As cancer cells divide uncontrollably nutrients from nearby tissue – specifically the amino acid glutamine – are depleted. Glutamine is one of the most abundant amino acids in the bloodstream, and most cells cannot live without it. Tumors have poor vasculature which further contributes to the depletion of nutrients. Even in nutrient-depleted environments, tumors have found ways to grow.Tumors are comprised of cancer cells as well as non-cancerous stromal cells. Studies have shown stromal cells can synthesize glutamine which they release into the tumor microenvironment feeding cancer cells and allowing them to grow. However, the signaling pathway used between the cancer and stromal cells in this relationship remains unclear.To study the signaling pathway by which stromal cells are synthesizing glutamine I treated cells with a common anti-inflammatory drug, dexamethasone. Mice receiving dexamethasone over a long period of time had increased lung metastases when injected with cancer cells. Dexamethasone binds to the glucocorticoid receptor (GR) which activates the expression of glutamine synthetase (GLUL) enzyme mRNA. The expression of GLUL causes the cell to synthesize glutamine. However, the role of GR, in regulating GLUL expression in tumors, remains insufficiently studied.The experiments done for this project show that dexamethasone induces GLUL expression in stromal cells such that they start releasing glutamine. This may promote growth of cancer cells even when there is a deficit of nutrients around. It is hypothesized that due to this property, dexamethasone increases risk of metastasis. This project will aid in the development of cancer therapeutics to treat metastatic cancers.

Tissue-resident macrophages play critical roles in tissue homeostasis and immunity, and many of them have a distinct fetal origin and developmental trajectory as compared to their adult bone marrow-derived counterparts. However, the specific mechanisms underlying their developmental signaling pathways have not been as thoroughly examined as in the adult. Our lab recently demonstrated that fetal-derived macrophage development is regulated by expression of the lymphoid-associated interleukin-7 receptor (IL-7R) in mice, but the fetal source of the cognate cytokine ligand, interleukin-7 (IL-7), has yet to be determined. This project investigated fetal macrophage cells as a potential source of IL-7 production, with the aim of providing further insight into these signaling pathways during prenatal development. A transgenic mouse model was used that expresses IL-7 attached to green fluorescent protein (GFP) in order to measure GFP expression as a proxy for IL-7 expression in developing tissues. Embryonic tissues were extracted from mouse fetuses at 17.5 days post-conception and cells were isolated and stained with antibodies to identify blood, endothelial, and stromal cells as putative sources of IL-7 production. Samples were also intracellularly stained for GFP in order to quantify the IL-7 production across different cell types within different tissues in the embryo. The resulting data preliminarily identifies fetal macrophages as the primary producers of IL-7 across common tissues in the developing embryo. A better understanding of the developmental signaling pathways that regulate fetal immune development can expand comprehension of the origins of early immune dysfunction and help mitigate disease susceptibility from early life.

Authors: Amber Brooks. Mentors: Michelle Schober. Insitution: University of Utah. Traumatic brain injury (TBI) can cause death or result in long-term disabilities. TBIs are the leading cause of death and disability due to trauma and the leading cause of acquired neurological disability in children. At present, medical treatment using supportive and specific therapies to optimize recovery are lacking. Docosahexaenoic acid (DHA), a component of fish oil and a natural constituent of brain cell membranes, is a potential candidate therapy to improve neurologic recovery after severe TBI. The objective of our project is to test the hypothesis that DHA improves cognitive outcome and brain imaging in a male rat model of pediatric TBI, controlled cortical impact (CCI) in male rat pups. Seventeen-day-old male rat pups received CCI or a minimally invasive (SHAM) surgery. Half of the CCI and SHAM rats were fed a DHA diet for 60 days before experiments began. Learning was tested using a Morris Water Maze (MWM) experiment and memory was tested using a Novel Object Recognition (NOR) experiment. Brain injury assessment was accomplished using T2 and DTI magnetic resonance imaging (MRI). The T2 MRI scans were used to measure the volume of the hippocampus, the center for learning and memory, and to lesion volume, to assess loss of hemisphere volume. The DTI MRI scans were used to observe the injury to the white matter of the brain. Based on preliminary findings, we anticipate that the results of the study will not support our hypothesis and that DHA will have no beneficial effects on improving cognitive outcomes and brain imaging.

