After one of its cars made a high-speed run on a German test track, Bugatti says it is the first production auto manufacturer to make a car that exceeded 300 miles per hour.A specially modified Bugatti Chiron, driven by Bugatti test driver Andy Wallace, went 304.8 miles per hour on a 5.5 mile straightaway on Volkswagen's Ehra-Lessien test track in Germany, the company said. Bugatti is owned by the Volkswagen Group, which also owns Lamborghini and Bentley.Bugatti is a "production auto manufacturer," meaning it makes multiple copies of the same car for use on public roads albeit, in Bugatti's case, in low numbers and at very high prices. But this was not the ordinary sort of Chiron one can buy for million from the Bugatti factory in Molsheim, France. This record was set by a prototype Chiron that Bugatti developed in cooperation with the Italian race car manufacturer Dallara. (Cars built solely to compete for speed records have gone as fast as over 500 miles per hour.)In addition to making safety alterations for such high speeds, the companies modified the car's body to improve aerodynamics. The tires were also specially developed by Michelin, which makes the tires for regular Chiron cars as well. The tires are still legal for road use but they were reinforced to withstand these extremely high speeds."It's inconceivable that a car would be capable of this. But the Chiron was well 1416
A senior U.S. official says the United States and the Taliban have reached a truce agreement that will take effect “very soon” and could lead to withdrawals of American troops from Afghanistan. The official said Friday the agreement for a seven-day “reduction in violence” to be followed by the start of all-Afghan peace talks within 10 days is “very specific” and covers the entire country including Afghan forces. The official spoke on condition of anonymity because the official wasn't authorized to discuss details ahead of an official announcement. The developments come as U.S. Secretary of State Mike Pompeo and Defense Secretary Mark Esper met Friday in Munich with Afghanistan's President Ashraf Ghani. 723

About 1 out of 5 high school students in the U.S. say they vaped marijuana in the past year, and its popularity has been booming faster than nicotine vaping, according to a report released Wednesday.“The speed at which kids are taking up this behavior is very worrisome,” said Dr. Nora Volkow of the National Institute on Drug Abuse, the federal agency that pays for the large annual teen survey.Electronic cigarettes and other battery-powered vaping devices mostly heat a liquid containing nicotine into a vapor that’s inhaled, In recent years, they have been increasingly used to vaporize THC, the chemical that gives pot its high.The University of Michigan survey asks students in grades 8, 10 and 12 across the country about smoking, drinking and drugs. About two-thirds of this year’s 42,000 participants were asked about vaping marijuana.Vaping nicotine is still more popular: about 1 in 4 high schoolers said they had done it at least once in the previous year. But vaping marijuana grew more quickly: 1 in 5 high schoolers had done it at least once the year before.About 1 in 7 high school seniors this year were considered current users of marijuana vaping — they had vaped in the month before they took the survey. That’s almost doubled from 1 in 13 the year before.Overall, marijuana use — in all its forms — is holding steady. It’s not clear if students are switching to vaping or continuing to use other forms as well, said Richard Miech, who oversees the survey.Daily marijuana use rose in both middle school and high school kids in 2019, and “if you want to be a daily marijuana user, vaping makes it easier,” he said.It’s odorless and slips easily into a pocket. “You can just kind of graze on that all day,” he said.The survey is in the Journal of the American Medical Association, which also published results of a different survey in 2018 that showed an increase in marijuana vaping among middle and high school students.Both have limitations: the surveys rely on what kids say, and it does not include teens who are not in school. Federal and state laws ban minors from using marijuana recreationally, and prohibits sale of vaping products to kidsThe Michigan survey was conducted earlier this year, before reports of a surge in cases of vaping-related lung damage, mostly in teens and young adults who used black-market THC products.Volkow said the illnesses “may scare some teenagers away” from vaping marijuana.The survey also found most other forms of teen drug use are flat or declining, including alcohol, ecstasy, heroin, cocaine, and meth. An exception was LSD, which has been increasing in 10th and 12th graders. About 3.6% of high school seniors said they’d dropped acid in the previous year.___The Associated Press Health and Science Department receives 2797
