Currently the bio-science-pack slot in labs is missing, from the 3 different research labs. Looking into this, it appears to be a syntax error in the buildings.lua file as well as the missing addition to vanilla labs.
For basic laboratory and large laboratory, there was a large tab like space before "bio-science-pack", where as the other packs were just spaces. Removing the single tab like space and replacing it with the similar four regular spaces fixed that issue.
For the vanilla laboratory, just adding a table.insert fixed this issue. (Though the order is wrong and I didn't really try hard enough to figure out how to fix the order, just the building itself.)
This is all for version 1.5.1.
