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

AUSTIN, Texas — A Texas man is making a statement by writing the names of 1,400 Black Americans who have died at the hands of police in the United States on his car.20-year-old Jeremiah Hindberg says he used a database to research Black Americans who have died at the hands of police in the U.S. and came up with 1,400 names.He wrote each one on his vehicle with a silver sharpie.Hindberg says he is using his car in hopes to start a conversation on what the Black Lives Matter movement means to him."A lot of sadness. I cried in my garage for hours," Hindberg said.It took several days to write the names, with George Floyd and Breonna Taylor on the hood."This is my representation of BLM," Hindberg said. "Some group of people that's being treated unfairly, and that should be fixed."Hindberg says the violence he and his father witnessed during the protests in Austin back in late May moved him more than anything he's ever experienced.The two served as medics and helped bring aid to injured protesters.He says many protesters were hurt by "less lethal" rounds fired by police, including his father who was shot in the arm and is still recovering from nerve damage today."It changed who my dad was fundamentally as a person," Hindberg saidAs a food delivery driver, Hindberg says reaction to the car ranges from being cursed out in grocery store parking lots to more warm moments of gratitude."She just looked at me in the eye, and said thank you so much she started to tear up and cry," Hindberg said, describing moments that remind him why he did this to his car. "Somebody knows that they're cared for. They're not just another number, they're not just another person."This story was originally published by KXXV in Waco, Texas. 1743

ATLANTA, Ga. – U.S. Rep. John Lewis has died at the age of 80.The congressman and civil rights icon had been undergoing treatment in his battle with stage 4 pancreatic cancer.Lewis, a Democrat, served 17 terms in the House of Representatives, representing Georgia’s 5th congressional district since 1987.House Speaker Nancy Pelosi confirmed Lewis’ death after several reports Friday night, saying “Today, America mourns the loss of one of the greatest heroes of American history: Congressman John Lewis, the Conscience of the Congress.”Along with Martin Luther King Jr., Lewis was one of the “Big Six” civil rights activists who organized the March on Washington in 1963. Lewis was perhaps best known for leading hundreds of protesters in the Bloody Sunday march across the Edmund Pettus Bridge in Selma, Alabama in 1965.“John Lewis was a titan of the civil rights movement whose goodness, faith and bravery transformed our nation – from the determination with which he met discrimination at lunch counters and on Freedom Rides, to the courage he showed as a young man facing down violence and death on Edmund Pettus Bridge, to the moral leadership he brought to the Congress for more than 30 years," said Pelosi in a statement. In Congress, Lewis was respected by members on both sides of the aisle as he fought for freedom and justice for all.“In the halls of the Capitol, he was fearless in his pursuit of a more perfect union, whether through his Voter Empowerment Act to defend the ballot, his leadership on the Equality Act to end discrimination against LGBTQ Americans or his work as a Senior Member of the Ways and Means Committee to ensure that we invest in what we value as a nation," said Pelosi.Throughout his life Lewis received numerous awards for his work and in 2011, President Barack Obama awarded Lewis the Medal of Freedom, the highest civilian honor in the U.S.“Generations from now, when parents teach their children what is meant by courage, the story of John Lewis will come to mind, an American who knew that change could not wait for some other person or some other time; whose life is a lesson in the fierce urgency of now,” said Obama as he presented the medal. 2196

AZUSA (CNS) - A homeless man suspected of intentionally starting the Ranch 2 Fire in Azusa surrendered to authorities Sunday, while firefighters endured another day battling the blaze amid scorching temperatures.The fire, which grew to 2,256 acres overnight, was just 7% contained Sunday.The man suspected of intentionally starting the fire, 36-year-old Osmin Palencia, was in custody at the Azusa Police Department jail. Police did not release further information except to say that the investigation was still active, and urged anyone with information about the fire's origin to call 626- 812-3200.On Saturday, police said Palencia was believed to have a connection to the Monrovia area and possibly a woman known as "Madonna Ortiz." They added he is violent and has multiple active arrest warrants.Palencia also had four misdemeanor arrests over the last two years, three by Azusa police and one by sheriff's deputies, according to jail records.Palencia's last known residence is an encampment in the Azusa Canyon Riverbed, police said.A witness who lives in a riverbed near Mountain Cove told NBC4 an argument between two homeless men sparked the fire."There were two gentlemen in the back (of a homeless encampment) fighting and they were arguing over a bike and one guy said he'd burn the other guy out, and things got escalated to where the fire started," evacuee Jimmy Pockets told the station. "Ran over to try to put it out but it just took off so quick."Firefighters said high temperatures, slope, aspect and winds "came into alignment" overnight, causing the fire to became very active at the bottom of Roberts Canyon and move upslope amid dense mixed-chaparral fuels, sending a large pyrocumulus cloud formation into the sky that could be seen throughout much of the Southland.Firefighting aircraft were grounded for the night Saturday due to a drone flying in the fire area that was spotted at 6 p.m. Officials noted that there is a temporary flight restriction in the vicinity, and flying drones there is illegal.All earlier evacuations orders have been lifted, but the following road closures remained in effect:San Gabriel Canyon Road/Highway 39: closed at Northbound Hwy 39 at Sierra Madre Avenue (southbound Highway 39 is closed at East Fork Road)Glendora Mountain Road: closed from Big Dalton to East ForkGlendora Ridge Road: closed from Glendora Mountain Road to Mt. Baldy RoadSanta Anita Canyon Road: closed from Arno Drive to Chantry Flats RoadThe Angeles National Forest changed its Forest Fire Danger Level from very high to extreme, and moved into full fire restrictions including prohibiting campfires in developed sites. Cooking stoves, lanterns and similar devices that use propane, white gas or similar fuels were prohibited.The Ranch 2 Fire was reported about 2:45 p.m. Thursday near North San Gabriel Canyon Road and North Ranch Road, according to the Azusa Police Department and Los Angeles County Fire Department, which called in a second- alarm response.The number of personnel committed to fighting the blaze had reached 286 Sunday. 3076

Authorities in India have decided to hold off retrieving the body of the American national feared killed on North Sentinel Island amid concerns about a possible confrontation with the tribe that lives there.John Allen Chau is believed to have been killed by Sentinelese tribespeople after he visited their island home in the Andaman and Nicobar archipelago in November, breaching local laws strictly prohibiting contact with the isolated people.Indian police say Chau found local fishermen who agreed to take him near the island, before using a canoe the rest of the way. Days later, the fishermen -- who have since been arrested for facilitating his trip -- say they saw the tribespeople dragging his body around the island."We want to avoid direct confrontation with the tribespeople," Dependra Pathak, director general of police of the Andaman and Nicobar islands, told CNN when asked about the latest efforts to retrieve Chau's body. "We do not want to go there and create an unhappy situation."The decision to avoid a direct confrontation with the isolated tribe came after a series of meetings and reconnaissance trips made by the officials. Anthropologists and tribal experts were also consulted.By Sunday, authorities had mapped out the area with the help of the fishermen and observed several members of the tribe walking around the area where eyewitnesses claim to have seen Chau's body dragged and buried.However, despite ruling out any immediate attempts to land on the island, local police would not categorically rule out retrieving the body at a future date. "We are working on it. We'll firm up a plan very soon," said Pathak. 1650
