Engineers developing data-driven ‘FactBoard’ to improve factory operations
Iowa State's Guiping Hu is leading a research team developing data-driven, real-time software technology to help improve factory floor operations, including manufacturing processes, logistics, safety and energy management. The $2.6 million project is supported, in part, by the Digital Manufacturing and Design Innovation Institute and several industry collaborators.
Consumers may not recognize costs, consequences of demand for ‘clean’ food
Eating “clean” is all about avoiding foods with additives, preservatives or other chemicals on the label, but two Iowa State University professors are warning of the consequences in terms of food waste, safety and cost.
Change Agent: Julie Stevens
Over the past six years, Julie Stevens, her landscape architecture students and the women at Iowa Correctional Institution for Women have transformed the facility’s barren 30 acres into a living landscape of trees, native prairie, vegetables, flowers, butterflies and bunnies. There are outdoor classrooms for learning, quiet spaces for reflecting and fresh produce for eating.
ISU researchers receive $1 million grant to advance organic corn genetics
A $1 million grant will help ISU researchers advance the genetics of corn varieties intended to be grown in organic settings. The project aims to improve the performance of field and sweet corn varieties in conditions unique to organic production systems.
Shift needed in understanding risk in play environments
Since the 1960s, there has been a trend in the United States to eliminate the risk from play environments. Teeter-totters, merry-go-rounds and monkey bars were deemed too dangerous. But danger is not the same as risk. And eliminating all risk within play eliminates creativity, challenge and discovery, says Bambi Yost, associate professor of landscape architecture at Iowa State University. She is one of an increasing number of researchers who agree that safe, risk-taking opportunities on the playground can benefit children's health and learning.
Tom Vilsack will speak on ag and climate change Nov. 16 at ISU
Former Secretary of Agriculture Tom Vilsack will discuss how a changing climate threatens the agriculture industry in a talk at Iowa State. “Agriculture and Climate Change” will be at 7 p.m. Thursday, Nov. 16, in the Memorial Union Great Hall. Vilsack is president and CEO of the U.S. Dairy Export Council. He served as agriculture secretary for eight years in the Obama administration, and was Iowa's governor from 1999 to 2007.

Ordinance reduces violent crime near late-night bars by making owners part of solution
An ordinance requiring bar owners to beef up security helped reduce violent crime in and around late-night clubs in Little Rock, Arkansas, according to a new study led by an Iowa State University researcher. Kyle Burgason says other cities tackling crime near bars and nightclubs could take similar action with the same results.
Iowa State engineers help Black Sea countries fight cybersecurity threats
Iowa State University cybersecurity researchers recently presented two days of demonstrations and case studies to help four Black Sea countries fight off cyberattacks. Some 230,000 people in one of those countries -- Ukraine -- were left without electricity in December 2015 after a cyberattack took down dozens of power substations. The demonstrations at Iowa State were part of a study tour sponsored by the U.S. Agency for International Development and organized by the National Association of Regulatory Utility Commissioners.
Wendy Wintersteen named Iowa State University president
Wendy Wintersteen's appointment concludes a nearly six-month national search for Iowa State's 16th president. Wintersteen will take office on Nov. 20, succeeding Benjamin Allen, who has served as interim president since May 8. Wintersteen led the ISU College of Agriculture and Life Sciences from 2006 until her selection as university president.
Teens sacrifice sleep when they spend more time on electronic devices
The temptation to respond to social media notifications and text messages from friends is keeping more and more teens awake at night. New research from Iowa State and San Diego State universities found teens who spend more than two hours a day on their smartphones get fewer than seven hours of sleep each night.
You would not ask a firefighter to perform open-heart surgery
The concept of “collective intelligence” is simple – it asserts that if a team performs well on one task, it will repeat that success on other projects, regardless of the scope or focus of the work. While it sounds good in theory, it doesn’t work that way in reality, according to an Iowa State University researcher.
‘Maker theater’ puts the spotlight on geometry and literacy
Third graders at Edwards Elementary School combined lessons in literacy and geometry to stage a theater with sets and scripts developed with the help of Iowa State University students. Geometry and literacy were not the only lessons students gained from the experience.
Iowa State astronomer says star dust helps explain mysterious dimming star
Iowa State's Massimo Marengo is part of a team of astronomers working to understand the mysterious dimming of Tabby's Star. The star was found by citizen scientists who noticed unprecedented dips in the star's brightness. The unusual dimming led to a lot of potential explanations, including speculation that alien megastructures built to harvest the star’s energy were passing in front of the star. The astronomers report that space dust orbiting the star is the likely cause of the star's long-term dimming.
Fertilizers adjust nitrogen cycle of prairie plants, according to Iowa State University study
Excess nitrogen can change the composition of tallgrass prairies, granting an advantage to plants that flower earlier in the growing season over plants that flower later, according to new research from an Iowa State University scientist. The findings have implications for wildlife and pollinating insects that use prairie plants for habitat.
Iowa State University researcher finds further evidence that fats and oils help to unlock full nutritional benefits of veggies
Some dressing with your greens may help you absorb more nutrients, according to a study from an Iowa State University scientist. The research found enhanced absorption of multiple fat-soluble vitamins in addition to beta-carotene and three other carotenoids. The study appeared recently in the peer-reviewed American Journal of Clinical Nutrition, and the results may ease the guilt of countless dieters who fret about adding dressing to their salads.
