Here is a Wired Science writeup of that article I posted yesterday. It's less detailed, but it's easier to read. Again, the top story is that researchers have found a new way to harvest stem cells from embryos without destroying them: taking a cell at the four-cell stage produces cell lines that don't need to be co-cultured. And we already know from fertility treatments that the remaining three cells can grow into healthy children.
