As the death toll from the Camp Fire rose to 63 people, rescue workers searching for human remains in the wreckage hope that hundreds of people who are still unaccounted for after the blaze are still alive.After going through a week of 911 calls, authorities announced Thursday they are looking into reports of 631 people who are possibly missing."You have to understand, this is a dynamic list," Butte County Sheriff and Coroner Kory Honea said Thursday evening. "Some days might be less people, some days might be more people, but my hope at the end of the day, we have accounted for everybody. "Photos: Wildfires devastation in CaliforniaA week after two major wildfires sparked at both ends of the Golden State, the total death toll has increased to 66, fire officials said.The Camp Fire -- now the deadliest and most destructive wildfire in the state -- has left 63 people dead, destroyed about 9,700 homes and scorched 141,000 acres. By Thursday night, it was 40% contained.Hundreds of deputies, National Guard troops and coroners are sifting through leveled homes and mangled cars for human remains."They are going to be searching vehicles that have been burned. They'll be searching residences that have been burned. Checking around the residences ... our mission is to find the victims from this fire, recover them and get them identified and notify the families to give them some answers," Butte County Sheriff's Investigations Sgt. Steve Collins said.President Donald Trump is expected to visit the region Saturday as firefighters continue battling the blaze. 1578

As scientists learn more about COVID-19, they are realizing that how people react to the virus could be based on the body's response to viruses like common colds.Meharry Medical College President Dr. James Hildreth says some studies are showing some individuals have T-cell responses to COVID-19 even though they never been exposed to it.He is talking about recent research revealing that some people may have immunity defenders called T-cells which could determine how their body reacts to COVID-19.According to the CDC, when the body fights an infection, the immune system remembers what it learned about how to protect the body against that disease.The body will retain a few specific T-cells known as memory cells - that will alert and help the immune system identify and produce antibodies to attack the foreign germ if it enters the body again."Viruses that look alike can sometimes elicit the same kinds of immune responses," said Hildreth.Hildreth says there are six strains of coronavirus that affect humans going back to the 1960s and some result in seasonal common colds.He says if you were infected with one of these viruses in the past it can determine the severity of the toll COVID-19 would take on your body now."There’s the possibility that a response to one of them gives you a partial to another because they have genetic similarities," said Hildreth.Hildreth says this doesn't mean a person has complete immunity to COVID-19."There’s strong evidence that you may not be immune to the virus, but you’ll have an immune response that recognizes SARS partially just because those two viruses look so much alike."Hildreth says this can help with treatments and even vaccinesThis story was originally reported by Kelsey Gibbs at WTVF. 1756

As wildfires rage across the western part of the country, firefighters are doing their best to contain the flames and prevent further devastation. Most of the fires are burning in areas that haven't seen a wildfire in a long time, making the loss of life and land even worse."It's been difficult. This is becoming all too common. Another record-breaking, severe, unprecedented fire season here in Colorado. And this was the largest forest fire in the White River National Forest history," said Forest Supervisor Scott Fitzwilliams, speaking about the Grizzley Creek Fire. Fitzwilliams says not all wildfires cause complete destruction. In fact, many provide some crucial ecological benefits. Take the big horn sheep who live in the forest. "Their defense mechanism is those big eyes on the sides of their heads so they can see predators coming. And so, they will abandon a habitat when there's too many trees and too much brush and so in many areas of the canyon, this fire improved big horn sheep habitat," said Fitzwilliams.The Grizzly Creek Fire also burned the top of a canyon, helping the habitat for elk and deer. A silver lining to the Grizzley Creek Fire, which also charred creeks that provide drinking water for an entire town in Colorado and was unexpectedly slowed by an early snowfall in the area.At Sequoia and Kings Canyon National Parks in Central California, fire officials conduct what they call "prescribed burns.""A prescribed burn is literally us giving a prescription to the forest," said Mike Theune, Fire Information Officer for Sequoia and Kings Canyon National Parks. Prescribed burns are slow and steady, clear out unnecessary brush and naturally revitalize a forest, he says.Theune and Fitzwilliams say, for more than 80 years, fire services across the country used to put out any and all fires, even if they occurred naturally, such as from lightning."[In the] early 1900s when forest service came into view and smokey bear and we thought we needed to put out all the fires and we did. And we did a great job of it and Smokey Bear was the best spokesperson we could ever ask for but what that did is significantly change the landscape as far as the density of vegetation," said Fitzwilliams."We need to restore that ecosystem to what those natural levels are and one of the ways we can do it is through a very measured and very managed scientifically based approach to prescribed burning," said Theune.Theune says not all national forests in the country need prescribed burns as there are some states that deal with too many forest fires. National parks and forests officials say it's important to evaluate each individual ecosystem's needs in order to preserve their beauty for years to come. 2730

Attorney General Jeff Sessions ordered a review Friday into how the Justice Department and FBI respond to indications of potential violence after the bureau said it failed to act on a tip about the shooter in the Parkland, Florida, school massacre.A person close to Nikolas Cruz, the confessed shooter, contacted the FBI on January 5 to report concerns about him, the FBI said in a statement Friday. But the bureau did not appropriately follow established protocols in following up on the tip."The information was not provided to the Miami Field Office, and no further investigation was conducted at that time," the statement said.The stunning admission -- which prompted Florida Gov. Rick Scott to call on FBI Director Christopher Wray to resign -- is sure to raise further questions about whether the FBI could have prevented the shooting at Marjory Stoneman Douglas High School, which left 17 dead.  915

As we're all focused on the current rollout of the COVID-19 vaccine, a technology known as thin-film freezing is getting a lot of attention. It's groundbreaking and could change the way we administer drugs or use medicine in general.You've probably heard about the need to keep the COVID-19 vaccine cold. It has to be so cold, in fact, that the shipment and transport are challenging. Well, what if that vaccine could be turned into powder?“What we’ve most recently been working on is the elimination of cold chain by storing as a powder, a dry powder where the drug is much more stable than if it was stored as a liquid or as a frozen liquid,” said co-inventor Dr. Robert Williams.Williams said it would eliminate the need for extreme cold storage and transport. The technology isn't new. He got a research grant and came up with it about 15 years ago.Williams, who is also a pharmacy professor at the University of Texas in Austin, said they were working on the technology and its multiple uses when the pandemic hit. And all of a sudden, they got a lot of attention.“We have published over 70 papers on the technology and using it for different products- it’s quite a mature process," Williams said. "We developed it because with other vaccines, the majority of the vaccine cost is in wastage because of this cold chain issue, so we published several key papers where we showed our thin-film freezing technology would protect vaccines - and you wouldn’t need cold chain storage.”Glenn Mattes, President, and CEO of TFF Pharmaceuticals added that the powders can be converted to topical preparations and they are currently working with the US Army to take some of the preparations and would then administer them directly through the eye.TFF is launching thin-film freezing into development through the FDA process. “I use the term ubiquitous because it is and disruptive because it is,” Mattes said. He added that they've explored their technology in the cannabinoid realm. But, as for the COVID vaccine, they're aiming for a second-generation usage.“To truly eradicate the pandemic, you have to have a global response," Mattes said. "The companies we’ve been speaking to certainly recognize the broad utilization of the technology but the application to the developing world, rural area, remote areas, where you can take a powder and inhale it or take the powder and reconstitute it has tremendous potential."Experts say it is only just the beginning as they launch their technology into a new world. 2511
