When the Press-Citizen spoke with her in January, Iowa City West student Dasia Taylor maintained she wasn't a scientist. But that hasn't kept the accolades from rolling in. The most recent award was broadcast Monday, when the 17-year-old sat across from TV talk-show host Ellen DeGeneres and explained her invention. "I set out to create cost-effective sutures that change color when an infection is present," Taylor said to DeGeneres at a taping of her show, which aired locally at 4 p.m. Monday on CBS. "And hey, now I'm here with you." Taylor explained to DeGeneres how she became interested in the subject after her teacher, Carolyn Walling, introduced the class to the Society for Science & the Public's Regeneron Science Talent Search. Though sutures similar to Taylor's existed previously, they used technology that demanded a high price point.
