South Korean scientists have discovered ways to prevent monkeys rejecting organ transplants from pigs, paving the way for the use of animal organs and cells in humans, the Korea Times reported yesterday.
The ground-breaking research raises new hopes for millions of people needing heart, liver and kidney transplants, the English-language newspaper said.
The study was led by Hwang Woo-suk, a Seoul National University professor whose team of experts manufactured stem cells by cloning human embryos using human eggs from donors and skin cells from patients.
The stem-cell research announced last week marked a step forward in efforts to make it possible one day to transplant healthy cells into humans to replace cells ravaged by illnesses such as Parkinson's and diabetes.
The Korea Times quoted one of Hwang's fellow researchers, identified only as Kim, as saying the researchers are hoping to transplant hearts and insulin-producing cells from cloned miniature pigs into monkeys by the end of the year.
"We have created dozens of pigs embedded with human immunity genes since late last year. We plan to start transplanting their organs or cells into monkeys as early as late this year," Kim said.
The organs of pigs are almost the same in size as those of humans and their metabolic functions are also similar, he added.
Four people jailed in the landmark Hong Kong national security trial of "47 democrats" accused of conspiracy to commit subversion were freed today after more than four years behind bars, the second group to be released in a month. Among those freed was long-time political and LGBTQ activist Jimmy Sham (岑子杰), who also led one of Hong Kong’s largest pro-democracy groups, the Civil Human Rights Front, which disbanded in 2021. "Let me spend some time with my family," Sham said after arriving at his home in the Kowloon district of Jordan. "I don’t know how to plan ahead because, to me, it feels
The collapse of the Swiss Birch glacier serves as a chilling warning of the escalating dangers faced by communities worldwide living under the shadow of fragile ice, particularly in Asia, experts said. Footage of the collapse on Wednesday showed a huge cloud of ice and rubble hurtling down the mountainside into the hamlet of Blatten. Swiss Development Cooperation disaster risk reduction adviser Ali Neumann said that while the role of climate change in the case of Blatten “still needs to be investigated,” the wider impacts were clear on the cryosphere — the part of the world covered by frozen water. “Climate change and
Poland is set to hold a presidential runoff election today between two candidates offering starkly different visions for the country’s future. The winner would succeed Polish President Andrzej Duda, a conservative who is finishing his second and final term. The outcome would determine whether Poland embraces a nationalist populist trajectory or pivots more fully toward liberal, pro-European policies. An exit poll by Ipsos would be released when polls close today at 9pm local time, with a margin of error of plus or minus 2 percentage points. Final results are expected tomorrow. Whoever wins can be expected to either help or hinder the
DENIAL: Musk said that the ‘New York Times was lying their ass off,’ after it reported he used so much drugs that he developed bladder problems Elon Musk on Saturday denied a report that he used ketamine and other drugs extensively last year on the US presidential campaign trail. The New York Times on Friday reported that the billionaire adviser to US President Donald Trump used so much ketamine, a powerful anesthetic, that he developed bladder problems. The newspaper said the world’s richest person also took ecstasy and mushrooms, and traveled with a pill box last year, adding that it was not known whether Musk also took drugs while heading the so-called US Department of Government Efficiency (DOGE) after Trump took power in January.
