The Family Baetidae, is in the order Ephemeroptera, also commonly known as Mayflies. The first baetids were described around 1815 by Leach, and since there are more than 900 species have been described. The family Baetidae is an important group of mayflies because of their position on the mayfly tree of life in that they are a key to understanding evolutionary trends, such as the origin of wings and flight. Taxon sampling for this study consisted of over 100 taxa, representing ??? genera, from lineages distributed geographically worldwide, except Antarctica. Two main datasets were constructed. The genes 12s, 16s, H3, 18s, 28s and CO1 were used as part of a traditional dataset. Targeted capture sequencing was used to generate a phylogenomic dataset, consisting of over 400 loci. Trees were reconstructed from the aligned datasets, and the results were compared. The phylogenomic data resulted in a much more resolved topology.

determine bacteria is growing the bacteria on agar and then identify the bacteria via the API system (analytical profile index). In some medical cases, 24 hours is too long to wait, especially if a patient needs antibiotics. Raman spectroscopy uses laser light to excite a spectrum specific to each molecule. This molecular specificity enables Raman spectroscopy to identify the species of bacteria without a lengthy growth period. Raman spectroscopy is non invasive and only needs one bacterium for detection. It is therefore faster than growing bacteria and identifying via the API system.

From other research groups we know that Raman spectroscopy is able to classify bacteria, albeit with limited breadth of bacterial types. The next step is to implement imaging techniques to make the identification even faster, so that those techniques can be used in hospitals to determine pathological bacteria, so that the treatment can be given faster. Furthermore, when a hospital is unsure whether the patient has a disease caused by bacteria usually they start treating the patient with antibiotics in case they are infected. If identification only take a few hours instead of two to three days, doctors would only prescribe antibiotics when necessary, thus decrease the risk of multiresistant bacteria.

Kidney cancer in both men and women is among the top ten most common cancers, where the risk in men is estimated at 1:48, and women at 1:83. The issue with kidney disease is that it is difficult to accurately diagnose early-on. Methods of diagnosis that are currently established are expensive and highly invasive if at all accurate. Our research is focused on developing a fast, reliable and cost-effective method of diagnosing kidney disease by the use of fluorescent quantum dots (QDs). When mixed in a solution that contains protein biomarkers, QDs can act as biosensors because the protein alters their fluorescent properties. With QD biosensing, optimal conditions were discovered for the size of QDs and buffers used for detecting different protein biomarkers. The study provides empirical evidence that the alteration is distinguishable between healthy and cancerous levels of protein.

Carbon Monoxide (CO) has been found to have a wide range of potential therapeutic effects. For example, low concentrations of CO have been shown to produce anti-inflammatory, anti-hypoxia, anti-proliferative, and anti-apoptotic effects, as well as vasodilation. CO-releasing molecules (CORMs), particularly those which release CO upon triggering with light in the visible range (photoCORMs), are of significant current interest for targeted CO delivery. Our laboratory is developing extended flavonols as highly tunable tunable photoCORMs. In this presentation, the synthesis, characterization, and CO release reactivity studies exploring the use of flavonol esters as CO delivery molecules will be presented.

The Sundance Sea covered much of western North America during the Middle to Late Jurassic Period. Deposits from this vast epeiric sea are now widely exposed across the region, including the Stump Formation in northeastern Utah, which consists of sandstones and shales reflecting shallow marine deposition. Well-preserved belemnites (Pachyteuthis densus, Oxfordian Stage, ~156 Ma) collected from this unit preserve stable isotope data (_18O and _13C ) that can be used to better understand the paleoceanography and paleoclimatology of the area, as well as possibly some paleobiologic characteristics such as migration patterns through the life cycle and age at sexual maturity and death. Incremental growth of belemnites created growth bands that record isotopic values through various life stages, thus potentially providing information about the life history traits of these organisms, in addition to seasonal temperature variations. Preliminary results suggest our material is consistent with previous reports from other locations in the region, with paleotemperatures in the 17 to 20° C range. In addition, there is some indication of seasonal variations. However, analyses of more samples and further evaluation of potential diagenetic alteration is necessary before more robust conclusions can be drawn.

Surface Brightness Fluctuation Distances to Galaxies Using Elliptical and Circular Masks

We have measured the Surface Brightness Fluctuation (SBF) distances to 12 galaxies. SBF is usually used to measure distances to giant elliptical galaxies that have uniform ages and composition. On the other hand, galaxies that are more disk-shaped potentially have a range of ages, they may have an SBF and color gradient. Elliptical masks that match the shapes of disk galaxies can give a more accurate SBF and color gradient than circular masks. The purpose of this study is to measure the discrepancies between the SBF distances using the two types of masks. For giant elliptical galaxies, the two methods give similar results ($\leq$ 2\%). For disk galaxies, the discrepancies are bigger (up to 6\% difference).
