Complex Structures Take Shape With Help From the Environment (7 of 12) (image) American Association for the Advancement of Science Share Print E-Mail Caption To make these architectures, we start by growing a coral structure (red). We then nucleate the green stems inside the cavities of the coral structure. While the stems are growing, we open them with a CO2 pulse (purple).
