Top North Korean officials warned the United States in a letter that denuclearization talks are "again at stake and may fall apart," sources familiar with the process told CNN.The letter was delivered to US Secretary of State Mike Pompeo, who abruptly canceled his fourth trip to Pyongyang, hours before he was scheduled to depart with his new special envoy Stephen Biegun on Friday, sources said.Three sources with direct knowledge of the North Korean position on denuclearization said the letter stated that Kim's regime felt that the process couldn't move forward because "the US is still not ready to meet (North Korean) expectations in terms of taking a step forward to sign a peace treaty."The US has so far been unwilling to replace the armistice agreement that ended the Korean War with a permanent, legally binding peace treaty, which would require the approval of two-thirds of the US Senate.If a compromise cannot be reached and nascent talks crumble, Pyongyang could resume "nuclear and missile activities," the sources said.The existence of the letter, sent to Pompeo by Kim Yong Chol, the former head of North Korea's spy agency, was first reported by the Washington Post.The Post, which characterized the letter as a "secret" communication, said it wasn't clear how Kim had gotten the letter to Pompeo, but suggested that it may have been sent through its UN mission.However, Pompeo has been relying on other backchannels, as opposed to dealing directly with his diplomatic counterpart North Korean Foreign Minister Ri Yong Ho, one source said."Before and after Pompeo became the Secretary of State, he seemed to be more interested in maintaining and engaging with Kim Yong Chol through a backdoor channel, rather than with his formal counterpart Ri Yong Ho," said the source. 1809

'Tis the season for spicy lattes, fast food turkey sandwiches and pumpkin-flavored everything.If you're a fan, you'd better act fast: They won't be around for long.That's by design. Seasonal items are an important marketing tool for the food industry, according to Alexander Chernev, a professor of marketing at Northwestern University's Kellogg School of Management.Limited releases almost give consumers a Pavlovian response. For example, when the weather turns colder, Starbucks customers habitually get excited about Pumpkin Spice Lattes. In November, customers come in to check out the new holiday cups."When you have these exclusive products, which exist for a short period of time, it gives people a reason to come to the store," Chernev explained.It's not just Starbucks that comes out with seasonal specials: Dunkin' Donuts announced a whole slew of pumpkin-flavored treats in August. McDonald's is getting ready for winter with the McRib. As the holiday season gets into full swing, we'll be sure to see Santa on Coca Cola bottles, turkey sandwiches from Subway and more. In the spring, it'll be Girl Scout cookie time.Related: The McRib is back at McDonald's For fast food chains in particular, which rely on familiarity, holiday items can offer consumers some variety."You need consistency because that's the brand mantra," said Chernev. "But no matter how much you like something, consuming something different ... increases the enjoyment of what you consumed before."Chernev says it's a neat marketing ploy: Although a specialty item may be exciting on its own, it can also remind consumers how much they like the basics.Seasonal offerings can also give brands a chance to test a new product. When Starbucks announced the return of the Pumpkin Spice Latte this year, it also unveiled the Teavana Pumpkin Spice Chai Tea Latte.And Chernev pointed out that seasonal menu items mean brands have something new to talk about every quarter.Starbucks says that's part of the rationale behind its seasonal drinks"We strive to provide our customers with unique, seasonal offerings to celebrate each season, and customer response has been extremely positive to that," a company spokesman said.Related: Hey, latte fans: Maple is having a moment this fallThere are some basic supply-and-demand economics behind limited-time releases too: Scarcity can build hype."It's a way to create excitement for the menu," said R.J. Hottovy, a consumer strategist for Morningstar.Items that might be popular for a few months probably wouldn't generate enough year-round demand.For example, when the McRib debuted in 1981, it was a dud. McDonald's pulled it from its menu four years later. Though it never achieved nationwide success, there were parts of the country where the McRib generated a solid enough fan base to bring it back every now and then."There's a lot of mystery around why the McRib comes and goes, but to be honest it's a local option based on consumer demand," a McDonald's spokesman said.The McRib works very well in the Midwest, but doesn't necessarily work as well in the coastal areas, Hottovy noted. That's why it makes sense to restrict the amount of McRibs that go on sale.Hottovy explained that sales typically rise for a short time when companies unveil seasonal items. But after a few weeks, that demand drops off after the core fans of the limited time product are satisfied.So enjoy your Pumpkin Spice Latte while it lasts. And let's be honest, you probably wouldn't want one in April.The-CNN-Wire 3526

