How about Research Complexes. These would be assigned research labs and a research queue like a scientist, however they would also have a scientist assigned to them.
At their simplest, they would just provide a way to set up a research queue without having to worry about the scientist retiring or dying and having to reconfigure the queue. If no scientist is assigned, it just sits idle like the labs would, but assigning a new scientist would make it continue as normal.
A more advanced version would allow multiple scientists and would automatically assign the scientist with the highest total research points for the given project. That way, if the lead dies, someone can automatically take his place. Or if the a backup scientist increases her skill or max labs such that she would do more research with the assigned labs, she would take over.
They wouldn't even have to be a building, necessarily, just a list of assigned scientists, a research queue, and number of labs assigned (obviously they'd still have to all be on the same planet)
