It's just a Rank-5 for the "Science!" perk. I have not seen other perks that did this other than the Gun-Nut Rank 5, so i took the initiative. Basically it just adds a Rank 5 for the Science!, used for custom resources found that which requires this. 

It does not do many things by itself as it is used with mods, although it has a 2nd version that which adds +2% damage per level, with up to 10% at Rank 5.

Hopefully this would be the standard used in many mods to prevent conflicts.
