found a way to make gel containing live corneal cells self-assemble into the correct pattern, like a piece of paper that folds itself into an origami design.
