ALPINE COUNTY, Calif. – One small county in California has become a safe haven from the coronavirus. There’s only been one reported case of COVID-19 since the start of the pandemic, but now, hundreds of visitors from across the country are going there to vacation.“I have never seen this many people here,” said Deanna Jang, the owner of the general store in the county.Business owners like Jang worry the visitors they rely on may bring more problems than profit. “It’s been very good for business, it’s scary though because you just don’t know what’s going to happen,” said Jang.Jang’s family has owned a local general store for decades. She’s nervously watching as cases rise in counties all around hers. She fears a summer shutdown in this tourist town could take her family business with it.“You need to make your year’s income here in two months because the rest of the months you just kind of get by,” she said. “It’s scary, it’s like, ‘What does this mean for next year, and the year after?’ Because we’d have to recover from that.”“It’s sort of a double-edged sword of wanting to get our economy started and worrying that the people who are supporting the economy are going to bring COVID into our community,” said Nichole Williamson of the Alpine County Health Department.Williamson said the worry has locals considering what would typically be unthinkable there. “We have had people who work in the short-term rental business tell us they would not be upset if we limited short-term rentals right now,” she said.One driving concern: the county has few medical resources.“We have no private physicians, no hospitals, and we have a two-day a week family clinic with a nurse practitioner, and she was called up into active duty in the Army,” said Williamson.First responders are also in short supply. “If we had a few law enforcement and a few firefighters exposed, we’d be in a very vulnerable situation,” said Williamson.But with this vulnerability comes a choice: to fear the virus or face it. “You just have to learn to live with it,” said Jang.For hotel owner John Flannigan, there is no choice. He said he is making safety his top priority to make sure his business can stay open. “The economy is in its worst case,” said Flannigan. “It’s worse than 2001 and 2008 combined, times ten, so I don’t think we should be hurting anyone’s ability to make a living. I think we should be figuring out solutions so they can make a living.” Flannigan runs Sorenson’s Resort and has moved all his dining to be outdoor, open air and is making sure guests have space to spread out and social distance.As worried as many community members are, they hope they can keep business going safely.“It’s not about me. It’s not about you. It’s about everyone,” said Jang. 2769

According to a recent paper, the Earth is caught directly in the crosshairs of a cosmic hurricane.A swarm of nearly 100 stars, accompanied by an even greater amount of dark matter, is aimed directly at our stellar neighborhood and there's nothing we can do to stop it; in fact, the vanguard is already upon us. This sounds like a perfect summer blockbuster movie, starring The Rock and Chris Pratt, or maybe Scarlett Johansson and Charlize Theron.Except this is for real. But is it a danger? Well, actually, no. Not at all. But it's potentially incredibly fascinating, with lots of interesting scientific interconnections. So, what is really going on?The story starts last April, when the Gaia satellite announced the locations and trajectories of 2 billion stars in the vicinity of the Milky Way surrounding our sun. They released the data to the public.Scientists were then able to look at the data set to see if they could spot anything peculiar. In galaxies like the Milky Way, the most common behavior is that the stars orbit the center of the galaxy in a manner broadly similar to the planets orbiting our sun. However, there are some stars that exhibit unusual motion. About a year ago, astronomers identified some "stellar streams" passing through our celestial neighborhood.One of them, called S1 (for stream 1), consists of nearly 100 stars of similar age and composition, orbiting the Milky Way in a direction exactly opposite that of normal stars. It's kind of like a handful of cars driving the wrong way down the highway, except with a much greater distance between them and with no likelihood of a collision. These stars are spread out over a few thousand light years and they will pass through the solar system's neighborhood over the course of a few million years.Astronomers identified S1 as being part of the remnants of a dwarf galaxy that collided with the Milky Way and was consumed in an epic episode of cosmic cannibalism. Dwarf galaxies are very small, typically about 1% the mass of the Milky Way. They can orbit larger galaxies and collide with the bigger galaxy, adding their mass to the parent. This is what appears to have happened in the case of S1, although the process has taken probably a billion years.Dwarf galaxies often have a disproportionately large fraction of dark matter. Dark matter is a hypothetical and still-undiscovered form of matter that interacts only gravitationally. Scientists have proposed its existence to explain many astronomical mysteries, for example the observation that most galaxies rotate faster than can be explained by the known laws of physics and the stars and gas of which they are composed.While dark matter has not yet been observed, hypothesizing its existence is the simplest and most economical explanation for myriad astronomical mysteries. Averaged over the entire universe, dark matter is thought to be five times more prevalent than the ordinary mass of stars and gas and planets.In dwarf galaxies, the fraction of dark matter is often higher. In Fornax, a well-studied dwarf galaxy orbiting the Milky Way, researchers estimate that the dark matter is between 10 and 100 times greater than the mass found in its stars.If that number holds for S1, the dark matter of the S1 stream is passing through the Earth at a much higher velocity than the more ordinary dark matter that orbits the Milky Way -- about twice as fast. It is thought that S1 dark matter is flying through the solar system at a speed of about 550 km/s, or about 1.2 million mph. While these numbers are impressive, they are misleading. Dark matter, if it exists, is extremely diffuse and it will have no discernible effect on the solar system.Because dark matter hasn't been observed yet, these velocity numbers are speculative, although they are strongly supported by a very large body of evidence. However, the prospect of high velocity dark matter flying through the Earth has suggested an opportunity to detect it.In a paper in the prestigious journal Physical Review D, researcher Ciaran O'Hare and his collaborators calculated the possibilities of discovering dark matter using both existing and proposed dark matter detectors. They considered two varieties of dark matter particles: a very heavy kind called a WIMP (weakly interacting massive particle) and a very light kind called an axion. Because the ultimate nature of dark matter is not known, it is important to be open to all possibilities.They found that the detectors they evaluated could find WIMPs for certain ranges of the particle mass. However, when they looked at the axion possibility, it appeared the prospects were even better. Because of its light mass and the manner in which an axion would interact with the detector, the apparatus simply has a better chance of seeing the axion. (If axions exist, of course.)Experiments with names like ADMX, MADMAX and ABRACADABRA are able or will be able to search for the signatures of dark matter proposed in the recent paper. They consist of technologies that are designed to interact with axions in a strong magnetic field and convert them to ordinary microwaves or radio waves that can be easily detected.It's important to remember that the S1 stream poses no credible threat to the Earth and humanity. There is no need for an action hero to save us. However, the synergy of science is staggering. A careful catalog of nearby stars has opened the prospect of a better possibility of finding and identifying dark matter, which is one of the great unanswered mysteries of modern physics. It's an amazing time we live in, in which we can study such things.\ 5625

