 The backlash against electric scooters shows some sign of waning as cities that cracked down on the startups begin thinking maybe they aren't so bad after all.Cities across the country moved aggressively to rein in, and even shut down, companies like Bird and Lime when hundreds of scooters filled their streets and cluttered their sidewalks seemingly overnight earlier this year. Many impounded the scooters. Some levied fines.Yet some cities are softening their stance as they realize scooters can play an integral role in easing congestion, reducing pollution, and bolstering public transit. And the startups, having watched companies such as Uber be penalized for antagonizing municipal governments, are willing to play nicely if it means expanding their market.Austin, Texas, offers a case in point. The city found itself inundated with Bird's sleek black scooters in April. Lime flooded the city with its bright green scooters a short time later."The human response would be, shake off the gloves and let's go. Let's fight this. You just disrupted my city," Jason JonMichael, assistant director of Austin's smart mobility program, told CNNMoney.Instead, city officials talked things over. As it happened, they'd been planning a dockless bikesharing program. Their plan called for eventually adding scooters to the mix, so they decided to work with the companies to make it happen, JonMichael said.Rather than issue a cease and desist letter -- an approach some cities took -- Austin warned the companies that it would confiscate scooters blocking sidewalks. And city officials set to work crafting an ordinance governing a permitting process for scooter services, including speed restrictions and fees for operating.Today you'll find 2,000 scooters all over Austin. People love them so much -- each scooter is ridden nearly 20 times daily -- that their batteries often go dead by noon, JonMichael said. And it's making life better in the city, too. JonMichael said people are taking fewer solo trips in cars, which means less congestion and pollution.The city reviews each company's performance every six months, reserving the right to revoke the license of anyone who isn't playing by the rules. That's got the startups working hard to stay in the city's good graces by offering discounted rides to low-income residents and developing tools that allow people to report bad behavior by anyone zipping along on a scooter.City officials now see scooter and bikeshare firms as allies in their efforts to improve quality of life and expand transit options. The startups are "bringing to the table discussions about developing a roadmap to deploy transportation that from the get-go has equity and access for all built into it," JonMicheal said.Bird hopes to broker a similar alliance in its hometown of Santa Monica, California. The company launched in September 2017 and followed the ridesharing playbook that says it's better to seek forgiveness than permission. Bird launched without proper business licenses, and in February agreed to pay the city 0,000 in fines to settle a criminal complaint.Despite the trouble, Santa Monica officials wanted electric scooters to stay given their focus on multi-modal transportation and carbon-light living. The city gave Bird and Lime conditional permits while it worked to set up a 16-month pilot program. Earlier this month, the Santa Monica government ranked applicants to its scooter program, and Bird placed 10th."That was a real wake-up call. This is a fantastic business, and there's a lot of competitors who want to do it," Dave Estrada, the Chief Legal Officer at Bird told CNNMoney. "It really helped us take a good look at how we were doing operations and how we can best serve cities."That explains why Bird on Wednesday announced several concessions intended to curry favor with Santa Monica and other cities. It will let cities designate no-go areas where people can't ride or park scooters. It will grant cities the option to convey the rules of the road and other safety tips in messages users see before riding off. And it will share data that will help cities understand how people are using its scooters.Bird went so far as to resubmit its Santa Monica application earlier this month, to be more appealing to the government. At the city's request, it has begun limiting the speed of its scooters to 5 mph on the beach path, and in Palisades Park, two areas that have been controversial. It also plans to send text alerts to riders who stray into areas where cities don't want scooters.A lingering challenge for the industry is sidewalk riding, which irritates many pedestrians. The scooter companies instruct customers to ride in bike lanes, but bike lanes are rare and sometimes customers still choose sidewalks. Bird is exploring ways to discourage sidewalk riding, by automatically detecting with sensors when a scooter is on a sidewalk.It may not be popular with every rider, but the startup has realized that cities are its customers too."We started understanding that we had one customer, the rider," Estrada said. "Now we really understand a lot better that customers include cities and people who don't ride Birds." 5222

