As states across the country grapple with an increase in coronavirus cases and a huge demand for tests, many businesses are looking for other ways to get more mileage out of their supply chain.Like with anything else, supply and demand is a constant struggle. In this unprecedented era, the demand for things like coronavirus tests is so large that public health departments don't have a choice but to figure out ways to make our supplies last. Several states are examining pooled testing. California's Public Health Department says it's to "better leverage testing resources."Pooling is something that blood banks have used for decades to keep their blood supply safe. Dr. Claudia Cohn is the Chief Medical Officer of the AABB, formerly known as the American Association of Blood Banks.“If you have 100 people that need to be tested and if you test each of them, you’ll do 100 tests. If you find that your test is sensitive enough that you can pool together 20 samples at the same time, instead of having 100 tests, you can have five pools of 20,” Dr. Cohn said.Now, if one of those five pools is positive, then Dr. Cohn says, "You’ll need to break it out and test each of those separately. So, let’s say you have one positive person in a pool of 100 people, you either do 100 tests and find one positive or you do five pools of 20, four of those pools will be negative, so you’ve done 4 pools and covered 80 people."The test works by taking a tiny sample from each person who was tested.“When you take a swab from everyone’s nose, you isolate the DNA from that swab,” Dr. Cohn said about the PCR test, which is generally a nose swab. “It’s not a lot, it’s a small amount but it’s enough. Because these tests are very, very sensitive.”Those tests are so sensitive, and they have to be, that pooling can really only work if the test can handle, as in detect, multiple samples at once. The FDA mandates that.“The FDA is quite demanding as they should be in terms of making sure tests work well and are safe,” Dr. Cohn said.And Dr. Cohn says, pooling wouldn't work in an area where there's a large outbreak, which means a large number of people would test positive regardless of pooling. In the blood world, this strategy has been perfected.“You are taking 100 samples and taking a drop from each sample and putting it together,” Dr. Cohn said. “You are testing every single person who comes through. In the blood world safety is before everything."Blood banks test for HIV, Hepatitis C and B and well as COVID-19 antibodies, according to the American Red Cross. And, as this pandemic moves through our communities, Dr. Cohn says our blood supply needs to remain strong.“After that initial spike, it went down again and that was okay because elective surgery had been canceled, so the demand for blood had gone down as well so for a while we were at a good balance of demand and supply. But then elective surgeries opened up and hospitals went back to full service and we’re in a shortage again,” Dr. Cohn said. 3017

Authorities in New York have closed a preschool in Harlem after a 3-year-old boy died from what family members say was an allergic reaction.According to a verified GoFundMe page set up by a family friend, Elijah Silvera went into anaphylactic shock on Friday, November 3rd after he was given a grilled cheese sandwich by an adult at the school, "despite them knowing and having documented that he has a severe allergy to dairy." The toddler was taken to Harlem Hospital where he died, the website said.The New York City Health Department said in a statement that it had temporarily closed the school, the Center for Family Services, which is a part of the city's universal pre-K program. The department is "continuing to aggressively investigate what happened and whether the facility could have done something differently to prevent this tragedy," the statement said."There is nothing more important than the safety of our children and we are deeply saddened by this tragedy. We will get to the bottom of what happened here," the department said.The Center for Family Services did not respond to multiple CNN calls for comment."The safety and well-being of children in our EarlyLearn centers is critically important," NYC Adminstration for Children's Services tweeted Thursday. "Following a critical incident at any of our EarlyLearn centers, we place the provider on heightened monitoring or a corrective action status."A health official, who asked not to be named, told CNN the Center for Family Services has been closed for "failing to follow its written safety plan and failing to adequately supervise a child, in violation of the Health Code."Officials say the most recent inspection of the school occurred on September 21, 2017. No violations were cited."The tragic loss of Elijah Silvera did not have to happen," the child's family said in a statement through their attorney, Nicole Weiser. "The failure to follow long established protocols by both the pre-school and by Harlem Hospital resulted in this monumental loss for the Silvera family."According to the GoFund Me page, a portion of the funds raised will be donated to "FARE" Food Allergy Research & Education, "the largest nonprofit working on behalf of the food allergy community. "As of Thursday evening, the page has received ,510 of its k goal. 2332

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

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

As President Donald Trump’s chances of re-election are sagging on Wednesday, the president declared himself a winner in the presidential election on Wednesday despite projections showing he is trailing Joe Biden in the Electoral College.As of Wednesday evening, Biden holds a 248-214 advantage in the Electoral College.
