The days of passengers bringing rabbits, turtles and birds on planes as emotional-support animals could be ending. The U.S. Department of Transportation on Wednesday proposed that only specially trained dogs qualify as service animals, which must be allowed in the cabin at no charge.Airlines could let passengers bring other animals on board, but hefty fees would apply. Airlines have complained that some passengers try to get their pets on board for free by claiming they need them for emotional support under the current rules. 543

The cost of Christmas trees is going up and it is because of millennials, according to the National Christmas Tree Association.

The first three nomination races have not gone well for former Vice President Joe Biden. The once frontrunner for the Democratic nomination has struggled to attract voters to the polls thus far. But Saturday’s primary in South Carolina could be what the doctor ordered for an ailing campaign. Or it could be what brings the campaign to a halt going into Super Tuesday. POLLS CLOSE AT 7 P.M. ET ON SATURDAY.South Carolina represents the most delegates (54) that have been up for grabs in a nominating race so far. It is also far more diverse than Iowa and New Hampshire. While Biden was hopeful a more diverse electorate would improve his fortunes in Nevada, he watched as Sen. Bernie Sanders won in convincing fashion last week. Still, Nevada was Biden’s best performance of the three races so far, but his second-place finish only showed how much ground he has lost to Sanders. DELEGATE COUNT THROUGH FEB. 28:SANDERS: 45BUTTIGIEG: 26BIDEN: 15WARREN: 8KLOBUCHAR: 71991 NEEDED TO WIN THE NOMINATIONPolling for Saturday’s primary indicates South Carolina could put Biden back into the mix as Democrats prepare for the most important night of the nomination on Tuesday. Monmouth University released a South Carolina primary poll on Thursday indicating Biden was leading the pack with 36%. The poll showed that Sanders and Tom Steyer were jockeying for second with 16% and 15% respectively. 15% is a key figure for the race as it is the threshold to receive delegates – anything less results in a goose egg. Helping Biden’s standing with the black vote was this week’s endorsement from Rep. Jim Clyburn. Clyburn, the third-most powerful Democrat in the House, has been one of South Carolina’s most recognizable Democrats for decades. “I know Joe Biden. I know his character, his heart, and his record. Joe Biden has stood for the hard-working people of South Carolina. We know Joe. But more importantly, he knows us,” Clyburn told voters this week. Following Saturday’s race is Super Tuesday when one-third of all delegates are up for grabs. The night could be intriguing for several reasons. One is the foray of Mike Bloomberg into the race. He sat out the first four nominating contests, and has spent a fortune of his own money to advertise in delegate-rich states such as Texas and California. Super Tuesday also could provide clarity on which candidate or candidates will take on Sanders deep into the nominating race. Finally, it could give an indication on whether Democrats need to prepare for a brokered convention. As Democrats allocate delegates proportionally, having a candidate such as Sanders come away with a majority of the delegates by July's convention could be a challenge. 2701

The Centers for Disease Control (CDC) says depression affects nearly 8% of people at any time. The numbers of those who get treatment are far lower. For some, they don’t recognize the symptoms or they don’t want to take medication. Wendy Moreno is among those who struggle with depression. After a traumatic experience four year ago, she decided she needed professional help. She went to therapy and got on medication, but she didn’t feel it was working.“I was just at a point where I wanted to try something new,” said Moreno. Her therapist told her about 569

The 2019 Nobel Prize for Medicine has been jointly awarded to William Kaelin Jr., Sir Peter Ratcliffe and Gregg Semenza for their pioneering research into how human cells respond to changing oxygen levels.Announcing the prize at the Karolinska Institute in Stockholm on Monday, the Nobel committee said that the trio's discoveries have paved the way for "promising new strategies to fight anaemia, cancer and many other diseases."The 2019 medicine laureates, the committee added, have identified molecular machinery that regulates the activity of genes in response to varying levels of oxygen.The importance of oxygen has long been established, the committee explained, but how cells adapt to changes in its levels remained unknown.Randall Johnson, prize committee member, described the trio's work as a "textbook discovery.""This is something basic biology students will be learning about when they study, at aged 12 or 13, or younger, biology and learn the fundamental ways cells work. This is a basic aspect of how a cell works and, from that standpoint alone, it's a very exciting thing."The winnersNew York-born Kaelin established his own research laboratory at the Dana-Farber Cancer Institute in Boston and became a full professor at Harvard Medical School in 2002.Semenza, also born in New York, became a full-time professor at Johns Hopkins University in 1999 and since 2003 has been the Director of the Vascular Research Program at the Johns Hopkins Institute for Cell Engineering.Ratcliffe, who was born in Lancashire, England, studied medicine at Cambridge University and established an independent research group at Oxford University, becoming a full professor in 1996. 1694
