U. Iowa researchers improve Huntington's disease symptoms in mice

Researchers at the University of Iowa Roy J. and Lucille A. Carver College of Medicine have taken another step toward a potential treatment for Huntington's disease (HD). Using an approach called RNA interference (RNAi), the scientists reduced levels of the disease-causing HD protein in mice and significantly improved the movement and neurological abnormalities normally associated with the diseas...

Iowa State researchers improving plastics made from corn and soy proteins

David Grewell picked up the little plastic model of a molecule he keeps in his office. He scrunched the model's folding pieces into a ball. That's about the shape of a soy or corn protein, said Grewell, an Iowa State University assistant professor of agricultural and biosystems engineering. Then he unfolded the model into a long, straight loop. That's what happens when researchers add some glycer...

University of Iowa scientists explore function of 'junk DNA'

University of Iowa scientists have made a discovery that broadens understanding of a rapidly developing area of biology known as functional genomics and sheds more light on the mysterious, so-called "junk DNA" that makes up the majority of the human genome. . The team, led by Beverly Davidson, Ph.D., a Roy J. Carver Biomedical Research Chair in Internal Medicine and UI professor of internal medic...

Iowa State University botanists identify new species of North American bamboo

Two Iowa State University botanists and their colleague at the University of North Carolina have discovered a new species of North American bamboo in the hills of Appalachia. It is the third known native species of the hardy grass. The other two were discovered more than 200 years ago. . Lynn Clark, Iowa State professor of ecology, evolution and organismal biology, and Ph.D. student Jimmy Tripl...

ConocoPhillips establishes $22.5M biofuels research program at Iowa State

ConocoPhillips will establish an eight-year, $22.5 million research program at Iowa State University dedicated to developing technologies that produce biorenewable fuels. The grant is part of ConocoPhillips' plan to create joint research programs with major universities to produce viable solutions to diversify America's energy sources. . .. Biorenewable fuels are produced from organic materials...

Iowa State scientists demonstrate first use of nanotechnology to enter plant cells

A team of Iowa State University plant scientists and materials chemists have successfully used nanotechnology to penetrate plant cell walls and simultaneously deliver a gene and a chemical that triggers its expression with controlled precision. Their breakthrough brings nanotechnology to plant biology and agricultural biotechnology, creating a powerful new tool for targeted delivery into plant ce...
