As we shield ourselves in any way possible from the novel coronavirus, there are some parts of the country handling social distancing better than others.“This is a public health problem; it’s not a private health problem,” explained Dr. Bhaskar Chakravorti, who leads the Fletcher Institute for Business at Tufts University. “If I get sick, I could make three other people sick.”Over the past few months, Dr. Chakravorti and his colleagues have been analyzing mobility data from across the country.What did he and his team discover?The top three states who were practicing social distancing the most were New York, New Jersey and Massachusetts. Nebraska, South Dakota, Arizona were among the worst when it came to practicing social-distancing procedures. Dr. Chakravorti says that has led to higher contagion rates in those areas.“In this post-pandemic moment, each state is going in somewhat a different direction as far as how it's managing the pandemic,” he added.In bigger cities with higher rates of infections, the study found that people responded better to restrictions because they could see the impact the coronavirus was having around them. Dr. Chakravorti hopes public health officials use his findings to make more uniform policies nationwide.“This whole issue of COVID has become a political issue, so even the act of wearing a mask has become a political statement,” he said. “You never want to mix politics with anything. You definitely don’t want to mix it with public health. That’s a dangerous combination.” 1534

Bad news: There is a small chance an asteroid will collide with Earth. The good news: Mankind has more than 115 years to prepare for it. According to a Washington Post report, NASA is preparing for possible tactics to deflect the asteroid Bennu, which will approach Earth Sept. 21, 2135. As of today, NASA rates Bennu's chance of striking Earth at one-in-2,700.The asteroid is roughly 1,600 feet in diameter, and would not be an Earth-ending event if it struck. But that doesn't mean it couldn't cause damage, especially if it struck near a populated area. Bennu is likely dozens of times larger than the object that struck near Chelyabinsk, Russia in 2013, causing hundreds of injuries, and thousands of broken windows. The event caused nearly million in damage to roughly 7,000 buildings. The 2013 event shows that even small objects are capable of causing massive damage. In 2016, NASA launched OSIRIS-REx, which will land on the asteroid and bring back samples. The information gathered could help NASA decide what steps it would take to deflect the asteroid. According to the Washington Post, NASA is working on a plan called the Hypervelocity Asteroid Mitigation Mission for Emergency Response, or HAMMER. NASA's HAMMER plan could involve using a nine-ton bulk impactor to push Bennu out of Earth's path. Another idea would be straight out of the movie "Armageddon," using a nuclear-type device to move the asteroid. A NASA engineer involved in the study told the Washington Post all of these ideas are theoretical. “We’re doing these design studies to prepare ourselves, so if we do find a threatening object, we’re better prepared to deal with it,” Brent W. Barbee, NASA engineer, told the Post.To read the Washington Post's full report, click here.  1855

Bad actors online are gearing up for the election.Experts with the cyber security company Check Point are warning that before, during and after Election Day, you could see clever campaigns to cast doubt on accuracy and results of the election.“You know, in contrast to previous elections, where it's been about very targeted looking to gain access to things, we really think from what we've seen from a research perspective is that it will be a larger attempt to create disruption versus anything else,” said Mark Ostrowski with Check Point.The software company is warning of a flood of memes on social media. They say the goal is to get so many going and people sharing them that algorithms and admins won’t be able to keep up with taking them down.The goal is to spread false information or create disruption.Check Point is sounding the alarm so people can educate themselves and not spread these.“We even have some of our researchers and instant response folks have even seen some evidence or some type of reliable information where regardless of who wins, there are certain mean themes that are going to be saying, hey, this, this is who the victor is regardless of what the actual results are to again to create this indecision To create this division,” said Ostrowski.Obviously, you can simply report an image on any social media site and only share credible sources on election information. 1405

  

At age 106, Sen. John McCain's Roberta McCain mother will be in attendance at the late senator's funeral this Saturday in Washington, D.C., and his burial service in Maryland, the Associated Press reported. Roberta McCain has outlived the son she called "Johnny," as the U.S. Senator from Arizona died on Saturday at the age of 81. Sen. McCain will be lain in state at the U.S. Capitol on Friday before his final services on Saturday. Roberta McCain, at age 96, was active on the campaign trail for her son during his presidential bid. She also made a number of appearances on television, including one controversial spot on MSNBC's Hardball, where she went after fellow GOP presidential hopeful Mitt Romney. Roberta McCain had an identical twin sister, Rowena Wright, who died at the age of 99 in 2011.  842

  

At least 71 people were killed and 325 others wounded in rebel-held Eastern Ghouta after the Syrian government carried out a series of airstrikes and artillery bombardments, the UK-based Syrian Observatory for Human Rights said Monday.Sixty-two of the victims were civilians, including nine children and five women. Nine militants were killed, the group said of the attacks near Damascus over a 24-hour period.CNN could not independently verify the claim.The Eastern Ghouta area has been surrounded by Syrian forces for more than four years, with the siege intensifying last May when government forces conducted a large-scale offensive.It was supposed to be one of the "de-escalation zones," according to the peace agreement struck by Russia, Turkey and Iran in May 2017.About 400,000 Syrians have been killed since the conflict erupted in 2011, according to the United Nations. As many as 5.4 million Syrians have left their country, the UN Refugee Agency said, and 6.1 million are displaced from their homes but still inside Syria. The UNHCR High Commissioner, Filippo Grandi, calls the situation in Syria "the biggest humanitarian and refugee crisis of our time."The-CNN-Wire? & ? 2018 Cable News Network, Inc., a Time Warner Company.
