The most amazing thing about livers is how they can regenerate, if you just give them a chance. They can take a single lobe from a living related donor, and that will keep the recipient alive and grow into a full-sized liver. The donor's remaining liver lobes also grow back into full-size.

I went on an Aleutian Island expedition on a Scripps Institute research ship many years ago, to look at harbor seal kidneys and their reaction to 45 minute dives with no blood flow. The surgeon (and transplant pioneer) I was working for didn't like the fact the seals the Fish and Game hunters were shooting were "going to waste". So he collected some livers along with the kidneys we wanted to study. Then he had the ship's cook prepare them. He and the other chief investigator ate them for dinner. I passed.

But rumaki is actually pretty tasty: That's water chestnut and chicken liver, wrapped in bacon, and broiled. I think the key is a lot more bacon than liver!

We're flying electric helicopters on Mars yet you can't turn on your clothes dryer in Texas. That's because scientists are in charge of Mars, and Republicans are in charge of Texas.
