Engineers develop placenta-on-a-chip to study caffeine transport from mother to fetus

Iowa State's Nicole Hashemi has used her expertise in microfluidics to lead development of a device that models a human placenta. She and her research team have used the "placenta-on-a-chip" to study transport of caffeine from the mother, across the placental barrier, to the fetus. The journal Global Challenges has just published a paper describing the device and reporting on the caffeine study.

David Peters, associate professor of rural sociology, expects in the next two to three years the state will see an uptick in overdose deaths from heroin and synthetic opioids, such as fentanyl.

Data mining brings new clarity to plant breeding, according to new Iowa State University study

Data mining methods that draw on computer science and statistics can bring new clarity for plant scientists trying to design better crop varieties, according to newly published research from an ISU agronomist. The study outlines several data management approaches that can help plant breeders predict the traits of potential hybrids faster and cheaper than growing and testing the plants.
