Artificially Expanded Genetic Information System (AEGIS) is a synthetic DNA analog experiment that uses some unnatural base pairs from the laboratories of the Foundation for Applied Molecular Evolution in Gainesville, Florida. AEGIS is a NASA-funded project.....

The system uses twelve different nucleobases in its genetic code. These include the four canonical nucleobases found in DNA (adenine, cytosine, guanine and thymine) plus eight synthetic nucleobases). AEGIS includes S:B, Z:P, V:J and K:X base pairs. https://en.wikipedia.org/wiki/Artificially_Expanded_Genetic_Information_System

"It's evolving. It's doing what we designed it to do," said Benner, a biochemist with the Gainesville, Fla.-based Foundation for Applied Molecular Evolution. https://www.nbcnews.com/id/wbna29430688

The aegis (Ancient Greek: αἰγίς aigís), as stated in the Iliad, is a device carried by Athena and Zeus, variously interpreted as an animal skin or a shield and sometimes featuring the head of a Gorgon....

Virgil imagines the Cyclopes in Hephaestus' forge, who "busily burnished the aegis Athena wears in her angry moods—a fearsome thing with a surface of gold like scaly snake-skin, and the linked serpents and the Gorgon herself upon the goddess's breast—a severed head rolling its eyes",[5] furnished with golden tassels and bearing the Gorgoneion (Medusa's head) in the central boss. Some of the Attic vase-painters retained an archaic tradition that the tassels had originally been serpents in their representations of the aegis. https://en.wikipedia.org/wiki/Aegis
