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.

Researchers demonstrate engineering approach to combine drugs, control parasitic worms
Iowa State University's Santosh Pandey helped lead a project that demonstrates an engineering technology used in cell studies can also be used for drug testing on parasitic roundworms used as a model whole organism. In this case, the technology quickly developed a cocktail of four drugs that was effective in paralyzing the roundworms. The discovery is reported in the journal Science Advances.
Iowa State University project: Prairie strips yield big environmental benefits
The ISU Prairie STRIPS project has found the strategic use of native prairie plants among agricultural fields yields a wide range of environmental benefits, including erosion and runoff reduction and increased wildlife habitat. The findings, published this week, draw on 10 years of data and cover dozens of environmental metrics.

Bovine embryo transfer helps ISU veterinarians improve herd genetics
Iowa State’s College of Veterinary Medicine offers students and current veterinarians opportunities to get hands-on experience with bovine embryo transfer, a growing practice that helps cattle producers pass on desirable genetics to more calves. But it requires a trained eye.
School, health and behavior suffer when children have TV, video games in bedroom
A new Iowa State University study is one of the first to demonstrate the consequences of allowing children to have a TV or video game system in their bedroom. Researchers found children spent less time reading, sleeping or participating in other activities when they could go in their room and watch TV or play video games. As a result, they did not do as well in school and were at greater risk for obesity and video game addiction.
80th anniversary of massacre time for remembrance and recognition of solidarity
October marks the 80th anniversary of the 1937 Haitian massacre, which killed an estimated 20,000 Haitians and Dominicans of Haitian descent. Megan Jeanette Myers says the anniversary is a time for reflection and recognition. The ISU assistant professor is a co-founder of Border of Lights, an organization that provides support to border communities and commemorates the lives lost in the massacre.
