Taking responsibility, that is. Hwang Woo-Suk has admitted a part in the faking of cloning research in his lab. A part, that is, as he still maintains that the actual faking was done by underlings.
This is rather disingenuous. Either he was in charge of his lab or he wasn't. If he was genuinely supervising his research staff, he should have known what they were doing. Giving 'specific orders' is neither here nor there. If he didn't know what they were doing he obviously wasn't involved enough in the work to claim the credit for it.
