It's part of God Emporer's mod (assuming you have installed his techarea.txt which I think he includes with those two races). He has these two empty filler techs to help the AI arrange it's research better, they cost like 2 pts to start with so they don't get very expensive. If you get his entire mod he has a better explantion than what I can provide, since I don't quite understand it myself. Or you can ask him, he Posts fairly frequently.
