101 Yamada, KayleneComparing Tollerance of Neotoma Lepida on Native Versus Novel Toxic DietsHerbivorous animals often ingest plants that protect themselves with chemicals, and these toxins typically differ in composition from plant to plant. For instance, juniper (Juniperus osteosperma) is dominated by terpenes, such as α-pinene, whereas creosote bush (Larrea tridentata) contains a cockta...2017
102 Zheng, KennethDyck Paths and Random TreesWe give an expository survey of random trees, focusing on the interplay between plane trees and Dyck paths. The material explained here summarizes what can be found in Aldous [1], Le Gall [10], and Drmota [6]. The bijection between plane trees and Dyck paths serves as motivation for the connection b...2017
103 Gardner, JennaThe Disparity Between Student Science Writing and Professional Sciencetific WritingThere exists a disparity between student scientific writing and professional scientific writing. The audience, format, and intention of student papers as presented in the science classroom is different from those in the scientific field where the goal is to fully convince an unfamiliar audience and ...2017
104 Khuu, ScottIdentifying Retinoic Acid Dependent Mechanisms of Neural Crest Epithelial-Mesenchymal TransitionCancer metastasis is one of the distinguishing traits that make the disease difficult to treat. The steps of tumor invasion are similar to a process called epithelial to mesenchymal transition (EMT). Retinoic acid (RA) is shown to inhibit EMT and may cause an increased transcription of the gene, ski...2017
105 Wilson, AlexisWest Antarctica as a Natural Laboratory for Cloud MicrophysicsClouds contribute to energy regulation in the global climate system. Remote and unaffected by local pollution sources, Antarctica offers a unique laboratory to study clouds and their influence on the surface energy budget. The study of these clouds is particularly interesting as global temperatures ...2017
106 Kim, Alexander H.DPP Signal Regulation Through O-Linked GlycosylationDorsal closure in Drosophila is an embryogenic event that involves coordinated cellular shape changes. A series of interconnected signaling cascades are utilized to accomplish this task, one of which is the Decapentaplegic (Dpp) pathway. Dpp is a member of the TFG-β family of secreted cytokines, wh...2017
107 Woodruff, DerekUncovering Synaptic Defects resulting from loss of the intellectual disability and autism-associated gene Kirrel3Neurodevelopmental disorders severely impact an individual's life. Surprisingly, the genetic and cellular cause of over half of intellectual disability cases and more than 80% of autism spectrum disorders remain undiscovered1,2. It is likely that mutations in molecules regulating synapse development...2017
108 Cocke, Rebecca C.Evaluating the Catalytic Activity of Iron and Nickel Impurities in Bare High-Pressure High-Temperature NanodiamondMany metal nanoparticles are used as catalysts for various reactions and are held on supports. High-Pressure High-Temperature nanodiamonds (HPHT ND) are able to support metal nanoparticles even under strenuous chemical environments due to their robust nature. The production of HPHT ND includes the u...2018
109 Roestenburg, JessicaTesting the Perceptual Salience of Spectral Content in Zebra Finch SongBirds actively adjust the resonance properties of the upper vocal tract during singing, which results in specific harmonic structures of song elements. To what degree upper vocal tract filtering is relevant for the perceptual salience of song is poorly understood. This research utilizes (1) a biolog...2018
110 Pearson, CassidyMajor Urinary Protiens as a signal of genetic Quality and Infection statusThe Hamilton-Zuk hypothesis suggests that susceptibility to infectious disease is so important that many physical traits, particularly secondary sexual characters, will evolve to signal genetic quality for resistance to prospective mates. We expanded upon this theory using the house mouse (Mus muscu...2018
111 Ellis, James H.Refractory status epilepticus and chronic kidney disease in a large pedigree due to a variant in the mitochondrial encoded trna phenylalanine (MT-TF) geneMitochondrial disorders present with a wide spectrum of neurological manifestations. Clinical syndromes are described largely by phenotypic indicators. Epilepsy is a common but not universal feature. Myoclonus epilepsy with ragged red fibers (MERRF) is a common clinical syndrome that presents with e...2018
112 Beseris, EthanBiological impact protection in human facial hairOur study investigated selective mechanisms that influenced the evolution of facial hair in human males (Homo sapiens). Beards are often perceived as an indicator of masculinity and social dominance in men, suggesting that they may play a role in male contest competition. Some authors propose that t...2018
113 Mercer, MarianneEstablishing a System for Structure-Function analysis of the Novel Role that NUP153 Plays in Nuclear AssemblyIn mitosis, equal partitioning of DNA between daughter cells requires an integrated series of events. At the start of anaphase the chromatin separates and forms two chromatin discs. This chromatin is then targeted by nuclear membrane proteins and membrane to form the nuclear envelope. These membrane...2018
114 Fackler, Anderson N.Identification of Kin-20 and UNC-119 Knockout suppressors associated with neuronal development and maintenance in C. elegansNeurons comprise the nervous system-the essential signaling and communication system for nearly all multicellular organisms. To coordinate cells across an entire organism, they must grow to be relatively long. Therefore, neurons extend axons from the cell body. Immature neurons extend growth cones a...2018
115 Ong, ElaineIdentifying Natural Genetic Modifiers of Apoptosis and Retinal DegenerationApoptosis, or cell death, is an integral part of many diseases such as neurodegeneration, retinal degeneration, and cancer, yet it is unclear how apoptosis varies among individuals in a population. Retinitis pigmentosa (RP) is a retinal degeneration disease characterized by phenotypic heterogeneity ...2018
116 Smith, SarahEffects of Mitochondrial Mobility on Astrocyte FunctionWithin the brain, astrocytes provide support and influence the excitability of neurons by regulating the extracellular levels of potassium (K+) and glutamate. These glial cells play a vital role in neural homeostasis by regulating the concentration of neurotransmitters at the synapse, therefore modu...2018
117 Bell, MarisaCharacterization of Polyphenols in I. UmbelliferaSecondary metabolites in plants, including polyphenolics, may be responsible, in part, for diversity in the tropics. Variation in chemical defense among species of trees encourages specificity in herbivorous insects. Due to the short lifespan of insects compared to trees, diversity in chemical defen...2018
118 Davis, Kacey A.Expression and Purification of Augertoxins: Searching for Novel Protein Folds in Venomous Marine SnailsThis study describes a method for bacterial expression and purification of previously uncharacterized proteins. The proteins chosen for this study come from auger snail toxins, which have evolved to help the snail hunt and kill their prey. Evolutionary pressure between predator and prey selects for ...2018
119 Blanton, Joseph P.AC Magnetic Susceptibility of Sub-Millimeter Superconductor Samples at Extreme ConditionsSuperconductivity is a unique state of matter observed at cryogenic temperatures in many materials. Superconductors are defined as materials that have zero DC electrical resistance and perfect diamagnetism below a critical transition temperature, Tc. These properties are very useful for many applica...2018
