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

Australian scientists are searching for the remnants of a meteor which burned spectacularly across the sky in Perth Tuesday night.The unusual phenomenon was caught on camera by multiple spectators, and described as a "fireball" on social media.Curtin University professor Phil Bland told CNN it was "almost certainly" a chunk of asteroid coming through the atmosphere, an event which he said occurs only a couple of times a year. 437

BAKERSFIELD, Calif. — California Gov. Gavin Newsom has again denied parole for a member of the infamous "Mason family" who is serving time for a murder committed 50 years ago.Newsom blocked the release of 71-year-old Leslie Van Houten from prison Friday, despite a recommendation from the California parole board that she be freed.It's the fourth time in four years that Newsom has blocked Van Houten's release from prison. Newsom said in his Friday decision that she still poses a danger if released.Van Houten is serving a life sentence for helping Manson and others kill a Los Angeles couple in 1969. She was 19 years old at the time.Van Houten's attorney has said that she will appeal.This story was originally published by Tori Cooper on KERO in Bakersfield, California. 783

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

Australian researchers have developed new technology that allows them for the first time to film a deep-sea swimming sea cucumber.For the time being, they're calling the creature a "Headless Chicken Monster." The name sounds like something a child would name their imaginary friend, but it's pretty accurate once you take a look at the headless blob. The strange sea cucumber was discovered using an underwater camera system in the Southern Ocean off the coast of East Antarctica. The high-tech camera is normally used for commercial long-line fishing, but in this situation, it worked quite nicely."We needed something that could be thrown from the side of a boat, and would continue operating reliably under extreme pressure in the pitch black for long periods of time," said Australian Antarctic Division program leader Dr. Dirk Welsford. "The cameras are providing important information about areas of sea floor that can withstand this type of fishing, and sensitive areas that should be avoided."The large area off the coast of East Antarctica, which is covered with cold-water corals and penguin foraging grounds, has been the focus of a bid to create a protection area — known as the Antarctic Conservation Zone.Now, researchers are hoping that the new technology that captured the rare footage can help the creation of that area.The proposal for protection has previously been endorsed by the commission's scientific committee three times, but China and Russia have blocked the proposal each year, according to a report in Naturer. 1592
