Researchers image quasiparticles that could lead to faster circuits, higher bandwidths
A research team led by Iowa State University's Zhe Fei has made the first images of half-light, half-matter quasiparticles called exciton-polaritons. The discovery could be an early step to developing nanophotonic circuits that are up to 1 million times faster than current electrical circuits. The researchers report their finding in the scientific journal Nature Photonics.
Iowa State veterinarians work to strengthen food safety and drug efficacy in pork production
Iowa State University veterinarians are taking a closer look at how commonly prescribed antibiotics move through and exit pigs. The research has implications for pork production practices and for food safety.
Concrete for taller wind turbine towers passes tests, could help expand wind energy nationwide
A research team led by Iowa State's Sri Sritharan has just finished an 18-month, $1 million study of concrete technology for taller wind turbine towers. Sritharan said lab tests demonstrate the technology will work. Economic studies also say the technology can be cost competitive. Sritharan said the taller towers could enable wind energy production in all 50 states.
Emotional toll from mass trauma can disrupt children’s sense of competence
Traumatic events, such as a terrorist attack or natural disaster, can have a profound effect on children's perceptions of competence – or how they view their ability to control a situation. Children with higher levels of competence were overall more resilient and had fewer PTSD symptoms, according to a new study by an Iowa State University professor.
Iowa State veterinary medicine student named Howard Hughes Medical Research Fellow
A third-year student in the College of Veterinary Medicine has received a Howard Hughes Medical Institute Medical Research Fellowship. Katherine Turnbull is one of 79 medical and veterinary students selected to conduct in-depth, mentored biomedical research at top institutions throughout the United States. Turnbull will spend a year pursuing research on septicemia at the University of Michigan.
Family history of Alzheimer’s may alter metabolic gene that increases risk for disease
A new Iowa State University study may have identified the link that explains years of conflicting research over a mitochondrial gene and the risk for Alzheimer’s disease. Researchers found a dramatic difference in the gene’s impact on memory, general cognitive function and risk based on a family history of Alzheimer’s disease and the length of a specific section of the gene.
Cyclone Power Pullers refine tractor for maximum efficiency ahead of June competition
The 2017 Cyclone Power Pullers hope to build on the success of previous years by refining concepts and components that worked well in past competitions. The team designed and built their quarter-scale tractor, called the ExCYter, from scratch this academic year.
Cyclone Space Mining tests for reliability, builds confidence for NASA contest
The student-engineers of Cyclone Space Mining think they've built tougher, more-reliable mining machines this year. The team's two robots will be tested May 22-26 as they attempt to mine simulated Martian soil at NASA's annual Robotic Mining Competition at the Kennedy Space Center in Florida.
Ames Laboratory celebrates 70 years of science, discovery on Iowa State’s campus
The U.S. Department of Energy's Ames Laboratory is celebrating 70 years on the Iowa State University campus. The close university-laboratory ties have helped recruit researchers, educate students, build research teams and make scientific discoveries possible.
After receiving bad advice, bullying victims say they would give same bad advice to others
Targets of workplace bullying get plenty of advice from coworkers and family on how to respond to the situation and make it stop. While well intentioned, much of the advice victims receive is impractical or only makes their situation worse. Despite the bad advice, most victims said they would tell others in their situation to do the same thing.
New study upends established models of forecasting coextinction in complex ecosystems
Newly published research from ISU scientists shows many species may not be as susceptible to coextinction events as once thought. This new understanding hinges on how dependent individual species are on their mutualist relationships.
New Iowa State University research will help to refine treatments for global parasitic disease
ISU biomedical researchers have broken new ground in understanding the genome of a parasitic roundworm that infects 2 million people worldwide. The research could lead to more effective treatments to combat the parasites.
How Pokémon GO can help students build stronger communication skills
Technology continues to change the way students learn and engage with their peers, parents and community. That is why Emily Howell, an assistant professor in Iowa State University’s School of Education, is working with teachers to develop new ways to incorporate digital tools in the classroom, including playing games such as Pokémon GO.
