The U.S. has now surpassed 17 million confirmed cases of COVID-19 and has yet again recorded more than 1 million cases of the virus in less than a week, according to a database kept by Johns Hopkins University.The U.S. reached the 16 million case threshold over the weekend. According to the COVID Tracking Project, the country is averaging more than 200,000 new cases of the virus every day, putting it on pace to record 1 million cases every five days.Since Oct. 30, the U.S. has recorded more than 8 million cases of COVID-19 — a number that represents 47% of all cases recorded since the virus reached the U.S. in January. The U.S. is currently in the midst of the most deadly stretch of the pandemic to date. The country surpassed 300,000 deaths linked to the virus on Monday. Since then, nearly 8,000 more people have died of the disease.The COVID Tracking Project reports that the U.S. has averaged more than 2,500 deaths every for the last week — and that number will likely increase in the weeks to come. The COVID Tracking Project also reports that record numbers of Americans are battling the virus in a hospital. The group says more than 113,000 people are currently hospitalized with the virus, leading many health care facilities — particularly those in rural areas — to reach maximum capacity levels.Spikes in COVID-19 typically trail behind spikes in cases and hospitalizations, meaning death totals will likely only increase in the weeks to come. 1481

The US Secret Service said it is reviewing an incident in which an agent blocked a CBS News reporter on Tuesday from questioning Jared Kushner, the President's son-in-law and a senior White House advisor, about the disappearance of Saudi journalist Jamal Khashoggi.In video posted to Twitter by the journalist, Errol Barnett, a US Secret Service agent physically prevented him from questioning Kushner. When Barnett explained that he was a member of the press, the agent replied, "I don't give a damn who you are. There's a time and a place."In a statement provided to CNN, a spokesperson for the US Secret Service said the agency was "aware of the video" posted by Barnett. 682

The Trump administration plans to announce the long-anticipated federal rule officially banning bump stocks in the coming days, according to US officials familiar with the matter.Bump stocks gained national attention last year after a gunman in Las Vegas rigged his weapons with the devices to fire on concertgoers, killing 58 people. President Donald Trump vowed to outlaw the devices soon after the tragedy, and some lawmakers on Capitol Hill urged him to back a permanent legislative fix.But opposition from lawmakers and the National Rifle Association ultimately made a regulatory change the only realistic path forward to accomplishing the President's goal.The devices make it easier to fire rounds from a semi-automatic weapon by harnessing the gun's recoil to "bump" the trigger faster -- an operation that caused officials at the Bureau of Alcohol, Tobacco, Firearms and Explosives during the Obama administration to conclude that it's merely a gun accessory or firearm part, not subject to federal regulation.At Trump's direction, however, the Justice Department submitted a proposed final rule earlier this year that upended the Obama-era interpretation, and concluded that bump-fire stocks, "slide-fire" devices, and devices with certain similar characteristics all fall within the prohibition on machine guns by allowing a "shooter of a semiautomatic firearm to initiate a continuous firing cycle with a single pull of the trigger," and therefore, they are illegal under federal law.Under the new rule, bump stock owners would be required to destroy or surrender the devices to authorities. Members of the public will be given 90 days to turn in or otherwise discard their bump stocks, according to a source familiar with the final rule."Bump stocks turn semiautomatic guns into illegal machine guns. This final rule sends a clear message: Illegal guns have no place in a law-and-order society, and we will continue to vigorously enforce the law to keep these illegal weapons off the street," a senior Justice Department official told CNN Wednesday.Republican lawmakers, who are typically opposed to federal agencies writing regulations to accomplish what Congress hasn't directly legislated, had insisted that the Justice Department and ATF write a new regulation. Whereas some Democrats, such as Sen. Dianne Feinstein of California, have repeatedly cautioned that such a ban would likely result in lawsuits given ATF's earlier interpretation.ATF Acting Director Thomas Brandon acknowledged in a Senate hearing this summer that he has been advised that banning bump fire stocks through executive regulation could lead to court challenges that would delay the implementation of a ban.Trump said last month he told the NRA "bump stocks are gone," but how the group responds to the final rule remains to be seen. A spokesperson for the NRA said in October 2017 that the ATF "should review bump-fire stocks to ensure they comply with federal law," but made clear it opposed the broader gun-control legislation raised by some in Congress.In June, Slide Fire Solutions, the Texas company that invented the bump-fire stock device and was its lead manufacturer, announced on its website that it would stop taking orders for its products and would shut down its website.The company, however, directs buyers to RW Arms, an arms dealer also based in Texas, which appears to be selling the remainder of Slide Fire's inventory. RW Arms was advertising for bump fire stocks made by Slide Fire as recently as this week, when they offered a Cyber Monday sale on the product. Slide Fire has not responded to repeated requests for comment about any potential litigation over a federal rule banning bump stocks.The-CNN-Wire 3725

