Daniel Connolly had an interesting story in our Viewpoint section over the weekend about a lot of the new projects in or around the Medical Center.

St. Jude Children’s Research Hospital has been a big part of the area’s growth, with about $1 billion worth of new construction over the last 10 years.

When St. Jude officials visited with our editorial board a few days ago, they were telling us that one of the new buildings is used to house the laboratory rats the hospital uses in its research.

That’s right. A huge building filled with lots and lots of rats. And it’s not located in Civic Center Plaza.
