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

Actress Felicity Huffman is reportedly heading back to television to star in an upcoming ABC sitcom.A year after serving 11 days of a two-week sentence for her role in the college admissions bribery scheme, Deadline reports that Huffman is starring in a new pilot commissioned by ABC.The untitled comedy stars Huffman as a widowed woman who inherits her husband's baseball team.It was inspired by Susan Savage, who owns the Sacramento River Cats, the Triple-A affiliate of the San Francisco Giants.Actor Zack Gottsagen will play Huffman's onscreen son, a baseball devotee with Down syndrome, according to The Hollywood Reporter.According to Deadline, Hartman Edwards will write and will also be an executive producer with Huffman, Kapital Entertainment's Aaron Kaplan and Dana Honor, Joel Zadak of Artists First, and Savage. Gottsagen will also produce. 861

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

Actor Dwayne Johnson is among the investors who submitted a winning bid for the XFL — the professional football league which was in the midst of its first season when the COVID-19 pandemic cut it short.Johnson, Dany Garcia and RedBird Capital Partners combined to purchase the league for million, according to the press release. The sale is subject to bankruptcy court approval at a hearing on Friday.“The acquisition of the XFL ... is an investment for me that’s rooted deeply in two things - my passion for the game and my desire to always take care of the fans,” Johnson said in a statement. “With pride and gratitude for all that I’ve built with my own two hands, I plan to apply these callouses to the XFL, and look forward to creating something special for the players, fans, and everyone involved for the love of football.”Prior to joining WWE, Johnson played college football at the University of Miami, where he won a national championship in 1991. He later played professionally for the Calgary Stampeders of the Canadian Football League for one season.The XFL kicked off its inaugural season earlier this year with the goal of serving as a springtime development league for NFL hopefuls. The league consisted of eight teams, mainly composed of former college and NFL players. Despite modest TV ratings and an early buzz, the league closed operations in April after the COVID-19 pandemic shut down sporting events.The league is the second iteration of the XFL. In 2001, McMahon launched a football league by the same name that relied heavily on wrestling-style antics as an enticement for viewers. The league folded after one season. 1655

A woman known to authorities as a prostitute is accused of setting up one of her Johns to be robbed.Palm Beach County Sheriff’s Office detectives say Christina Chiesa, 36, had sex with a man for money and then signaled for Robert Jones, 26, and two other men to steal from him. Surveillance video captured the victim having sex with Chiesa behind a dumpster behind a shopping plaza in suburban West Palm Beach on April 10, according to an arrest report.Jones is seen on video walking up to them, pulling out a knife, swinging it at the victim, the report states. “I’m gonna open you up, give me the money,” Jones allegedly told the victim.The victim told detectives he was able to fight off Jones until Chiesa signaled for two other men to come over. He said the men punched and cut him in the face. He said one of the wounds was so deep that he needed stitches. The suspects stole 0 out of his wallet and his beach cruiser bicycle. He said he was able to grab his wallet back from Chiesa.Days later, a deputy recognized Chiesa and Jones from the surveillance video. The two other men were not identified in the report.Chiesa was arrested on April 11 and Jones was arrested on April 13. They are being held at the Palm Beach County Jail without bond. They are facing charges of robbery and aggravated battery.Chiesa has been convicted of prostitution three times in Palm Beach County. 1435