Climbing is now an Olympic sport and thus the demand for understanding performance predictors to train with evidence has grown enormously. Previous climbing research has highlighted that finger strength and shoulder strength are important predictors of performance between lower level and higher level climbers. However, no study has examined the rate of force development in the upper body, and lower body strength also has not be assessed in climbing literature. PURPOSE: To determine if relationships exist between dominant and non-dominant finger RFD compared to dominant and non-dominant finger and shoulder strength as well as lower body strength. METHODS: Twenty subjects (n=8 female and n=12 male; age: 24.7±7.5 yrs; height: 177.6±7.8 cm; mass: 76.0±14.9 kg; IRCRA Sport Grade: 14.1±6.7; n=11 beginner/intermediate, n=9 advanced) completed this study. During a single session, following a standardized 3-5 min. warm-up all participants dominant and non-dominant finger strength and RFD (using a Tindeq dynamometer load cell attached via static rope to a 20mm edge) as well as shoulder strength (using the same Tindeq load cell with a static rope and olympic ring), and lower-body compound strength (isometric mid-thigh pull using G-strength dynamometer load cell attached to a straight bar with a static rope) were assessed. Three trials were done on each measurement with 1 min. between trials and 3-5 min. between tests. Pearson correlational analyses were done to determine correlation coefficients (r), with significance set at p<0.05. RESULTS: Both dominant and non-dominant RFD resulted in significant (p<0.05) large to very large positive relationships with dominant finger strength (r = 0.897 and 0.721, respectively), non-dominant finger strength (r = 0.913 and 0.757), dominant shoulder strength (r = 0.670 and 0.709), on-dominant shoulder strength (r = 0.724 and 0.744), and lower body compound strength (r = 0.645 and 0.653). CONCLUSION: Dominant and non-dominant RFD is positively related to upper and lower body strength in recreational to advanced climbers. Therefore, training finger RFD and lower body strength should be consider as important as developing finger and shoulder strength in recreational to advanced climbers.

Authors: Addison Hedges, Kevin Sattler. Mentors: Moriel Zelikowsky. Insitution: University of Utah. Trauma has been reported to affect over 70% of all adults worldwide. This includes, but is not limited to, physical and sexual violence, injury, threat of death, and natural disasters. Experiencing one or more traumatic events can lead to post-traumatic stress disorder, depression, and anxiety. These symptoms and disorders can negatively affect interpersonal relationships, confidence, aggression, and other aspects of daily behavior. Exactly how these traumatic events are encoded in the brain is poorly understood. Extensive research has been done on the hippocampus with regard to its central role in learning and memory, but only recently has research been done to uncover its role in emotional responses. This research has found distinct functional differences between the dorsal and ventral subregions of the hippocampus. Recent studies suggest that the ventral hippocampus (VH) plays an important role in emotional response. The VH projects to other emotional processing areas of the brain that modulate fear, aggression, and social processing. This project aims to test the hypothesis that distinct populations of neurons in the VH encode individual behavioral effects of trauma as well as discover the extent of overlap between neuronal cells activated by trauma-induced aggression (TIA) vs. trauma-altered sociability (TAS). To test this hypothesis, both male and female mice were injected with an hM4D inhibitory DREADD virus to chemogenetically silence VH. Later the mice underwent either no trauma or a foot shock trauma consisting of 10 1mA foot-shocks randomly applied over 60 minutes. They were then tested for aggression and social response using two distinct behavioral assays known as Resident Intruder and 3-Chamber. Half the mice received DCZ, a ligand used to activate DREADDs, while the other half received a control vehicle prior to each behavioral assay. Our findings show that silencing of the VH led to attenuated TIA and TAS when compared to control groups. Next, using retrograde viral tracing, activity-dependent neuronal tagging, and immunohistochemistry, we examined the existence and extent of overlapping neuron populations in the VH. These findings suggest the VH plays an important role in encoding and responding to trauma. They also highlight the importance of continued research into how behavioral changes are manifested in the brain and how these experiences are studied.

