Q: After four years of taunting and torturing fellow Republicans , Ted Cruz is shedding his just-say-no persona in the Senate for a new identity : Team player . 
Majority Leader Mitch McConnell -- a man Cruz once derided as a liar and an ally of Democrats -- is counting on the Texan to help navigate an Obamacare repeal bill through the Senate with virtually no margin for error . 
As a trusted voice of the conservative wing of the GOP and conduit to the House Freedom Caucus , Cruz is fast emerging as a pivotal player in the Republican bid to do away with the landmark Democratic health care law . 
But after receiving so much blowback for that and many other episodes , there 's nary a Cruz critic in the Senate Republican Conference nowadays . 
Cruz 's work on health care has been uncharacteristically low profile so far . 
It began with a private dinner in mid-February at the upscale D.C. steakhouse Capital Grille with the more compromise-minded Alexander , who once chided Cruz for calling McConnell a liar on the Senate floor by noting that one thing "you learn in Kindergarten is to respect one another ." 
Alexander and Cruz agreed to assemble a group of GOP senators to prepare for the eventuality that the House would send them a health care bill riddled with flaws that could not pass the Senate as written . 
But when it comes to passing a new health care law , Republicans believe the inclusion of Cruz and his close ally , Sen. Mike Lee -LRB- R-Utah -RRB- , could pay critical dividends by building support among conservative groups and the House Freedom Caucus . 
"One of the challenges when the Obamacare bill was in the House , was that early on was that the different parts of the party were not talking to each other ," Cruz said in an interview in his office . 
Collaborative and inclusive are not typically words associated with Cruz . 
Now that President Barack Obama is out of office , Cruz said his mission in the Senate is no longer to be the "loyal opposition ." 
"Different circumstances call for different approaches ," said Cruz , who is gearing up to run for a second term next year in a closely watched race . 
Cruz 's leading role has shocked some of his colleagues . 
The group that Cruz helped develop is , in some ways , a substitute for the traditional committee process . 
"We have skin in the game ," Cruz said . 
Still , there 's concern among some more centrist senators that the end-product could appeal too much to Cruz and not enough to the dozen or so Republican senators who have grave concerns about slashing Medicaid and removing protections for preexisting conditions . 
Clearly he believes Lee and Cruz are crucial ; but some GOP sources said there are deep doubts among senators that Collins or Sen. Rand Paul -LRB- R-Ky . -RRB- 
Though GOP leaders believe by getting Cruz involved they are minimizing the possibility that Cruz will later demolish their repeal efforts , the Texas firebrand is n't on the same page about everything . 
Cruz wants to go as big as possible , and if Senate rules prohibit his idea , he believes Vice President Mike Pence should simply overrule the parliamentarian . 
"The parliamentarian merely advises , the vice president decides ," Cruz said . 
But on almost every other front , Republicans say , Cruz is being highly productive .

Q: More than 30 000 brain scientists are in Washington  D.C.  this week attending the Society for Neuroscience meeting. One of the hot topics this year is mental disorders such as depression and schizophrenia and autism.  NPR science correspondent Jon Hamilton  has just come from the meeting to talk about some of what  he 's been seeing and hearing. Hi  John. Thanks for coming.
 JON HAMILTON   BYLINE: Hi.
 HAMILTON : Twenty years ago  I'd say it didn't contribute much  but things are really changing. And I was really surprised. I was going through the abstracts to this year's meeting  and there were nearly a thousand papers that mentioned depression. There were 500 that mentioned schizophrenia or autism. And just this morning  there was this study on how - looking at the brain tissue of people with obsessive compulsive disorder and how it's different.
MARTIN: That's NPR's science correspondent Jon Hamilton. Jon  thanks so much.

Q: Thatâs not too far of a fling  actually. One really bad move could do it  but  Trump  has insulated  himself  with people far more competent and worthy of  their  positions. To date   they âre keeping  him  from stepping over the edge.
I never thought he could do the job. Heâs made some solid moves in his first year in office  but I actually give the credit to those around him. As I said from the beginning  it was the Cabinet that would do the actual work  and much like his business dealings   Trump  would be the Ronald McDonald of politics.  He âs the face of the presidency  but the actual work is being done by somebody else.
Wolff leans to some old rumors in the book about Trumpâs campaign plans. Namely   he  never intended to be president.  He  was going to clean up by being the almost president  build up a ready-made audience  and launch a new TV network venture  TrumpTV.
Because nobody thought  he  would win  nobody prepared for the job. In fact  while  Trump  bragged openly to  his  glassy-eyed followers that  he âd finance  his  own campaign and be beholden to none (How many times did I hear a Trumper say  â He  canât be bought!â)   he  put very little of  his  own money into the campaign.  He  took donations  like every other candidate  but to this day  not a single  Trump  supporter can be convinced of that.
 He  didnât run  his  campaign like somebody that wanted to win. It was a show to  him .  He  was worthless in debates  because  he  obviously didnât understand the questions being asked of  him   but  his  base would flood online polls and declare  him  the winner  even before the debates were over (which tells me they didnât understand the questions  either  nor did they care).
 Trump  struck out at Wolff on Friday night (on Twitter  of course)  slamming  him  as a âloserâ and calling  his  book âboring and untruthful.â
Ok. Wolff  however  is thanking  Trump  for helping  him  sell books  which  in turn  is opening eyes.
