Delivery demand driving pressure on urban freight capacity

More people are living and working in downtown or urban neighborhoods, which is increasing demand for urban deliveries. An Iowa State University researcher says we can expect more congestion and pollution as a result. That is why Johanna Amaya Leal and a team of researchers are looking for solutions.

Yield tests prepare for 100th year of helping farmers decide what seeds to plant

With the publication of this year’s Iowa Crop Performance Tests results this month, the program is preparing to launch its 100th year in 2019. The Iowa Crop Performance Tests take place on ISU research farms and cooperating private farms across the state. They gauge the performance of roughly 200 varieties of corn and soybeans to help farmers make informed decisions on what seeds to plant.


Sketchnoting pushes students to learn, retain information differently – particularly in STEM

Over the last three years, sketchnoting has been introduced to about 1,000 students, faculty and staff across a wide range of disciplines at Iowa State University. This fall, an interdisciplinary research team is studying how this alternative to traditional note-taking affects learning.

Farmland expansion increases carbon footprint in Corn Belt, according to Iowa State University research

A new study led by an Iowa State University scientist shows that increases in crop production due to expanding acreage devoted to agriculture in five Midwestern states between 2006 and 2016 has reduced the region’s soil carbon content. The reduced carbon storage capacity means that some carbon that once resided in the soil and plant life is released into the atmosphere instead.

Lack of sleep intensifies anger, impairs adaptation to frustrating circumstances

Losing just a couple hours of sleep at night makes you angrier, especially in frustrating situations, according to new Iowa State University research. While the results may seem intuitive, the study is one of the first to provide evidence that sleep loss causes anger. The research also provides new insight on our ability to adjust to irritating conditions when tired.
