Introduction
Imagine a chicken hatching not from a shell of calcium, but from a transparent plastic cup—a feat that biotech startup Colossal Biosciences has turned into reality. By creating a fully artificial eggshell using 3D-printing and a clever silicone membrane, the company aims to revolutionize how we think about bird reproduction. With plans to resurrect long-extinct species like the dodo and the giant moa, and even boost conservation for endangered birds, this innovation sparks both wonder and controversy. Here are ten key things you need to know about this groundbreaking technology and its potential impact on science and nature.
