DENVER, Colorado — Cloud seeding can provide between 5% and 15% more snow to help ski areas, farmers and watersheds in the state, supporters say. "These observations show us that cloud seeding does work," said University of Colorado researcher Katja Friedrich, who has studied cloud seeding inside and outside of a laboratory. She worked with scientists who flew planes near moisture-rich clouds and injected them with silver iodide, a substance that causes moisture to become heavy and fall to the ground as snow. On a radar image, she pointed outlines of snow that later formed. The visible lines matched the pattern the cloud seeding plane had flown in the sky. Cloud seeding in Colorado aims to produce more snow, not rain. Friedrich said it's difficult to quantify how much additional snow is created. Cloud seeding doesn't make more clouds, but supporters believe it gets more snow out of an approaching storm. Planes can be used to seed approaching storm clouds. Ground seeders use propane to heat the air and also used in the mountains and Western Slope. Silver iodide is then added to the warmed air as it rises. The moisture, already in the clouds, bonds to the silver iodide. When it becomes heavy, it falls to the ground as snow. Cloud seeding has been happening for about 70 years in Colorado but is slowed in years when there is heavy snowfall. Cloud seeders operated during the 2018-2019 winter but slowed in places where significant snowpack accumulated. A man who owns a cloud seeding company on the Western Slope said the technology works well. Cloud seeder's viewpoint Cloud seeders dot highpoints in Colorado from the west to central part of the state. Ski areas hire Eric Hjermstad's Western Weather Consultants company to cloud seed early in the season, so there's more natural snow before opening day. He continues seeding until mid-April. He showed off a cloud seeder located at a recreation site north of Leadville. He can remote start the seeder, turn on the propane flame and add the silver iodide. 2040

LACKLAND AFB, Texas – The Centers for Disease Control has now confirmed a 15th case of the new coronavirus, officially named COVID-19, in the United States. Thursday, the CDC said the new patient was among a group of people under federal quarantine at JBSA-Lackland in Texas who recently returned to the U.S. from China on a State Department-chartered flight that arrived on Feb. 7. This is the first person under quarantine at JBSA-Lackland who had symptoms and tested positive for COVID-19, according to the CDC. The new patient is currently isolated and receiving medical care at a designated hospital nearby. This isn't the first case of an evacuee being diagnosed with COVID-19. The 13th and 14th cases of the virus were found among evacuees who were flown last week from Wuhan to Marine Corps Air Station Miramar in Southern California. This newest COVID-19 case was the first confirmed in Texas. The other 14 cases have been confirmed in California, Illinois, Massachusetts, Washington state, Arizona and Wisconsin.Health officials say there will likely be additional COVID-19 cases in the coming days and weeks, including people who recently returned from Wuhan. While 195 people were discharged from quarantine on Tuesday, more than 600 people who returned on chartered flights from Wuhan remain under federal quarantine and are being closely monitored to contain the spread of the virus.In China, the government said Thursday that more than 59,800 people have been infected with the virus and the country’s death toll has risen to 1,367, 1564

At the Good Times Burgers & Frozen Custard in Denver, Colorado, this robot, Holly, is working the morning rush. Holly is cutting the drive through time by 10 to 15 seconds.For 20 years, worker Orlina has been taking orders and serving up food. She says Holly is one of the most helpful employees on staff. “It’s really fast and helps us with the speed a lot,” she says.The creator behind this artificial intelligence technology is Valyant. Rob Carpenter, the CEO of the company, says as jobs evolve and change, new jobs become available. As with most new technology, Carpenter says they’re still working out all the kinks. “It’s almost understanding the almost infinite ways to that people can ask for a cheeseburger,” Carpenter explains. “There are also the different accents you have to content with and the background noises.” While customers find the idea of Holly fun, their still unsure. “It was awkward,” says one customer. “And humans are just better and more responsive and talkative.” Carpenter admits Holly isn't the perfect employee, but he says in the next five years, you will see more robots at big name stores and fast-food restaurants."Right now, this is ground zero handling drive through,” he says. “Eventually, we are going to start seeing it in more tangible ways, where it can actually carry on a more fluid conversation." Carpenter says the opportunities are limitless. 1410

President Donald Trump said tonight that he has signed an executive order to shut down the use of Chinese-based social media applications TikTok and WeChat in 45 days.The order specifically prohibits any U.S. transactions with TikTok's parent company, ByteDance, starting on Sept. 20.Trump cited privacy concerns for taking the action against the social media networks.TikTok in particular has gained popularity among younger Americans in recent months for its short, entertaining video clips. The TikTok community has often been critical of Trump. Earlier in the summer, users of TikTok organized by reserving tickets to Trump’s rally in Tulsa, which failed to draw the type of crowds the Trump campaign expected.Trump said in his order that WeChat and TikTok “automatically captures vast swaths of information from its users -- threatens to allow the Chinese Communist Party access to Americans’ personal and proprietary information. In addition, WeChat captures the personal and proprietary information of Chinese nationals visiting the United States, thereby allowing the Chinese Communist Party a mechanism for keeping tabs on Chinese citizens who may be enjoying the benefits of a free society for the first time in their lives.”The Trump administration has complained that the application takes data and is used by the Chinese government."All the things that you care that you want to make sure the Chinese Communist Party doesn’t have, we have a responsibility to make sure that the systems that you’re using don’t give them access to that," US Secretary of State Mike Pompeo said two weeks ago.After Trump first said he would ban TikTok in the US last week, TikTok responded by saying in a post on Twitter, “We’re not planning on going anywhere.”Trump said earlier this week he is open to changing his mind if TikTok is sold to an American company. "But if somebody and whether it's Microsoft or somebody else buys it, that'll be interesting," Trump said. "I did say that, if you buy it, whatever the price is that goes to whoever owns it, because I guess it's China essentially, but more than anything else, I said, a very substantial portion of that price is going to have to come into the treasury of the United States because we're making it possible for this deal to happen." 2313
