A South Korean protester holds a flag bearing the portrait of stem-cell scientist Hwang Woo-suk at a rally in Seoul March 22, 2006. Seoul National University officially dismissed a disgraced stem cell scientist on Monday for leading a team that deliberately fabricated key data in two papers once hailed as landmark studies, but since debunked. The slogan on the flag reads,'return Hwang Woo-suk to laboratory'. REUTERS/Kim Kyung-Hoon
