Uh, so did Dr. Young do his own experiments or copy the data, that's the real question. However, this is an important question. If he just copied it and presented it, we lose valuable verification.

I really hope that he did, and didn't just duplicate the work. It's perfectly normal to have another study to validate the original. That's not plagiarism, it's peer review/verification and is a normal part of the scientific review process.

I agree with DrunkT - doesn't matter who did it, as long as it's the truth. Facts don't care about being copyrighted or copied, they're still either true or false regardless.
