A new green, bio-based method for producing a much-used fuel additive and industrial chemical that is currently made from petroleum products has been developed by an Iowa State University researcher. Thomas Bobik, professor of biochemistry, biophysics and molecular biology, invented a process for manufacturing isobutene (isobutylene) by identifying a new, natural enzyme that produces the fuel organically. Bobik, along with David Gogerty, a doctoral student working with him on the project,...

Engineers bring a critical perspective to the economic models and mathematical predictions that are used to influence public policy, says Iowa State mechanical engineer W. Ross Morrow. "With these quantitative models, people in policy and economics tend to take them at their word," said Morrow, an Iowa State University assistant professor of mechanical engineering with a courtesy appointment in economics. "Engineers bring a great skepticism about what the models say. They ask, 'What evidence...

They can't wait to do computational chemistry at a quadrillion calculations per second. But it's not all that computing power that's driving three Iowa State University and Ames Laboratory researchers as they develop computational chemistry at the petascale. Driving their project is the ability to run complex calculations and do better science. "Petascale power is required for accuracy," said Monica Lamm, an Iowa State assistant professor of chemical and biological engineering and associate...

Scientists are trying to determine why errors in eyewitness identifications occur, and how to prevent these errors Innocent people are sometimes convicted of crimes largely due to errors in eyewitness identifications. Scientists are trying to determine why this occurs, and how to prevent these errors. In studies funded by the National Science Foundation (NSF), Gary Wells, professor of psychology at Iowa State University, and an internationally recognized scholar in scientific psychology, has...

Researchers from Iowa State University's gerontology program have helped identify what predicts happiness and long life in centenarians, as well as what causes depression in 80-somethings and above. In a study of 158 Georgia centenarians, the researchers found that past satisfaction with life -- even if it's simply recalling isolated career accomplishments -- is the key to happiness in our oldest years. "The past is the best predictor of the future, so you're not going to turn your life...

Agronomists at Iowa State University are offering doubled haploid technology that allows corn breeders to more quickly produce inbred lines for research or private use. Thomas Lbberstedt, associate professor and K.J. Frey chair in agronomy and director of the R.F. Baker Center for Plant Breeding, has launched a Doubled Haploid Facility at ISU that can develop pure, inbred corn lines in less time than traditional methods. Inbred corn lines have two copies of the same genome. They are sometimes...

A new study from Iowa State University's Nutrition and Wellness Research Center (NWRC) may give men a way to combat high cholesterol without drugs -- if they don't mind sprinkling some flaxseed into their daily diet. Suzanne Hendrich, an ISU professor in food science and human nutrition, led a study that examined the effects of flaxseed lignan in 90 people diagnosed with high cholesterol. The results showed that consuming at least 150 milligrams of flaxseed lignans per day (about three...

Kerry Whisnant, Iowa State University physicist, studies the mysteries of the neutrino, the elementary particle that usually passes right through ordinary matter such as baseballs and home-run sluggers. Kerry Whisnant, St. Louis Cardinals fan, studies the mathematical mysteries of baseball, including a long look at how the distribution of a team's runs can affect the team's winning percentage. Whisnant, a professor of physics and astronomy who scribbles the Cardinals' roster on a corner of...

A previous six-month study by Iowa State University researchers had indicated that consuming modest amounts of soy protein, rich in isoflavones, lessened lumbar spine bone loss in midlife, perimenopausal women. But now an expanded three-year study by some of those same researchers does not show a bone-sparing effect in postmenopausal women who ingested soy isoflavone tablets, except for a modest effect at the femoral (hip) neck among those who took the highest dosage. The multi-center...

Antiviral drugs block influenza A viruses from reproducing and spreading by attaching to a site within a proton channel necessary for the virus to infect healthy cells, according to a research project led by Iowa State University's Mei Hong and published in the Feb. 4 issue of the journal Nature. Hong, Iowa State's John D. Corbett Professor of Chemistry and an associate scientist for the U.S. Department of Energy's Ames Laboratory, said the findings clarify previous, conflicting studies and...
