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

As students from across the country prepare to return to classrooms in the middle of a pandemic, a nationwide school nurse shortage has health experts concerned about how well some districts will be able to handle potential outbreaks of COVID-19.Linda Mendonca oversees the National Association of School Nurses. As she thinks about empty classrooms beginning to fill back up with students, she can’t help but be filled with anxiety.“We don’t have a road map for all of this, so when you don’t have a road map, that makes it a little more challenging,” she said.School nurses will be playing a critical role in the reopening of schools. They’re being asked to monitor kids for COVID-19 symptoms and even keep track of absentee rates to spot potential trends. In some cases, school nurses will help local health departments with contact tracing if an outbreak occurs at a school.But a nationwide nurse school nurse shortage puts a lot of that in jeopardy.“In the midst of a pandemic, there should be a nurse in every school, and there’s not,” Mendonca explained.About 25 percent of the nation’s schools will start this year without a school nurse. It’s a startling statistic that has public health officials particularly concerned, in the middle of a pandemic.The average school nurse makes about ,000. There’s also a simple funding problem. School nurses are often the first to get cut when districts need to eliminate positions. The need is so great, that the National Association of School Nurses is advocating for 10,000 new nurses in the next federal stimulus bill.“The school nurse is so important that there needs to be a full-time nurse in school every day at all schools,” said Jenny Gormley, who’s served as a school nurse in Massachusetts for years.Gormley’s hope is that in the face of this pandemic, districts across the country will find ways to support nurses with both PPE and funding.“We all want students back learning, but we want to do it safely,” she added.As parents attempt to send their kids safely back to school, school nurses could be one of the best prescriptions for success. 2114

ASSISI, Italy (AP) — A 15-year-old Italian computer whiz who died of leukemia in 2006 has moved a step closer to possible sainthood with his beatification in the town of Assisi. Carlo Acutis is the youngest contemporary person to be beatified. He follows two Portuguese shepherd children living in the early 1900s who were proclaimed Catholic saints in 2017. Already touted as the “patron saint of the internet,” Acutis created a website to catalog miracles and took care of websites for Catholic organizations. While still in elementary school, Acutis taught himself to code using a university computer science textbook, and then how to edit videos and create animation. The cardinal who beatified him said he used the internet “in service of the Gospel.” 764

  

As students return to school and employees head back to the office all with new safety protocols likely including wearing a mask, a new study from Duke University explores which masks are more effective.Spoiler alert: A fitted N95 mask, usually reserved for those in the medical community, performed the best in their test. However, since many Americans do not have access to those and have been using a mix of store-bought or homemade cotton and fabric facial coverings, Duke tested 13 other kinds of masks.The study, which was published Friday, was prompted when a professor at Duke’s School of Medicine was asked to assist a local group buying masks in bulk for the community. According to CNN, the professor wanted to make sure the masks they bought were effective.Researchers gathered 14 kinds of masks, including the professionally-fitted N95 mask, a bandana, homemade cotton varieties, and a surgical mask. They then used a dark room, laser beam and cell phone camera to record how many droplets (which reflect the laser beam light) each mask allows through.For each mask test and the non-mask wearing control test, the speaker was recorded saying “Stay healthy, people” five times. Each mask was tested ten times. 1229

  

Authorities in Texas say a partially-dressed woman who was captured on a home surveillance system ringing a doorbell early one morning is safe after officials discovered her boyfriend died of a self-inflicted gunshot wound.According to ABC News, five days after the 32-year-old woman was recorded on a Ring doorbell’s surveillance camera, the woman was located and is reportedly safe, police said.The Montgomery County Sheriff's Office said on Wednesday they responded to a home in the Sunrise Ranch subdivision after receiving reports of a 49-year-old man threatening to kill himself.Deputies attempted to knock on the door multiple times before making forced entry into the home, officials said. When they made their way inside, they discovered the man lying dead of a single gunshot wound.Authorities tell local news outlets they believe his death is a suicide.The man left a note and mentioned his girlfriend but police say she was not at the scene by the time officers arrived. The woman was later identified as the person ringing a stranger's doorbell early in the morning.Last Friday, the woman was seen ringing a doorbell in the neighborhood north of Houston around 3:20 a.m., the MCSO said. The woman left the home before the resident answered the door.The eerie video of the woman was widely shared on the Internet as people on social media feared the woman — who was seen only wearing a T-shirt and broken hand restraints — was in danger. Authorities aren’t releasing any information about the woman because she is a victim of domestic violence. However, local media outlets report that she is from the Dallas area and is staying with family.Officials say they'll be meeting with the woman as the investigation continues.SEE VIDEO BELOW: 1776
