  • Physicists use light waves to accelerate supercurrents, enable ultrafast quantum computing

    Iowa State's Jigang Wang and a team of collaborators have discovered that terahertz light --light at trillions of cycles per second -- can act as a control knob to accelerate supercurrents. That can help open up the quantum world of matter and energy at atomic and subatomic scales to practical applications such as ultrafast computing.

  • Designing better products for off-grid, backcountry situations

    A group of Iowa State University industrial design students recently spent two weeks “off grid” in the American Southwest — an experience that has sparked a slew of ideas for new products the students are now designing for backcountry adventures.

  • Four approaches to understanding and moving beyond dysfunctional deliberation

    It may feel like we have reached an impasse in the debate over divisive issues such as gun violence, climate change and immigration. Improving the level of discourse is not impossible, says Craig Rood, an assistant professor of English at Iowa State University, but he admits it will not be easy.  Rood offers four strategies for working toward understanding. 

  • Formula racers earn a top-10 finish, analyze the data to find even more speed

    The student-engineers of Iowa State's Formula SAE team have been spending sunny summer days trying to trim a few tenths of a second from the times posted by their race car. The students recently finished eighth overall at a competition in Canada. They're hoping for an even better performance this week at a competition in Lincoln, Nebraska.

  • Iowa State researchers studying slow-release fertilizer to feed crops, improve water quality

    A research project looking for ways to add value to biochar may have found an unexpected application for the black power that's a co-product of thermochemically converting biomass to a liquid bio-oil. The researchers have found biochar could be a slow-release fertilizer that delivers nutrients to crops while keeping those nutrients from washing away in the rain or leaching into groundwater. More uses for biochar could make thermochemical biofuel production a more economically attractive technology.

  • Antioxidant puts up fight, but loses battle against toxic protein linked to Alzheimer’s disease

    New research may explain why an antioxidant that protects the brain is also associated with deterioration in areas susceptible to Alzheimer’s disease. The antioxidant, superoxide dismutase or SOD1, improves cognition, but an Iowa State University research team found SOD1’s protective benefits dramatically weaken when levels of tau proteins – a hallmark of Alzheimer’s disease – increase.

  • Iowa State's Geetu Tuteja selected for Pew Scholars Biomedical Research Program

    Geetu Tuteja, assistant professor in Iowa State's department of genetics, development and cell biology, has been selected to join the Pew Scholars Program in the Biomedical Sciences. She is the first Iowa State researcher to receive this honor. Tuteja is one of 22 promising scientists nationwide selected by the Philadelphia-based Pew Charitable Trusts to receive a four-year, $300,000 grant to conduct biomedical research aimed at advancing human health.

  • New economic study shows combination of SNAP and WIC improves food security

    Forty million Americans, including 6.5 million children, are food insecure. Given the extent of food insecurity, a team of Iowa State University economists developed a methodology to analyze potential redundancies between two food assistance programs -- SNAP and WIC. Their research shows that participating in both programs compared to SNAP alone increases food security by at least 2 percentage points and potentially as much as 24 percentage points.

  • Iowa’s wet spring conforms with climate trends outlined in major 2018 assessment

    Wet and cool weather throughout May delayed planting and slowed the emergence of crops, according to an ISU agronomist. The weather falls in line with trends outlined in last year’s National Climate Assessment, and slow emergence could remain a problem throughout the 2019 growing season.

  • ISU experts look at long-term impact of tariffs on supply chain, consumers

    Businesses are preparing for the long-term impacts of the ongoing trade war between the U.S. and China. Consumers may not recognize the complexity and level of disruption created to points along the supply chain, but they are paying for it, say experts in Iowa State University’s Ivy College of Business. Cost is just one the consequences they expect to see in the fallout from the tariffs. 

  • Not all teens turn to social media when they’re lonely

    Technology is so pervasive it may seem as if teens spend more time on social networking sites than in real conversations with friends. New research challenges that assumption and finds some teens, especially when they feel lonely, prefer face-to-face interactions over social media. 

  • Iowa State climbs in ranking of top 100 worldwide universities granted U.S. utility patents

    Iowa State is tied for 69th in the world in the number of patents granted in the United States last year, according to a list released June 4 by the National Academy of Inventors and Intellectual Property Owners Association. The Iowa State University Research Foundation was granted 34 patents in 2018. ISU was ranked No. 83 in the previous year's ranking.

  • ISU students design proposals for new educational center in Iowa Judicial Building

    As the Iowa Judicial Branch Building shifts from physical to digital files, Iowa State University students have designed proposals to turn the soon-to-be-vacant space into an experiential learning center for the public.
