Jill Johnson Publishes Paper on Heat Shock Proteins in Nature Communications
Professor Jill Johnson, in collaboration with researchers at the University of Alberta and the University of Würzburg, recently published a paper in Nature Communications titled: “The conserved NxNNWHW Motif in Aha1-type co-chaperones modulates the kinetics of Hsp90 ATPase stimulation and is essential for in vivo function.” This research seeks to understand how Hsp90 partners with interacting cochaperones to help 10-15% of cellular proteins fold properly. As part of an IBEST pilot grant award to Dr. Johnson, she identified a version of Hsp90 that increases the requirement for specific cochaperones, allowing more detailed analysis of their function. Hsp90 binds and hydrolyzes ATP, but the link between this activity and function remains unclear. This work suggests that one type of cochaperone regulates a critical step that occurs after ATP hydrolysis. Future collaborative efforts will lead to a greater understanding of Hsp90 function, with the eventual goal of learning how changes in nucleotide release affect the ability of Hsp90 to interact with misfolded proteins.Full Story

Diana Mitchell and the GRC published in Scientific Reports - Nature
Assistant Professor Diana Mitchell, in collaboration with Professor Deb Stenkamp of the Dept. of Biological Sciences and the IBEST GRC, recently published a paper in the Scientific Reports - Nature journal titled: “Regeneration associated transcriptional signature of retinal microglia and macrophages.” Funding for this work was provided by Idaho INBRE through a Technology Access Grant awarded to Dr. Mitchell and an NIH R21 awarded to Dr. Stenkamp. Their research seeks to understand the remarkable capacity in which zebrafish can regenerate retinal neurons, in this case with a focus on immune cell populations present during retinal repair. This manuscript is the first work of its kind to use RNA sequencing to probe macrophage populations isolated from tissue in a regenerative state. This work has increased the knowledge of macrophage functions during zebrafish retinal regeneration and provides a wealth of candidate pathways towards understanding macrophage functions in this context.Full Story

Dept of Fish and Wildlife Sciences Researcher Ryan Long Published in Science
Assistant Professor Ryan Long from the Department of Fish and Wildlife Sciences published in Science. Working in Gorongosa National Park, Mozambique, Long and his colleagues found that bushbuck, a forest-dwelling antelope, began to graze the plains after the country's civil war exterminated large predators. In a domino effect, this change in bushbuck foraging behavior altered plant growth on the plain. However, when the researchers mimicked the smell and sounds of predators, bushbuck reversed this behavior, suggesting that the effects of human-caused extermination of big predators can also be reversed if predators are restored.Full Story

Polymorphic Games Releases Newest Game, Project Hastur
Polymorphic Games has just released their newest game "Project Hastur" on Steam in honor of #DarwinDay. PROJECT HASTUR creates a unique challenge by combining elements of 3D tower defense and real-time strategy with biological evolution. Fight against alien Proteans that evolve - using biologically accurate models of evolution - to overcome the player’s defenses. Each creature you will face has its own unique genome controlling its abilities, behaviors, and appearance. Those that make it the furthest and do the most damage to your defenses have the most offspring you will have to defeat in the next generation. The result? Evolution responds to the player’s strategy and makes every playthrough a unique experience.Buy the Game

U of I Researchers Investigate the Snail Rainbow
Department of Biological Sciences' Christine Parent, Andrew Kraemer, and BCB student Andrew Rankin published a paper on Galápagos snails in the Proceedings of The Royal Society B. They found mockingbirds were less likely to feed on snails that matched the color of their backgrounds than conspicuous snails. They think this food selection process may have led to the variation in snail color across the island chain. In addition, it seems the snails in the sunniest locations have evolved to reflect more light than shade-dwelling snails, an adaptation that would help them avoid overheating.Full Story
IBEST Researchers Create New Method to Study Viruses in Fungi
Department of Biological Sciences' Paul Rowley, Angela Crabtree, Emily Kizer and James Van Leuven, as well as Samuel Hunter, Daniel New and Matthew Fagnan with the Institute for Bioinformatics and Evolutionary Studies (IBEST) Genomics Resources Core published a study in the journal Viruses. Brewer's and Baker's yeast play host to many viruses that have genomes made of double-stranded RNA. This type of genetic material is labor-intensive and time-consuming to analyze. The team created a new method to purify and sequence the double-stranded RNAs of two mycoviruses in yeast. They discovered new mutations in the RNA that increased the toxicity of an antifungal drug produced by yeast.Full Story