Anxiety disorders are increasingly prevalent, and can be exacerbated by drug use, which can contribute to further drug seeking behavior. The underlying neural mechanisms of this relationship are not fully understood, but dopamine transmission is thought to play a key role. The goal of this project is to develop innovative tools to elucidate the role of dopamine and drugs of abuse on anxiety-like behavior and its relation to drug seeking in mice. Specifically, dopamine sensors and 2-photon microscopy via implanted endoscopic lenses, will be used to image dopamine dynamics in the NAcc of behaving mice while they are engaging in a virtual environment (VR) mimicking drug exposure and stress conditions. Using the simulation, mice are exposed to fearful stimuli, which will be related to behavioral responses (movement distance, speed, direction) and extracellular release events. By combining these techniques, we will be able to gain a deeper understanding of how dopamine terminal signaling contributes to drug seeking. This research has the potential to shed new light on the neural relationship between drugs of abuse and anxiety. This could help to inform the development of novel drugs and treatments for this disorder.

Authors: Andrew Call. Mentors: John Chaston. Insitution: Brigham Young University. The main goal for this project is to confirm previous predictions of specific genes that may influence flies’ dietary preference to consume lactic acid bacteria (LAB). The preference of LAB is a normal phenotype that flies have, because the bacteria is essential for their gut microbiota. A previous genome-wide association study (GWAS) by another student in my mentor’s lab predicted genes that lead flies to prefer to consume diets that have live LAB. This genetically determined fly phenotype was measured by calculating the frequency and number of times the flies would choose the LAB inoculated diet over a control diet. My role will be to test if 7 genes have the influence predicted by this previous analysis. The experiment will follow close with the one previously performed by the student who predicted the genes I’m testing. I’ll be using a flyPAD which has a small arena (cage) that will hold one fly. Inside that arena are 2 wells that contain food. These wells have sensors attached to them, so each time the fly takes a sip of food, an electronic signal will be sent to a computer that keeps track of the number of sips from each well, the duration of each sip taken and time in between each sip and graph all the results taken for comparison between a control group and the test groups. I will starve 48 female mutant drosophila melanogaster for 3 hours prior to the experiment and then place them inside the flyPAD where I have previously placed 1 μl of 1:1 yeast-glucose diets in each well, however I will inoculate 0.05 μl of LAB in one of the diets. I will track each sip the flies take from each of the two foods for 1 hour. To measure accurately, there will be 2 controls also being tested. I will use flies that do not contain the genetic mutation and I will also have control arenas where both food wells do not contain LAB.I expect that any mutant that has a reduced preference for LAB-inoculated diet relative to the control diet represents a validated prediction of the previous study. In some cases, there may be no variation in preference for the control or LAB-inoculated diet, indicating a gene that does not contribute to fly preference for LAB in the diet. If none of the mutants tested validate the genome-wide association predictions, I will go back to the gene list and select one additional subset of genes to test if these influence the genetic prediction. We previously focused on genes that had multiple hits in the previous experiment, regardless of how significant the predictions were. In this second round, I will simply select the ten most significant remaining genes. Overall, this project will help confirm the previously selected genes with their association with a diet preference of lactic acid bacteria, improving the gut microbiota of Drosophila melanogaster.