(CNN) -- For six months now, the days have grown shorter and the nights have grown longer in the Northern Hemisphere -- but that's about to reverse itself.Winter solstice, the shortest day of 2019, will be Saturday, December 21. Or it will be Sunday, December 22. Which day is it for you? It all depends on your time zone.CNN meteorologists Dave Hennen, Judson Jones and Brandon Miller help us understand the science and timing behind the solstice. And then we'll discover some traditions and celebrations around the world that could inspire a travel adventure.The science and timing behind a winter solsticeThe winter solstice marks the shortest day of the year in the Northern Hemisphere, when the sun appears at its most southerly position, directly overhead at the faraway Tropic of Capricorn.It's the reverse in the Southern Hemisphere. There, it marks the longest day of the year -- and the beginning of summer in places such as Argentina, Namibia and New Zealand.When exactly does it occur?The solstice usually takes place on December 21. The time that the solstice occurs and the day itself shifts because the solar year (the time it takes for the sun to reappear in the same spot as seen from Earth) doesn't exactly match up to our calendar year.If you want to be super-precise in your observations, the exact time of the 2019 winter solstice will be 4:19 Universal Time on Sunday. Here are some examples of when that will be for local times around the world:-- Tokyo: 1:19 p.m. Sunday-- Dubai: 8:19 a.m. Sunday-- Rome: 5:19 a.m. Sunday-- Dakar, Senegal: 4:19 a.m. (same as Universal Time)-- Philadelphia: 11:19 p.m. Saturday-- Seattle: 8:19 p.m. Saturday-- Honolulu: 6:15 p.m. SaturdayIf you don't live in one of these time zones above, the website EarthSky has a handy conversion table for your time zone. You might also try the conversion tools at Timezoneconverter.com or WorldTimeServer.com.What causes the winter solstice to even happen?Because the Earth is tilted on its rotational axis, we experience seasons here on Earth. As the Earth moves around the sun, each hemisphere experiences winter when it's tilted away from the sun and summer when it's tilted toward the sun.Wait. Why is the Earth tilted?Scientists are not entirely sure how this occurred, but they think that billions of years ago, as the solar system was taking shape, the Earth was subject to violent collisions that caused the axis to tilt.What other seasonal transitions do we mark?The equinoxes, both spring and fall, occur when the sun's rays are directly over the equator. On those two days, everyone has an equal length of day and night. The summer solstice is when the sun's rays are farthest north over the Tropic of Cancer, giving us our longest day and summer in the Northern Hemisphere.Winter solstice traditions and celebrationsIt's no surprise many cultures and religions celebrate a holiday -- whether it be Christmas, Hanukkah, Kwanzaa or pagan festivals -- that coincides with the return of longer days.Ancient peoples whose survival depended on a precise knowledge of seasonal cycles marked this first day of winter with elaborate ceremonies and celebrations. Spiritually, these celebrations symbolize the opportunity for renewal, a shedding of bad habits and negative feelings and an embracing of hope amid darkness as the days once again begin to grow longer.Many of the ancient symbols and ceremonies of the winter solstice live on today.Here are five extraordinary destinations where you can experience something magical during winter's relentlessly long night:UNITED KINGDOM: Cornwall and StonehengeBetter known for pirates than the solstice, the town of Penzance on the southwest coast of England has revived a delightful array of Cornish solstice events leading up to winter solstice. The Montol Festival is a fun mix of pagan customs and more recent Christmas traditions that were once common throughout Cornwall.Early in the week, join in caroling and other events. On the solstice, referred to here as Montol Eve, get your dancing card ready for the Guise, a community dance in which people dress in masks and other "topsy-turvy" disguises based on a 19th-century tradition of the rich dressing in rags while poorer citizens effected a "mock posh" look.You can also don your finery for torchlit processions. The merrymaking only continues when the revelers disperse to pubs around town.With some planning, it's also possible to incorporate a trip to Stonehenge, the UK's most famous site for solstice celebrations. On the winter solstice, visitors have the rare opportunity to enter the towering, mysterious stone circle for a sunrise ceremony run by local pagan and druid groups.The trip from Penzance to Stonehenge takes less than four hours by car, making it entirely feasible to spend the night in Salisbury, the nearest town to Stonehenge, and rise before dawn for the ceremony among the stones.SWEDEN: Santa Lucia, yule and aurora borealisSweden is rich with solstice traditions. Elements of the yule, Northern Europe's a

  

You likely aren't planning to visit Chernobyl any time soon, but that doesn't have to mean you can't get a taste of it. A team of scientists from the UK and Ukraine have created a vodka distilled from rye grown in the exclusion zone near the site of Chernobyl's nuclear power plant. It's also made from water pulled from the area's aquifer. So, would you be insane to drink what they are calling 'Atomik' vodka? The makers say no, and that it’s perfectly safe to drink. The scientists, however, admit the grain starts out radioactive but claim the distillation process removes the dangerous isotopes. They even say they had a university lab run tests to ensure the vodka was safe to drink.They are hoping to release the vodka to the public in limited supply, where it will have to compete with liquors that were never radioactive. The Chernobyl Spirit Company says it will donate 75 percent of its profits to people who still live in the area. 956

  

(AP) — Native American comic book fans hope a new Marvel anthology by Native artists and writers will jump-start authentic representation in mainstream superhero fare. “Marvel Voices: Indigenous Voices #1” is expected in November during Native American History Month and will revisit some of its Native characters. Marvel says the project was planned long before the nation’s reckoning over racial injustice, which has prompted changes like the Washington NFL team dropping its Redskins mascot. The lead artist for the comic book says the series is correcting a decades-old problem of Native American or Indigenous representation in the medium. 652