  

The timelines on your Instagram accounts have probably been flooded recently with women posting black-and-white pictures of themselves.The premise of the viral trend comes as a way for women to support each other with the accompaniment of the hashtag #ChallengeAccepted in their caption.The origins of the first picture used in the trend were traced by Taylor Lorenz of The New York Times. Lorenz found that a journalist in Brazil posted the very first picture in the challenge.There had been reports that the challenge first began in order to bring awareness about femicide in Turkey, but Lorenz spoke to Instagram and tweeted that the hashtag in Turkey and the United States were unrelated. 700

  

The spread of COVID-19 is tough to trace and even tougher to predict, but researchers at Pittsburgh’s Carnegie Mellon University created an early warning system to help protect you from the virusMathematics professor Po-Shen Loh developed an app called NOVID, a contact-tracing app, to help communities see the virus coming before they get infected.On top of creating a brand new app, Loh teaches math to middle-school students online from his own office-turned-broadcast studio. He’s also the national coach for the United States Math Olympiad team that competes around the world.But when the pandemic hit, Loh wanted to take on one more project. “I like things that are supposed to be impossible, that can’t be done,” said Loh. Stopping the spread of the coronavirus seemed to fit the bill.“The problem with COVID is it spreads before you know you have it, that’s what makes COVID different," Loh said. "The only way you can control this disease is in helping people to know whether or not COVID is coming close to them in advance."That’s where the NOVID app can help, said Loh. “Shows the virus coming towards you based on your relationship network, so that you can protect yourselves from others before you actually get infected," Loh explained of the app. "This is in contrast to most other contact tracing apps that are designed to protect others from you."The app shows you positive cases in degrees of separation. A positive case in the first degree would be someone you live with. The second degree could be your coworker or a friend. The third degree would be that person’s spouse or child. Each degree of separation is a possible pathway for you to come in contact with COVID-19.“This thing shows you the virus coming towards you, kind of like a hurricane satellite shows you a hurricane coming towards you,” said Loh.In addition to showing you cases as they pop up around you, the app can track the distance between phones down to the inch.It uses both Bluetooth and ultrasound waves to give you that measurement to make sure you’re safely social distancing.“We don’t know of any other contact-tracing app in the entire world which will tell you, ‘here’s how far away we think the device was,’” said Loh.The safety of your personal information is one of the most important features of this app. It collects data, while you stay completely anonymous.“Many people are distrustful of an app that does contact tracing,” said Loh. “We never ask for your phone number or email."Those who are positive can self-report their case in the app. Loh is also working with cities and counties to integrate NOVID into health departments across the country. He said the health departments would issue a ticket with a number to each person who tests positive for the virus.That person would enter the number into their NOVID app, anonymously reporting the positive case in the community.“If this thing actually caught on, you’d see in all the cities and towns, whether it’s rural or urban, whenever COVID starts to rise up, you’d start to see everyone take caution. Not because anyone forced them to, but because they saw this is what would be useful,” said Loh.To create the powerful community resource Loh is hoping for, he said more people need to know about the app.“Right now, we only respond when the intensive care units are full, and then it’s too late, and people die on the sidewalk. But, what we wish would happen, is that people could see it coming, and then, everyone starts to be careful at the right time. With more traction, we can save more lives,” he said.Loh is hoping he can not only help save lives but help bring back life as we knew it.“The goal of what we’re trying to do is to give people headlights to drive in the dark. Our app is not designed to let other people control you; our app is designed to help you control your life,” said Loh.For more information on NOVID or to download it, click HERE. 3928
