Why can't humans regenerate lost organs, like, say, your pet newt?

Well, perhaps in the future we can.

"We're not going to be [growing new organs] six months from now, but I am 100 percent confident it will happen in my lifetime," said Dr. Mark Keating, a Harvard Medical School and Children's Hospital researcher, as he described stunning work with mouse cells being published today.

Keating, a cardiologist and cell biologist, said he has forced fully specialized mouse muscle cells to retrace their developmental steps and once again become primitive stem cells, cells with no specialized function ...
