They've formulated the "inverse chirp z-transform," an algorithm related to one that's running on your cell phone right now. It took some computing power and some math expertise to do it.

<![CDATA[Bad behavior between moms driven by stereotypes, judgment]]> http://www.news.iastate.edu/news/2019/10/09/momwars 2445A Mothers are often their own toughest critics, but new research shows they judge other mothers just as harshly. According to the results, ideal and lazy mothers drew the most contempt from both working and stay-at-home mothers. The overworked stay-at-home mom also was near the top of the list.

<![CDATA[Ambitious strategies to combat pests and disease in organic agriculture]]> http://www.news.iastate.edu/news/2019/10/08/organicpestmanagement 2446A Iowa State University researchers have received a grant to look at innovative ways that allow organic fruit and vegetable growers to combat pests, weeds and disease. Much of the research centers on mestotunnels, or material used to create a physical barrier to protect plants from certain pests. The practices to be analyzed could help organic growers with management challenges without the use of conventional pesticides.

<![CDATA[Corn and soybean rotation could pose long-term tradeoffs for soil health]]> http://www.news.iastate.edu/news/2019/10/02/croprotation 2438A A new study examines the mechanisms that drive the decomposition of organic matter in soils that undergo long-term corn and soybean crop rotations. The study shows how corn and soybean rotations can provide important environmental and management benefits for farmers, but the practice also comes with tradeoffs that some farmers may wish to address by adjusting their management practices.

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.
