In the past 20 years, Martin Luther King's dream of the day when "little black boys and black girls will be able to join hands with little white boys and white girls" through school desegregation has not been realized for most, according to research by an Iowa State University economist. David Frankel, associate professor of economics, looked at public school enrollments from every school district in the country and found that school segregation between blacks and whites has improved only...

Researchers study flu proteins in-depth to identify virus vulnerabilities Each year, people everywhere prepare for flu season. Some will get the flu vaccine, some take vitamin supplements, some launch a vigorous handwashing campaign, while others take an entirely different approach: nuclear magnetic resonance (NMR). Mei Hong, a chemist at Iowa State University, uses NMR to study a proton channel named M2, found on the surface of the influenza virus. This proton channel has been the subject of...

Last week, the Orlando Sentinel newspaper reported that Palm Beach County, Fla., law enforcement is working to develop a consistent set of rules for eyewitnesses, hoping it will help prevent false convictions. And a new Iowa State University study published in the Journal of Experimental Psychology finds that there may be good reason to question the recall of some eyewitnesses. The study summarizes two experiments conducted by Jason Chan, an ISU assistant professor of psychology; and Moses...

The work could lead to improved methodologies for creating materials by design Scientists have given us a plethora of new materials "“ all created by combining individual elements under varying temperatures and other conditions. But to tweak an intermetallic compound even more, in order to give it the attributes you desire, you have to go deeper and re-arrange individual atoms. It's a process similar to what bioengineers employ when they add and delete genes to create synthetic...

Nearly one out of every 10 kids who play video games become addicted to them, and those pathological gamers could develop a plethora of mental health problems if their addiction is not properly dealt with, claims a new study published in the February 2011 edition of the journal Pediatrics. As part of the study, researchers analyzed 3,034 school children attending third through eighth grade at 12 different schools in Singapore. They discovered that 83% of those kids played games regularly, and...

Michael Kessler has worked with polymers that repair themselves when they crack. And he's worked with polymers made from vegetable oils. Now he's working to combine the two technologies. Kessler, an Iowa State University associate professor of materials science and engineering and an associate of the U.S. Department of Energy's Ames Laboratory, is researching and developing biorenewable polymers capable of healing themselves as they degrade and crack. "If successful, the results of this...

An international team of scientists has released data indicating that greenhouse gas uptake by continents is less than previously thought because of methane emissions from freshwater areas. John Downing, an Iowa State University professor in the ecology, evolution and organismal biology department, is part of an international team that concluded that methane release from inland waters is higher than previous estimates. The study, published in the journal Science, indicates that methane gas...

Researchers from Iowa State University and the Ames Laboratory have developed a process capable of producing a thin and uniform light-absorbing layer on textured substrates that improves the efficiency of polymer solar cells by increasing light absorption. "Our technology efficiently utilizes the light trapping scheme," said Sumit Chaudhary, an Iowa State assistant professor of electrical and computer engineering and an associate of the U.S. Department of Energy's Ames Laboratory. "And so...
