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

Lending a helping hand is what Stephen Peth loves to do. Peth spends a lot of his time in the rehabilitation unit at Walter Reed National Military Medical Center in Bethesda, Maryland, helping wounded warriors get back on their feet. "The job is basically to do whatever we can to help the therapist," Peth explains. At 72 years old, Peth couldn't imagine any other way to spend his time. “I could be out on a golf course doing something for me, but to be here and be working for these wonderful service people that are here for a variety of reasons, to me, that’s inspirational,” he says. Peth says he’s inspired by all the patients he sees, because, he too, was once a warrior wounded in combat. "This is the boot that I was wearing the day that I got shot," he says. In 1967, 11 months into his tour during the Vietnam War, Peth, an army rescue helicopter pilot, was attacked by gunfire. "We took 39 hits on the aircraft,” he recalls. “I took a round through my boot and took a round though my arm." That dangerous mission earned him one of the highest awards of valor. "Gen. Craton Abrams came out and pinned a Silver Star on me," he says.His award and scars serve as reminders that he was once where these war heroes are now, compelling him find a way to serve his country once more. 1305

A report looking at cell phone data and geographical increases in COVID-19 cases, has estimated more than 260,000 cases nationwide were a result of the Sturgis motorcycle rally held in South Dakota.The 63-page report looked at the potential results of a “superspreader” event; an event where “large crowds, coupled with minimal mask-wearing and social distancing by attendees.” It included researchers from San Diego State University, Bentley University and University of Colorado Denver. The results were issued over the weekend and have not been peer reviewed at this time.The same group has looked at other events, like Black Lives Matter demonstrations nationwide and President Donald Trump’s rally in Tulsa.For the Sturgis event, they identified counties which saw lots of rally-goers and tracked COVID-19 cases before and after the event in those areas using available CDC data.Roughly 500,000 people attended the event, according to information from the South Dakota Department of Transportation, which ran from August 7 to 16.Their research found in counties nationwide who had a lot of Sturgis attendees, the COVID-19 case count in their home counties increased about 10.7 percent from about a month before to a few weeks after the rally."Under the guise of academic research, this report is nothing short of an attack on those who exercised their personal freedom to attend Sturgis,” Gov. Kristi Noem said in the statement to The Argus Leader. "Predictably, some in the media breathlessly report on this non-peer reviewed model, built on incredibly faulty assumptions that do not reflect the actual facts and data here in South Dakota."The state has reported 124 cases of COVID-19 of South Dakota residents who attended the rally.Last week, state health departments in various states issued warnings about residents who may have contracted COVID-19 at the Sturgis rally. States are relying on patients who test positive to report the possible exposure at the motorcycle rally. "We're never going to be able to contact trace every single person from Sturgis," Andrew Friedson, one of four authors of the study said. "So if we want a good-faith estimate using, at the moment, the accepted statistical techniques ... this is the best number we're going to get in my opinion."Using findings from another team of researchers, the team estimates the Sturgis rally may have generated a public health cost of about .2 billion. The other study looked at the average cost of non-fatal COVID-19 cases, and put the estimate around ,000 per patient. 2576

MILWAUKEE -- One of the Milwaukee County Zoo's harbor seals has died days after she gave birth to a seal pup, Zoo officials announced Tuesday.Sydney, who arrived at the Zoo in 2005 after being rescued as an orphaned pup herself, gave birth to a male seal pup on June 3. Three days later, Sydney died unexpectedly. Officials say a preliminary necropsy shows Sydney died of a "systemic infection" - which begins in one area and then moves to the bloodstream, affecting the entire body.The pup, who has not yet been named, is being hand-raised by zookeepers and animal care staff. He was the fifth pup born to Sydney and her companion, Ringo."Keepers are assist-feeding the pup five times daily with a milk replacer formula made specifically for marine mammals which includes a high fat content and vitamins," a news release from the Zoo says. "Normally, harbor seals nurse 4-6 weeks before weaning. In the meantime, finely ground fish is gradually being added to the formula. As of June 23, in addition to the formula feedings, the pup has been introduced to live fish to pique his natural instincts.""Keepers comment [Sydney] was extremely smart, and through training sessions, taught them how to be patient, calm and reliable...Sydney will be missed by her keepers and visitors," the Zoo says.This article was written by WTMJ. 1346
