Devin Bradshaw and Scott Steffensen, Psychology Introduction Methamphetamine is a highly addictive substance with many negative effects on the user. These effects include detriments to physical health such as “…extreme weight loss, severe dental problems (“meth mouth”), and skin sores caused by scratching. Methamphetamine use also raises the risk of contracting infectious diseases like HIV […]

The Effect of Promoter Region Indels on Expression Bias in Polyploid Cotton Species
Zachary Liechty and Joshua Udall, Plant and Wildlife Sciences Many plants undergo polyploidization events throughout their history, meaning their genome doubles1; the goal of this project was to identify how these polyploidization events lead to changes in gene expression on a nucleotide level. Polyploidization events provide raw material to be acted upon by natural selection, […]
Role of Reactive Oxygen Species in Methamphetamine Modulation of Dopamine Release in the Nucleus Accumbens
Tyler Ekins and Scott Steffensen, Psychology Introduction Methamphetamine (METH) abuse is a problem that continues to cause much harm across the United States. The cost of METH use in 2005 alone was estimated to be 23.4 billion dollars (Nicosia et al., 2009). Other societal costs of METH abuse include suicide attempts, premature death, increased health […]
Dual Species Calcium and Ytterbium Magneto Optical Trap
Alexander Erickson and Faculty Mentor: Scott Bergeson, Physics Department Introduction One area of particular interest in modern physics research is creating a viable fusion system for sustainable energy. Fusion occurs when a high energy plasma is manipulated in such a way that small atoms collide together, combining to create larger atoms and releasing tremendous amounts […]
Developing Utah Juniper into a Useful Species for Dendrochronology
Calli Nielsen and Dr. Matthew F. Bekker, Geography Utah juniper is rarely used by dendrochronologists in tree-ring applications. In the global species database, Utah juniper has a score of 1, which means that it typically only crossdates within its own site, and is therefore not useful in tree-ring research. This mentored research project was conducted […]
Role of ROS (reactive oxygen species) on cocaine-induced DA release in the NAc
Jacqueline Solomon and Dr. Scott Steffensen, College of Family, Home, and Social Science Introduction: Cocaine as a stimulant drug causes Dopamine (DA), a neurotransmitter, to be released in the Accumbens Nucleus (NAc). It accomplishes this by its well-known actions on the DA transporter (DAT). When the DAT is blocked, more DA stays in the synaptic […]
Encroachment of Bwindi National Park, in Relation to Richness and Diversity of Tree Species
Catherine Johns and Dr. Brigham Daniels, College of Law This project originally aimed to research tree richness and diversity using the Point Quarter method in Bwindi Impenetrable National Park but after the first day attempting to work, I learned how impossible the forest actually is. Having never experienced such a dense mountainous forest, not even […]
Do Differently Managed Dairy Cows with Production-related Metabolic Diseases have Similar Protein and Fat Species in Colostrum and Milk?
Holly Martin and Dr. Beverly Roeder, Biology Introduction Production-related metabolic diseases (PRMDs) in dairy cows threaten the livelihood of the animals as well as the productivity and success of the dairy industry. Because dairy cows supply an important food source for humans, understanding, managing, and preventing these diseases protects this source. Management and prevention of […]
Diverging predation environment between two sister species of live bearing fish: boldness, activity, and exploration.
David Money and Jerald B. Johnson, Department of Biology Our study takes advantage of a unique species pair within Brachyrhaphis, Brachyrhaphis roseni and B. terrabensis,, which provides insight into how divergence proceeds once speciation is complete. Brachyrhaphis roseni and B. terrabensis are sister species that occur in the same river drainages throughout northwestern Panama. A […]
Dual Species Magneto-Optical Trap
Daniel Woodbury and Scott Bergeson, Physics Introduction In the last several decades, laser cooling has become the primary tool for atomic research and, in our lab, has facilitated the study of ultracold plasma. Using a novel laser cooling setup, we created a vacuum chamber and related hardware for a dual species magneto-optical trap (MOT). The […]
