Alien Commanders can be found on Battleships, or in alien bases. An alien Commander will also always accompany a base invasion force. The Unofficial Strategy Guide incorrectly states that only a Commander from an alien base can be used to give access to "Cydonia or Bust". In practice, any Commander will do -- so long as The Martian Solution has already been researched. Should you research a Commander prior to this, you'll have to capture another.
Individual topics
Researching these topics will not unlock any technologies beyond themselves.
There are also four UFO Components which can be researched but which have no practical value:
A fifth component, Alien Reproduction, cannot normally be found in the game, although it can be researched if you add it to your General Stores using a game editor.
