Considerable discussion surrounds the potential role of anoxygenic phototrophic Fe(II)-oxidizing bacteria in both the genesis of Banded Iron Formations (BIFs) and early marine productivity. However, anoxygenic phototrophs have yet to be identified in modern environments with comparable chemistry and physical structure to the ancient Fe(II)-rich(More)
A complete physical map of the 11p13 region containing the Wilms' tumor locus has been developed and used to localize a candidate Wilms' tumor gene. Our strategy to construct the map combined the use of pulsed-field gel electrophoresis and irradiation-reduced somatic cell hybrids. These hybrids, which contain limited segments of human chromosome 11(More)
In the low-oxygen Archean world (>2400 million years ago), seawater sulfate concentrations were much lower than today, yet open questions frustrate the translation of modern measurements of sulfur isotope fractionations into estimates of Archean seawater sulfate concentrations. In the water column of Lake Matano, Indonesia, a low-sulfate analog for the(More)
Some of the most efficient homogeneous catalysts for the low-temperature, selective oxidation of methane to functionalized products employ a mechanism involving CÀH activation [1] with an electrophilic substitution mechanism. Several such systems have been reported based on the cations Hg II , [2] Pd II , [3] and Pt II. [4] These catalyst systems typically(More)
Formohydroxamic acid / Acetohydroxamic acid / Advanced purex / Pu(IV) reduction / Hydrolysis / Electrochemistry / Actinide separations Summary. Simple hydroxamic acids such as formo-and aceto-hydroxamic acids have been proposed as suitable reagents for the separation of either Pu and/or Np from U in modified or single cycle Purex based solvent extraction(More)
The genes encoding the alpha chain of the human T-cell receptor have been mapped to chromosome 14, the chromosome on which the human immunoglobulin heavy chain locus resides. Thus, genes encoding two different classes of antigen receptor are present on the same chromosome. Furthermore, breaks involving chromosome 14 are frequently seen in tumors of T-cell(More)
It is has been assumed for over half a century that the earliest animals were obligate aerobes with relatively high oxygen requirements. However, the conserved biochemistry and widespread phylogenetic distribution of anaerobic energy metabolism in animals suggests a deep ancestral possession of the genes and enzymes necessary for a facultative anaerobic(More)
Acetic acid is an important petrochemical that is currently produced from methane (or coal) in a three-step process based on carbonylation of methanol. We report a direct, selective, oxidative condensation of two methane molecules to acetic acid at 180 degrees C in liquid sulfuric acid. Carbon-13 isotopic labeling studies show that both carbons of acetic(More)
