Winter Olympics

"The Sustainability and Legacy Games" is a phrase that appears regularly, as well as being written on all official communications and documents.

The sustainability aspect comes from the organiser's commendable aim to be 100 percent carbon neutral, using carbon dioxide refrigeration techniques, low-carbon transport options and the use of existing venues from the last Games.

Beijing's Summer Games unveiled some of the most spectacular venues in Olympic history.

Bobsledder Nadezhda Sergeeva tested positive for a heart drug on February 18, five days after a previous doping test returned a negative result for her, the Bobsleigh Federation of Russia said in a statement on Friday.

"On February 13, her sample was clean. The team's medical staff did not prescribe the drug to the athlete," the federation said in a post on its official Facebook page.

The court said no hearing date had been fixed yet and no further information would be provided for the moment.

Krushelnitsky, who competes in curling, is suspected of testing positive for meldonium, a banned substance that increases blood flow and improves exercise capacity.

Krushelnitsky, who won bronze with his wife in mixed-doubles curling in Pyeongchang, has not responded to a request for comment.

Russia's curling federation has also launched an "emergency commission" to investigate the doping case, federation president Dmitry Svishchev told Reuters.

The 22-year-old had just started her short dance routine at the Winter Olympics when her dress came undone, leaving her breast exposed.

Papadakis "felt it right away and prayed", continuing her routine with partner Guillaume Cizeron to deliver a performance that leaves them in second heading into Tuesday's free dance.

"It was pretty distracting," she said.

"My worst nightmare at the Olympics. I told myself 'you have to keep going'.

"That's what we did, and we have to be proud of ourselves, delivering a great performance with that happening."

Competing in only his sixth major race, the 34 year-old completed his run in 56 minutes and 41 seconds.

Pita Taufatofua, who took up cross-country skiing just over a year ago, finished ahead of four other competitors in South Korea, and more than 23 minutes behind the gold medallist, Dario Cologna from Switzerland.

Head of Sport for the Royal Tonga Ski Federation, Steve Grundmann, said it was a fantastic race by the double Olympian.

He said Pita Taufatofua paced his way perfectly around a difficult course and even had a smile on his face.

The teen from Southern California with an effervescent personality and a prodigious talent has gone pretty rapidly from a rising star in her sport to an instantly recognisable celebrity in the US and South Korea.

And now with a shiny Olympic gold medal around her neck, her fame will surely only soar higher into the stratosphere.

If there were any doubts that Kim would be able to produce on the biggest stage, or that the pressure might get to her, she dispelled them with a breathtaking first of three runs in the halfpipe final on Tuesday, which scored her 93.75.

Pita Taufatofua emerged from the tunnel covered in his trademark body oil and wearing a grass skirt, sandals and a huge smile as he led the Tongan delegation around the arena.

"I won't freeze. I am from Tonga. We sailed across the Pacific. This is nothing," Taufatofua said.

The Oceania gold medallist in taekwondo made global headlines in 2016 with a shirtless entrance as the country's flagbearer at the Rio Olympics.

The good news for his admirers is that he returned for the Winter Olympics, having switched to cross country ski-ing.

Chefs for the 109-member team meant to buy 1,500 eggs, but ordered from a local supermarket using Google Translate and had egg on their faces when the produce arrived.

"The eggs was more like a misunderstanding than something that we needed, so it was an extra zero on the orders, so 1,500 to 15,000," Norwegian chef de mission Tore Ovrebo said.

"They will probably use them I guess and I don't know, maybe the people that supplied us with them will take them back I don't know. It's not a big issue."

Taufatofua lost 15kg as he adapted his body and learned a new sport, and is now able to compete in the Winter Olympics.

He made his name after finding recognition as the oiled flagbearer for Tonga at the Rio Olympics in 2016.

The 34-year-old crashed out in the first Round at Rio, but has spoken of his pride at being able to compete again:

"After Rio I decided to find the hardest sport possible because I needed a new challenge.

"You've got to put your body through something really challenging and the goal was to do it in one year - and we did it in one year!"

They also agreed to field a joint women's ice hockey team in rare talks at the truce village of Panmunjom.

These are the first high-level talks between the countries in more than two years.

It marks a thaw in relations that began in the new year when North Korea offered to send a team to the games.

The games will take place between 9 and 25 February in Pyeongchang in South Korea.
