Both Uber and Lyft are suspending their Pool and Shared ride options as the companies work to limit personal interactions amid the outbreak of COVID-19, the illness caused by the new coronavirus. Uber was first to announce Tuesday morning that it’s suspending its Pool option in the United States, Canada, London and Paris. The Pool option matches riders heading in the same direction, so they can share the ride and cost. “Our goal is to help 456

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

It’s two weeks after Election Day, and President Donald Trump still refuses to concede that he lost the battle for the White House. Recounts underway are not expected to change the result. Democrat Joe Biden captured enough electoral votes to become the next President of the United States at noon on Jan 20.But what if Donald Trump refuses to leave the White House and keeps fighting?Seem far-fetched? Perhaps. But Monday morning, Trump tweeted, “I won the election!” And then, a little later, “The Radical Left Democrats, working with their partner, the Fake News Media, are trying to STEAL this Election. We won’t let them!” The Radical Left Democrats, working with their partner, the Fake News Media, are trying to STEAL this Election. We won’t let them!— Donald J. Trump (@realDonaldTrump) November 16, 2020 So, what may have once been unthinkable seems like a valid question to ask.PIX11 put the question to five leading election law scholars. What would happen if President Trump refused to leave, assuming the electoral votes cast on Electoral College Day (Dec. 14) go as expected and Joe Biden gets more than half the 538 available.“The important thing is not whether he is physically in the White House,” said Michael Dimino of Widener University Commonwealth Law School in Harrisburg, PA. “The important thing is who is permitted to exercise the powers of the presidency. The Constitution establishes a procedure for deciding that question.”That means Donald Trump no longer would have any authority.Professor Justin Levitt of Loyola Law School in Los Angeles told us, “The states will certify their results, the electors will cast their votes, Congress will count those votes … and then we’ve got a new President. And at noon on the 20th. … the only way that Donald Trump will be permitted on White House grounds is if he’s invited.”Richard Briffault, an authority on election law at Columbia Law School put it this way, “I also assume that at noon on January 20, he becomes a trespasser and possibly a security risk and could be removed.”Presumably, any forced removal would be handled by the same agency that protected President Trump during his term, the Secret Service.Rebecca Green, the co-director of the Election Law Program at William & Mary Law School, described what the new president could do to resolve any problem.“If Joe Biden is duly elected president and Trump refuses to leave the White House, Biden will order that Trump be escorted from White House grounds,” Green said.Another expert, whom we’re not naming because the professor is under contract as an election analyst with another media outlet, agreed that if Donald Trump stays in the White House, he’d be a trespasser and “he’d be escorted out if it came to that.”"Nobody can retain the powers of the presidency by refusing to leave,” Professor Dimono summed up. He underscored that the country is a nation of law. “It is the votes of the electors -- as counted by Congress -- that determine who can exercise the powers of the presidency," Dimono said.So, one way or the other, Donald Trump would have to vacate the premises. This story was first reported by Allen Levine at PIX11 in New York, New York. 3230

  

Hundreds of people had to be rescued from fast-rising flood waters in the Midwest as several areas dealt with historic flooding that washed out roads and bridges.For many, all they have left is what they could grab from their homes before fleeing. Outside Omaha, Nebraska, animal rescue groups worked to save dozens of farm animals in the area, but others had to be left behind. Weather experts say, so far, 38 spots in the Midwest have reported record-high river levels, most of it caused by rain and melting snow. More evacuations could be on the way as floodwaters head downstream.The governors in Nebraska, Iowa and Wisconsin have declared states of emergency, and some areas could see more chances of rain throughout the week. 745

  

AURORA, Colo. -- For a two-and-a-half-month-old baby, Huntleigh has gone through a lot. She was born with her organs outside her body due to a rare birth defect called Omphalocele. "Omphalocele is a developmental anomaly that is a failure of the normal enfolding of the baby during development,” said Dr. Ken Liechty, a pediatric and fetal surgeon at Children's Hospital Colorado. Basically, omphalocele means organs like the stomach, bowel, and intestines are outside the baby’s abdominal wall, but still inside a sack. Surgeons are challenged with assessing each individual case and getting those organs back into the baby’s body. Thankfully, for Huntleigh, that surgical correction was possible almost immediately after birth. "Her organs and intestine were slowly reduced back into her abdomen – similar to rolling up a tube of toothpaste where you’re slowly pushing things back down into the abdomen and then closing the muscles over it,” Dr. Liechty said. Every case is different, and some are more severe. But overall, the birth defect is quite rare. According to 1084
