[EX Q]: A top engineering executive at Facebook announced Thursday night that  she 's leaving the company to work on shrinking a powerful medical technology.
 Mary Lou Jepsen   Facebook's executive director of engineering and the head of display technologies at Oculus â the social network's much-ballyhooed virtual reality product â made public  her  upcoming departure in August during a keynote talk in Silicon Valley.
"I have decided to leave Facebook and Oculus to work on curing diseases using some new imaging technologies I've been incubating for awhile  " Jepsen  said at the Anita Borg Institute's Women of Vision awards  an organization which describes  her  as "one of the world's foremost display innovators."
Additionally   Jepsen  said  she 's joined the board of directors of a "$20 billion automotive company that's listed on the New York Stock Exchange " adding that's  she 's "really interested to participate in helping steer the transformation of transportation."
A little more than a year ago   Jepsen  left Google's secretive research laboratory to work on Facebook's Oculus headset technologies. Prior to that   she  co-founded One Laptop Per Child  an organization that aims to make inexpensive computers and give them to children in developing nations.
 Jepsen  told the crowd Thursday night that  she  wants to shrink down magnetic resonance imaging (MRI) â machines used to image brain activity and normally fill an entire hospital room â into affordable  wearable consumer devices.
To that end   she  showed an image on stage of  her  vision  which is to essentially bring all of this tech into something that looks like a ski hat.
 Jepsen  teased a few possible applications of such a device  including to help treat cancer  cardiovascular disease  mental disorders  and neurodegenerative diseases. And in a bizarre twist   she  also said  her  concept might enable people to communicate with their thoughts.
It's uncertain exactly what the shrunk-down MRI technology might be called  how it might work  how far along in development it is  or if any of the applications  she  mentioned are even possible.
"I think that's the point of what we all should all be doing "  she  said. "Trying to make the impossible  possible."

The Democratic Congressional Campaign Committee is taking fire from the left after months of relative peace  thanks to a document put online the night of Feb. 22 â a collection of opposition research on  Laura Moser   a progressive candidate in Texasâs competitive 7th Congressional District.
As  Moser  was attending a campaign event  the DCCC posted a short but brutal collection of hits on  Moser  that would be likely used against  her  if  she  won the Democratic nomination. The 7th District is one of 23 where Hillary Clinton outpolled Donald Trump in 2016  while voters sent a Republican congressman to Washington.
âDemocratic voters need to hear that  Laura Moser  is not going to change Washington â the committee wrote. â She  is a Washington insider  who begrudgingly moved to Houston to run for Congress.â
 Moser  responded later Thursday night  saying in a statement that the DCCCâs tactics represented âwhy people hate politicsâ and hurt the effort to take Congress back from Republicans.
âWeâre used to tough talk here in Texas  but itâs disappointing to hear it from Washington operatives â  she  said.
 Moser  did relocate to  her  native Houston last year and began running for Congress  with  her  move back home â after launching Daily Action  a campaign tool for progressives frustrated by Trump â as part of the story. The DCCC  which has seen plenty of candidates brought down by residence issues  came to view  her  as unelectable.
âVoters in Houston have organized for over a year to hold [Republican Rep. John Abney] Culberson accountable and win this Clinton district â said DCCC communications director Meredith Kelly. âUnfortunately   Laura Moserâs  outright disgust for life in Texas disqualifies  her  as a general election candidate and would rob voters of their opportunity to flip Texasâs 7th in November.â
The DCCCâs memo hit  Moser  for paying Revolution Messaging  the firm where  her  husband  Arun Chaudhary  had worked since 2012  to produce  her  TV ads. But its main attack lines were backed up by an article  Moser  wrote for Washingtonian in 2014  where  she  joked that  she âd âsooner have my teeth pulled out without anesthesiaâ than move to  her  grandparentsâ home in Paris  Tex. Paris is a small city more than 300 miles from the 7th District; the DCCC warned that voters would not process the nuance.
Both  Moser âs campaign and the DCCC saw  her  in a strong position to win one of two runoff slots in the March 6 Democratic primary. With early voting underway  and Democratic turnout in Houstonâs Harris County undergoing a historic surge  the DCCC pounced.
But the way it did so  advertising what Republicans might use to beat  Moser   sparked outrage across the left. At Daily Kos  a popular group blog that crowdfunds for Democratic candidates  a diarist wondered whether the move against  Moser  âmay have something to do with the candidate selection role the Blue Dog Coalition is playing at the DCCC.â The People for Bernie Sanders  a progressive group organized to support the Vermont senatorâs 2016 presidential campaign  called âfor the DCCC board to investigate how the decision was reached and publish the findings publicly.â There was an additional factor: Revolution Messaging had worked for Sanders  and Chaudhary had worked as the campaignâs photographer.
 Moser  is not the only progressive candidate in the district primary  and several of  her  rivals back universal Medicare  which has become a litmus test on the left. But  her  race has attracted national attention as an example of progressive candidates bristling as well-established Democratic organizations backed their rivals. On Thursday morning  the Intercept  which has been publishing articles on how the DCCC works  highlighted  Moser âs race and the involvement of Emilyâs List with party donor Lizzie Pannill Fletcher.

[EX Q]: Says he âprobablyâ has âa very good relationshipâ with  Kim 
President Donald Trump refused to say whether he has spoken directly with North Korean leader Kim Jong Un in an interview on Thursday  but said he âprobablyâ has âa very good relationshipâ with the dictator.
âI donât want to comment on it â Trump told the Wall Street Journal after he was asked directly if he had spoken with  Kim . âIâm not saying I have or havenât. I just donât want to comment.â
Direct talks between the U.S. president and  Kim  would be unprecedented. No conversation has been publicly reported between any sitting U.S. president and a North Korean leader in decades  if ever.
Trumpâs relationship with  Kim  has been primarily distinguished by escalating barbs and insults. North Koreaâs aggressive pursuit of a ballistic missile capable of hitting the U.S. with a nuclear warhead has emerged as the presidentâs most fraught foreign crisis.
Trump has mocked  Kim âs weight and called him âlittle rocket manâ in a speech to the United Nations General Assembly. He quipped on social media last week that the ânuclear buttonâ on his desk was larger than that of the North Korean leader.  Kim  has dismissed Trump as a âdotardâ and âfrightened dogâ in public statements.
White House spokespeople didnât immediately respond to questions about whether Trump and  Kim  had spoken.
Trump has said North Korea wonât be allowed to develop a nuclear missile capable of striking the U.S.  and has threatened war if economic sanctions and negotiations canât avert  Kim âs ambitions for such a weapon.
 Kim  has vowed never to give up  his  countryâs nuclear weapons  regarding them as  his  last line of defense against a U.S. invasion. Technically  South Korea and the U.S. remain at war with North Korea after the Korean War ended in 1953 with an armistice instead of a peace treaty.
