Taylor Maxwell and Dr. Duke Rogers, Zoology Mexico is classified as a “megadiversity” country, which means that it has more species of plants and animals than the vast majority of other countries in the world. For example, there are ca. 4,750 species of mammals known to science, and more than one of every seven can […]

Predicting Gas-phase Reaction Rates For Elementary Diatomic Substitutions Using Molecular Dynamics Simulations
Karl Fails and Dr. Richard Rowley, Chemical Engineering The purpose of this study was to examine a new method for predicting elementary gas-phase reaction rates using molecular dynamics simulations. The diatomic substitution reaction: was to be used as a test model for its simplicity. Molecular dynamics simulations were to be used to calculate the motion […]
Phylogeny of the Order Siphonaptera Based on Molecular Data
Alison Swindle and Dr. Michael F. Whiting, Zoology Background The insect order Siphonaptera (fleas) has been historically significant for thousands of years. Beginning as early as 430 B.C. outbreaks of the bubonic plague have swept across continents and killed millions of people. Before fleas were linked with the plague, they were a little known order. […]
PROVIDING A SECOND SOURCE OF NEGATIVE CHARGE ON A “MOLECULAR LEASH”
Eric Nelson, Chemistry and Biochemistry I was awarded the Research and Creative Work Scholarship for the winter semester of 1994 based on my proposal to synthesize a novel organic compound for testing and publication in conjunction with the research group of Dr. Jerald Bradshaw in the Chemistry Department. The Compound as described in my proposal […]
Use of an Intermolecular Tether in [2+2] Photochemical Cycloadditions
Brent Siemssen and Dr. Steve Fleming, Chemistry and Biochemistry Oxetanocin is a nucleoside that occurs naturally in the bacteria Bacillus megaterium (see figure 1a).1 Oxetanocin and its analogues show antiviral activity but have not yet been introduced in any successful drug treatment. Even so, oxetanocin continues to be a model studied to help understand the […]
Molecular Machine Components Observed in the Gas Phase: Self- Assembling Pseudorotaxanes of Cucurbit[n]urils (n=6, 7, and 8) and Doubly-Protonated 1,4-Diaminobutane
Kevin Alan Walker and Dr. David Dearden, Chemistry and Biochemistry Nanotechnology offers the potential of creating machines the size of molecules. Such machines have limitless possibilities in numerous fields: chemistry, computer science, technology, and medicine, to name a few. Molecular machines could be instrumental in creating computers millions of times faster than our present computers. […]
A Molecular Approach to Answering an Anthropological Question Concerning Burial Customs in an Ancient Egypt Population
Jamey Tolman and Dr. Scott Woodward, Microbiology Recent advances in DNA sequencing technology have allowed us to gain knowledge about the ancient populations of the world. A team of BYU students and faculty has excavated a group of bodies, dating from 200 B.C. to 400 A.D., found in the Fag El Gamous cemetery in Egypt. […]
Preliminary Phylogeneic Analyses of the Erotylidae (Coleoptera: Cucujoidea: Erotylidae) based on Molecular Data
James A. Robertson and Dr. Michael F. Whiting, Zoology The Cucujoidea, a very diverse beetle superfamily, includes mycophagous and wood consuming beetles. Within the Cucujoidea is the family Erotylidae (pleasing fungus beetles). The Erotylidae includes 125 genera and approximately 2,500 species, and has a worldwide distribution. Erotylids are known for their striking coloration, including black […]
Molecular Mechanism of Neuronal Communication
Blake Simmons and Dr. Dixon Woodbury, Physiology and Developmental Biology Nerve Cells communicate with each other by synaptic transmission. Synaptic transmission is the release by one nerve cell of neurotransmitters packaged in synaptic vesicles. Proteins known as SNAREs, (e.g., synaptobrevin and syntaxin) are believed to drive neurotransmitter release by inducing fusion (exocytosis) within a presynaptic […]
Molecular Collisional Energy Transfer Efficiency
Jeffery K. Thomson and Dr. Eric T. Sevy, Chemistry and Biochemistry The kinetics of unimolecular reactions are especially interesting in the manner in which they absorb or transfer energy. For a unimolecular reaction to proceed, an activation energy barrier must be overcome. This barrier can be overcome through collisions with other molecules or atoms with […]
