Another high-profile 'Science' paper withdrawn

If something gets published in a prestigious journal like Science, does that mean it's necessarily true?

Here is more evidence to the contrary:

Woo Suk Hwang, the South Korean cloning scientist who publicly admitted in late November to having obtained human egg cells unethically, has now also moved to have his initial paper withdrawn because many of the scientific achievements claimed within it are false.

Hwang has now admitted that the paper he co-authored had "fatal errors" in it, and that the prestigious journal Science should withdraw it...

Check out this paragraph:

Roh, who was one of the co-authors of the paper in Science, has now also admitted that he was not even aware of the paper until it appeared in the journal. Roh justified the fact that he authored a paper he was not aware of by stating that "security concerns" demanded such secrecy even within the group of authors.
