Lead Institution: Oregon Health & Science University
Principal Investigator: Eric Gouaux
Ionotropic glutamate-receptor ion channels (iGluRs) are the major mediators of excitatory synaptic transmission that couple glutamate release to depolarization of postsynaptic neurons in the central nervous system. Among the cation permeable iGluRs...
Lead Institution: Reed College
Principal Investigator: Shivani Ahuja
The manganese transport regulator (MntR) of Bacillus subtilis has long been known to repress uptake of manganese by binding to its operator site and blocking access of RNA polymerase to the promoters controlling expression of manganese uptake...
Lead Institution: La Jolla Institute for Immunology
Principal Investigator: Erica Saphire
Lassa virus (LASV), the causative agent of Lassa hemorrhagic fever, is endemic in Western Africa, infecting over 100,000 people every year, resulting in roughly 5,000 deaths—yet no vaccines are currently available. Six genetic lineages of LASV...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Elizabeth Kautz
Uranium alloyed with 10 wt% molybdenum (U-10Mo) has been selected to replace highly enriched uranium oxide dispersion fuels for use in high performance research and test reactors. Manufacturing U-10Mo alloy fuel involves several complex...
Lead Institution: Clemson University
Principal Investigator: Brian Powell
The objective of this limited scope proposal is to complete a set of micromodel experiments performed during a previous EMSL User Proposal that explored the citrate-promoted dissolution of uranyl-phosphate. Before this study can be published, one of...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Dallas Reilly
In applications of uranium - 6 wt% niobium (U-6Nb) important to NNSA, its mechanical properties are exploited by engineers to achieve desirable mechanical response. When U-6Nb is heated for short times (<2 hours) at low temperatures (200 ?C), it...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Elizabeth Kautz
The accurate quantification and mapping of light element isotopes, such as hydrogen (H) isotopes and lithium (Li) isotopes, is critical to building reliable, accurate mechanistic models during physical changes or phase transformation. In the case of...
Lead Institution: University of California, Los Angeles
Principal Investigator: Tina Treude
Methylotrophic methanogenesis has recently been shown to fuel anaerobic oxidation of methane (AOM) within the sulfate-reducing zone of marine sediments, coining the term "cryptic methane cycle". This fast cycling of methane is likely...
Lead Institution: Michigan State University
Principal Investigator: Alexandra Kravchenko
This proposal requests analysis of a set of samples from a 13C and switchgrass (Panicum virgatum L.) labeling experiment. The goal of the experiment is to assess the fate of the C assimilated by the plants from CO2 during subsequent decomposition of...
Lead Institution: Michigan State University
Principal Investigator: Berkley Walker
The majority of terrestrial plants form root symbiosis with arbuscular mycorrhizal fungi (AMF) which are well studied for their benefits to host plants under drought conditions. These benefits range from improved plant nutrition to enhanced plant...
