A study from University of Illinois economics professors demonstrates a new method to analyze the relationships among voters´ issue preferences, the candidates´ policy positions and voter behavior. Estimating the distribution of voter preferences and the extent of policy divergence between the candidates´ platforms, economics professors Stefan Krasa and Mattias Polborn are able to separate observed changes in voter behavior into those driven by voter radicalization versus...

A Look At The Early Evolution Of Sex Chromosomes
2012-08-06 18:24:30

Two new studies offer insight into sex chromosome evolution by focusing on papaya, a multimillion dollar crop plant with a sexual problem (as far as growers are concerned) and a complicated past. The findings are described in two papers in the Proceedings of the National Academy of Sciences. The research reveals that the papaya sex chromosomes have undergone dramatic changes in their short evolutionary histories (they are about 7 million years old; by comparison, human sex chromosomes...

Sand Diverted From River To Rebuild Wetlands Using Spillways
2012-07-25 08:42:43

Researchers could have a new method to rebuild wetlands of the Louisiana delta, thanks to a chance finding while monitoring severe flooding of the Mississippi River. A team of civil engineers and geologists from the University of Illinois, in collaboration with the U.S. Army Corps of Engineers, published their findings in the journal Nature Geoscience. In the spring and summer of 2011, high floodwaters on the Mississippi prompted the corps to open the Bonnet Carre spillway. The spillway...

Resolution And Durability Improved By Microscope Probe-sharpening Technique
2012-07-06 12:06:52

A simple new improvement to an essential microscope component could greatly improve imaging for researchers who study the very small, from cells to computer chips. Joseph Lyding, a professor of electrical and computer engineering at the University of Illinois, led a group that developed a new microscope probe-sharpening technique. The technique is described in research published this week in the journal Nature Communications. Scanning probe microscopes provide images of tiny structures...

Steve Moose, an associate professor of maize functional genomics at the University of Illinois and his graduate student Wes Barber think they may have discovered a new source of heterosis, or hybrid vigor, in maize. They have been looking at small RNAs (sRNAs), a class of double-stranded RNA molecules that are 20 to 25 nucleotides in length. “Hybrid vigor” refers to the increased vigor or general health, resistance to disease, and other superior qualities arising from the...

A 150-foot-high garbage dump in Colombia, South America, may have new life as a public park. Researchers at the University of Illinois have demonstrated that bacteria found in the dump can be used to neutralize the contaminants in the soil. Jerry Sims, a U of I associate professor of crop sciences and USDA-Agricultural Research Service research leader and Andres Gomez, a graduate student from Medellín, Colombia, have been working on a landfill called “El Morro” in...

Nowhere To Hide: Bacteria Behind The Eardrum Seen with New Device
2012-05-30 08:37:02

Doctors can now get a peek behind the eardrum to better diagnose and treat chronic ear infections, thanks to a new medical imaging device invented by University of Illinois researchers. The device could usher in a new suite of non-invasive, 3-D diagnostic imaging tools for primary-care physicians. The research team, led by University of Illinois electrical and computer engineering professor Stephen Boppart, will publish their advance in the online Early Edition of the journal Proceedings...

While climate change is likely to alter the spatial distributions of species and habitat types, the nature of those changes is uncertain, making it more difficult for conservationists to implement standard planning models. Research from applied economists at the University of Illinois shows that adapting a theory from the world of finance could help to optimize conservation activities. Using wetland habitat conservation in the Prairie Pothole Region as a case study, Amy W. Ando and Mindy...

Through a combination of atomic-scale materials design and ultrafast measurements, researchers at the University of Illinois have revealed new insights about how heat flows across an interface between two materials. The researchers demonstrated that a single layer of atoms can disrupt or enhance heat flow across an interface. Their results are published this week in Nature Materials. Improved control of heat exchange is a key element to enhancing the performance of current technologies...
