ALPINE (CNS) - A motorcyclist was killed Friday afternoon in a collision with a truck on a rural East County road.The crash occurred shortly before 4 p.m. on Japatul Valley Road, near Bell Bluff Truck Trail in the Alpine area, according to the California Highway Patrol.The motorcyclist died at the scene of the accident, which left the two-lane roadway blocked into the early evening, the CHP reported.The victim's name was not immediately available. 459

After three full days of deliberations, the jury in the trial of former Trump campaign chairman Paul Manafort still has not returned a verdict.Jurors will return Tuesday at 9:30 a.m. ET.Manafort is charged with 18 counts of tax evasion, bank fraud and hiding foreign bank accounts in the first case brought to trial by special counsel Robert Mueller as part of the investigation into Russian interference in the 2016 US election. He has pleaded not guilty to all the charges.Judge T.S. Ellis and both teams of lawyers met twice met Monday morning in private. The conversations lasted about 10 minutes each, and Ellis said transcripts will be made public at the end of the trial.The trial carries major implications for the future of Mueller's investigation. Trump has repeatedly called the probe a "witch hunt" that hasn't found evidence of Russian collusion with his campaign, and his allies in and out of the White House say the special counsel should wrap things up. 977

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 country, YMCA locations are back in business.That means members are working out inside gyms again, doing everything from running on treadmills to lifting heavy weights.Now, in an effort to create an even safer environment for its members, the Downtown Denver YMCA is taking its group exercise classes outside.“My first priority inside before COVID and now with COVID is to keep them safe,” group exercise instructor Lamar Sims said about member safety.After reopening, Sims is leading a strength and conditioning class on the steps of the Colorado State Capitol Building.This former district attorney turned group exercise instructor isn’t sure how COVID-19 will impact his class sizes. But he’s absolutely sure that safety is a priority for the millions of YMCA members.“We’re working on making sure people are doing good spacing,” he said. “So, we are not going to have any of the partner type exercises, partner spotting, partner stretching that we used to do.”Infectious disease specialists say this kind of spacing is paramount during the pandemic.“If you’re able to have that distancing there’s less spread,” said Sheryl Zajdowicz, Ph.D., a biology professor at Metropolitan State University of Denver.Zajdowicz believes exercising is much safer outside than inside but says there are still several concerns with intense training in a group setting.“When you’re working out, you’re breathing heavier and potentially coughing and there’s still some risk that could be associated there,” she said.That risk, however, is worth it to some members.“There’s nothing like it,” Paul Garland said about group exercise classes. “This is the one thing that I miss the most about the whole shelter in place.”Garland says this kind of workout impacts his mind and his body.“The better I feel physically, the better I feel emotionally,” he said.Moving forward, the YMCA will continue to do group exercise classes outside as long as COVID-19 is still a concern. 1971

Almost a decade ago, Matt Wilson went to the emergency room after experiencing a lot of pain. It was pretty clear he had a kidney stone, but the doctors wanted to take a look to be sure.“After they identified the kidney stone, they told me I had a shadow in my pancreas," said Wilson.That shadow would lead to a few months without answers.“Went through testing and went through months of tests without knowing what it is, but they wouldn’t rule anything out. The months of not knowing were stressful. They were stressful on me, they were on my family,” said Wilson.Finally, after visiting a specialist in Philadelphia, he finally got an answer.“They said I had a cancerous tumor on the tail of my pancreas. I went in for a kidney stone and came out with a diagnosis of pancreatic cancer,” he recalled.Wilson knew he wanted to fight. He underwent surgery to remove part of his pancreas, his spleen, and 21 lymph nodes.Wilson has survived for nine years since his diagnosis. According to the American Cancer Association, the five-year survival rate for pancreatic cancer is just 9 percent.“It is one of the deadliest cancers,” said Julie Fleshman, the CEO of the Pancreatic Cancer Action Network. The group raises money and awareness for pancreatic cancer. She wants people to know why it’s such a hard disease to detect.“The symptoms of pancreatic cancer are quite vague. There’s things like stomach pain and back pain, unexplained weight loss. Things that could be associated with other diseases, so it’s not usually the first thing that someone thinks of as oh, maybe it’s pancreatic cancer,” said Fleshman.In addition to unclear symptoms, there’s no early detection test like you might have with other cancers."Usually, by the time it’s diagnosed, it’s late stage. It’s already metastasized or spread to other organs, and it’s more difficult to treat at that point,” said Fleshman.But Fleshman and Wilson hope the efforts of organizations like PanCan will lead to an early detection test and more treatments to help save lives.“I actually really think that it’s possible that in the next decade for us to have an early detection strategy,” said Fleshman.“My hope is that we continue to make advances. That we can have early detection for people for pancreatic cancer in the future, and I think we will get there. And that will continue to improve patient outcomes and improve the survival rate of this disease,” said Wilson. 2435
