Slightly misleading title: It's an Artificial Eggshell/Membrane. They took regular eggs, broke the shell/membrane and emptied the contents into a silicone based eggshell/membrane for incubation. Still good science, but greatly tempered implications. Allegedly a group of Japanese school students did this previously using cellophane wrap.