Three freshmen on the UCLA men's basketball team accused of shoplifting in the Chinese city of Hangzhou could be months away from returning home while the legal process in their case plays out.ESPN, citing a source with firsthand knowledge, reported Wednesday that LiAngelo Ball, Cody Riley and Jalen Hill were released on bail after being questioned about stealing sunglasses from a Louis Vuitton store near the team hotel. ESPN's LA-based reporter Arash Markazi is covering the team from China.Chinese officials wouldn't confirm the ESPN report that Ball, Riley and Hill were arrested. Hua Chunying, a spokeswoman for China's Foreign Ministry, said the case had been reported to US authorities. "China is handling this case in accordance with the law, and will guarantee the rights in accordance with the law, for those involved in this case," she said.Ball's father, LaVar, who is in China, said in a statement on social media that the process "could take ... months.""Ball, Riley and Hill are being required by Hangzhou police to remain at their hotel until the legal process is over, which could take days, weeks or even months," he said. "The hope is obviously sooner rather than later."If convicted of grand larceny, the players could face a prison sentence of between three and 10 years, according to Chinese criminal law.UCLA is in China for a week-long visit and is scheduled to open its season in Shanghai on Saturday against Georgia Tech. When asked about the arrests at a news conference, UCLA Coach Steve Alford said the players in question would not play in Saturday's game.LiAngelo Ball is a younger brother of former UCLA star Lonzo Ball, now a rookie with the Los Angeles Lakers.In a statement on Weibo earlier Wednesday, LaVar Ball called the incident "unfortunate to both the Ball family and UCLA."Cooperation and consternationUCLA, one of the United States' premier college basketball programs, says the university is cooperating fully with local authorities."We are aware of the matter involving UCLA student-athletes in Hangzhou, China and we are gathering more information," UCLA Associate Director of Athletic Communications Alex Timiraos said in a statement.Larry Scott, commissioner of the Pacific 12 Conference, of which UCLA is a member, said in a statement that the student-athletes "were involved in a situation" and were cooperating with local authorities."We are very disappointed by any situation that detracts from the positive student-athlete educational and cultural experience that this week is about," the statement said. "Whether in the United States or abroad, we expect our student-athletes to uphold the highest standards."News of the incident broke as US President Donald Trump landed in China, part of a trip to five Asian nations.A spokesperson from the US State Department told CNN it is "aware of reports of three US citizens arrested in China. We stand ready to provide appropriate consular assistance for US citizens."Due to privacy considerations, the State Department declined to comment further.The UCLA team was in Hangzhou to visit the headquarters of Alibaba, the e-commerce giant which is sponsoring Friday's game.The Ball familyLiAngelo Ball, a freshman, is the middle child of LaVar and Tina Ball. Their youngest son, LaMelo Ball, is in high school.The outspoken LaVar Ball has made regular headlines with his provocative comments since eldest son Lonzo began starring at UCLA last year. A former college basketball player who has been training his sons since they were kids, LaVar Ball said he could beat Michael Jordan one-on-one and that Lonzo, while still in college, was better than two-time NBA MVP Steph Curry.Lavar also predicted all his sons will eventually play for the Lakers.He is already a third of the way there. Lonzo Ball was selected second overall by the Lakers in the 2017 NBA draft and is seen as a building block for the team's future.The family stars in its own reality show on Facebook, "Ball in the Family," and boasts an athletic apparel line, Big Baller Brand. Its first sneaker, the ZO2, raised eyebrows when it was priced at 5.LaVar, Tina and LaMelo Ball went to China to watch LiAngelo play his first game as a Bruin and promote the opening of a Big Baller Brand pop-up shop in Shanghai.  4295

This is supposed to be the first week of class for many Washington state schools. But exactly when students in some districts will go to class remains a mystery.Teacher strikes in two districts have already forced the cancellation of classes on their first day of school Tuesday.Evergreen Public Schools are closed because no deal has been reached between the school district and the Evergreen Education Association over salaries.Negotiations are ongoing, and the school district said it will give parents at least 24 hours' notice before classes will begin.The Washougal School District also missed its first day of school Tuesday due to a strike by the Washougal Association of Educators.School district representatives met with union members and mediators Monday to try to reach an agreement on teacher salary increases."The district and the association have worked hard to reach an understanding but, unfortunately, we were not able to come to an agreement," district Superintendent Mary Templeton said.Four other state school districts, which are scheduled to start classes Wednesday, could have those plans derailed by strikes over salaries and benefits.Vancouver Public Schools, Longview Public Schools, Battle Ground Public Schools and the Hockinson School District all announced that negotiations are continuing with teachers and mediators.The Hockinson School District said it's hoping to start classes on time but is asking parents to have backup plans for their children, just in case. 1515

To end the pandemic, there need to be enough people immune to COVID-19 and there are two ways to do that: immunity through infection or from a vaccine."I think racing to herd immunity is the dangerous thing that I’m concerned about," said Dr. Stuart Ray, a professor of medicine at Johns Hopkins University School of Medicine.Herd immunity is when the spread of the infection cannot be sustained because the number of people who are immune is high enough. Some countries are considering it as a strategy to combat COVID-19.But Ray said it could not work in the US unless much more effective treatments are developed.He says on average, a newly infected person infects two others, so to have herd immunity from COVID-19 about 60 percent of people would have to become immune."We would have something like another 100 million people, maybe more, infected. 150 million more and even if the major complication rate is a fraction of 1 percent, we will still have huge numbers of deaths," said Ray.He said we also don’t know if just having had the infection once will create lasting immunity to control the spread."It possible that you could be immune enough not to get sick and still not immune enough to prevent that spread and so herd immunity is a tough bar for us to aim for because not only do we need 60 percent of people to be immune but we need them to be immune in a way that prevents them from infecting other people," said Ray.The other way to achieve herd immunity would be through a vaccine."Vaccines can work better, provide better immunity than the natural infection does. The new shingles vaccine provides great immunity and protects more than 95 percent of people from getting shingles," said Ray.Several vaccines are still going through the last phase of clinical trials to see if any also creates enough immunity to prevent passing the virus along.This story was first reported by Abby Isaacs at WMAR in Baltimore, Maryland. 1946
