The northwestern corner of the Basin and Range Province (NWBR) lies in southeast Oregon where extensive Late Miocene, mafic to bimodal basalt-rhyolite volcanism and extensional faults dominate a stark and arid landscape. Near Lake Abert, the Late Miocene volcanic section abuts Early Miocene, dominantly intermediate composition volcanoes at the Coleman...
A synthesis of over 2000 paleoclimate proxy records is performed via a data assimilation framework that expands upon previous efforts by implementing a suite of physically-based proxy system models, and which provides the first example of an observationally independent, multi-seasonal (DJFM, JJAS) paleoclimate reanalysis. This methodology is contrasted against previous...
Novel mucosal vaccines (LL-M2e, LL-HAe, SG-HAe) were constructed from live, non-pathogenic Lactococcus lactis or Streptococcus gordonii that express conserved regions of HA or M2 antigens from avian influenza virus (AIV) A. All three vaccines evoked antigen-specific serum immunoglobulin G (IgG) responses in vaccinated chickens. The addition of the adjuvant cholera...
This report details ocean water salinity and stable isotope measurements (deuterium (D) and 18O) in water collected from April 17 2018 to April 21 2018 in the coastal waters of Oregon, USA. Measurements were made from surface, ship flow-through, and CTD rosette bottle samples collected as part of a student-led...
The Ratio Mountain Quadrangle is located in Southwest Montana, East of the city of
Butte. This quadrangle features two major geologic units; the Elkhorn Mountain
Volcanics, a series of several ignimbrites of varying composition, and the Boulder
Batholith, a large granite pluton that rose through the EMV. Previous studies in...
Peptide phosphorodiamidate morpholino oligomers (PPMO) are synthetic DNA mimics that bind complementary RNA and inhibit bacterial gene expression. (RFF)₃RXB- AcpP PPMO (R, arginine; F, phenylalanine; X, 6-aminohexanoic acid; B, β-alanine) is complementary to 11 bases of the essential gene acpP (encodes acyl carrier protein). The MIC of (RFF)₃RXB-AcpP was 2.5...
The Boulder Batholith and Elkhorn Mountains Volcanics (EMV) formed concurrently during shortening between ~85-76 Ma near the end of Mesozoic Cordillera arc magmatism. Together they represent an exceptionally well-preserved and voluminous record of continental arc magmatism. We report field and analytical results from studies of the EMV and Boulder Batholith...

There are few modern isotopic ages of igneous rocks and polymetallic (Pb-Zn-Ag-Cu-Au) hydrothermal mineral veins of the Mt. Thompson quadrangle in southwestern Montana. Lithology ages of this region vary from approximately 85-80 Ma Butte granite(Kbg) (Lund et al. 2002) to 48.6 Ma of Lowland Creek Volcanic Field (LCVF) (Dudas et...
The rhenium-osmium isotopic system has the potential to track the maturation of arc crust at lower crustal levels because the ¹⁸⁷Os/¹⁸⁸Os in magmas is sensitive to the age and composition of crust with which they interact. We here present Re and Os isotopic data for a suite of samples from...
