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

Across the West Coast, entire towns are being leveled by historic wildfires, and one northern California county is facing this horror for the second time in two years.Berry Creek’s hilly terrain is still smoldering, as homeowners anxiously wait to be let back into the area, although many already know they don’t have homes to come back to.“When they see the smoke or hear about a fire, their PTSD, whether you’re civilian or former military, it kicks in,” said resident Michael Zylstra, who evacuated from his home.Steve Kaufmann, the public information officer for the California Department of Forestry and Fire Protection, compared the fires to a freight train.A freight train of fire, swallowing everything in its path.“When we have a fire like this, it makes for number one, explosive, but we are seeing erratic fire behavior we’ve never seen in our career,” Kaufmann said.Fires so erratic it’s capable of leaving a town unrecognizable.Michael Zylstra says his aunt and uncle won’t have a home to come back to. Miles of Berry Creek homes have been reduced to rubble.“It’s a scenario where the vegetation is completely bone dry,” he described.The town is a casualty of the North Complex Fire. Fueled by years of drought and extreme winds, it’s burned over 260,000 acres in northern California.“It took a huge toll on the community,” Kaufmann recalled. “It hit because it moved so fast, and we just didn’t have the resources to put in there to defend every structure involved.”With resources spread across 28 major fires, Kaufmann says it’s a challenge the state has had to adapt to.“We’re always prepared for the worst-case scenario,” he said. “This is probably definitely one of the worst cases we’ve seen in years.”Zylstra evacuated his home six days ago in the nearby town of Cherokee. As he waits for news, he helps fellow veterans cope with the trauma.“It’s been stressful,” he said. “They’re anxious, they get nervous, they don’t know what to do, they can’t sleep.”In large part because the community went through this nearly two years ago when the Camp Fire ripped through paradise killing 85 people and destroying nearly 19,000 structures.“It’s very painful memories for a lot of them,” Zylstra said.It’s painful for many to rebuild.“[In] a lot of people’s eyes, it will never be what it was; it will never ever be what it was in 20-30 years, what it used to be,” he said.And now, another town must also try and navigate life forever changed by fire.“We just need to all work together for that one common goal, to take care of each other,” Zylstra said. 2573

After losing her mother to COVID-19, a comedian has launched a mask-wearing crusade.Through a pixilated image on her iPad, Laurie Kilmartin strained her eyes desperately hoping to see her mother’s chest rise on the other end of their Facetime call, but after five minutes of silence, Laurie knew the coronavirus had won.Joanne Kilmartin died alone inside a California nursing home.After an hour of crying into her screen, Laurie and her sister told doctors it would be okay to end the call. They had spent the last 69 hours on FaceTime with their mom, knowing the end of her life was near.“Facetime makes this noise when it closes out and it closes out immediately, it doesn’t go to a corner and fade away. So, my mom just disappeared. There was this noise and she was pulled back into the universe,” Laurie said via a Zoom call from her home in California.Just weeks earlier, Joanne, 82, was enjoying her evening vodka martini at Laurie’s home where she’d been living. The 82-year-old had some underlying health issues but for the most part was doing okay, until one day when she started suffering from shortness of breath.Knowing what she knows now, Laurie says she likely would’ve never let her mom be checked into a short-term care facility after being discharged from a local emergency room.“It didn’t occur to me at all that this was still running through nursing homes like that,” she explained.When Joanne was checked into York Healthcare & Wellness Centre in Highland Park, California, not a single person had COVID-19. But just days later, dozens of patients had suddenly contracted the virus. After testing positive, Joanne’s condition quickly went downhill.“I couldn’t rescue her. Had I known what would happen, I would’ve gotten her a hotel room and hired a nurse,” Laurie lamented.By the time it became clear that Joanne wasn’t going to survive the virus, doctors set up an iPad in her room. Laurie and other family members would spend hours just watching their mom breath, offering words of comfort at any hint of movement. All of it done virtually in an attempt to keep the virus from spreading.COVID-19 has robbed families of the opportunity to grieve together in person.