Authors: Danielle Black. Mentors: Chris Anderson. Insitution: Utah Valley University. Attention Deficit Hyperactivity Disorder (ADHD) is a common psychiatric disorder diagnosed in children, characterized by impulsivity, inattention, and hyperactivity. It is frequently co-morbid with eating disorders, primarily bulimia nervosa (BN) and binge-eating disorder (BED). Impulsivity is an important factor in increasing the risk of binge-eating and subsequent feelings of guilt, which may prompt purging behaviors. This often manifests early in childhood as loss of control while eating and can indicate future development of an eating disorder. The current project aimed to assess the link between ADHD symptoms and disordered eating in Utah Valley University alumni. After obtaining IRB approval, 265 alumni responded to an email survey containing nineteen questions regarding ADHD symptoms and three items related to disordered eating. Pearson correlations revealed a significant association between ADHD symptoms and binging (r=.22, p <.01) as well as guilt about eating (r=.17, p <.01). Limitations of the study include the absence of a clinical ADHD diagnoses, relying instead on self-report, and the homogeneous sample, restricting its generalizability. The study was bolstered by its comprehensive coverage of ADHD symptoms and an adequately large sample size to detect statistical significance. This study provides valuable information for those suffering from eating disorders and the clinicians that treat them. Future research could assess the interplay between treating ADHD and reducing the risk of eating disorders. Notably, purging and ADHD symptoms were not significantly correlated, and future research could further explore that relationship. In conclusion, the relationship between binge eating and ADHD symptoms should be acknowledged by clinicians.

High levels of sexual satisfaction have been correlated with higher levels of marriage satisfaction (Litzinger & Gordon, 2005), relationship satisfaction (Santilla et al., 2008), and mental health and general well-being (Brody & Costa, 2009). While we know that sex frequency and frequency of orgasm affect sexual satisfaction (Barrientos & Paez, 2006), we also need to explore nonsexual factors that affect sexual satisfaction. The existing literature of the effects of religiosity on sexual satisfaction is contradictory, and may have mediating factors such as sex guilt or marital status (Hackathorn et al., 2016). The proposed study aims to examine the effects of religious identity and marital status on sexual satisfaction by measuring sexual-spiritual integration. We predict that unmarried individuals will score higher than married individuals, which indicates a lower sexual-spiritual integration. The findings of this study will add clarity to the convoluted findings in the existing literature , and will help identify nonsexual factors that affect sexual satisfaction. The findings of the study will also provide insight that may help healthcare workers, pastoral counselors , and therapists to better service their clients. Results are forthcoming.

Over the past two decades, studies have documented a 20% decline in Quaking Aspen (Populus tremuloides) populations in western North America (Worrall et al., 2015; Stanke et al., 2021). This phenomenon has been fittingly characterized Sudden Aspen Decline (SAD), and is an increasingly pressing issue as the role of aspen as an ecologically irreplaceable keystone species impacts the health of the surrounding forests (Singer et al., 2019). SAD has been attributed to the interplay of climate change-driven drought and other biotic and abiotic factors that are less well characterized (Anderegg et al., 2013a). One potential contributor to SAD is biotic pests and pathogens (Marchetti et al., 2011; Anderegg et al., 2013a; Worrall et al., 2015). My study system includes both natural populations of aspen representing a precipitation gradient and a controlled garden experiment. The field experiments span five distinct sites across Utah & Colorado, selected and montintered by the Anderegg lab of the University of Utah. The experimental garden contains approximately 300 tree saplings subjected to various levels of drought stress, managed by the Anderegg lab on the University of Utah campus. Through the integration of both controlled and natural experiments, my research aims to comprehensively evaluate the impact of drought exposure on pathogen abundance and chemical defenses in aspen trees.Over the past two decades, studies have documented a 20% decline in Quaking Aspen (Populus tremuloides) populations in western North America (Worrall et al., 2015; Stanke et al., 2021). This phenomenon has been fittingly characterized Sudden Aspen Decline (SAD), and is an increasingly pressing issue as the role of aspen as an ecologically irreplaceable keystone species impacts the health of the surrounding forests (Singer et al., 2019). SAD has been attributed to the interplay of climate change-driven drought and other biotic and abiotic factors that are less well characterized (Anderegg et al., 2013a). One potential contributor to SAD is biotic pests and pathogens (Marchetti et al., 2011; Anderegg et al., 2013a; Worrall et al., 2015). Recent investigations have indicated a link between SAD and specific microbial diseases, suggesting that the increasing frequency and severity of droughts due to climate change might make aspen more vulnerable to certain pathogens, even though many of the most common pathogens of aspen in general require more abundant water (Aung et al., 2018). For example, the foliar Melamspora fungal pathogens require abundant water and are not frequently observed in drought stressed trees.On the other hand, Cytospora, which causes a devastating canker disease in aspen trunks, occurs at higher frequency in plots of trees suffering damage from drought (Guyon, 1996). Lin et al. (2023) shows changes to phyllospheric microbiome in aspen during drought, but far less is known about the leaves specifically. Could drought lead to an altered microbiome in aspen leaves? If different or possibly opportunistic pathogens are better able to colonize the leaf tissue under drought stress, this may be the case.It’s known that plants with a reduced diversity of microbiomes are more susceptible to pathogens (Zheng et al., 2020), but the there is little understanding how drought may reduce microbial diversity in aspen. Aspen have two main groups of chemical defenses (SPGs and CTs) that occur in relatively high levels in the leaf (Lindroth et al., 2023). It is well established that these defend against insect herbivores and that they come with a trade-off for plant growth (Marchetti et al, 2011). There is some observational evidence that these secondary compounds have an effect on pathogens (Jacoby et al., 2021), but there are few controlled studies on this idea. Additionally, Metlen et al. 2009 describes how trees in North America produce higher rates of these metabolites under wetter conditions, attributed to possible UV protection. However, the impact of additional environmental changes have of on the abundance of these compounds is understudied. Aspen are an ideal system to study forest disease and drought because the genus’ (Populus) genomes are easily sequenced and relatively tractable, aspen generally exhibit rapid vegetative growth, their defensive chemistry is relatively well known, and most importantly, they grow in cloned groves that reduce the genetic variation in experiments (Lindroth et al., 2023, Luquez et al., 2007).

