Engineers study icing/de-icing of wind turbine blades to improve winter power production
A research group led by Iowa State's Hui Hu will use the university's Icing Research Tunnel to study icing of wind turbine blades. Studies have shown that ice accumulation on turbine blades can reduce power production by up to 50%. The team will also study ways to prevent or delay ice formation on the blades. A grant from the Iowa Energy Center is supporting the project.

Brewed coffee grounds offer sustainable alternative for clothing dye
Iowa State University researchers have found a natural way to add color to clothing using the leftover grounds from your daily cup of coffee. The textile industry uses more than 2 million tons of chemicals and synthetic dyes annually, which is why researchers are interested in finding sustainable alternatives.

Machine learning in agriculture: ISU scientists are teaching computers to diagnose soybean stress
Machine learning could lead to automated processes that would allow soybean producers to diagnose crop stresses more efficiently. A multi-disciplinary team at Iowa State University recently received a grant to develop the technology, which could lead to unmanned aerial vehicles surveying fields and automatically analyzing crop images.

Chasing storm data: machine learning looks for useful data in U.S. thunderstorm reports
Iowa State researchers are using machine-learning tools to clean up thunderstorm reports compiled by the National Weather Service. The goal is to determine which reports accurately describe storms that had winds greater than 58 mph. Accurate wind data could lead to new tools that predict the likelihood a thunderstorm will produce severe winds.

Maturity becomes a concern as harvest approaches
Iowans may notice combines harvesting corn deep into November due to the late start to planting last spring, according to Iowa State University agronomists. Much of the Iowa corn crop remains weeks behind schedule, and farmers will be paying close attention to temperature as their crop nears maturity and dries down.

New study suggests U.S. land carbon sink may have been overestimated
A new study could help scientists better understand how changes in land use affect carbon, a critical element in some greenhouse gases. Previous models may have overestimated cropland abandonment and reforestation in the United States, according to the study, which used higher resolution land-use data to drive carbon budget models.

Midwest schools join forces to promote faculty success for women in STEM fields
Researchers from four Midwestern research universities -- including Iowa State -- are joining forces to promote faculty success in science, technology, engineering and math fields for women of color and women with family responsibilities. Their project is supported by a three-year, $996,000 grant from the National Science Foundation.