“My mom got the worst send off and at the end we were only voices that we hoped she could hear. It’s a terrible way to say goodbye to somebody, it doesn’t feel real,” Laurie said about her mom’s death.But Laurie has tried to find some purpose in her pain. As a professional comedian with a large online social media following, she decided to chronicle her mom’s final days of Twitter. It was an effort, she said, to educate the public about the true scope of the kind of suffering the virus causes. Laurie has even used her platform to criticize people who push back against mask-wearing policies.“To someone who doesn’t want to wear a mask, you’re incredibly selfish, you’re harming yourself. Even if you think, ‘Oh it’s just old people,’ do you want to lose an old person like this? Is this how you want your grandma or grandpa to go out? Is that fair?” she questioned.Having watched her mother take her final few breaths via a FaceTime call, Laurie is left to wonder why so many states are reopening as quickly as they have, even as COVID-19 cases continue to spike.“There’s over 100,000 stories like mine, and 100,000 families like mine that are shocked and numb, you could be me pretty soon.” 3397

A woman has been arrested after allegedly trying to suffocate her 7-month-old son.Authorities said they took 23-year-old Jennifer Sandor, of Goodlettsville, Tennessee, into custody and charged her with attempted criminal homicide after she allegedly tried to suffocate her son, who was a patient at Vanderbilt Children’s Hospital.Sandor had taken her baby to the hospital for unexplained medical episodes that left the child blue and limp.On Friday, staff at the hospital said they witnessed Sandor use her hands to cover her son’s mouth and nose, preventing the baby from breathing.Reports stated the child was in obvious distress. They added he was struggling to free himself.Authorities said Sandor released the child only after staff intervened.         Sandor was being held in lieu of a 0,000 bond. 860

ALHAMBRA, Calif. (CNS and KGTV) - A sheriff's deputy who was shot in the head in an apparently unprovoked attack at an Alhambra fast-food eatery was on life support Wednesday, while a Utah man with ties to San Diego County remained jailed for allegedly shooting the lawman and possibly killing a man in downtown Los Angeles. Rhett Nelson, 30, of St. George, Utah, was taken into custody around 10:40 a.m. Tuesday by Long Beach police in the 2400 block of Granada Avenue and later turned over to Los Angeles County Sheriff's Department investigators, who arrested him. San Diego Police say Nelson is under investigation in connection with five seperate convenience store robberies across San Diego County. From June 7-9, four 7-Eleven stores and a Circle K were held up at gunpoint. In each case, the clerk turned over cash and the man left the scene before police arrived.Officers are reviewing surveillance video from the San Diego cases.Nelson is suspected in the shooting of Deputy Joseph Gilbert Solano, who was at the counter of a Jack in the Box restaurant at 2531 W. Valley Blvd. in Alhambra around 5:45 p.m. Monday when he was shot in the back of the head in what sheriff's officials believe was a random attack. Los Angeles police Chief Michel Moore said Nelson is also suspected in a fatal shooting that occurred about an hour earlier in the 1900 block of East Seventh Place, between Santa Fe Avenue and Alameda Street, in the downtown area. That shooting, apparently done from inside a vehicle, left an unidentified 30-year-old man dead. Sheriff Alex Villanueva said Tuesday that Solano was on life support in grave condition at County-USC Medical Center. ``Please continue to pray for our brother Deputy Joseph Gilbert Solano, who continues to fight for his life in the ICU,'' Villanueva wrote on Twitter Wednesday morning. ``Thank you to everyone who have been sending prayers and words of support.'' The sheriff's department on Wednesday released a booking photo of Nelson. ``Investigators believe there is a possibility suspect Rhett Nelson may have been involved in additional criminal incidents since entering California,'' according to the department. ``With the public's interest in mind, the booking photo is being released in an effort to seek any possible additional victims.'' Anyone with information was urged to call the Los Angeles County Sheriff's Homicide Bureau at 323-890-5500, or Crime Stoppers at 800-222-TIPS. At a news conference on Tuesday afternoon, sheriiff's Capt. Kent Wegener told reporters that Nelson walked into a