Researchers print, tune graphene sensors to monitor food freshness, safety
Researchers are using high-resolution printing technology and the unique properties of graphene to make low-cost biosensors to monitor food safety and livestock health.
Economic analysis shows how ISU soybean trials generate value for farmers
Farmers and seed companies in Iowa and Illinois saved millions of dollars in recent years because of data generated by Iowa State University field trials that tested soybean varieties resistant to the soybean cyst nematode. A new study used economic models to determine how willing farmers are to pay a premium for resistant soybean varieties compared to susceptible varieties.
Researchers building cyber-physical system to monitor crops, drive decisions, boost yields
Researchers at Iowa State University and the University of Nebraska-Lincoln are combining their expertise in electronics, computing and crops to develop a cyber-physical system that will monitor fields at almost single-plant resolution. The idea is to predict crop productivity and help farmers manage their water and fertilizer use. The project is supported by a $1 million grant from the U.S. Department of Agriculture.
Chemists developing paper-strip urine test for at-home/office/clinic COVID-19 evaluation
Robbyn Anand and her students are developing a paper-strip urine test to detect the coronavirus that causes COVID-19. The tests are based on Anand's expertise in electrokinetics, using electric fields to concentrate, separate, isolate and manipulate charged particles. A grant from the Research Corporation for Science Advancement is supporting the project.
Engineers work to keep power lines and bridge cables steady when windstorms blow
Iowa State engineers are doing wind-tunnel tests and computer simulations to understand and predict how the cables that carry power or support bridges will react to high winds. The goal is to prevent them from dangerously whirling in the wind, causing cables or structures to catastrophically fail.
Fall semester will start early at Iowa State
Iowa State University’s fall semester will start a week early and wrap up the day before Thanksgiving. In a letter today to the campus community, President Wendy Wintersteen announced several initiatives including changes to the academic calendar as well as plans for COVID-19 testing and contact tracing, class size and delivery and occupancy rates for the residence halls to limit the spread of illness on campus.
Link between liver and heart disease could lead to new therapeutics
A newly published study of flies found that protecting liver function also preserves heart health. The research could lead to new therapeutic approaches in human health and illuminate the role of understudied organelles known as peroxisomes.
Artist’s illustrations create ‘visual headlines’ about pandemic
Miriam Martincic, assistant teaching professor of graphic design at Iowa State University, is creating a series of illustrations about the COVID-19 pandemic. Her work includes drawings about social distancing, honoring health care workers and showing how the transition online feels for teachers.
Progress toward gender balance, but more work needed
Cities and counties across the state continue to work toward achieving gender balance on commissions and boards, according to a new report from the Catt Center for Women and Politics. While the report shows progress at both levels, Iowa State's Kelly Winfrey says there is still work to be done.
Iowa State makes list of top 100 universities for U.S. patents issued in 2019
The Iowa State University Research Foundation, Inc., which processes and holds patents tied to Iowa State research, has made the annual list of top 100 worldwide universities granted U.S. patents during a calendar year for the fifth time since 2013, when the rankings began.
New grant will help scientists advance human immune model in pigs
Scientists at Iowa State University are poised to take a significant step forward in human health by transferring a human immune system into pigs. The research was recently awarded a nearly $3 million grant from the National Institutes of Health to develop the technology over the next four years. The research could pave the way to new treatments for a wide range of health problems, from cancer to severe burns.
Patterns in crop data reveal new insight about plants and their environments
A new study unearthed patterns in datasets collected on rice plants across Asia that allowed researchers to develop a matrix to predict the traits of rice plants depending on their genetics and environment. The approach could lead to better predictability in crop production.
CARES Act, other funding sources help students complete spring semester
More than 7,000 Iowa State University students applied for assistance from the Office of Financial Aid due to hardship caused by the COVID-19 pandemic. The average grant is around $1,400.
