Countdown to Beijing 2022******

BEIJING, Nov. 15 (Xinhua) -- With the 2022 Winter Olympics 80 days away, organizers have begun to make artificial snow at the National Alpine Skiing Center for the event.。

The National Alpine Skiing Center located in the Yanqing competition zone is set to host the Alpine skiing competitions at Beijing 2022.。

Wu Gaosheng, an operation manager at the National Alpine Skiing Center, said that the snowmaking work is expected to last until mid-January.。

A series of water-conserving and recycling designs have been put into place to optimize water usage for snowmaking, human consumption, and other purposes, according to the Beijing 2022 organizing committee.。

Around 90 percent of snow used at the Alpine skiing venue for the Pyeongchang 2018 Winter Olympics was reportedly artificial, while artificial snow was also a feature of Vancouver 2010 and Sochi 2014.。

The National Alpine Skiing Center is the first Olympic-standard alpine ski venue in China with a maximum vertical drop of about 900 meters. It has seven slopes. Enditem。

World's first pig******

The world's first person receiving a heart transplant from a genetically-modified pig two months ago has died, the US Maryland hospital that performed the surgery announced Wednesday.

David Bennett, the 57-year-old American patient, died Tuesday at the University of Maryland Medical Center (UMMC). Doctors did not give an exact cause of death, saying his condition had begun deteriorating several days earlier.

After it became clear that he would not recover, Bennett was given compassionate palliative care. He was able to communicate with his family during his final hours, said the UMMC in a release.

Bennett received the first-of-its-kind transplant on January 7, and lived for two months following the surgery. He had been deemed ineligible for a conventional heart transplant, and the surgery was the only currently available option for him, according to the UMMC.

The US Food and Drug Administration granted emergency authorization for the surgery on New Year's Eve through its expanded access (compassionate use) provision.

After the surgery, the transplanted heart performed very well for several weeks without any signs of rejection, according to the UMMC.

Bennett was able to spend time with his family and participate in physical therapy to help regain strength. He watched the Super Bowl with his physical therapist and spoke often about wanting to get home to his dog Lucky, according to the hospital.

Bartley Griffith, who performed the groundbreaking transplant, said Bennett proved to be a brave and noble patient who fought all the way to the end.

"As with any first-in-the-world transplant surgery, this one led to valuable insights that will hopefully inform transplant surgeons to improve outcomes and potentially provide lifesaving benefits to future patients," Griffith said.

"We have gained invaluable insights learning that the genetically modified pig heart can function well within the human body while the immune system is adequately suppressed," said Muhammad Mohiuddin, professor of surgery and scientific director of the Cardiac Xenotransplantation Program at the University of Maryland School of Medicine.

"We remain optimistic and plan on continuing our work in future clinical trials," he said.

About 110,000 Americans are currently waiting for an organ transplant, and more than 6,000 patients die each year before getting one, according to US government data.
