ALISO VIEJO, Calif. -- The woman killed in an explosion authorities believe was intentional in Orange County Tuesday has been identified as Ildiko Krajnyak-Vestil of Trabuco Canyon.The explosion happened from the inside of the two-story medical facility located on 5 Mareblu just after 1 p.m.The person who died was inside the building at the time of the blast. Authorities first believed a car had crashed into the side of the building but later said that isn’t the case.The FBI and a bomb squad were sent to the scene to assess the situation and investigate the cause of the explosion.At a press conference Wednesday afternoon, the FBI said they ruled out any accidental cause of the explosion, saying they believe the incident was intentional. An FBI official said there were items found at the scene that were inconsistent with what would be at the medical facility. A motive is unclear at this time and authorities say they haven't arrested any suspects. Officials told KABC that the medical facility appeared to be under construction. A preschool in the area was ordered to evacuate as a precaution after the explosion. Authorities held a news conference giving an update on the investigation Wednesday afternoon.

A woman in Oklahoma is warning people to stay home and isolate if they feel sick, even if they have a negative COVID-19 test. "Don't trust a negative COVID test. If you have the symptoms, especially that loss of taste and smell, you have to stay home,” Lesley Shollmier told local media.Shollmier should know, she had three negative tests before a fourth one came back positive.A few days before Thanksgiving, she started feeling sick, so she took a PCR test and it came back negative. Then a day or two later, she felt more sick and fatigued, and had a rapid COVID-19 test to be sure she was negative before spending Thanksgiving with family. That test also came back negative.Her and her husband had a small Thanksgiving with her mother, brother and sister-in-law.The day after Thanksgiving, Shollmier tells CNN she made a cup of tea and slice of pumpkin pie, when she realized she couldn’t taste or smell."I immediately knew, this is COVID. I just knew that that was one of the classic symptoms and regardless of anything, I have to have it. As odd as it sounds, I was fortunate to have that symptom so that I knew for sure that I was doing the right thing,” Shollmier told KTUL.She went to a different testing site and took a PCR test. The next day, those results came back negative.Her symptoms got worse, congestion moved into her chest, so she self-quarantined in her home keeping away from her husband on the second floor.She took another PCR test for COVID-19 on November 30, and again, results came back negative.She continued to isolate as symptoms got worse, now including back aches, shortness of breath, congestion and fatigue."I just assumed 100% I had COVID-19 and the last thing I wanted to do was infect someone,” Shollmier said.On December 2, she reached out to her doctor and asked to take a fourth PCR test.Finally, after having symptoms for 12 days, Shollmier finally had a positive COVID-19 test result.The FDA says molecular tests, like the PCR test, look for the virus’ genetic material and most are done with nasal swabs or throat swabs, and are typically highly accurate.Health experts agree with Shollmier’s decision to isolate even without a positive test result. A study published in August showed that people who took a test on the day they started showing symptoms had a false-negative rate of 38%. Even three days later, those who had COVID-19 with symptoms still had a false-negative test rate of 20%.After Thanksgiving, the White House coronavirus task force urged Americans who traveled for the holiday to assume they were likely infected and to isolate on their own. Shollmier is sharing her story as a warning to others."Listen to your gut. Know when you're sick and when you need to stay home. And just because you get that negative test doesn't mean that you're negative,” Shollmier told KTUL.She is still dealing with lingering symptoms. She tells CNN her family has been tested twice so far, and no one has symptoms or has tested positive. 2989

ALBANY, Ga. -- Located in the southwest part of Georgia, the city of Albany, which boasts a population of 75,000, is reclusive.It is three hours from Atlanta and more than an hour and a half from Tallahassee, the city with the closest major airport. And perhaps that is why the city is so self-reliant and resilient.“This is who our people are,” said Barbara Holmes, CEO of the Albany Chamber of Commerce.In 2017, a string of tornadoes battered the city, killing five people and causing more than billion in damage.Only a year later, in October 2018, Hurricane Michael ripped through the area as a Category 3 storm.Then, this past March, Albany became Georgia’s hotbed for COVID-19 as it quickly amassed the highest number of positive coronavirus cases per capita in the state. Dougherty County, the county in which Albany resides, had 1,700 cases per 100,000 people, while Fulton County, the state’s most populous county where Atlanta is, saw 280 cases per 100,000 people.Like so many cities across the country, the virus hit Albany’s workforce hard.“The business impact was immediate, right? It was a swift arc,” said Holmes.“Our business volume was way off. People were absolutely scared,” added Tim Underwood, who owns a local restuarant called The Rocket. “It was very scary because in my own home that meant my wife was home with the kids. She wasn’t working and she wasn’t able to work.”What made Albany’s case of unemployment unique, however, is there were no guidelines. It was the first outbreak in the state, so local business officials had to improvise to stay open before guidelines were issued by the Gerogia Department of Public Health and Governor Brian Kemp.And that’s where the beauty in Albany’s survival story lies.Shortly after business owners noticed the rise in the coronavirus cases, and before the governor issued any orders, 12 businesses in the community came together to figure out a plan that involved voluntarily closing their dining rooms and moving to take-out only.“Our concern was not only our business, but our community,” said Underwood. “We wanted them to know we were there for them. This was what we were going to have to do to survive quickly.”Underwood quickly slashed his staffing, took a large pay cut and set a budgetary minimum of ,000 per week in revenue. He says that was the number that would allow his restaurant to survive. Anything less and it would have to close.Week one, Tim says he made ,027.“There’s many of our staff still only working part-time hours, but they’re still working part-time hours and that’s better than not able to work,” said Underwood.Because of the effort, not a single one of Albany’s stores has closed for good. Yes, workers are fuloughed, but there is hope that at some point that work might come back."You know, it’s inspiring and it's encouraging, but what I will say to that is it’s not surprising because this is who Albany is,” said Holmes.“We’re here to help each other, and I think that’s what gets lost in all of this,” said Underwood. “And I think that’s why, at least in Albany, when you see us coming out I see a brighter future." 3136

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
