Genetic mutations to cellulose in plants could improve the conversion of cellulosic biomass into biofuels, according to a research team that included two Iowa State University chemists. Mei Hong, an Iowa State professor of chemistry and an associate of the U.S. Department of Energy's Ames Laboratory, and Tuo Wang, an Iowa State graduate student in chemistry, contributed their expertise in solid-state nuclear magnetic resonance spectroscopy to the study. The study was led by Seth DeBolt,...

The most recent annual results from a four-year Iowa State University study on using cover crops between rows of corn reveals that higher yields - by as much as 10 percent - are possible using the soil-saving approach to farming. The results are the best yet in the ongoing research, according to Ken Moore, Distinguished Professor of agronomy and primary investigator on the project, who plans to carry on the trials for at least one more growing season. Planting living mulch - or ground...

In the two and a half years since Adam Bogdanove, professor at Iowa State University in the Department of Plant Pathology and Microbiology, along with Matthew Moscou, a former graduate student in that department, discovered how a class of proteins from plant pathogenic bacteria find and bind specific sequences in plant genomes, researchers worldwide have moved fast to use this discovery. Last year it was first shown that the proteins can be fused to DNA modifying enzymes to manipulate...

A 'sin tax' applied to sweetened goods on store shelves is not the most efficient, effective method of lowering caloric intake from sweet food and would be more disruptive to consumers than necessary, according to Iowa State University research. With a national debate taking shape about the possibility of a national tax on foods with high sweetener content, ISU economists have examined how such a tax would best be applied. Rather than assessing a tax on these sugary goods as they are...

Savanna Chimps Exhibit Human-like Sharing Behavior
2011-12-02 04:59:09

Sharing food has widely been considered by scholars as a defining characteristic of human behavior. But a new study by Iowa State University anthropology professor Jill Pruetz now reports that chimpanzees from her Fongoli research site in Senegal also frequently share food and hunting tools with other chimps. Co-authored by ISU anthropology graduate student Stacy Lindshield, their study is posted online in Primates and will be published in a future issue of the journal. The researchers...

Research at Iowa State University has led to discovery of a genetic method that can increase biomass in algae by 50 to 80 percent. The breakthrough comes from expressing certain genes in algae that increase the amount of photosynthesis in the plant, which leads to more biomass. Expressing genes means that the gene's function is turned on. "The key to this (increase in biomass) is combination of two genes that increases the photosynthetic carbon conversion into organic matter by 50...

Study Finds Health Value To Children Of National School Lunch Program
2011-11-11 12:15:35

The federally funded National School Lunch Program (NSLP) provides free and reduced-price meals to more than 31 million children every school day, according to its website. And a recent study by current and former Iowa State University researchers confirmed that school lunches improve the health outcomes of children who reside in low-income households. The researchers analyzed data from nearly 2,700 NSLP children (ages 6-17) taken from the 2001-04 National Health and Nutrition Examination...

New processes that allow nanoparticles to assemble themselves into designer materials could solve some of today's technology challenges, Alex Travesset of Iowa State University and the Ames Laboratory reports in the Oct. 14 issue of the journal Science. Travesset, an associate professor of physics and astronomy and an associate of the U.S. Department of Energy's Ames Laboratory, writes in the journal's Perspectives section that the controlled self-assembly of nanoparticles could help...

Program Supports Education of Future Corn Plant Breeders Des Moines, IA (PRWEB) September 19, 2011 DuPont, through its Pioneer Hi-Bred business, has awarded a grant to Iowa State University to establish a corn breeding program through support of a new faculty position and a graduate research position. This position will be a leading authority on the application of modern technologies to plant breeding. Support for corn research and education of tomorrowâs plant breeders...

Image 1 - Helping Astronauts Make Their Drinking Water Clean
2011-09-15 13:18:37

  Bob Lipert held up a syringe, attached a plastic cartridge and demonstrated how chemistry developed at Iowa State University is helping astronauts and cosmonauts make sure they have safe drinking water at the International Space Station. Each cartridge contains a thin, one-centimeter disk that's loaded with chemistry, said Lipert, an associate scientist with Iowa State's Institute for Physical Research and Technology and an associate of the U.S. Department of Energy's Ames...
