The Zeus Genetics was a medical research institute where secretly alien-human hybrid babies were brought to the world. (TXF: "Per Manum", "Essence"). The institute's leading doctors were Dr James Parenti (who was Scully's gynecologist), Dr. Lev and Duffy Huskell. Research was originally sponsored by the Syndicate. After the collapse of the organization in 1999, Zeus Genetics continued its activities until 2001, when alien replicant Billy Miles had killed all three leading doctors and destroyed the research results. The institute secretly watched Scully's pregnancy. One doctor at the Institute, Dr. Lizzy Gill, said Scully's child was very special and wanted bring to world babies like him.
