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

Asked whether President Donald Trump had ever used the N-word, White House press secretary Sarah Sanders would not definitively say, instead referring reporters to a tweet."The President addressed that question directly," she said, adding, "I've never heard him use that term or anything similar."The question comes as former aide Omarosa Manigault Newman has claimed there's a tape of Trump using the racial epithet on the set of his NBC reality show "The Apprentice" -- though there is no evidence such a tape exists.Trump tweeted Monday night: "I don't have that word in my vocabulary, and never have."Pressed specifically on whether any recording of the President using the racial epithet exists, Sanders said: "I can't guarantee anything, but I can tell you that the President addressed this question directly."She maintained that Trump is someone who is "fighting for all Americans," and that his policies are helpful "particularly for African-Americans," citing African-American unemployment statistics.Sanders also claimed Tuesday that Trump's description of his former aide as a "dog" had "nothing to do with race and everything to do with the President calling out someone's lack of integrity."The "dog" comment was one of many insults the President has used to describe prominent African-Americans, but Sanders insisted Trump insults people of other races as well."The President's an equal opportunity person that calls things like he sees it," she said. "He fights fire with fire." 1501

As the COVID-19 vaccine makes its way across the country and into the hands of those who need it most, many nursing homes and senior communities are anxiously waiting as they are the most vulnerable.“I’m a true Okie from Muskogee, Oklahoma,” says 80-year-old Donna. After 46 years, she and her 83-year-old husband Art made the decision to leave the countryside and move into a senior community. They chose one of the 26 Arrow Senior Living communities that are housed around the Midwest. Things were great until the pandemic hit.“Since we live on the independent side, we do our own things. Until this COVID hit, we came and went as we wanted to,”she said.Their way of living is now completely different. No visits with their three sons. No extracurricular activities. They're diligent about masks and about the proper public health measures to prevent the virus.“It's a big concern, we know this is a killer,” Donna said. “Some get a light case and some are asymptomatic and you never who’s going to get the serious case.”Which is why she's anxiously waiting for the vaccine. She remembers when the polio vaccine came out and said it was wonderful."I don’t remember people questioning it, being afraid of having it so much then as some people today but I don’t know why they’d even question it with the horrible pandemic we’ve been having,” Donna said.Stephanie Harris, CEO of Arrow Senior Living said “absolutely” when asked if she would get the vaccine. Harris says her employees will get it too. In all, nearly 4,000 people between residents and staff will need to be vaccinated.“We have been blown away at how overwhelming the response has been by our resident group, over 90% of our residents, when we surveyed them, said ‘yes’ to vaccination,” says Harris.They're not first in line, but they're not far off. They have clinics scheduled for late December, and they're excited.“I’m tired of being cooped up and taking extraordinary precautions to ensure that I could be here in this seat to support our larger operation and I want to be able to get on with some sense of normal,” Harris said.Harris added this recent surge has been brutal and it's taking an emotional toll on everyone.Holiday gatherings have been canceled, important events missed during a time when grandparents should be spending with grandkids. It's caused Arrow Senior Living to take extraordinary precautions, deploying things like mask detection technology to determine whether face coverings are being utilized. There's not one community in their network that hasn't been touched by COVID-19.“This is going to be a strange Christmas, we’re accepting it,” Donna said. “We have three sons but they’re all doing their thing. They didn’t feel like it was safe to travel and we’ll be having Christmas here.” 2789
