“The baby chicks were shifting and starting to pip—or trying to hatch. But not from an egg. 

Instead, these chickens were growing inside transparent 3D-printed plastic cups at the Dallas headquarters of Colossal Biosciences.

The biotech company today claimed it has developed a ‘fully artificial egg’ as part of its effort to resurrect extinct avian species, including birds like the dodo and the giant moa.

But ‘artificial eggshell’ would probably be a better description for the invention. It’s an oval-shaped printed lattice, coated inside with a special silicone-based membrane that lets in oxygen, just as a real eggshell does.”
