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

For the ladies in this gym, age isn't the number that matters most. "I’m going to be building up to 200. I want to get that done before I’m 80 years old,” says 78-year-old Bonnie Thurston on how much she can deadlift. Thurston says she’s been active her whole life, but never thought she would powerlift. Seven years ago, Thurston struggled with osteoporosis, a condition in which bones become weak and brittle, increasing risk of fractures. Then, Thurston found a powerlifting group for seniors. "I now weigh more than I weighed when I started this, but I wear the same size clothes, and the reason is I have stronger bones and larger bones and more muscle in my body than I did when I started this," she says. These group of seniors deadlift; they bench and they pull sleds. And while Thurston is doing all of this, she pushes 80. Thurston is not even the oldest person at the gym. Edith Murway-Traina is a member and is 97 years old. “I've always had muscles, I just had to learn to use them," she says. Bill Beekley leads the group. He's trained powerlifters since the 90s. "Don't be intimidated by what these ladies are doing, because they all started just moving their bodies," Beekley says. He says lifting correctly can help increase bone density and fight conditions like osteoporosis. It also helps these women in everyday life. "It's very functional,” the instructor says. “Some say they can carry their groceries a little easier now and don't need help getting groceries in an out of the car.” For 97-year-old Murway-Traina, she says that movement is so important as she nears 100. “The more you move, the more exercise you get, the more your body responds,” she says. Murway-Traina says she was nervous about the idea of powerlifting at first, but she now does it three times a week. "When you start being too old for something, you are too old for something, you have to know you are capable of doing what you want to make yourself do," Murway-Traina says. Research agrees. A JAMA study found physical activity in later life is linked to a lower risk of dying, even in older people who haven't been very active.Murway-Traina wants other seniors not to let the weight of getting older stop them from giving this a try. 2253

Former New Jersey Gov. Chris Christie remains hospitalized, but called a New Jersey newspaper editor from his hospital bed Monday morning, reportedly sounding raspy but not coughing — and fiery as ever.The former governor has struggled with asthma all his life, and announced on Twitter Saturday that he would check himself in to Morristown Medical Center on the advice of his doctors.Christie was seen outdoors in the White House Rose Garden hugging people without a mask last week. He also came in close contact with President Donald Trump and his staff when helping to prepare him for last week's debate."No one was wearing masks in the room when we were prepping the president during that period of time," Christie told Good Morning America. "The group was about five or six people in total."Monday, New Jersey Gov. Phil Murphy wished his predecessor a speedy recovery."He and I have had private communications," said Murphy. "He is in our prayers and he knows that we're here for him."The state is currently working to contact trace 206 people who attended a Trump fundraiser at his private golf club in Bedminster last week. Trump and his staff were there just hours before the president announced that he'd tested positive for COVID-19.The New Jersey Attorney General is now investigating whether the fundraiser violated state rules on social distancing. Many in attendance did not wear masks. But the Republican National Committee has insisted that face masks were provided and the event was in compliance.At Murphy's afternoon press briefing, he said the president and his staff acted recklessly by coming to New Jersey, knowing they had come in contact with someone who tested positive.“The actions leading up to and during this event have put lives at risk,” Murphy said.Some of the event attendees flew in from other parts of the country and have now scattered."This never should have happened," said the governor.

A 72-year old woman was gored by a bison in Yellowstone National Park on Thursday, June 25.A news release from park officials says the tourist approached within 10 feet of a bison several times to take its photo, and the bison gored her. It happened Thursday evening at the woman's campsite at Bridge Bay Campground.Rangers provided immediate medical care to the woman who sustained numerous goring wounds. She was then flown via helicopter to Eastern Idaho Regional Medical Center.“The series of events that led to the goring suggest the bison was threatened by being repeatedly approached to within 10 feet,” said Yellowstone’s senior bison biologist, Chris Geremia. “Bison are wild animals that respond to threats by displaying aggressive behaviors like pawing the ground, snorting, bobbing their head, bellowing, and raising their tail. If that doesn’t make the threat (in this instance it was a person) move away, a threatened bison may charge. To be safe around bison, stay at least 25 yards away, move away if they approach, and run away or find cover if they charge.”This is the second incident of a bison injuring a visitor in 2020; the park re-opened several weeks ago after a prolonged COVID-19 closure.Several recent incidents involving visitors and wildlife at Yellowstone:Earlier this month, a visitor was knocked to the ground after getting too close to a bison.In July 2019, a group of about 50 people got too close to a bison, which then charged and knocked a 9-year-old girl into the air. Click here for details and video.A visitor to Yellowstone recorded in May of 2019 a small dog running around and barking at two bison .In July of 2018, a man was caught on camera taunting a bison on a road in Hayden Valley. He was later sentenced to 130 days in jail by a federal judge in Wyoming.In September of 2018, a man was knocked down by an elk while standing on the side of the road. He was not injured.Park officials say that animals in Yellowstone National Park are wild. When an animal is near a trail, boardwalk, parking lot, or in a developed area, visitors must give it space. Stay 25 yards away from all large animals – bison, elk, bighorn sheep, deer, moose, and coyotes - and at least 100 yards away from bears and wolves.The Bison is the largest mammal in North America. Males can weigh up to 2,000 pounds and stand up to six feet tall, according to the Department of Interior. This article was written by David Sherman for KRTV. 2477

Once a week, Karelia Lanuza comes by Viola Zilio's apartment to help her with whatever she might need, whether it’s finishing a puzzle, helping with chores or reminding her to take her medications. The two will often run errands or go for walks. Often times, they’ll even stop at Zilio’s favorite café to get the traditional Cuban coffee. Lanuza isn’t a traditional caregiver. She more of a companion, according to Zilio. The pair met when Lanuza signed up to work for Papa, a new app and phone-based service for seniors. "Papa connects college students to older adults for companionship, assistance, and transportation,” says CEO and founder Andrew Parker. “It’s kind of like a grandkid on-demand." Parker thought pairing college students with seniors could fill a void he saw. “My grandfather, who we call papa, needed help but wasn't really ready for traditional healthcare services, and I thought it was weird there was nothing available before that,” Parker says. “So, I thought it would be interesting to connect him to college student, and he loved it.” Lanuza is a sophomore pre-med student, and she needed a job that fit with her busy class schedule. She passed the company's background and personality checks and got the gig. “I came over. I met Viola and we clicked instantly,” Lanuza says. “And from there, I’ve been coming every Tuesday to see her, and we hang out. It’s just like hanging out with a friend.” Zilio says Lanuza gives her someone to talk to. "Seeing her once a week is kind of like being like another grandmother to me,” Lanuza says.Currently in the Miami area, Papa costs around an hour. The service is only operating across Florida right now, but the company says they have plans to expand to several more cities nationwide soon. 1777
