Pyeongchang (South Korea) (AFP)  â American prodigy Nathan Chen  became the first figure skater to land six quads as  he  set an Olympic record in the free skate at the Pyeongchang Winter Olympics on Saturday.
The 18-year-old had bombed on Friday in a nervy short programme that left  him  languishing in 17th place going into the decisive day.
But  Chen  could yet grab a medal after a remarkable free skate that earned  him  215.08 points  one of the highest scores ever seen in the sport.
 Chen  did it on the back of six quads â four rotations in the air â breaking  his  own record of five set last year.
âI have been working on it for a while. Itâs never really fully come together â  Chen  said.
Oh my quad! US skater Chen makes history with six quads

The norovirus is also referred to as the âwinter vomiting bug " Lee-Ann Jaykus  the scientific director for NoroCORE  a food safety initiative thatâs funded through a $25 million grant from the USDA  told Fox News.
The norovirus  which has different strains  can spread easily -- especially in close spaces   Jaykus  said.
When an infected person vomits or defecates  âmassive amounts [of the virus] are excreted â  Jaykus  explained. âThere are millions to billions of particles in one just one gram.â
Food handlers who are sick and donât practice adequate hygiene can easily infect other people. Infected water can also spread the illness  though this more commonly occurs in developing countries   Jaykus  noted.
How do you prevent  it ?
âHand washing is hugely important. In fact  itâs the single most important thing for people attending Olympics." - Lee-Ann Jaykus
âHand washing is hugely important â  Jaykus  said. âIn fact  itâs the single most important thing for people attending Olympics â  she  said.
The norovirus is extremely hard to kill   Jaykus  warned. Inactivating the virus requires a high concentration of bleach. And while itâs easy enough to clean countertops and other similar surfaces with bleach  the same canât be said for carpet and furniture. Alcohol isnât strong enough to entirely kill the virus either   Jaykus  added.
âThe norovirus can be spread for weeks â said  Jaykus   who added that quarantining infected people can also be useful in preventing the spread of norovirus.
âThis is really scary for the athletes -- if you have norovirus you really are incapacitated â said  Jaykus   though no athletes have reported having symptoms of the virus.

If he could n't be the CEO of the whole country , Romney apparently decided that he 'd be the CEO of nothing . 
Romney 's name has surfaced in Utah politics as a potential successor to Sen. Orrin Hatch . 
But it 's pretty clear how someone like Romney would proceed : Audit the finances to get a firm grip on the situation , strike deals with creditors , line up new investors to help fund the region going forward . 
The politics of this might be messy : Romney is not particularly liked by Democrats or Republicans . 
Romney had a long career as a private equity investor and executive at Bain Capital , a discipline that requires the simultaneous application of business engineering and financial engineering to a range of different industries -- and a willingness to resolve huge financial problems by walking away from them or restructuring them .
