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

NASHVILLE, Tenn. -- When you think of Nashville, you think bright lights and big music. Poverty is not part of its image. “There’s so many creative people that never get a chance to do anything with it. You’re too busy trying to survive, trying to eat, trying to stay alive,” said Chris Bandy, an artist. But poverty does exist in Nashville, and the rest of the U.S. At a house on the east side of the city, some of those living on less are doing a little more. “I’m doing what I was meant to be, you know, being a practicing, creative artist,” said Kateri Pomeroy, a Nashville artist. She uses the studio space at Poverty for the Arts. Pomeroy and her husband Sam are two of the first artists to join POVA, as it’s known. Sam was finishing up a wood sculpture he’s been working on. POVA was started by Nicole Minard as a way to help people who didn’t have access to art supplies and studio space. “I really saw the breadth of talent so many people on the streets had, and I would get questions like, ‘how can I get my art in a coffee shop?’ or ‘people see me drawing on the street every day, how do I get it to them without a cop pulling up and stopping me?’” said Minard. Minard provides the space, and the supplies for people who want to create art and she helps them sell it. POVA pays artists 60 percent of the selling price. They reinvest the other 40 percent into rent and supplies. “In those five years since we’ve started, we’ve served over 75 different artists and we’ve paid out over ,000 to artists on the street,” said Minard. The program gives exposure for artists who otherwise wouldn't have it. “If you don’t have the right school, the right gallery, the right representation, you really don’t get seen,” said Bandy For those that use the space to paint, draw or scribble, POVA is a place to prove they belong, even if they've known their potential all along. Edwin Lockridge was born with a paintbrush in his hand. “My parents actually have pictures of me, photographs of me as a baby with a pen and paper in my hands,” said Lockridge. But life has been rough for him and his family. “My mother and my father both have Alzheimer's bad, excuse me. I admit that I’m not in the best of health myself,” Lockridge said. To him, POVA is a matter of life and death. “The revenue from my art buys art supplies, medicine, necessary stuff to keep me alive for my basic survival," said Lockridge. For Pomeroy, Bandy and Lockridge, POVA provides opportunities they could not have thought possible. “This place has given me a transfusion, a new blood, and a new way to live" said Pomeroy. “We are family,” said Bandt. “There are no words, there are no words. This is my extended family without a doubt,” said Lockridge.That sense of family and community is a work of art no one can put a price on.   2838

Grocery stores often use tricks to get shoppers to stay inside longer and spend more money. In fact, the same techniques grocery stores use to get shoppers to stay longer are some of the same tricks casinos use to get us to gamble. Erin Chase with 261
