Many parents are wondering how schools could look different if they reopen in the fall. The Pima County, Arizona, superintendent toured a charter school today. The principal of Da Vinci Tree Academy invited Dustin Williams to look at a preliminary model that follows CDC guidelines. Williams says, “I saw the partitions up and I said, Whoa. I haven't seen a model like that. This is one of the first models I've seen in class. But I have to accept we're in unprecedented times and safety has to be paramount for everybody.” <div class="Figure-credit" itemprop="author">KGUN 906

CHICAGO, Ill. – Shortages of ventilators and personal protective equipment mean many healthcare providers are going into battle unarmed. It’s sparked a heated debate behind closed doors about balancing efforts to save patients versus exposing doctors and nurses to the virus. Who lives? Who dies? Who gets priority to a ventilator? All complex questions health providers are being confronted with. “We've never had this situation before. This is unprecedented,” said Craig Klugman a professor of bioethics at DePaul University in Chicago. Bioethicists say widespread infection, protective equipment and ventilator shortages are creating unique ethical dilemmas for healthcare workers. “We will start to care for the person who is at risk of dying first,” explained Dr. Ricardo Gonzalez-Fisher, a surgical oncologist who teaches healthcare ethics at Metropolitan State University of Denver. “But if we have more people than resources that we have to. Try to save those that are savable.” “The obligation for a healthcare provider to treat the patient doesn't necessarily have a limit,” said Klugman. In Spain, some 13,000 medical workers have been infected. In Italy, more than 60 workers have died since the outbreak began. “It's not just their life. They can assume this risk for themselves,” said Klugman. “If they don’t have the right equipment, they also have the risk of infecting other patients, other healthcare providers. Their family.” Some health systems around the country are reportedly discussing unilateral do-not-resuscitate policies. It’s something that was debated during the Ebola outbreak in 2015. Determining who gets treatment and who does not is something Klugman says is taken very seriously. “We think about it very carefully and with great deliberation.” In Italy, that meant denying some care to the elderly in favor of the young. Klugman says in Illinois, a pandemic flu plan created a decade ago includes care procedures built around ethical frameworks and algorithms that help decide who should for example, get a ventilator. “We have to consider things like what is our most important value. So, the value that we're considering is maximizing the number of years of life that we can save,” said Klugman. Ultimately, a balance must be struck. “You have to make sure that the benefit of the patient overrides the harm or the risk that you're getting in,” said Dr. Gonzalez-Fisher. Otherwise, bioethicists say there may not be enough first responders to treat the infected.“When you call 9-1-1 because your loved one can't breathe, there will be nobody coming. That's the worst-case scenario,” said Klugman. 2653

BALTIMORE, Md. – In looking for creative inspiration, engineering student Qiyuan Fu finds it in a box, with an interesting occupant. Inside: a real, live snake. “We can definitely learn something from them,” Fu said. The snake is a Kingsnake, which is native to deserts in California and Mexico and serves as the model for a new robot, developed in a mechanical engineering lab at Johns Hopkins University. “We added this one directional wheel, so it can only rotate in one direction,” said Fu, as he demonstrated how the robot moves. The “snake robot,” and its colleague, the “roach robot,” are so-called “bio-inspired robots” – taking their cues from mother nature. “We studied snakes here because they are exceptionally good at moving through almost any terrain,” said Johns Hopkins assistant professor Chen Li. Li said it’s an idea with practical applications: the robots could potentially help in search and rescue, by making their way through tight spaces to find people trapped in rubble. “People have actually tried to build snake robots for several decades,” he said. In the past, though, the robots fell short once they left the lab environments, unable to make it through different types of terrain. This time – using specially positioned cameras – they’ve observed how the snakes and roaches move across different surfaces and attempted to mimic what nature already does so well. “What's really unique about our work is that we focus on understanding the physical principles – starting by looking at animals,” Li said. “And then by understanding such principles, we can apply them to the to the robot.” The snakes have 200 vertebrae; the snake robot has 20 segments. It’s progress, these engineers say, with more to go. “There’s still going to be a lot of challenges ahead,” Li said.The engineering lab is now looking into modeling robots based on lizards. That’s because of their ability to leap across surfaces, which could further help robots make their way across uneven terrain. 2008

A Port St. Lucie man is recovering after he was bitten on the leg by an 8-foot alligator while walking his dog over the weekend, authorities said.According to the Florida Fish and Wildlife Conservation Commission, Mark Johnson, 61, was attacked near a canal in a Port St. Lucie development around 9:30 a.m. on Sunday."I kind of slide and my foot is stuck in the mud, and the next thing I know, I see the lunge," Johnson said. "He starts clamping down pretty tight and he started to pull, and the next thing I do, I instantly, here's my fingers, I poke through the eye."Johnson said the gator was trying to drag him under the water, spinning while clamping down on the victim's leg."This gator was coming in fast. He was aggressive," Johnson said. "My foot was hanging out of the corner of his mouth."Johnson said that after he poked the gator in the eye, it let go of his leg and took off."I had to do something. That's what I say, you have seconds to react," Johnson said.The victim was taken to a local hospital, where he received 62 stitches in his right left and was later released.Johnson said his dog Rex was not hurt.The FWC said an alligator trapper responded to the area of the attack and captured an 8-foot gator. The reptile was then relocated to an alligator farm.People with concerns about gators should call FWC's nuisance alligator hotline at 1-866-FWC-GATOR (866-392-4286).
