Edwards Elementary students perform maker theater

‘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.

Tallgrass prairie

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.

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.
