question:
American Sage Kotsenburg won gold in the event at the Sochi Games in 2014. We brought him into the âOlympics Cornerâ today for his thoughts on how to watch. Keep scrolling to read that Q&A.
Throughout the Games  weâll occasionally bring someone in to help us better understand the Olympics. Today:  Sage Kotsenburg .
Four years ago in Sochi   Sage Kotsenburg  shocked the snowboarding world by winning slopestyle gold.  He  followed that up with what President Barack Obama told  him  was the âchillestâ interview of the Olympics.  Kotsenburg  has since stopped competing  so  he  wonât be in PyeongChang. But The Post caught up with  him  by phone during a recent film shoot in Italy to get  his  thoughts on this yearâs slopestyle event (8 p.m. Eastern time Saturday on NBCSN).
A: Three people that I would look for are an American kid  Red Gerard.  He âs absolutely crushing it right now. This course  when I saw it  I immediately thought Red can really do well here. I wouldnât be surprised to see  him  on the podium  if not up in the top five.
And then Mark McMorris  who got bronze last time around.  He  came back from a really  really bad injury  so Iâd like to see  him  do good  too. Weâve been good friends for a long time.  He âs crushing it  too.  He âs doing a really  really  really good job right now. Iâd like to see  him  up there.
Iâll give a prediction for gold: Itâs going to be Marcus Kleveland.  He âs from Norway.  He  has pretty much anything you want in a slopestyle course and more. So  if  he  puts down  his  run   he âll probably win or silver  Iâd guess.
answer:
Sage Kotsenburg


question:
"The conventional approach to developing flu vaccines today is one in which we perform surveillance worldwide " said David Topham  director of the New York Influenza Center of Excellence and professor of microbiology and immunology at the University of Rochester in New York.
"We collect the viruses that are circulating in people " said  Topham  who was not involved in the new study . Those viruses then typically are studied in ferrets    he  said.
"We create an antigenic map of each virus and determine how similar or different that is than the (current) vaccine strain  and if it's different enough from the vaccine strain then we select that virus to be in  next year's vaccine " Topham  said. In other words  they make their best guess on what strains will be most likely to spread and cause illness based on surveillance data
On the other hand  the new study suggests "using high-throughput sequencing methods and genetic engineering to rationally design a virus to use as a vaccine "  he  said. "I thought it was a very innovative and comprehensive approach."
The new study acted like "rocket science" compared with the conventional approach used to develop flu vaccines   he  said.
So what does the future hold for flu vaccines and where could this new approach fit in? There has been a shift among researchers around the world to focus on developing universal vaccines   Topham  said.
"These  for influenza  would be vaccines that would last for at least five years and protect against 75% of the viruses that are out there "  he  said. "There are many ways that we might be able to achieve that. This approach that's described in this paper is just one approach."
answer:
Topham


question:
In August  her co-defendant  Anissa Weier  pleaded guilty to attempted second-degree homicide. A jury sided with her arguments and found her not responsible for her actions because she was mentally ill  and she was sentenced to three years in a state mental hospital. Last week  after Geyser's plea hearing   the Leutner family  released a statement: "Though  we  do not believe that an institution is where these attempted murderers belong  the current legal system does not favor victims in this situation." They added: "With this closure  our daughter is a heroic survivor â and no longer a victim."
Geyser and Weier  now 15  were just 12 when they were charged as adults after telling authorities that they tried killing their friend Payton "Bella" Leutner  then 12  in order to become "proxies " or servants  to Slender Man  so that the Jack Skellington-esque Internet meme would not kill them or their families.
It was three years ago last May  the day after Geyser hosted a birthday party  when the girls played hide-and-seek in a forested area near Interstate 94. In Geyser's retelling of accounts to Judge Bohren: "Anissa said that she couldn't do it and that I had to " according to CBS. Geyser "tackled" and stabbed  Leutner  19 times with a kitchen knife  before "Anissa told [Leutner] to lie down so she wouldn't lose blood so quickly  and told her to be quiet  and we left." Geyser and Weier began walking their planned 300-mile trek to Slender Man's mansion in Nicolet National Forest. But  Leutner  eventually crawled out of the forest  where a bicyclist found her and called 911. She survived surgery at a nearby hospital.
At this time of the attack  HBO and Brodsky were brainstorming ideas on the Internet's effects on pre-adolescent brains. As it unraveled  producers emailed an article from The New York Times on the Slender Man to Brodsky  who then found herself in Waukesha County  attending the first court appearances and meeting with both the Geyser and Weier families (the Leutner family declined to participate in interviews for the documentary). Today  when Rolling Stone asks how her impressions of the overall case or girls have changed since then  Brodsky answers  "What I came to discover in the course of making the film  I think the jury in Anissa's case came to discover: These girls were losing their minds in the narrative that was Slender Man. You can't say Slender Man made them crazy  but most kids don't watch Slender Man and go out and kill somebody. You have to look at this through the prism of their mental illness." Brodsky says the girls were involved in "a folie a deux  a delusion shared by two personalities" that allowed them to fall deep into the psychological grip of Slender Man.
answer:

Leutner
