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 University of Washington’s Institute for Health Metrics and Evaluation now projects that 67,000 American lives would be saved between now and December 1 by near universal wearing of masks.The IHME released the updated model on Thursday. As part of the update, the IHME said that four states, Arizona, Florida, Mississippi, and South Carolina, have hit an important metric of a daily death rate of eight per one million residents, and that those states should re-impose statewide closures of non-essential businesses.The IHME’s coronavirus projections have been frequently cited in the past by the White House’s coronavirus task force. The group uses state data along with other metrics to create projections on the number of coronavirus-related deaths throughout the US.The model projects with inconsistent use of masks, the US death toll for the coronavirus will be up to 295,000 by December 1, an increase from the current figure of 158,000, per Johns Hopkins University data. The IHME’s projections drops considerably to 228,000 if masks are worn universally outside of the home.IHME director Dr. Christopher Murray said at a news conference on Thursday that mask wearing mandates work, but communities also respond when they see cases are spreading.“People do respond to the circumstances in their community,” Murray said. “Mandates have an important effect.”One thing the model does not take into account is the use of therapeutics of a possible vaccine. Murray said that the IHME is closely monitoring the effectiveness of two potential therapeutics – remdesivir and dexamethasone – and may adjust future models as more is learned about those drugs.The model expects the number of coronavirus-related deaths to ebb and flow into the fall, but begin to increase by November. "November is a month we expect the spread to increase due to seasonality," Murray said. We are expecting considerable daily deaths. That pushes up our projections."“We expect it rise later in the fall,” Murray added.One cause for concern comes at the end of November when families begin to travel for holidays such as Thanksgiving.Murray said that while mask-wearing is not necessary when around family members of the same household, he said mask-wearing may be necessary for holiday gatherings. Murray said his family is taking the recommendation one step further, and is simply not gathering with extended relatives this fall.What’s built into the IHME’s projection is that a number of states will need to implement stricter closures in order to slow the spread. As part of the IHME’s recommendation, states implement closures of non-essential businesses when there is a threshold of eight deaths a day per million. Also part of the modeling is based on 50% of schools being closed in each state for the upcoming year. Murray said with many schools opening or implementing hybrid models, more will be learned in the coming weeks on how easily the virus spreads within schools.Recent measures in Arizona, California, Florida, and Texas has allowed a small decline in cases, but deaths in those states have not dropped off, according to Murray.“We have been seeing cases peaking and hospitalizations peaking and deaths not quite yet peaking, but we expect them to peak in the near future but we don’t expect a sharp decline," Murray said.To see a state-by-state breakdown of the IHME’s projections, click here. 3403

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

  

The United States is demanding that all United Nations sanctions be reimposed against Iran, a move that follows America’s embarrassing defeat to extend an arms embargo against Tehran. President Donald Trump says Secretary of State Mike Pompeo will travel to New York on Thursday to notify the Security Council president that the U.S. is invoking the so-called “snapback” mechanism in the council’s resolution that endorsed the 2015 Iran nuclear deal. Other nations claim the U.S. has no standing to make the move because the Trump administration pulled the U.S. out of the Iran nuclear deal two years ago."Today, I am directing the Secretary of State Mike Pompeo to notify the UN Security Council that the United States intends to restore virtually all of the previously suspended United Nations sanctions on Iran," Trump said. 836
