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.
Drug lord Jose Adolfo Macias Villamar, alias “Fito,” was Ecuador’s most-wanted fugitive before his arrest on Wednesday, more than a year after he escaped prison from where he commanded the country’s leading criminal gang. The former taxi driver turned crime boss became the prime target of law enforcement early last year after escaping from a prison in the southwestern port of Guayaquil. Ecuadoran President Daniel Noboa’s government released “wanted” posters with images of his face and offered US$1 million for information leading to his capture. In a country plagued by crime, members of Fito’s gang, Los Choneros, have responded with violence, using car
OVERHAUL: The move would likely mark the end to Voice of America, which was founded in 1942 to counter Nazi propaganda and operated in nearly 50 languages The parent agency of Voice of America (VOA) on Friday said it had issued termination notices to more than 639 more staff, completing an 85 percent decrease in personnel since March and effectively spelling the end of a broadcasting network founded to counter Nazi propaganda. US Agency for Global Media (USAGM) senior advisor Kari Lake said the staff reduction meant 1,400 positions had been eliminated as part of US President Donald Trump’s agenda to cut staffing at the agency to a statutory minimum. “Reduction in Force Termination Notices were sent to 639 employees at USAGM and Voice of America, part of a
Canada and the EU on Monday signed a defense and security pact as the transatlantic partners seek to better confront Russia, with worries over Washington’s reliability under US President Donald Trump. The deal was announced after a summit in Brussels between Canadian Prime Minister Mark Carney and European Commission President Ursula von der Leyen and European Council President Antonio Costa. “While NATO remains the cornerstone of our collective defense, this partnership will allow us to strengthen our preparedness ... to invest more and to invest smarter,” Costa told a news conference. “It opens new opportunities for companies on both sides of the
The team behind the long-awaited Vera Rubin Observatory in Chile yesterday published their first images, revealing breathtaking views of star-forming regions as well as distant galaxies. More than two decades in the making, the giant US-funded telescope sits perched at the summit of Cerro Pachon in central Chile, where dark skies and dry air provide ideal conditions for observing the cosmos. One of the debut images is a composite of 678 exposures taken over just seven hours, capturing the Trifid Nebula and the Lagoon Nebula — both several thousand light-years from Earth — glowing in vivid pinks against orange-red backdrops. The new image
