A Southern Arizona school district is taking a creative approach to better sanitize the classroom daily.Santa Cruz Valley School District bought six Power Breezers that will disinfect a classroom in 20 minutes.Superintendent David Verdugo said the school district did this as a cost effective way to provide extra safety and security to students and staff.He said it will be used after school to clean empty classrooms, hallways and even school buses.Each unit costs about 4,500 dollars."This is an opportunity for them to look at a way to sanitize a room in a short period of time and utilize their staff but also be cost effective," Superintendent Verdugo said.He said the district is also requiring all students to wear masks, have their temperature checked, and social distance in and out of the classroom.Every classroom will only be at 50% capacity, meaning 15 desks per room, he said. In order to do this, the district came up with a hybrid approach to learning."There will be a group A and a group B," Superintendent Verdugo said. "The group A students will be on Monday. They will come to school, have their direct instruction and then they will be at home the next day. Then, group B will come to school, but they will still have some interaction that day with assignments and virtual opportunities."He said the district is planning on starting remote learning on August 3 and then the hybrid approach will being on August 31. KGUN's Veronika Vernachio was first to report this story. 1517

CHICAGO, Ill. -- Karate is well-known for teaching discipline, but its focus on core strength, balance and confidence-building could be effective for something else – helping people living with brain disorders such as Parkinson’s. Twice a week, inside a karate dojo in Chicago, students learn the fundamental movements of Kihon technique. “We did something called KoGo Kumite which is partner work, working on rhythm, working on distancing, working on timing and working on technique.” But for Fonseca Martial Arts head instructor Brian Ramrup this is a class like none other he’s taught before. “These guys all have Parkinson's,” said Ramrup. More than 1 million Americans have Parkinson’s disease. The progressive neurological disorder affects balance and movement. Tremors and stiffness are common symptoms, but the disease can also lead to depression and anxiety. For Sonia Vargas, diagnosed with Parkinson’s in 2005, it started with tingling in her legs. “It felt like I was carrying some piece of some heavy equipment on my legs,” said Vargas. A year ago, on the recommendation of her neurologist, Vargas joined the Chicago-area martial arts academy.“These guys are learning how to go to the ground safely, how to break falls,” said Ramrup. It’s a skill that can help avoid injuries for patients who begin to lose balance and fall frequently. It’s part of a program studying the potential for karate to slow the progression of the disorder. “When I went to the first class, the next day, I felt a difference. It was so remarkable,” said Vargas. Dr. Jori Fleisher is the principal investigator of the study and a neurologist at Rush University Medical Center. She says initial results are promising. “We found clinically significant changes in quality of life which is huge,” said Fleisher. “It's a great exercise covering a lot of the areas: balance, core strength, big large amplitude movements when people are kind of tiny or smaller, stiffer. They're sort of fighting back actively against that.” Camaraderie is also a key component. The group now competes together, cheering for one another on good days and bad. “The exercises help tremendously the competitions. I mean really gets you going. I mean my first competition I got I got the orange belt,” said Vargas. The year-long randomized program concludes next month, and Dr. Fleisher remains cautiously optimistic about the outcome.“I don't think karate will be the end all be all. It's not the answer, but could it be an answer? I think so.” 2521

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

The Macy's at Herald Square has begun boarding up windows, anticipating protests from the result of the 2020 Presidential Election. WPIX-TV cameras saw workers boarding up along the famous storefront Friday evening.A variety of Fifth Avenue stores were boarding up on Friday afternoon and some as early as 9 a.m. Many Manhattan stores were looted in the unrest following the death of George Floyd in late May and early June. 445