Heart disease ends the lives of nearly 700,000 people each year and has been the leading cause of death in the United States since 1950. Around this time researchers discovered that some modifications involving our genetic code could be altered to affect gene expression but leaves the DNA intact, which was later termed epigenetics. Today we’ve discovered that these epigenetic modifications, including post translational modifications (PTMS), regulate genes linked to cardiovascular disease. We recently examined the histone lysine methyltransferase SETD7, which is most prominently known for its ability to methylate histone H3K4. SETD7’s expression is upregulated in multiple types of heart disease in both humans and mice and is essential for cardiomyocyte differentiation in embryonic development. In addition to its ability to methylated H3K4, SETD7 has been shown to methylate 8 other histone residues. To further characterize the histone residues methylated by SETD7, we carried out an unbiased analysis of lysine residues methylated by SETD7 using an in vitro methyltransferase assay coupled with tandem mass spectrometry. We hypothesized that SETD7 may modify additional sites than those that have previously been identified. Our analysis determined that SETD7 monomethylates two novel residues on histone H3: lysine 36 (K36) and lysine 122 (K122). These sites of modification were also confirmed by western blotting for site specific antibodies to these methylation marks. Although our understanding of both these residues is limited, we do know that K36 methylation is linked to DNA replication and genomic stability while K122 methylation is downregulated in drug-resistant MCF-7/ADR cancer cells. These two novel methylation sites suggest that this lysine methyltransferase plays a more complex role in regulating epigenetic modifications and gene expression than previously recognized. Although the identification of this new enzymatic activity for SETD7 is important for understanding the dynamic function of methyltransferases, additional studies will be necessary to fully elucidate the role of SETD7 in cardiac physiology and gene regulation.