A wildfire burning in Arizona, just northeast of the Valley, is now the most massive fire actively burning in the country, according to officials.The wildfire has already demolished more than 114,000 acres, and it is just five percent contained, as of Thursday morning.The good news is no homes nor businesses have been destroyed, but some worry it is just a matter of time, as evacuations have been implemented in multiple towns.Fire crews say the wildfire has spread so rapidly and is difficult to contain because of the heat, low humidity, terrain, and high winds.The threat snuck up on Tonto Basin homeowners like Robyn Hill."I really wasn’t prepared for it. I thought the fire was too far away, and you are just kind of in disbelief," said Hill, who got the evacuation order Monday.Hill said she rushed home from her hair salon business in Payson once the alert came across her phone.She packed up the RV with her husband and two dogs, and they quickly left town."So when you got two hours to get your stuff and go. It would help if you were a little more prepared," she said. "I packed the bread and the peanut butter, but forgot the jelly."While the jelly makes for a good joke, leaving home was no laughing matter."You kind of shed a few tears as you leave the house because it’s my home, it’s my little paradise," said Hill, who tells KNXV she had just finished adding a pool and re-doing her garden and yard during the pandemic slowdown.While Hill and others are evacuating their homes, the Red Cross has been setting up shelters."[Monday] we had over a dozen people check-in," said Jim Gilloon, with the Arizona Red Cross. "We don’t just let them walk in. We do a screen test, we take their temperature, and we ask him questions, and then they are clear to come in."At the shelter, the people forced from their homes can get a meal, information, and then the Red Cross helps find them a place to stay for the night."It’s a wildfire season. So we are prepared," said Gilloon. "The fire is spreading, and there is no containment. So we are looking at several days, a week maybe."Many Arizonans from Punkin Center, Sunflower, and Apache Lake are now sleeping in motels.Casie Malinski though, stayed behind in her Tonto Basin home Tuesday to care for her many animals."This morning I took my older children into Payson and dropped them off with their things," said Malinski. "I have full faith in our hotshots and fire crews who are out here."As 440 firefighters desperately try to squelch the inferno, hundreds more are praying for them."I think everybody is just terrified and hoping they will get it out in time before the residences are lost," said Hill. "Let’s stop it on the highway, please. And before the homes."State Route 87, or the Beeline Highway, is closed from Payson to Bush Highway.State Route 188 is also closed from the 87 junctions to Roosevelt.Fire officials say the fire started due to a car issue on the side of the highway.KNXV's Zach Crenshaw first reported this story. 3008

  

