[EX Q]: Shaun White Wins Gold In Halfpipe At The Winter Olympics
Updated at 10:15 p.m.  ET
Shaun White  pulled off a gold-medal comeback in the halfpipe  and Japan's Ayumu Hirano won silver on the strength of a phenomenal second run.
CORRECTION: An early version of this story reported that  White  had won silver — that was reported after the second run had completed. On his third run   White  won gold.
 White  missed out on a medal back in 2014  when  he  was hurt at the Sochi Games.  He 's now the only snowboarder ever to win three gold medals at the Olympics. And  he  did it by winning the 100th gold medal for the U.S. Winter Olympic team.
After the Japanese snowboarder's rousing run  the pressure shifted to James and  White . James seemed to take a very deep breath before he set off on his second run. The first section was great — but he couldn't get a clean landing on one of his final tricks.  White  came out with energy and speed — but  he  fell midway through  and mustered only 55 points.
The situation reversed in the third and final run  when  White  earned a 97.75 and both of  his  top rivals fell during  their  attempts.
This is the second Olympic medal for Hirano; he won silver in Sochi. He is also the reigning X Games champion in the halfpipe  having won that title last month  in a competition that  White  skipped.
 White  led a group of four American snowboarders who qualified for the finals of the men's halfpipe at Phoenix Snow Park in Pyeongchang; joining  him  were Ben Ferguson  Chase Josey  and Jake Pates.
 Ferguson  cleaned up  his  second run after a fall in the first. And after a strong final run earned  him  a 90.75   he  finished 4th; Josey was 6th and Pates was 8th.

[EX Q]: Goldsmith Akis Goumas  is currently attempting to replicate the stone in hard wax or burnt clay to understand the movements  shape and size of the handheld tools used.
In tracing the tool marks on the sealstone   Goumas  speculates that the craftsman may have used a rotating wooden lathe with a sharp edge to engrave the stone.
 He  thinks one artisan did the basic  three-dimensional engraving while another completed the secondary work.
"It isn't one craftsman's work because we can see different qualities of dexterity in the synthesis "  he  told CNN over email.
While  Goumas  may soon have answers as to how  it  was fashioned 3 500 years ago  Stocker says we will probably never know how  it  came into the Griffin Warrior's possession.

[EX Q]: Nathan Chen  hit the ice jumping when  he  landed in PyeongChang  South Korea to compete in  his  first Winter Olympic Games. Despite not sleeping through the night because of jet lag  the young American star managed to skate all three practice sessions to which  he  was assigned and  he  held little back  landing most of the challenging quadruple jumps for which  he âs known.
That bodes well for the first member of the U.S. Olympic figure skating team scheduled to compete in PyeongChang.  Chen   18  will skate the short program portion of the team event this Thursday  Feb. 8  at 8pm ET  a day before the official Olympics opening ceremony on Feb. 9.
Itâs a moment  Chen  was all but groomed for. When  he  was seven   Chen  used to perform a routine set to âI Just Canât Wait to be Kingâ from the Lion King  decked out in a Simba costume with hoodie  ears and tail that  his  mother made for the occasion. Few could have predicted how prescient it was.
 Chen  is now the two-time U.S. national figure skating champion and is known as the Quad King for being the first skater in the world to land five quadruple jumps in a single program. Most elite figure skaters perfect just one or two of the four-rotation jumps. But  Chen âs ability to whip off five different quad jumps makes  him  a favorite to win individual Olympic gold in PyeongChang.
A native of Salt Lake City and the youngest of five   Chen  displayed  his  extraordinary skating skill from an early age  landing  his  first triple jumps at 10. Mastering quad jumps was an extension of the work ethic instilled by  his  parents  who immigrated from China. âMy parents always wanted the very best from me  and pushed me further and further â  Chen  tells TIME. âThat stuck with me  and itâs something Iâve taken hold of  myself  and tried to improve on.â
As a rising junior figure skater   Chen  noticed a âdry spellâ in menâs skating in the U.S. during which there âhasnât been too much motivation to do quad jumps â  he  says. (A U.S. manâs last Olympic skating medal was Evan Lysacekâs gold in 2010.) âI was seeing younger guys at international competitions do crazy things  and realized we were a little far behind  and that we needed to keep pushing forward.â
Watching a competitor from China packing his figure skating programs with three quad jumps sparked a competitive fire in  Chen . âKnowing that other guys were far ahead of  me  switched a light on in my head  that it was really important to get these quad jumps â  he  says.
Trained in ballet and gymnastics along with skating   Chen âs strength and technique offered a strong foundation for building  his  repertoire of quad jumps.  His  training partner and Olympic teammate  Adam Rippon  says  Chen  is âone of the best jumpers in the worldâ and credits  Chen  with improving  his  own figure skating.
 Chen  is also among the most versatile.  His  programs seem to be a continuous work in progress â this season  he  has not performed the same long program twice  switching up  his  figure skating jumps depending on how  he  is feeling physically and compensating for any mistakes  he  may have made. Because  he  is able to execute five different quadruple jumps (not to mention their triple versions too)   he  has a range of tricks  he  can slide into  his  routines. âIâm the only skater currently who can do all five quads. So having that technical difficulty in my arsenal allows me to manipulate my program however I want during competition.â
The downside of all that flexibility (and sheer physical force) is the toll it can take on  his  body. Just after winning  his  first medal  a bronze  at the senior U.S. national championships in 2016   Chen  injured  his  hip  forcing  him  to spend five months off the ice to recover.
Once back in the rink   Chen  focused on soaring even higher. âI never set out to do these programs  or to make history â  he  says. âI just like to keep pushing  myself  and the sport.â
