[Q]: Image copyright Supplied Image caption  Hayley Smith  lost  her  job when  she  told  her  employer about  her  depression
Hayley Smith was diagnosed with chronic depression in  her  early twenties: "I'd been bottling up quite a bit through most of my teens. Then it hit me a like a brick wall "  she  said.
 She  was so depressed  she  didn't leave the house for six months.
Things began to improve and when  she  was 23 years-old  she  got a job at a food and drink company. But  she  had weekly counselling to attend.
"Every Thursday I'd have to take the afternoon off. So I spoke to my boss. In the meeting  she  was fine with it and said 'do what you need to do' ".
But after the meeting  she  received an email being told  she  was going to be taken off  her  accounts and that  she  should think about seeking employment at a mental health charity as "they might relate".
The manager also told people in the office: "It went round. It was horrible - I felt really exposed "  she  said.
Working there for a few further months triggered  Hayley  to experience anxiety  depression and "massive trust issues".
Eventually  she  left.  She  started  her  own company in London which  she  still runs five years on: "In the long-term it's given me awareness of mental health - and the awareness to make sure I was never going to make people feel the way I was made to feel."

[Q]: Sam Querrey gave the United States a winning start in its bid to reach Saturday's final at the World Team Cup.
 Querrey beat Jan Hajek 6-3  7-5 on Thursday to put the U.S. 1-0 up against the Czech Republic in the Red Group and remain unbeaten in his three singles this week.
 "So far so good " said Querrey. "I thought today was the best I played out of the three matches. So I'm pretty excited."
 Hajek claimed the first break  when Querrey ended a long rally with a forehand error  to go 3-1 up but the American player responded by winning the next five games in a row to take the opening set.
 Both players saved a break point late in the second set before Querrey broke at 6-5  converting his third match point.
 "I've been working this week to try and hit my forehand a little bigger. I felt I did that today " said Querrey. "I felt pretty much anytime I got a forehand  I was able to take control of the point."
 Querrey said his win takes the pressure off the U.S. ahead of Friday's matches.
 "A little bit  yes. I think John (Isner) can go out there and play a little more freely  which is a good thing " Querrey said. "When we have the lead  you can swing away a little bit more than if we were 1-0 down.
 "Then  the Bryan brothers  we expect them to win every match. Hopefully  they are going to do that again."

[Q]: In announcing the changes   EPA Administrator Scott Pruitt  suggested many previously appointed to the panels were potentially biased because they had received federal research grants. The 22 boards advise EPA on a wide range of issues  including drinking water standards and pesticide safety.
"Whatever science comes out of EPA shouldn't be political science " said  Pruitt   a Republican lawyer who previously served as the attorney general of Oklahoma. "From this day forward  EPA advisory committee members will be financially independent from the agency."
 Pruitt  has expressed skepticism about the consensus of climate scientists that man-made carbon emissions are the primary cause of global warming.  He  also overruled experts that had recommended pulling a top-selling pesticide from the market after peer-reviewed studies showed it damaged children's brains.
 Pruitt  said  he  will name new leadership and members to three key EPA advisory boards soon â the Science Advisory Board  Clean Air Scientific Advisory Committee  and the Board of Scientific Counselors.
As part of his directive   Pruitt  said  he  will bar appointees who currently are in receipt of EPA grants or who are in a position to benefit such grants.  He  exempted people who work at state  local or tribal agencies  saying  he  wants to introduce more "geographic diversity" to the panels.
The five-page policy  Pruitt  issued Tuesday makes no mention of other potential conflicts of interest  such as accepting research funding from corporate interests regulated by EPA.
Tuesday's announcement comes after  Pruitt  in May said  he  would not reappoint nine of the 18 members of the Board of Scientific Counselors to serve a second three-year term  as had been customary.
"It obviously stacks the deck against scientists who do not represent corporate special interests " said Swackhamer  a retired professor who taught environmental health sciences at the University of Minnesota. "It speaks volumes that people funded by special interests are OK to be advisers  but not those who have received federal grants. "
Senate Environment Committee Chairman John Barrasso  a Wyoming Republican who shares Pruitt's skepticism of mainstream climate science   cheered the move.  He  said EPA's science boards would now better reflect the views of rural states like  his  own.
But environmentalists worried that  Pruitt  will now select board members with financial ties to the fossil fuel and chemical industries.
"The Trump EPA's continued attack on science will likely be one of the most lasting and damaging legacies of this administration " said Sen. Tom Udall of New Mexico  the ranking Democrat on the appropriations subcommittee that approves EPA's funding. " Pruitt  is purging expert scientists from  his  science boards â and replacing them with mouthpieces for big polluters."
