Six cloned male golden Labradors named Toppy look set to be sniffing suitcases for the Korean Customs Service. The cloning method was developed by a team at Seoul National University led by Lee Byeong-chun, former lieutenant of disgraced scientist Woo-Suk Hwang, who was found to have fabricated research. Their father was chosen due to his exceptional drug sniffing abilities and good temperament. While still a ways off from sniffing out contraband, the six Toppies have already passed the first of round of genetic and behavioral testing and look set to continue the family tradition. As long as they can keep their noses out of passengers' crotches, they should be fine. [Chosun via Far East Gizmos and The Niche]
