South Korea's top university said yesterday its researchers' claims to have created the world's first cloned wolves are genuine, even though their paperwork was poor.
Seoul National University, still smarting from an earlier cloning scandal, had set up an inquiry after mistakes in an academic paper by the research team were pointed out.
The team, led by Seoul National University veterinary professors Lee Byung-chun and Shin Nam-shik, announced on March 26 it had cloned two female wolves named Snuwolf -- an acronym for Seoul National University wolf -- and Snuwolffy in October 2005.

Lee was also a leading member of the team led by now-disgraced scientist Hwang Woo-suk that produced the world's first cloned dog in early 2005.
The paper on wolf cloning was found to contain incorrect details in a table analysing the mitochondrial DNA sequence of the wolves and their surrogate mother dogs.
The university secured blood and cell samples from three wolves -- the one that provided eggs and the two clones -- as well as from one of the two dogs which also provided eggs for the research.
"DNA analyses by two research institutions showed that the two wolves are clones," Kuk Young, head of the six-member inquiry panel, told journalists.
Kuk said the inaccurate details in the table and another error were "inadvertent mistakes" and not aimed at exaggerating the team's success.
But the panel found that the team did not write a laboratory note when they carried out the research in 2005.
"Materials and documents related to the sampling and analysing of samples were not kept well. It was also found that [the team] lacked the ability to systematically analyze [the research results]," the panel said in a statement.
It said the university would strengthen screening of research papers, focusing on "their academic value rather than news value," before going public with them.
Hwang was hailed as a national hero until a university inquiry ruled in 2005 that some of his work on cloning embryonic human stem cells was fake. He is now on trial.
POLITICAL PRISONERS VS DEPORTEES: Venezuela’s prosecutor’s office slammed the call by El Salvador’s leader, accusing him of crimes against humanity Salvadoran President Nayib Bukele on Sunday proposed carrying out a prisoner swap with Venezuela, suggesting he would exchange Venezuelan deportees from the US his government has kept imprisoned for what he called “political prisoners” in Venezuela. In a post on X, directed at Venezuelan President Nicolas Maduro, Bukele listed off a number of family members of high-level opposition figures in Venezuela, journalists and activists detained during the South American government’s electoral crackdown last year. “The only reason they are imprisoned is for having opposed you and your electoral fraud,” he wrote to Maduro. “However, I want to propose a humanitarian agreement that
ECONOMIC WORRIES: The ruling PAP faces voters amid concerns that the city-state faces the possibility of a recession and job losses amid Washington’s tariffs Singapore yesterday finalized contestants for its general election on Saturday next week, with the ruling People’s Action Party (PAP) fielding 32 new candidates in the biggest refresh of the party that has ruled the city-state since independence in 1965. The move follows a pledge by Singaporean Prime Minister Lawrence Wong (黃循財), who took office last year and assumed the PAP leadership, to “bring in new blood, new ideas and new energy” to steer the country of 6 million people. His latest shake-up beats that of predecessors Lee Hsien Loong (李顯龍) and Goh Chok Tong (吳作棟), who replaced 24 and 11 politicians respectively
Archeologists in Peru on Thursday said they found the 5,000-year-old remains of a noblewoman at the sacred city of Caral, revealing the important role played by women in the oldest center of civilization in the Americas. “What has been discovered corresponds to a woman who apparently had elevated status, an elite woman,” archeologist David Palomino said. The mummy was found in Aspero, a sacred site within the city of Caral that was a garbage dump for more than 30 years until becoming an archeological site in the 1990s. Palomino said the carefully preserved remains, dating to 3,000BC, contained skin, part of the
Young women standing idly around a park in Tokyo’s west suggest that a giant statue of Godzilla is not the only attraction for a record number of foreign tourists. Their faces lit by the cold glow of their phones, the women lining Okubo Park are evidence that sex tourism has developed as a dark flipside to the bustling Kabukicho nightlife district. Increasing numbers of foreign men are flocking to the area after seeing videos on social media. One of the women said that the area near Kabukicho, where Godzilla rumbles and belches smoke atop a cinema, has become a “real
