  • Now that the Webb Space Telescope is deployed (whew!), astronomers wait for data

    Iowa State's Massimo Marengo is ready to use the newly launched James Webb Space Telescope to study distant clouds of dust in a galaxy with a "primitive environment" that resembles the conditions of the early universe. Webb's data will help Marengo and his colleagues understand the "galactic ecosystem" and the early steps in "the cycle of life of the universe."

  • Unraveling the connections between singing and Parkinson’s disease

    ISU researchers are embarking on an in-depth and comprehensive study to determine the underlying mechanisms by which singing can improve breathing and swallowing for people with Parkinson’s disease. The researchers will also track changes to brain activity and biomarkers of stress and inflammation to better understand how the social benefits of singing with others can slow the disease’s progression and its symptoms.

  • Computer models show how crop production increases soil nitrous oxide emissions

    Computer models designed by Iowa State University scientists show how the emissions of the greenhouse gas nitrous oxide have increased from soils over the last century. The newly published research found the expansion of land devoted to agriculture since 1900 and intensive fertilizer inputs have predominantly driven an overall increase in nitrous oxide emissions from U.S. soils.

  • How providers help patients shift expectations to make tough medical decisions

    A new study explores how specialized care providers navigate conversations with patients and their families about switching from curative treatments to pain management and comfort care. Many of the providers did not dismiss their patients’ emotions or tell patients to feel differently. Rather, they validated their patients’ fear, hope or guilt, and then walked them through the likely outcomes of continuing treatments.

  • Exercise post-vaccine bumps up antibodies

    Participants in the study who cycled on a stationary bike or took a brisk walk for an hour-and-a-half after getting a flu shot or COVID-19 jab produced more antibodies in the following four weeks compared to participants who sat or continued with their daily routine post-immunization.

  • Ames, ISU police share results of traffic stop study

    An independent review found “negligible evidence of racial bias” by Ames and Iowa State University police officers when initiating traffic stops. The departments requested the review as a proactive step to evaluate whether or not racial disparities existed in traffic stops and the outcomes.

  • Mosquito surveillance program finds invasive species taking root in three Iowa counties

    An invasive species of mosquito has established itself in three Iowa counties, according to data from Iowa State University entomologists. The species is capable of transmitting disease, but ISU experts said the species’ arrival is no cause for alarm.

  • Iowa State partners with U.S. State Department on global historic preservation projects

    Iowa State is the only university in the United States to have a partnership with the U.S. Department of State to work on historic preservation projects at U.S. diplomatic properties around the world.

  • Eye tracking reveals where people look during Zoom, Webex

    An innovative, first-of-its-kind study used eye-tracking technology to explore what people look at during virtual meetings, finding participants looked offscreen more often during smaller, interactive sessions and that women looked at their own video more than men. This and future research may help inform the future design of videoconferencing.

  • Scientists take major step in understanding domestication of corn

    Iowa State University scientists have harnessed gene editing to peer back through thousands of years of domestication to learn about teosinte, the wild ancestor of modern corn. The research allows for genetic comparisons and could lead to more resilient crops.

  • Black History Month to be celebrated at Iowa State

    A variety of events are planned to celebrate Black History Month throughout February at Iowa State University and in Ames.

  • Change Agent: Martin Thuo, materials science and engineering

    Martin Thuo and his research group have developed heat-free solder. They’ve printed electronics on rose petals. They’ve made “chameleon metals” that change surfaces in response to heat. With a bit of “metal whispering,” they’ve found a better way to recover precious metals from electronic waste. And now, after two and a half years of work, they’ve invented a new seed lubricant. What’s the source of that creativity?

  • ISU program aims to support healthy aging through walking

    Researchers at Iowa State University are studying how adding personalized health coaches, training modules and accountability reminders to an evidence-based walking program can help seniors incorporate more steps into their daily lives. The researchers’ ongoing virtual format and the re-launch of their in-person programming this month aims to support healthy aging across Iowa.

  • World’s largest science society honors six Iowa State researchers for distinguished work

    Iowa State University's latest class of AAAS Fellows includes four biologists, a statistician and a physicist. The American Association for the Advancement of Science said the fellows are being recognized "because of their efforts to advance science applications that are deemed scientifically or socially distinguished."

  • Finding a link between emissions taxes and R&D investments

    After analyzing roughly 33,500 manufacturing firms across 18 countries, researchers found a strong, clear link between high emissions taxes and substantial investments in research and development.

  • Under the hood: How environment and genomes interact in plant development

    A new study from Iowa State University scientists could help to breed more resilient crops as well as shed light on mechanisms that play a critical role in plant growth. The study focuses on how phenotypic plasticity, or the way a given trait can differ as a result of environmental conditions, influences the growth of sorghum.

  • The cellular response that protects pigs from COVID-19

    Studies since the start of the pandemic have noted that pigs exposed to the coronavirus don’t show clinical signs of disease nor do they transmit the virus to other animals. Iowa State University scientists have uncovered important clues that shed light on why pigs don’t get sick, and the discovery could lead to better treatments for COVID-19 in humans.
