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.

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.

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.

Iowa State students begin moving into the residence halls
New students are starting to move into the residence halls at Iowa State University. The move-in process for fall is starting earlier than usual and spread out over a longer period of time to help maintain physical distancing in the residence halls. Approximately 9,300 students will move in to campus housing over the next two weeks. They are required to complete a COVID-19 test prior to move-in.

Anti-Asian racism during COVID-19 has historical ties in United States
Anti-Asian hate crimes during health crises are unfortunately not new, according to a new academic paper examining the history of this phenomenon. The research team, including an Iowa State University criminal justice researcher, looked at how anti-Asian hate crimes during the COVID-19 pandemic have furthered the historical “othering” of Asian Americans and reproduced inequalities.

Engineers find thinner tissues in replacement heart valves create problematic flutter
Iowa State and University of Texas engineers have developed high-fidelity computational models of replacement heart valves to examine the performance of biological tissues built into the valves. They found that thinner tissues can flap and flutter, which can damage the valves and even the blood that flows by.

Iowa State University scientists examine reproductive effects of glyphosate in mice
A pair of recently published studies analyzed how ovarian function in mice responded to various levels of exposure to glyphosate, a chemical extensively used to kill weeds. The results showed exposure changed the level of some ovarian proteins but did not impact ovarian steroid production, an indication glyphosate may not adversely affect reproduction.