Long Beach church around 10 a.m. Tuesday, called his father in Utah and talked about carrying out a pair of shootings. ``During that call he referred to committing murder in Southern California, obviously concerning his father,'' Wegener said. ``The father called (the) Long Beach Police Department to report what his son had told him. Long Beach did a reverse directory on the phone number provided by the father and responded to that church.'' Pastor Brad Paradee said when Nelson arrived at First Nazarene Church at 2280 Clark Ave., he considered him homeless. ``I was with him for one to two hours,'' Paradee told the Daily News. ``I gave him food and coffee, let him use my phone to call home and take a shower. He had the gun with him the whole time.'' A short time later, Nelson was seen driving away from the church, and police took him into custody him without incident after he pulled into the driveway of a home on Granada Avenue, Wegener said. The hat and maroon shirt the gunman wore during the Jack in the Box shooting ``were clearly visible in the rear seat of his car,'' he said. The suspect and the vehicle -- a Kia Sorento SUV -- also matched the description of those involved in the shooting, according to the captain. A revolver ``matching the gun used in the assault'' was found inside the vehicle when a search warrant was served, Wegener said. Nelson's father, Bradley, issued a statement Tuesday regarding his son's arrest. ``My wife Jean and I, along with our family, are saddened beyond words to hear of the shooting of Los Angeles Sheriff's Deputy Joseph Solano, and to learn that our son Rhett is being held in connection with this horrifying and senseless attack,'' Bradley Nelson said. ``We are cooperating fully with authorities and will provide them with all information they request concerning Rhett and his struggles. We ask that people please pray for Deputy Solano and his family.'' There was no word on why Solano was shot or if the gunman knew he was a sheriff's deputy. Solano, 50, was not in uniform and was not carrying a gun or badge or anything that would indicate he was a law enforcement officer, authorities said. Solano -- a 13-year department veteran described as a dedicated family man -- had just dropped off his mother's vehicle to be serviced at a Jiffy Lube near the Jack in the Box restaurant where he was shot, Villanueva said. He noted that Solano's father had recently died, and the deputy was the sole provider for his mother. ``We're praying for his recovery,'' Villanueva said of the wounded deputy. ``This is the part of this job that I don't relish and I always dreaded this day would happen. It happened way too soon.'' Villanueva described Solano as a ``kind-hearted, generous person'' who was always willing to help others. Sheriff's officials said Nelson's relatives in Utah had recently reported him missing, with Wegener telling reporters that the suspect had arrived in Southern California around the first week of June. Nelson's father posted a photo of his son on Facebook on May 30 asking for help finding him, noting he had last been seen in southern Utah in his white 2012 Kia Sorento and that he had a history of drug abuse. ``Our 30 year old son Rhett Nelson disappeared 3 days ago, taking nothing with him but his phone, leaving all his clothing and his computer behind,'' Bradley Nelson wrote. ``We've had no contact with him, his phone is dead or off since then. He has a history of opiate abuse and has been clean for about 6 months, but we know what a terrible struggle that is. We are praying for his safe return.'' By the first week of June, Rhett had made contact with relatives and told them he was in California, Capt. Mike Giles of the St. George Police Department told the Daily News. Moore said detectives developed a connection between the ``senseless attack'' on the deputy and the fatal shooting in downtown Los Angeles that occurred around 4:50 p.m. Monday. Moore said a 30-year-old man was standing in the 1900 block of East Seventh Place ``when a vehicle arrived and, according to other witnesses, an individual inside the vehicle had a brief exchange with our victim, gunfire erupted and our victim sustained at least one gunshot wound and died at the scene.'' ``We are led to believe that he (Nelson) is potentially responsible. We are led to that belief on the basis of the suspect Mr. Nelson's physical appearance, including some of his clothing, as well as the vehicle description,'' Moore said. Nelson was being held in lieu of million bail, according to sheriff's inmate records. Nelson had a misdemeanor drug conviction in Salt Lake City in December 2014, but no other criminal history. 7257
