The game makes it clear that labs and workshops get a bonus when built next to buildings of the same type. I've also seen it written online that Satellite Uplinks get a bonus but I can't see anywhere what it is.
What are all the buildings that get bonuses, and what are those bonuses? Supplemental question: Does "adjacent" mean horizontal or also vertical adjacency?

The types and adjacency bonuses are as follows:
Note that if you go into the Build Facilities screen, you can see this in the description text (of the currently highlighted facility), but sometimes you have to sit there and wait for it to start scrolling.
