  • New evidence may change timeline for when people first arrived in North America

    An unexpected discovery by an Iowa State University researcher suggests that the first humans may have arrived in North America more than 30,000 years ago – nearly 20,000 years earlier than originally thought.

  • Researchers build structured, multi-part nanocrystals with super light-emitting properties

    Researchers have combined two or three types of nanoparticles to produce new materials with structures known as superlattices. In some instances, the structures display fundamental new properties such as superfluorescence. The researchers' discovery is reported in the journal Nature and featured on the current issue's cover.

  • Engineered defects in crystalline material boosts electrical performance

    Researchers have discovered that engineering one-dimensional line defects into certain materials can increase their electrical performance. Their findings have been published in the journal Science.

  • Advancing diversity and inclusion in business requires a common language, knowledge

    Despite a growing momentum for initiatives aimed at creating more diverse and inclusive work spaces, several barriers still exist that limit the success of these efforts. To implement meaningful change, a team of researchers says a holistic and systematic approach is needed to ensure practitioners, educators and researchers are all working from the same playbook. 

  • Pollinating insects can help soybean yields

    Insects can help soybean yields by carrying out more effective pollination, according to a recently published study conducted by an international team of scientists. The study suggests introducing pollinator habitat to soybean fields may lead to production benefits, in addition to environmental advantages.

  • Change Agent: Dipali Sashital

    In Dipali Sashital’s eyes, the thrill of discovering something new is the most exciting part of being of a scientist. Sashital explores the mechanisms of CRISPR-Cas systems, which allow for precise cutting and editing of an organism’s genes. These technologies have the potential for revolutionary advances in human health and agriculture.

  • Mapping Iowa’s soil topography

    An Iowa State University agronomist is developing new computer models of soil erosion and topography changes, requiring both innovative big-data technology as well as painstaking validation of soil measurements in the real world. The National Science Foundation recently awarded Bradley Miller an early career development grant to support the research.

  • Glaciologists measure, model hard glacier beds, write slip law to estimate glacier speeds

    Researchers measured rock glacier beds to create high-resolution digital models they used to study how glaciers move along their bedrock bases. The resulting glacier "slip law" can be used by other researchers to better estimate how quickly ice sheets flow into oceans, drop their ice and raise sea levels.

  • The ‘key’ to new COVID-19 vaccine development

    An Iowa State University biomedical scientist is researching a new COVID-19 vaccine that would target only a small portion of the virus’s spike protein. The vaccine has shown promise in laboratory experiments, and more vaccines could be necessary in the years ahead as additional SARS-CoV-2 variants emerge.

  • Iowa State student named Udall Scholar

    Iowa State University has a Udall Scholar for the fourth year in a row. Nolan Monaghan, junior in horticulture and global resource systems, is well on his way to a career in sustainable agriculture.

  • Graduating ISU student has a plan: Use research to solve global problems

    A couple of commercials sparked a journey that would eventually lead Behnia Rezazadeh Shirazi from Iran to Iowa. Shirazi will graduate from Iowa State this weekend with bachelor’s degrees in biology, biophysics and biochemistry. He's looking toward a career in the biotech industry, with hopes to solve global challenges from cancer to Alzheimer's disease.

  • Graduating senior pursued passion for marine biology at landlocked Iowa State

    Iowa State may not be the first university you think of when it comes to marine biology. That didn’t stop Toni Sleugh from turning her ISU experience into exactly what she wanted in terms of marine biology, environmental conservation and management. Sleugh will graduate this weekend with a bachelor’s degree in biology and environmental studies before heading to a Ph.D. program.

  • Player to engineer: Iowa State senior turns computer game passion into career

    Jamie Sampson’s childhood love of computer games like SuperTux, Zoombinis and JumpStart has grown into a career. After graduating from Iowa State this weekend with a degree in software engineering, she'll head to a job at a studio division of Electronic Arts, one of the leading video game companies.

  • COVID-19 weekly snapshot

    The following information is a supplement to the university's COVID-19 Public Health Data weekly updates. It is intended to provide a brief snapshot of the data and trends identified by Iowa State's public health team.
