This is a $565,402.98 federal grant award to the California Institute of Technology (Caltech) from the National Aeronautics and Space Administration (NASA) for a research project titled "Towards a New Interpretation of Sedimentary Hopanes Using Bradyrhizobium diazoefficiens as Model System". The project aims to investigate the functions of hopanoids, molecular fossils of bacterial lipids, and understand their role in conferring stress resistance to bacteria, which could help...
This is a federal grant awarded by NASA to the SETI Institute, a non-profit scientific organization, to understand the preservation potential of molecular biosignatures in lacustrine sediments on early Mars. The goal is to determine the rates of degradation for molecular biosignatures in cold, dry environments using sediment samples from Lake Untersee, an Antarctic lake, and an adjacent paleo-lake basin. This research addresses key NASA Exobiology and Astrobiology themes related to the early...
This is a $349,614 grant award from the National Aeronautics and Space Administration (NASA) to the SETI Institute, a non-profit research organization in Mountain View, California. The award supports a focused, pilot program to expand the exploration of chiral signatures in the ultraviolet spectrum for photosynthetic organisms, building on the Institute's prior work in the visible spectrum. The SETI Institute has a history of federal contract and grant awards, primarily from NASA and the...
The National Aeronautics and Space Administration (NASA) awarded a $351,186.25 grant to New Mexico State University (NMSU) for a research project related to the evolutionary ecology of symbiosis between multicellular organisms and bacteria. The objectives are to examine how bacteria evolved under different environmental conditions affect their ability to infect native hosts, measure host immune response to native and non-native bacteria, and determine how abiotic factors impact the fitness of...
This $232,433.44 grant was awarded by the National Aeronautics and Space Administration (NASA) to the California Institute of Technology (Caltech) to conduct research on the early evolution of oxygenic photosynthesis in cyanobacteria. The goal is to gain insights into the pre-phototrophic progenitors of modern cyanobacteria by studying dark cyanobacterial lineages found in termite hindgut microbial communities. The research will involve comparative metagenomics, transcriptomics, and...
This is a $100,158 grant awarded by the National Aeronautics and Space Administration (NASA) to Montana State University (MSU) under the Exobiology program. The grant is to support the research of an MSU assistant professor on developing novel bioorthogonal labeling tools to study extremophilic microbes in geothermal hot springs. The research aims to provide a better understanding of the biotic and geochemical factors that drive microbial activity, which is relevant to NASA's Exobiology...
This federal contract award to Northwestern University, a private research institution, is for a grant to investigate lipid biomarkers from the deep continental subsurface biosphere. The $394,952.99 grant, funded by the National Aeronautics and Space Administration (NASA) Shared Services Center, aims to characterize the biomarker fingerprint of the deep subsurface biosphere to advance the search for extraterrestrial biosignatures. The research will analyze lipid profiles from terrestrial...
This is a $852,867 research grant awarded by the National Aeronautics and Space Administration (NASA) to Arizona State University (ASU) to study the geochemical and biomolecular changes associated with the evolution of photosynthesis. The research aims to understand how geochemical changes may have enabled the historical rise of photosynthesis by examining transitions to photosynthesis in active hot spring ecosystems. The project will combine field research, laboratory analysis, and...
This is a $382,256 grant for research awarded by the National Aeronautics and Space Administration (NASA) to the SETI Institute, a non-profit scientific research organization in Mountain View, California. The grant is for a project titled "TOWARDS ACCURATE ROVIBRATIONAL LINE LIST FOR USE IN MODELING AND INTERPRETING OBSERVATIONS OF ISM AND (EXO) PLANET ATMOSPHERES: N2O" with a period of performance ending on July 20, 2026. The SETI Institute has previously held federal contracts and...
This is a $858,990.51 grant awarded by the National Aeronautics and Space Administration (NASA) to Portland State University (PSU) for research on the biological sulfur metabolism of methanogens, ancient microorganisms that emerged on the anaerobic Earth over 2 billion years ago. The grant, titled "DESCRIPTION OF KEY CENTRAL OBJECTIVES SULFUR ASSIMILATION AND TRAFFICKING IN METHANOGENS EXHIBIT UNIQUE FEATURES AS COMPARED WITH ALL OTHER EXTANT ORGANISMS, REFLECTING THE EMERGENCE OF THESE...
This is a grant award from the National Aeronautics and Space Administration (NASA) to the SETI Institute, a non-profit scientific organization, for a research project titled "Biosynthesis of 3-Methylhopanoids by Purple Non-Sulfur Anoxygenic Phototrophs." The project aims to investigate the cellular function of certain lipid biomarkers in purple non-sulfur bacteria and their potential implications for interpreting the geological record. The grant has a total ceiling value of $194,337.50 and a period of performance from June 3, 2015, to November 15, 2017. The research is relevant to NASA's Exobiology program and objectives related to understanding the phylogeny and physiology of microorganisms, as well as the evolution of genes, pathways, and microbial species. The award does not have a set-aside designation.
