I really don't know what to say about the headline in this story from the Washington Post.

Embryonic Stem Cell Success
In Mouse Experiment, Cells From Testes Are Transformed

Scientists in Germany said yesterday that they had retrieved easily obtained cells from the testes of male mice and transformed them into what appear to be embryonic stem cells, the versatile and medically promising biological building blocks that can morph into all kinds of living tissues.

If similar starter cells exist in the testes of men, as several scientists yesterday said they now believe is likely, then it may not be difficult for scientists to cultivate them in laboratory dishes, grow them into new tissues and transplant those tissues into the ailing organs of men who donated the cells.

It's almost as though the automatic modifier for "stem cells" must always be "embryonic." This isn't Mr. Weiss's fault -- his story makes it perfectly clear (if you can pass reading comprehension 101) that these aren't embryonic stem cells we're talking about -- but they're like embryonic stem cells in that these adult stem cells can morph into anything. Nope, this is simply what happens when you've got underinformed copyeditors writing headlines.
