In the Academy, you have the ability to research new technologies. These technologies may improve an existing action, may make new units available to you or can improve certain unit types.

Technologies can be researched with normal resources and an expendable resource called Research Points. For every academy level you build, you get 4 research points which can be used to research even more technologies.
