  • Engineers developing machine-learning tools to quickly, cheaply design better solar cells

    Iowa State engineers are working with collaborators to develop machine learning theories and software tools that can quickly and cheaply design better solar cells. Those theories and tools could also be applied to the rapid design of all kinds of new technologies. The engineers' research is supported by a grant of up to $2 million from the U.S. Department of Energy's Advanced Research Projects Agency -- Energy.

  • Stability at the top, growing opposition to Bloomberg, Steyer

  • Study shows integrated organic crop and livestock production systems can conform to food safety standards

    The integration of crop and livestock production on organic farms doesn’t appear to pose substantial food safety risks and could yield benefits for producers, according to a study involving Iowa State University scientists. The experiments involved three sites in the Midwest on which acres were rotated between organic crop and livestock production.

  • Burial traditions are evolving, designers see call to action

    Iowa State University interior design students are responding to changing beliefs and traditions surrounding funerals and burials in the United States by studying cemeteries, funeral homes, mortuaries and interment practices. By the end of this semester, each student designed a unique, never-before-seen space for the future of burial. 

  • Contributions of Iowa athletes featured in new book

    You don’t have to be a sports fan or athlete to find inspiration from the stories and artwork in an Iowa State professor's new book "Amazing Iowa Athletes." Katy Swalwell says all the athletes featured in the book faced various forms of oppression, but used their sport to do incredible things. 

  • Sorghum study illuminates relationship between humans, crops and the environment in domestication

    A new study illustrates the concept of a domestication triangle, in which human genetics interact with sorghum genetics and the environment to influence the traits farmers select in their crops. The concept gives a more complete systemic picture of domestication.

  • Regional trends in overdose deaths reveal multiple opioid epidemics, according to new study

    A recently published study shows the United States in the grip of several simultaneously occurring opioid epidemics, rather than just a single crisis. The epidemics came to light after the researchers analyzed county-level data on drug overdose deaths. The study highlights the importance of different policy responses to the epidemics rather than a single set of policies.