Cameron Perry: Animating a Hero
At age 6, Cameron Perry began playing a video game that featured a world undergoing industrialization. The consequences were environmental degradation and the exploitation of labor. Perry didn’t understand the themes at the time. He was more concerned with helping his character escape a meat packing plant and join a band of revolutionaries. Over time, the game’s motif started to sink in. “There’s plenty of issues in fiction where you have a prominent social issue and it’s an analog for what’s going on in the real world,” said Perry, a virtual technology and design student graduating in fall 2018 from the University of Idaho College of Art and Architecture. “Abstracting things like that lets us examine social issues that might otherwise be uncomfortable.” Perry worked for Polymorphic Games at U of I and created animations for Project Hastur, a video game where users try to protect humanity from invading aliens that evolve in response to users’ defenses. He also worked for the university’s Institute for Bioinformatics and Evolutionary Studies, designing a mobile app prototype to teach kids about snail biology, evolution and conservation. A native of Boise and Bonners Ferry, Perry, 26, already has a job lined up creating virtual reality environments as a more engaging and less costly aid for workplace training. Someday, though, Perry would like to return to the realm of video games, creating “oppressive worlds that people are fighting back against.”UIdaho Story

U of I Study Predicts Increase in Global List of Threatened Plant Species
MOSCOW, Idaho — Dec. 3, 2018 — More than 15,000 plant species have a high probability of being considered threatened or near-threatened under a new model used to predict conservation status. The model, which shows the predicted levels of risk to plants worldwide, was published as part of a study to help governments and resource managers evaluate where conservation resources are most needed. Findings from the model, built by a research team from the University of Idaho, University of Maryland, Radford University and The Ohio State University, were published today in the Proceedings of the National Academy of Sciences. The International Union for Conservation of Nature’s (IUCN) Red List of Threatened Species is a powerful tool for researchers and policymakers working to limit species loss across the globe. A new approach developed at U of I and The Ohio State University uses the power of machine learning and open-access data to predict plant species that could be eligible for at-risk status on the IUCN Red List. Adding even a single species to IUCN’s Red List demands hours of expensive, rigorous and highly specialized research. As a result, many known species have not been formally assessed by the IUCN and ranked from least concern to critically endangered; only about 5 percent of all currently known plant species appear on IUCN’s Red List in any capacity. The research team created and trained a machine learning algorithm to assess more than 150,000 species of plants from all corners of the world, making their project among the largest assessments of conservation risk to date. The researchers trained the model using open-access data from the relatively small group of plant species already on the IUCN Red List, and then applied the model to the many thousands of plant species that remain unlisted by IUCN. “Our method isn’t meant to replace formal assessments using IUCN protocols. It’s a tool that can help prioritize the process, by calculating the probability that a given species is at risk,” said Anahí Espíndola, who worked on the project as a U of I postdoctoral researcher and now is an assistant professor at the University of Maryland. “Ultimately, we hope it will help governments and resource managers decide where to devote their limited resources for conservation. This could be especially useful in regions that are understudied.” The model predicted roughly 10 percent of the total plants assessed by the team have a high probability of qualifying as near-threatened or worse. Maps of the data indicate at-risk species tend to cluster in areas already known for their high native biodiversity, such as the Central American rainforests and southwestern Australia. The model also flagged regions such as California and the Southeastern United States, which are home to a large number of endemic species not naturally occurring anywhere else on Earth. “Although our primary goal was to help prioritize the process for ranking species, identifying geographic areas with high concentrations of potentially at-risk species was an added bonus,” said David Tank, associate professor in U of I’s Department of Biological Sciences. The model also flagged a few surprising areas not typically known for their biodiversity, such as the southern coast of the Arabian Peninsula, as having a high number of at-risk species, according to the study. Some of the most imperiled regions have not received enough attention from researchers, Espíndola said. She hopes the study method can help to fill in some of these knowledge gaps by identifying regions and species in need of further study. “We’re in an era in which large-scale public databases contain massive amounts of information,” said Jack Sullivan, a professor in U of I’s Department of Biological Sciences. “This paper demonstrates that machine learning approaches can yield important conclusions in biodiversity studies by detecting signals and patterns in big data.” Media note: An image associated with the study’s findings is attached to the press release.
