Lawyers for fallen South Korean scientist Hwang Woo-suk yesterday called for additional tests to verify Hwang's insistence that his stem cell breakthroughs were genuine despite being discredited in a scandal over the falsified research behind them.
As Hwang's lawyers opened their defense in his trial over alleged misappropriation of public and private funds for forged research, they said they want a court order to retrieve samples of what Hwang claims to be the world's first cloned embryonic stem cells.
Seoul National University deemed them to be from mutated eggs, not cloned stem cells, after questions were raised about Hwang's breakthroughs at a university laboratory, which he reported in a 2004 article for the journal Science.
The school has refused to return the samples to Hwang after firing him earlier this year, Hwang's lawyer Jung Keun-hwa said.
"We have a plan to conduct more tests," Jung said in court.
Hwang believes that further tests could show that the samples are indeed genuine cloned stem cells, Jung said.
Hwang has maintained that anything that was falsified in his research results was done by researchers at his laboratory who deceived him into thinking the results were real.
In court yesterday, Hwang said that any allegations that he ordered his researchers to fabricate DNA test results were "a story like a novel."
"I didn't even know the means to fabricate DNA tests," Hwang said, claiming "it was very clear" that his researchers had lied to prosecutors.
He said he had never coerced his researchers into following unethical orders and that his researchers "were not the type of people who would have followed inappropriate orders even if they were told to."
Researchers have testified at previous hearings, however, that they couldn't question or disobey Hwang, who was senior to them.
Hwang is facing charges for allegedly accepting 2 billion won (US$2.1 million) in private donations based on the outcome of the falsified research and of embezzling about 800 million won in private and government research funds. If convicted, he faces at least three years in prison.
Hwang's claims of world-leading advances in the new field of stem cell research were discredited after revelations last year of ethics lapses that culminated in Hwang admitting that forged evidence was used for some of his academic papers.
At the last court hearing last month, lawyers for Hwang's associates facing similar charges began their defense.
Hwang's purported breakthroughs published in leading international science journals had thrust South Korea to the fore of stem-cell research, which some scientists believe could help create innovative new cures for untreatable diseases.
Stem cells are basic cells that can grow into all kinds of tissue, and cloning them could create a way for patients to be treated while minimizing risk of rejection.
It began as a satirical online project. Now millions of young people in India are flocking to it as an outlet for their frustration. A parody political party called the Cockroach Janta Party, with the insect as its symbol, has exploded across India’s social media by turning absurdist humor into protest. Memes and short videos mocking corruption, joblessness and political dysfunction have flooded social media sites, where millions of users are embracing the cockroach — known for its ability to survive harsh conditions — as a tongue-in-cheek symbol of endurance. The online movement’s rise has been unusually rapid. The Cockroach Janta Party (CJP)
SPEAKING OUT: After Siranudh Scott’s allegations surfaced, celebrities and public figures took to social media to share their own experiences of sexual misconduct and abuse A high-profile alleged sexual abuse case within a wealthy Thai beer brewing family has prompted a wave of painful accounts from survivors of unconnected abuse in the conservative nation. Siranudh Scott, a member of the billionaire Thai family that founded the ubiquitous Singha beer brand, posted an emotional video this month accusing his elder brother Sunit of repeatedly abusing him when he was a teenager. Sunit, who is in his 30s, later denied the allegations in a video posted online, but Singha parent Boonrawd dismissed him from his executive role with the company on Tuesday last week. “I felt I needed to speak
A Hong Kong astronaut is to join a Chinese space mission for the first time as part of a three-person crew launching today, as Beijing edges closer to its goal of landing people on the moon. The Tiangong space station — crewed by teams of three astronauts that are typically rotated every six months — is the crown jewel of China’s space program, boosted by billions in state investment in a bid to catch up with the US and Russia. The Shenzhou-23 mission is to blast off at 11:08pm from the Jiuquan Satellite Launch Center in northwestern China, carrying three astronauts to
UPGRADED ALERT: The risk inside DR Congo is now considered ‘very high,’ while neighboring countries face a ‘high’ threat as the outbreak continues, the WHO said Ebola is spreading faster than responders can track it in eastern Congo, where health workers managed to follow up with barely one in five identified contacts in a single day. Authorities in the Democratic Republic of the Congo (DR Congo) reported 83 confirmed infections, 746 suspected cases and 1,603 identified contacts as of Thursday, but health workers were able to follow up on only 342 contacts that day — about 21 percent of the total under monitoring — data released by the DR Congo Ministry of Public Health on Friday showed. The figures suggest the response is falling behind the outbreak itself,
