This is a great article and I feel like the headline doesn't even do it justice. I'd love to read something more in-depth (a book, even) on the trial-and-error approach the researchers went through to find everything affecting the tuna in captivity. I was amazed that this species is even alive, especially with this quote: "in the wild, only one in tens of millions becomes an adult."

One thing that did bother me, though, was the WSJ's presentation of the pictures -- I had huge white gaps between all of the pictures and kept wondering if I was missing content.
