Twitter rolled out a 280 character limit for most of its users Tuesday, and, predictably, lots of people are unhappy.That doubles the original 140 character limit that Twitter has maintained since it launched in 2006.Twitter began testing longer tweets in late September, and found that once the novelty of tweeting longer wore off, most people in the test group didn't use all of the available characters. According to the company, only 5% of tweets sent by people in the 280-character test group were longer than 140 characters, and just 2% were over 190 characters.Many users complained about the initial tests. Now that just about everyone's got 280 characters to work with, more people say they're frustrated or confused by the decision. Others are using new characters to make jokes. Other people were curious about how the new parameters will change the way people interact on the platform.The big question on everyone's mind is how President Donald Trump, an avid Twitter user, will use the expanded space. The president tweeted two messages Tuesday that went beyond the old 140 character limit.But another Trump doesn't appear to like the change. Donald Trump, Jr. tweeted a critique of the expanded character limit -- although he used 195 characters to do so.  1286

Vaping by U.S. teenagers fell dramatically this year, especially among middle schoolers, according to a federal report released Wednesday.Experts think last year’s outbreak of vaping related illnesses and deaths may have scared off some kids, but they believe other factors contributed to the drop, including higher age limits and flavor bans.In a national survey, just under 20% of high school students and 5% of middle school students said they were recent users of electronic cigarettes and other vaping products. That marks a big decline from a similar survey last year that found about 28% of high school students and 11% of middle school students recently vaped.The survey suggests that the number of school kids who vape fell by 1.8 million in a year, from 5.4 million to 3.6 million, officials said.But even as teen use declined, the report shows a big bump in use of disposable e-cigarettes. The Food and Drug Administration earlier this year barred flavors from small vaping devices like Juul and others that are mainly used by minors. The policy did not apply to disposable e-cigarettes, which can still contain sweet, candylike flavors.“As long as any flavored e-cigarettes are left on the market, kids will get their hands on them and we will not solve this crisis,” Matt Myers of the Campaign for Tobacco Free Kids said in a statement.The national survey is conducted at schools each year by the Centers for Disease Control and Prevention and usually involves about 20,000 middle and high school students. It asks students if they had used any vaping or traditional tobacco products in the previous month. The survey was cut short this year as schools closed because of the coronavirus pandemic.Federal health officials believe measures like public health media campaigns, price increase and sales restrictions deserve credit for the vaping decline. The age limit for sales in now 21.But they also acknowledge the outbreak probably played a part. The CDC’s Brian King said sales started falling in August — when national media coverage of the outbreak intensified.“It’s possible that some of the heightened awareness could have influenced decline in use,” said King.By the time the outbreak was winding down early this year, more than 2,800 illnesses and 68 deaths had been reported. Most of those who got sick said they vaped solutions containing THC, the ingredient that produces a high in marijuana. CDC officials gradually focused their investigation on black market THC cartridges, and on a chemical compound called vitamin E acetate that had been added to illicit THC vaping liquids.Kenneth Warner, a professor emeritus at the University of Michigan’s school of public health, said the teen vaping drop was larger than expected.“This does look like a very substantial decrease in a single year and it’s very encouraging,” said Warner, a tobacco control expert.Among the likely factors, Warner noted the general negative publicity surrounding vaping. Additionally, Juul preemptively pulled all its vaping flavors except menthol and tobacco last fall ahead of federal action.Warner and other researchers have tracked a recent decline in teen smoking to all-time lows — about 6% — even as vaping has increased. He said it will be critical to watch whether teen smoking begins rising again as fewer teens vape.The new figures were disclosed on the same day that all U.S. vaping manufacturers faced a long-delayed deadline to submit their products for FDA review. Generally, that means the vaping companies must show that their products help smokers reduce or quit their use of cigarettes and other tobacco products.E-cigarettes first appeared in the U.S. more than a decade ago and have grown in popularity with minimal federal regulation.___Perrone contributed from Washington.___The Associated Press Health & Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

More than 50 volunteers signed up to help assemble.

We have to honor our veterans that have gone before us," said club member Tyler Nelson."It was overwhelming. The whole neighborhood turned out, cheering. They had posters. Best Christmas present someone could receive," said Brinemann.At the cemetery, Brinemann and seven others quietly placed the wreath sprays at 311 grave markers."The cemetery just looks like how it should be now," said Brinemann. 1686

  

TULSA, Okla. — A Tulsa police major is suing several media companies for publishing comments he made in a radio interview in June.Major Travis Yates has filed a lawsuit against Comcast, Gannett, Public Radio Tulsa, Gatehouse Media and others, saying their reports portrayed him in a "false light."During a June appearance on Talk Radio 1170 with host Pat Campbell, Yates said data shows systemic racism "doesn't exist" and "all the research says we're shooting African Americans about 24% less than we ought to be based on the crimes being committed."In the days following his comments, the Tulsa Police Department opened an investigation into Yates, and Tulsa Mayor G.T.
