The University of Arizona and Boeing joined forces to find disinfectants that will kill COVID-19 and help make air travel safer. The project known as the Confident Travel Initiative is designed to test out cleaning solutions that can destroy the Coronavirus. Arizona microbiology professor Dr. Charles Gerba, who is known as "Dr. Germ," says he’s been working with Boeing since the summer to test cleaning products as part of the initiative to make flying as safe as possible during the pandemic and beyond.“It's really innovative to try to get a coating that will be antiviral," he said. "I think it’s the next step in hygiene and disinfection adding another barrier between when they clean and regularly disinfect aircraft. We’re looking at coatings. And anytime the virus lands on it would kill it, so you don’t have to keep disinfecting all the time."The team conducted laboratory testing by using a virus called MS2 on surfaces inside of an unoccupied plane. The virus has similar characteristics to the virus that causes COVID-19.“It would protect you from when they disinfect it or clean the aircraft. In case the virus lands again on a surface in the aircraft. We’ve been evaluating the overhead bins, the seats, the trays, the handles,” Gerba said.Cleaning solutions and ultraviolet wands were also used throughout the plane and according to Boeing, the results show that antimicrobial coatings were effective for extended periods of time and won’t be harmful to passengers. While Gerba didn’t share the names of the disinfectants, he did say the products can potentially be used on public transportation and other high traffic areas.“We actually did some of the work in the aircraft going in and contaminating certain areas like the tray in the aircraft the overhead bin and then evaluating the disinfectants to show they could kill the virus," Gerba said. "I see this new technology of self-disinfecting surfaces will revolutionize public places in cleanliness, cars, and buses you name it. These are products already on the market and they are new innovative products where you can put down a coating and it will last for hours, weeks, or maybe even months."The research project is expected to be done with other viruses by the end of the year and airplane cleanings will be done between flights.“It all has a big benefit I think it's going to add that extra barrier to me it’s the next generation of infection control and the spread of disease,” Gerba said.This story was first reported by Shawndrea Thomas at KGUN Tucson, Arizona. 2552

The US believes that Ibrahim al-Asiri, a master al Qaeda bombmaker, is dead.The Saudi Arabian native was the mastermind behind the "underwear bomb" attempt to detonate a flight above the skies of Detroit on Christmas Day in 2009.A senior US official expressed "confidence that he was killed."Two US officials told CNN al-Asiri was killed by a CIA drone last year. The CIA is not commenting on his fate.CNN reported last week that al-Asiri may have been killed in Yemen last year, according to a UN team that tracks terrorist groups.Counterterrorism analysts say there should be significant skepticism over al-Asiri's possible demise for one major reason: His group, al Qaeda in the Arabian Peninsula, has not released any statement acknowledging his death, nor a eulogy celebrating his martyrdom.Al-Asiri is widely credited with perfecting miniaturized bombs with little or no metal content that could make it past some airport security screening. That ability made him a direct threat to the US, and some of his plots had come close to reaching their targets in the US.In addition to the "underwear bomb" attempt, al-Asiri was behind the so-called "printer bomb" plot. That plan saw him send explosive devices inside printers to the US. The two packages were being shipped from Yemen through Dubai and the UK in October 2010.Both were addressed to synagogues in Chicago.Al-Asiri appeared to have taken on a more public-facing role within al Qaeda in the Arabian Peninsula in recent years, including purportedly recording a speech the group released in 2016.The most recent public statement attributed to him was a written speech released by the group on September 12, 2017, to coincide with the 16th anniversary of the 9/11 terrorist attacks. The speech promised an ongoing war against the United States.CNN cannot independently verify he authored these statements.Few expect al-Asiri's expertise to die with him. Officials believe he trained a number of apprentices. And since 2014, US officials have been concerned that bomb-making expertise built up by al Qaeda in the Arabian Peninsula has migrated to other groups, including al Qaeda operatives in Syria.Meanwhile, ISIS is among the terrorist groups that have worked to develop laptop bombs, prompting large electronics to be temporarily banned in the cabin on certain flights to the United States and the UK from the Middle East last year. 2414

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 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 Supreme Court is siding with Republicans to prevent Wisconsin from counting mailed ballots that are received after Election Day. In a 5-3 order, the justices on Monday refused to reinstate a lower court order that called for mailed ballots to be counted if they are received up to six days after the election. A federal appeals court had already put that order on hold. The three liberal justices dissented from the order issued just before the Senate started voting on Amy Coney Barrett’s Supreme Court nomination. Democrats argued that the flood of absentee ballots and other challenges posed by the coronavirus pandemic makes it necessary to extend the deadline. 677
