Ahead of the election, many social media sites are tightening things up. Many platforms are trying to make sure what you're searching for, what you're seeing and what you're reading is factual.Pick a platform or a search engine and it's not hard to find what you're looking for.“Remember in 2016, no one took social media seriously on either side,” said Jason Mollica, a professor of communications at American University in Washington DC.He teaches digital and social media analytics and public relations. He analyzes just how we communicate. These days, a lot of our conversing is over the internet. As the election inches closer, Mollica and his students are watching and discussing what's happening on social media platforms.“It’s not that much different but the stakes are higher, not from the perspective of voting but as in what these socia lnetworks are trying to do or not do it the wake of what happened in 2016,” Mollica said.Take Facebook for instance. The social site has been under scrutiny and they know it. Mark Zuckerberg posted from his own account about what changes the site is making, including informational posts about voting and how and where to vote. Facebook will block new political ads in the final week before the election, and they say they'll be working with officials to remove misinformation about voting.There are also rules against COVID-19 threats surrounding voting.Twitter is also taking a stand. Mollica says you might see something trending but if there's a problematic post, the original content will likely be pulled.“We’re not gonna allow this content to continue is something is shared by Joe Biden or Donald Trump or any political party,” Mollica said. “They’re going to make sure it’s taken down because they want to mitigate the negative news or the false news that comes out from certain accounts.”Twitter says it has election teams focusing on integrity, and the company is launching initiatives to help users find original sources of information. You'll also be able to report misleading information.“This isn’t censorship,” Mollica said. “This is something where social networks are saying, ‘Look, we understand we’re a news cycle.’ At least from Twitter’s perspective, they share news. They want to be a place where people get news. They’re looking… from a standpoint of you wouldn’t see that on a television station necessarily, why should you see that on twitter?”And Google, the site many turn to to search for anything and everything, has modified its autocomplete policies, removing predictions that could be viewed as claims for or against a specific party. And that is no easy task.“Think of a search giant like google. They can’t pull content off the internet but they can definitely take key words from search results and say we’re not going to show those to people,” Mollica said.Donald McLaughlin, co-founder of the Denver Based CP-Cyper said, it’s not that internet content is missing. Google has just made information harder to find. McLaughlin says, however, it doesn't mean that you can't find it on other search platforms.“Use a different search engine,” McLaughlin said. “There is Bing, DuckDuckGo, a few others that are meant to be less persuasive, less filtered that will give you exactly what you search for versus what they want you to see or what they think you want.”“So, Google trying to mitigate it somehow is a great start but you think about it’s basically putting a small cork in a huge hole and it’s still leaking and you can’t really stop it,” Mollica said.Most experts would agree it’s unfortunate that it has come to this.“We’ve gotten to a place now where misinformation does spread like wildfire on social media. People will sensationalize to get likes to get people to follow them and really doing the research to vet whether something is true or not is very important,” Mollica said.He says that's true whether you're buying a car, or voting. And while the internet giants can only do so much, it’s a big step on the keyboard as we move toward the election. 4053

About 350 newspapers in the United States had editorials Thursday decrying President Donald Trump's description of the media as the "enemy of the people."Here are some of the newspapers blasting Trump's anti-press rhetoric. 231

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

Alabama Republican Senate candidate Roy Moore says he will sue the Washington Post over its report alleging he pursued sexual relationships with teenagers -- including a 14-year-old -- when he was in his 30s."The Washington Post published another attack on my character and reputation because they are desperate to stop my political campaign. These attacks said I was with a minor child and are false and untrue -- and for which they will be sued," Moore said Sunday night during a campaign speech in Huntsville, Alabama.A message left with The Washington Post Monday morning was not immediately returned. 613