Authors: America Cox, Kendra Autumn , Bryn Dentinger. Mentors: Bryn Dentinger. Insitution: University of Utah. Neotropical ants of the Attini tribe evolved the innate ability to farm fungi. Agaricomycetidae contains two clades that are cultivated by ants: the lepiotaceous and pterulaceous cultivars. However, there are free-living relatives phylogenetically distributed throughout each cultivar clade. Comparison between the free-living relatives and attine system cultivars may identify the evolutionary differences caused by, or initially enabling, agricultural symbiosis. Our research compares free-living relatives and cultivars through genomic and metabolic analysis. Attines undertake significant cultivar maintenance through the regulation of pathogenic contamination of their fungal “gardens” as well as the provision of specific growth substrates, including insect frass. Noting the apparently specialized substrates cultivars receive from the ants, we conducted a pilot test for a growth media preference between a lepiotaceous cultivar, a pterulaceous cultivar, and a free-living pterulaceous relative. We placed the fungi on regular PDY media and PDY media infused with caterpillar frass, and the cultivars either changed structure or had improved growth on the frass-infused media. Following the pilot test, we will run metabolic assays on the cultivars and free-living relatives on different media types. This may indicate a media preference which gives further insight to the attine-fungal symbiotic relationship opposed to the fungal free-living relatives revealing pieces of the fungi’s evolutionary history. We performed DNA extraction, PCR testing, Sanger sequencing of the ITS region, and then whole genome sequencing on the cultivars and their free-living relatives. Sanger sequencing allowed us to build phylogenetic trees to examine the relationship between the free-living fungi and cultivars. The whole genome sequencing allowed us to use antiSMASH software to generate predicted secondary metabolite clusters in a fungi species that “escaped” cultivation, a cultivar, and a free-living relative. This preliminary data suggests a diversification of fungal secondary metabolites occurs after attine domestication. By looking at fungal metabolic and genomic data, we hope to gain insight into the fungi’s evolutionary history and agricultural symbiosis.

The mushroom body of the Drosophila melanogaster is a structure in the brain that is necessary for learning, but much of how it functions remains unknown. In this model organism, D. melanogaster’s mushroom body neurons, known as Kenyon cells, and input projection neurons have connections that are random and biased—in which some projection neurons connect with Kenyon cells more than others—allowing the fly to potentially prioritize the learning of particular odors. I investigated the functional consequences and characterizations of these biases in order to understand the biological role they play for the fly using a theoretical and experimental approach. With a computational model of the D. melanogaster olfactory system, how biased connectivity to the mushroom body influences its ability to form associations with various odors and distinguish between similar odors was explored. Experimentally, the morphological features of olfactory circuits were characterized by low to high connectivity rates to the mushroom body, allowing us to see the unique features in these circuits that are beyond the different connectivity rates. Through a combination of immunohistochemistry and confocal microscopy, high-quality images were generated of these different neuronal olfactory circuits and their morphological qualities, such as the number and volume of boutons they project to the mushroom body. Altogether, these findings demonstrate how neural connectivities behind learning shape the representation space in D. melanogaster and impact its learning outcomes.

Recent advancements in gene therapy have pushed towards the prevention and treatment of a diverse spectrum of disorders and diseases that are caused by misregulation of gene expression programs and their transcriptional regulators. However, the profoundness of the field means that much of the mechanisms and effects of regulation are unknown and understudied. Here, we explore the limits of flexible exogenous gene expression and its potential use in optimizing efficacy and specificity in gene therapy interventions while minimizing the possible associated risks. This is made possible by exploiting the Tet-On system of inducible transcriptional regulation, which allows the expression of any target gene to be reversibly, specifically, and differentially controlled. In this system, the tetracycline repressor (TetR) binds the tetracycline operator (TetO), impeding transcription of any downstream gene embedded by the researcher; tetracycline dosing causes TetR to adopt a new conformation that removes it from TetO, inducing gene expression on command (Das et al., 2016). Because of the diverse utility of this system, we are in pursuit of developing novel TetR-TetO orthologous pairs that do not interfere with this wild-type circuit and can be used to regulate gene expression in parallel. As a first step to generating TetR-TetO orthologs, we mapped the usage of TetO by TetR in a massively parallel reporter assay (MPRA) by engineering an extensive library of mutant TetOs and quantified the resulting range of TetR regulation through reporter gene expression. From this screen, we identified candidate TetO mutants to direct the evolution of the wild-type TetR towards complementary states to those TetO mutant sequences. Our preliminary findings indicate that the engineering of distinct synthetic expression cassettes based on the TetR-TetO operon is feasible. These novel tools may ultimately allow us to build a synthetic genetic circuit to model regulatory feedback loops that can help discover malfunctions in cell growth, reproduction, and cycling that can arise from genetic disorders and can lead to disease.1.

