[EX Q]: Princess Kate  pregnant with  her  third child  made  her  first public appearance in six weeks to join Prince William and Prince Harry at Buckingham Palace to mark World Mental Health Day.
 Kate   35  showed a slight baby bump beneath the tea-length Temperley dress  she  wore to the event  thanking supporters for helping to change public perceptions about mental health.
Kensington Palace announced  Kate 's pregnancy on Sept. 4 when she was forced to cancel a planned engagement as a result of hyperemesis gravidarum.  Kate  also missed the first day of school for  her  son  Prince George  a few days later.
 Kate  has suffered from hyperemesis gravidarum  or acute morning sickness  with each of  her  pregnancies. The palace announced that with this pregnancy   Kate  is being cared for at Kensington Palace.
The last time  Kate  was seen in public prior to today was in late August when  she  joined William and Harry in viewing the Diana Memorial Garden at Kensington Palace on the eve of the 20th anniversary of Princess Diana's death.
"The Duchess' condition is improving but she is still suffering from hyperemesis gravidarum " an aide to Princess Kate said today. "The Duchess is delighted to be here tonight."
William  Kate and Harry founded Heads Together in 2016 to change the conversation on mental health.
William told guests that it was Kate who first pointed out the royal trio's shared interest in mental health advocacy. They have each been engaged with their individual charitable work on the issue: Harry with the armed forces; William with young men  suicide and homelessness; and Kate on addiction and childhood mental health issues.
 William  Kate  and Harry  announced Sunday  they  have invested 2 million pounds of  their  Royal Foundation funds in the second phase of  their  Heads Together campaign  which is designed to create online tools to help people with mental health issues.

[EX Q]: Joseph Lynn Pickett of Edwardsville  was also ordered to spend six months behind bars for the June threats  though  he 's already served the time since  his  arrest last year.
 Pickett  pleaded guilty in an agreement with prosecutors in October  after authorities said  he  posted several times online that  he  wanted to assassinate Trump.
The posts included frequent profanity and detailed death threats.  Pickett  also taunted federal authorities when  he  wasn't immediately arrested.
 His  co-workers reported the threatening posts to the Secret Service.  He  was later arrested.
Under terms of  his  sentencing last week   Pickett  also will be on supervised release for three years.

[EX Q]: To find out  Morning Edition asked two online daters who also spend their days thinking about online dating:  Megan Murray  a senior content strategist for Zoosk  an online dating site and mobile app  and Skyler Wang  a Ph.D. candidate in sociology at the University of California Berkeley .  Wang  also taught an undergraduate course at the University of British Columbia called What Makes Us Click  about online dating and  he  gave NPR permission to use  his  course title for Morning Edition's series on online dating.
 Wang  who identifies as gay   says before  he  and  his  friends go out to a bar   his  friends go on dating apps Tinder and Grindr to meet people at the bars where they're headed. "Now  the 'gayborhood' is in your cell phone "  he  says. "I think technology has created a better  more democratic social environment for especially marginalized groups."
"Basically  people use lists nowadays to get a better sense who they're attracted to and put a very quantitative twist to something that didn't used to be like that "  Wang  says.
 Wang  cautions that this kind of approach to dating lets users act like they are shopping  which isn't necessarily a good thing.  He  calls the practice "relationshopping " and  he  warns that it not only objectifies others  it de-emphasizes the importance of building a relationship. People sometimes treat dating as if they are looking for the perfect dress or handbag   Wang  says.
"Relationshopping is problematic because people give up so quickly now "  Wang  says  "and for the most bizarre reasons."  He  says that people may choose to not go on a second date with someone simply because they don't like their hair.
"It makes you feel like people are a commodity "  he  says.
In fact   Wang  says  some sites describe themselves as more of an introduction service than a dating site.
"The dating doesn't happen online. The dating happens in person "  Wang  says. "So in a way they're trying to preserve that magic."
