Study of ‘shrink-smart’ towns expanding to include curriculum, big data
Iowa State's rural smart shrinkage project has received a three-year, $1.5 million grant from the National Science Foundation to build upon its pilot study examining whether there were towns in Iowa that have lost population but perception of quality of life has remained stable or improved.
Iowa State fall enrollment of 31,825 shows strong retention
Iowa State’s fall enrollment of 31,825 students includes a diverse and academically strong class of 5,071 first-year students with a record GPA of 3.71 and 17.2% U.S. multicultural students. The university's one-year retention rate also set a record this fall with 88.5% of first-year students returning for a second year.
New study on migration success reinforces need for monarch butterfly milkweed habitat
A recently published study presents evidence that the migration success of monarchs hasn’t declined in recent years and thus cannot explain the steep decline in the monarch population over the last few decades. The study drew on data collected on 1.4 million monarch butterflies that were tagged in the United States Midwest from 1998 to 2015 and emphasizes the need for new monarch habitat.
A derecho debrief: Not even a scientist/storm chaser expected the August 10 storm
Bill Gallus, an Iowa State storm expert (and chaser), was as surprised as anybody by the Aug. 10 derecho that blew across Iowa and the Midwest. He expects researchers will take a good look at why the violent, straight-line winds didn't show up in forecasts. And does a warmer climate mean more of these storms are coming? Gallus said it's hard to say for several reasons, including the fact there are too few of the storms to establish much of a trend line.
Iowa State to open new COVID-19 testing center
Iowa State University is expanding its COVID-19 testing, case management and contact tracing efforts to manage infection on campus. A new testing center will open in the next week in Johnny’s at Hilton Coliseum, and the university is more than doubling the number of contact tracers and case managers who notify and support ISU students, faculty and staff who test positive or were potentially exposed to a positive COVID-19 case.
Engineers use heat-free technology to make metallic replicas of a rose's surface texture
Iowa State's Martin Thuo and his research group have developed technology to make metallic replicas of soft, natural surfaces such as rose petals. The team's metallic surfaces retained properties of the originals, including a rose petal's sticky, yet water-repelling textures.
Plant scientists study the interaction of heat stress responses in corn
A new study shows how two responses in separate locations inside plant cells work in concert to help corn plants respond to heat stress. The research was made possible by the Enviratron, an innovative plant sciences facility at Iowa State University that utilizes a robotic rover and highly controlled growth chambers.
COVID-19 cases reported for first week of classes
Iowa State University will provide weekly updates on COVID-19 test results. The data will include testing conducted at Thielen Student Health Center (TSHC) for students, faculty and staff who were symptomatic or exposed to someone who tested positive, as well as test results from the athletic department.
Flexibility key as Iowa State begins fall semester during ongoing pandemic
As the fall semester at Iowa State University gets underway, faculty and graduate students discuss the new mix of face-to-face, hybrid and online courses in place due to the ongoing COVID-19 pandemic.
Final update on move-in COVID-19 testing
The final days of move-in testing at Lied Recreation Center wrapped up on Sunday. For the two weeks of COVID-19 testing, 8,094 students living in the residence halls and campus apartments were tested and 175, or 2.2%, tested positive, and 7,919, or 97.8%, tested negative.
Biomedical scientists piece together how medication paralyzes parasitic worms
A new study upends the widely held belief that a medication used to treat lymphatic filariasis doesn’t directly target the parasites that cause the disease. The research shows the medication, diethylcarbamazine, temporarily paralyzes the parasites.
Update on COVID-19 testing at Iowa State
From Aug. 7-13, 3,472 Iowa State University students moving into the residence halls and campus apartments completed COVID-19 testing at Lied Recreation Center. Of that number 75 students, or 2.2%, tested positive, and 3,397 students, or 97.8%, tested negative.
Book examines influence of racism on voting rights
There is greater awareness today of structural racism in the U.S., but Americans are still split on the impact it has on the voting rights of underrepresented groups, according to a new book co-authored by an Iowa State University political scientist. The book, “Ignored Racism” examines the history of hostility toward Latinos and how it influences attitudes about voting rights.
Searching the ancient depths of a reptilian genome yields insight into all vertebrates
An Iowa State University scientists contributed to a global effort to assemble the genome of the tuatara, a rare reptile species native to New Zealand. The tuatara genome sheds light on the genomic structure of a huge range of species, including humans.
