When the Vegas Golden Knights selected  Deryk Engelland  in the expansion draft and signed  him  to a one-year deal  the longtime Las Vegas native set out to earn another contract.
 Engelland  got  it  Monday with a $1.5 million  one-year extension that serves as a reward for the veteran defenseman enjoying  his  best NHL season at age 35.
“That’s a dream come true ”  Engelland  said. “I’m getting a little older now and to be able to stay here at home and play another year  that’s your whole goal going into the season and I couldn’t be more happy.”

 Engelland  is averaging almost 20 minutes a night and has three goals and 10 assists for 13 points through 41 games. General manager George McPhee said  “Deryk has been an integral part of our team  on and off the ice  from the very beginning.”
 Engelland  has always been somewhat of a tough guy and came into the season with 500 penalty minutes in 469 games with the Pittsburgh Penguins and Calgary Flames.  He  has just 16 this season and has show  he  has more to  his  game than that.
Roy added that  Engelland  and coach Gerard Gallant having similar personalities helped them get and stay on the same page.  Engelland  is the blue-collar  veteran leader on a young team  while Gallant is the front-runner for the Jack Adams Award as coach of the year.
 Engelland  fell in love with Las Vegas while playing for the ECHL’s Wranglers from 2003-2005  and  he  and  his  wife  Melissa  still call  it  home.  He  was thrilled when McPhee approached  him  about an extension that gets  him  a raise from  his  current $1 million salary and about the Golden Knights’ success thus far.

[EX Q]: "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."

[EX Q]: As the U.S. Senate prepares to vote on multiple versions of Republican health care repeal bills early next week -- which is anticipated to include a devastating amendment offered by Sen. Ted Cruz -LRB- R-Texas -RRB- -- it is critical that we are responsible and transparent when evaluating policy that will impact one sixth of our economy and millions of families across the country . 
HHS compares premiums for a 40 year old under the Cruz proposal to an "enrollment weighted average" premium under the ACA . 
HHS offers no estimates for the out-of-pocket costs that patients would bear for the "essential services" not covered by Cruz 's plans . 
To begin with , the report claims that the Consumer Freedom Amendment -LRB- Cruz amendment -RRB- to the Senate Better Care Reconciliation Act -LRB- BCRA -RRB- would miraculously lead to more people covered and lower premiums . 
HHS 's results also rely on assumptions about consumer behavior , including who will buy ACA-compliant or Cruz plans by income , age , and risk . 
Cruz plans have high deductibles and barely-there coverage .
