So far not a single embryonic stem-cell has done anything for anybody.
Not likely to do so anyway. Seems that to use them you have to turn them into adult stem-cells.
We got adult stem-cells coming out our ears (and everywhere else), and they do stuff.
In the 1830s/40s Canals were all the rage in the then partially settled Ohio Valley. Canal building bankrupt those states and forced them to write entirely new constitutions with re-constituted governments. This is something long overdue for New Jersey, but after they've run the debt up $40 billion to $95 billion, they may decide to get a handle on their runaway government.
I just hope none of them want to move here.
