This brass object helped scientists model the double-helix structure of DNA. It's on display in our "American Stories" exhibition. Tweeters asked us to change the object's label to include the name of scientist Rosalind Franklin--and we did. It wasn't included originally due to space constraints, but we were able to re-arrange a bit and include her. (If you've seen the exhibition, you know it's a series of snapshots in history with very little text.) We can't always make modifications like this onebut we DO listen to audience feedback and appreciate it when you share your ideas and comments.
