After Andy Cohen recovered from the coronavirus, he wanted to help others recover. He attempted to do what others who have had the coronavirus have been asked to do and give plasma.It turns out he was rejected.Cohen is prohibited from giving plasma because he is gay. He was told that gay men are unable to give blood due to concerns over HIV infection, despite him being HIV negative."They said, 'You can't do it,'" Cohen said on Tuesday’s ABC "The View." "I was hurt. I just thought well this is crazy, technology has come so far.“They're worried about HIV in blood," he added. "But I'm HIV negative. And you can find that out, and then you can test my blood a couple of times before putting it into a system."The FDA recently slightly relaxed its ban on gay men giving blood or plasma, stipulating that men who have had sex with other men are eligible to donate after three months of abstinence.The FDA says that it is possible that convalescent plasma contains antibodies to the coronavirus and might be effective against the infection. Plasma can be collected from recovered individuals only if they are eligible to donate blood. 1142

After spending 23 years in prison for a crime he did not commit, Nevest Coleman is back at work with the Chicago White Sox.Coleman, then a 25-year-old groundskeeper with the White Sox, was convicted of the 1994 rape and murder of a Chicago woman and sentenced to life in prison without parole.He was freed last year after DNA found on the victim was linked to a serial rapist.Friends and family contacted the White Sox after his release to help him get his old job back, CNN affiliate WGN reported.The team said it was grateful that "justice has been carried out for Nevest" and said they were happy to welcome him back to the team as one of its groundskeepers.Coleman told WGN that he watched Sox games while he was in prison and would see his former colleagues scramble to protect the field during rain delays.Two of his friends who are still on the grounds crew were there to greet him with big hugs on Monday morning when he arrived for his first day back on the job.He was issued a new uniform and hat. He then put on a big yellow rain suit to pressure wash the sidewalk and got to work.A lot has changed while Coleman was away. The stadium has had extensive renovations and is now known as Guaranteed Rate Field instead of Comiskey Park.One thing, however, has remained constant for Coleman."I was in a situation where I felt comfortable here and everybody here was family to me," he told WGN.  1413

ALPINE, Calif., (KGTV) -- Some residents in Alpine are ramping up their yard work after Governor Gavin Newsom proclaimed a State of Emergency for the Calfornia's most wildfire-prone areas. Alpine residents have a name for yard work. "It's a necessary evil. We have to clear it out," Jonathan Hesse said. 10News met Hesse as he and his son Ben were raking brush and chainsawing a dead tree on their front yard. "The drought, they [the trees] couldn't handle it anymore. So they died," Hesse said, pointing at the row of what used to be lush trees. He said the time had come to chop them down because he was sure they would ignite his entire 2.5-acre property. In the last two decades, the Hesse's have had three close calls. Their last evacuation was the 2018 West Fire. Luckily, they survived, as did their home. But they are not taking chances. "This year, there's a lot of weeds, and that's going to be tough to keep up with," Hesse said. Luckily, he has a helpful son and a sturdy tractor to help with the clean-up process. They will eventually put their large pile of dead logs and branches through a wood chipper to make mulch. Thanks to the work they did today, the flammability of their home is much lower than it was yesterday. "That's one thing we want to do. We want to make sure it doesn't get out of control," Hesse said. This week, CalFire-San Diego posted a video to remind residents to clear up brush and create defensible space.For more information, click here. 1487

Across the United States, at least six children between the ages of 6 to 14 were shot and killed during the Fourth of July weekend.Communities in California, Washington D.C., Alabama, Illinois, and Georgia are reeling as they mourn the passing of Secoriea Turner, Royta De'Marco Giles, Davon McNeal, Natalia Wallace, a 14-year-old in Chicago, and a 6-year-old in San Francisco, who died by gun violence.Secoriea Turner, 8, Atlanta, GeorgiaAtlanta police say Secoriea Turner was in a car whose driver tried to get through an illegal barricade placed near Wendy's restaurant where Rayshard Brooks was shot and killed back in June when at least two people who opened fire on the car she was riding in.A ,000 reward has been offered in any information in her case. Mayor Keisha Lance Bottoms said in a press conference that "enough is enough." 850

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
