Lee, Charles Chang Suk | A demonstration apparatus for optical pumping of rubidium | Optical pumping refers to the use of light in order to elevate ("pump") the spin (intrinsic angular momentum) of an atom or molecule. This process is of interest from a pedagogical and experimental perspective because it encapsulates fundamental properties of atomic physics and quantum mechanics.

Allam, Jeremy | Low-energy satellite transfer from Earth to Mars | A new type of satellite transfer that uses half the amount of fuel as conventional transfers has been discovered. This transfer, called a low-energy transfer, proved to work in 1991 when a Japanese satellite successfully went in orbit around the moon using this technique. Since then, more research h... | Space vehicles -- Dynamics -- Mathematics Space flight to Mars -- Mathematics | 2015-04 |

Ellingson, Drew | Bitangent lines to planar quartic curves in algebraic and tropical geometry | Bitangents are lines which are tangent to a curve at two points. The bitangents of a classical quartic are well understood, and a result originally due to Cayley tells us that there are always precisely 28 bitangents to a generic quartic plane curve. When looking at Tropical Geometry, the situation ... | Tropical geometry; Curves, Quartic; Curves, Algebraic; Bitangents | 2015-04 |

Estrada, Johanna | BCR-ABL1 compound mutations combining key kinase domain positions confer clinical resistance to ponatinib in Philadelphia cromosome-positive leukemia | CML 1s caused by a random reciprocal translocation that joins the ABL1 gene on chromosome 9, with the BCR gene on chromosome 22. The result is the formation of the oncogenic BCR-ABL1 gene. This derivative chromosome is widely known as the Philadelphia Chromosome (Ph+), and it encodes a deregulated, ... | Leukemia -- Genetic aspects -- Research Leukemia -- Treatment -- Research | 2014-04 |

Evans, Kathryn S. | Defining the interaction between ETV4 and mediator subunit MED25 | Chromosomal rearrangements resulting in an overexpression of a subset of ETS transcription factors (ETV1, ETV4, ETV5, and ERG) are found in over 50% of prostate cancers (Tomlins et al., 2005). ERG and ETV1 have both shared and distinct gene targets, yet overexpression of ETV1 is often found to be as... | Transcription factors; Prostate -- Cancer -- Genetic aspects; ETV4 | 2015-05 |

Fernandez, Florence | Evaluation of environmental education in high school science courses across Salt Lake City, Utah | While the effects of pollution become Incredibly more evident in the air of the Salt Lake Valley, many Utah high school students still lack the knowledge and information necessary to take preventative and immediate actions to protect their health and their environment. In this study, the reasons for... | Environmental education -- Utah -- Salt Lake City; Science -- Study and teaching -- Utah -- Salt Lake City; Air -- Pollution -- Utah -- Salt Lake City | 2015-05 |

Black, Alyssa | Identifying hybrid male sterility genes in Drosophila Pseudoobscura | Speciation, the process of one species splitting into two separate species, often involves the evolution of hybrid sterility or hybrid inviability. These reproductive isolating barriers are caused by negative interactions between genes called hybrid incompatibilities. Identifying hybrid incompatibil... | Infertility, Male -- Genetic aspects Drosophila pseudoobscura -- Genetics Male sterility genes | 2015-05 |

Beams, Alexander | Implications of antibiotic use for co-infections when a fitness trade-off for resistance is present | How much does indiscriminate antibiotic use promote the spread of antibiotic-resistant infections in a population? Assuming a fitness trade-off for resistance exists, it is possible for an antibiotic-vulnerable strain to outlast a resistant type within an untreated host carrying both. That means pru... | Drug resistance in microorganisms -- Mathematical models Co-infections | 2015 |

Wang, Wenyi | Imaging in a homogeneous aluminum plate by using ultrasonic waves | This project is about detecting and imaging damage (such as cracks) in a plate by using ultrasonic waves. The waves are generated by a source (an ultrasonic transducer) that is part of a robot that can move on the plate. The waves traveling in the plate are recorded at a receiver (another ultrasonic... | Ultrasonic transducer - Mathematics; Kirchoff migration - Research | 2014-12 |

Neville, Roselyn | Constitutively activated AKT is not sufficient to keep cells alive following epithelial cell extrusion | The PI3 kinase (PI3K)/AKT signaling pathway regulates many fundamental behaviors of the cell. If any of the key members of this pathway are deregulated, it can lead to malignant changes in the cell. AKT enhances the survival of cells by inhibiting pro-apoptotic processes, and promoting pathways for ... | PI3K/AKT - Chemistry; Cancer metastasis | 2014-05 |

Bell, Anthony W. | The expansion of pinyon-juniper woodland and the appearance of peromyscus truel in the Toiyabe range of central Nevada | In the early twentieth century field biologists from the University of California Museum of Vertebrate Zoology conducted vertebrate faunal surveys throughout the Great Basin region. Over the past several years we have been conducting resurveys of many of the localities visited by MVZ scientists.