Conversations about conspiracy theories have become prevalent in contemporary Western society, reaching through all levels of private, academic, and governmental discourse. Part of this discourse revolves around the question of what exactly conspiracy theories are and how they occur within a population; much of the recent academic treatment of conspiracy theories identifies them as a kind of propaganda whose purpose is to promote particular political agendas, especially those with apocalyptic concerns (Cassam 2019). While conspiracy theories certainly have been and continue to be used to further certain political aims, this understanding of them as totally propaganda provides only a narrow insight that fails to capture the scope of how conspiracy theories occur in the real world and how they are experienced by the people who believe in them. Philosophy and political theory can only be so informative, and they lack an ethnographic perspective to instruct on the lived reality of conspiracy theories (Hickman & Webster 2018). During my fieldwork in Belfast, Northern Ireland, I conducted ethnographic research with a group of people who could easily and accurately be labeled conspiracy theorists; my experiences with them provide insight into how conspiracy theories actually operate in the lives of living people. Contrary to popular claims, conspiracy theories—especially those that deal with the end of the world as we know it—are not experienced as primarily political phenomena. Instead, they are experienced as religious truths, and the millenarian activism that often surrounds them is enacted because of a conviction of personal obligation to the truth. Framing conspiracy theories as mere propaganda or dismissing them as the effects of cognitive dissonance incorrectly discounts the empirical reality of these beliefs for the people who have them.

Background music refers to music that is played while the listener’s attention is focused on another task (Radocy & Boyle, 1988). Research suggests that the effect of background music on performance during a cognitive task showed improvements in episodic memory. Music activates the limbic system which is involved in controlling memory(e.g., Blood et al., 1999). The purpose of this study is to predict the relationship between music and performance on a cognitive task. It is hypothesized that students who listen to white noise while studying a text will recall more information, than those listening to classical music or pop music. In particular, the lyrics in pop music will be especially distracting(Cheah, 2022). Studying the relationship between music and performance on a cognitive task has implications for understanding memory. Results are forth coming

According to the Center for Immigration Studies, “the total foreign-born or immigrant population in the U.S. hit 47.9 million in September 2022- a record high in American history. When non-English immigrant families arrive in the United States they face the challenges of new customs, rights, and practices in their new home. In the United States various NGOs, government aids, and non-profit organizations are available to immigrants to help them navigate these challenges. Evaluations about the efficacy of these resources should be considered with the increasing number of immigrants in the United States. In this research, we focus on one of these resources, a mental well-being support group geared to immigrants but attended mostly by Latina women. The support group is currently held at a non-profit community center the South Franklin Community Center (SFCC) in Provo, UT, and sponsored by the organization Inciativa Latina para el Bienestar Emocional [Latino Initiative for Emotional Well-being]. To consider the efficacy of this support group in this research we explore the following questions 1) How does support get produced in the context of this support group at the SFCC? 2) Does (and if so, how does) participating in these support groups expand the agency of participants? (By agency, I refer to the capacity or condition of someone to have control or power to act).

Feasibility Analysis of Mixed Solvent Waste Recycling: A Green Chemistry ProjectUndergraduate Research Session, Green Chemistry submission Amanda Pay, Jai Mai Chong ACS Student Affiliate Advisors; Mary Alvarez, Ron V Valcarce, Wesley Sanders, Peter J Iles, John Flood This research project explores the first of the 12 principals of green chemistry, waste reduction through solvent recycling. Solvents are widely recognized to be a considerable environmental concern. Many industrial chemical processes generate significant amounts of hazardous and toxic chemical waste due to solvents used to facilitate chemical reactions. The reduction of their use is one of the most important aims of green chemistry. In response to this, solvent recyclers have been created which attempt to clean and purify solvents for re-use, thus reducing the amount of solvent waste a chemical company generates. In this project we analyzed before and after samples of mixed solvent containing hexanes, ethyl acetate, and other solvents processed with a CBG biotech solvent recycler. The results were used to improve recycler settings for solvent resolution and assess the effectiveness of waste reduction using such methods.