Alek Minassian, the man accused of plowing into pedestrians with a van in Toronto on Monday, posted a cryptic message to Facebook minutes before setting off in his rented vehicle, Sgt. Graham Gibson, a homicide detective with the Toronto police, said Tuesday.CNN law enforcement analyst Josh Campbell said earlier that investigators told him they believe a post on Minassian's Facebook page refers to the man who killed six and injured 14 in a drive-by shooting and vehicle ramming attack near the University of California Santa Barbara campus in 2014. Elliot Rodger later died from an apparent self-inflicted gunshot wound.Minassian, was charged Tuesday with 10 counts of first-degree murder in a Toronto court.The 25-year-old is also charged with 13 counts of attempted murder.Minassian, who was wearing a white jumpsuit with his hands cuffed behind him, appeared attentive during the brief hearing. His next court appearance will be a bail hearing on May 10.Investigators are still trying to determine the motive behind the attack, which left 10 people dead and 15 hurt."Obviously all Canadians continue and will continue to have questions about why this happened, what could possibly be the motive behind it," Canadian Prime Minister Justin Trudeau said Tuesday.So far, officials aren't calling the attack an act of terrorism. "There would appear to be no national security connection," Canadian Public Safety Minister Ralph Goodale said.But Toronto Police Chief Mark Saunders said "it's very clear just from a general perspective to say that the actions definitely look deliberate."The van sped down a busy street Monday with reckless abandon, swerving into the wrong lanes of traffic and careening onto a sidewalk.Minassian was arrested in a white rental van less than 30 minutes after police received a 911 call, Saunders said.He said Toronto authorities hadn't had previous contact with the 25-year-old suspect. But a US law enforcement official with knowledge of the matter said Minassian was known to authorities.Clue emerges from FacebookInvestigators found a Facebook account they believe belongs to Minassian, CNN law enforcement analyst Josh Campbell said.A message posted on the account earlier Monday read: "All hail the Supreme Gentleman Elliot Rodger!"Campbell said investigators believe the post refers to the man who killed six and injured 14 in a drive-by shooting and vehicle ramming attack near the University of California Santa Barbara campus in 2014. Rodger later died from an apparent self-inflicted gunshot wound.Investigators said Rodger was motivated to carry out his attack by a personal grievance related to his immersion in the extremist ideological subculture of men's rights activists, who believe women don't actually want gender equality and have been brainwashed by feminist propaganda.A mile-long scene of carnageAuthorities said Minassian left a trail of destruction nearly a mile long, north of midtown Toronto."Based on witness accounts, we have a vehicle that started north on Yonge Street from Finch (Avenue) and drove southbound at some point in times on sidewalks, at some point in times driving southbound in northbound lanes," Saunders said, adding that it appeared to be a deliberate act.Ten people were transported to Sunnybrook Health Sciences Centre and two were declared dead at the hospital. Five patients there were in critical condition. Two other patients were taken to St. Michael's Hospital, but their conditions are unknown.'Scene from a war zone'Diego DeMatos was one of the good Samaritans who tried to save victims.DeMatos said he was driving north on Yonge when he saw the van driving fast southbound. He said he saw the van hit a man and a woman."Blood started gushing out of his head, and she was bleeding really badly, too," DeMatos told CNN.At first, he thought the collision was a hit-and-run. But then he noticed four to five victims on the ground as he drove a few meters further.DeMatos said he stopped to help another victim, who was already being aided by someone."I went over to try to perform CPR on him. ... He died in our arms," DeMatos said."It was like a scene from a war zone. There was garbage cans everywhere, broken bus shelters and mailboxes on the ground."A dramatic arrestCell phone video obtained by CNN partner CTV appears to show a tense standoff with a suspect after the incident. Police have not said whether the person in the video was Minassian.The footage appears to show a man standing in front of a white van with a damaged front bumper. The man is yelling and extending one arm, pointing an object at an officer standing behind a black car.The officer has his weapon drawn and pointed at the man. The officer slowly steps toward him and yells "Get down, get down!"Later in the video, the man is seen on the ground and the officer is cuffing his hands behind him; the object can be seen lying on the ground off to the side.As for whether the suspect had a weapon, "There's nothing that indicates he has a gun," Saunders said.Trudeau offered his condolences to the families of the victims. He thanked first responders, who he said "faced danger without hesitation, and their efforts no doubt saved lives and prevented further injuries.""We should all feel safe walking in our cities and communities," he said. "We are monitoring this situation closely, and will continue working with our law enforcement partners around the country to ensure the safety and security of all Canadians."The-CNN-Wire 5500

  

ALPINE, Calif. (CNS) - San Diego County officials opened an erosion control center in Alpine Thursday to help businesses and homeowners prevent debris flows in the areas burned by the Valley Fire.The center at 2914 Tavern Road will offer free sandbags, fiber rolls and other items to help residents stabilize properties before rains arrive and potentially trigger mudslides and debris flows, county officials said.Starting Thursday, the center will be open to business and property owners from 8 a.m. to 4 p.m. daily Monday through Saturday, and from 9 a.m. to 2 p.m. on Sundays. Appointments are not required this weekend, but will be required starting on Monday.Residents and business owners can schedule an appointment to pick up erosion control materials by calling the county's stormwater hotline at 888-846-0800.Staff will be available to advise on how to protect properties, homes, garages, sheds and other structures. Staff can also visually inspect properties and offer information on best practices to protect structures.As of Wednesday morning, the Valley Fire remained at 17,665 acres and was 90% contained, according to a Cleveland National Forest incident page.The conflagration, which broke out early on the afternoon of Sept. 5 off Spirit Trail and Carveacre Road in Japatul Valley, ultimately destroyed 30 residences and 31 outbuildings, damaged 11 other structures and left three firefighters injured, according to Cal Fire.Jamul resident Jim Grigsby told ABC 10News, “The fire burned down three of my neighbors' houses. And I’m looking out through my window now and it’s kind of sad ... We’ve been through three fires out here, and this is the first time it got this close so we had to get all of this stuff out.”On Thursday, Grigsby went to the erosion center to pick up “fiber coils or swaddle to divert water and use them to fil up the sandbags and build a retaining wall to the gullies on the property." 1934
