Introduction: In recent years, a number of studies [1,2,3] have been published using data from the Lunar Prospector Neutron Spectrometer (LP-NS) to identify and quantify anomalously high hydrogen abundances near the poles of the Moon, which may be in the form of water ice. If water ice is indeed present at the lunar poles in high enough abundance, this(More)
Understanding of the geologic evolution of Mars has been greatly improved by recent orbital1–3, in situ4,5 and meteorite6–8 data, but insights into the earliest period of Martian magmatism (4.1 to 3.7 billion years ago) remain scarce9. The landing site of NASA’s Curiosity rover, Gale crater, which formed 3.61 billion years ago10within older terrain11,(More)
Introduction: We now have information from the fully reduced Lunar Prospector Neutron Spectrometers. Interpretation of these data yields distributions of rare earth elements (REE) Sm and Gd [1], major oxides and hydrogen on the Moon. Once both contributions of REE and major oxides are accounted for, we can construct the first global map of hydrogen(More)
[1] Water content and burial depths derived from thermal and epithermal neutron currents measured by the Mars Odyssey Neutron Spectrometer are used to determine north to south asymmetries and intercorrelations at high latitudes on Mars. Our goal is to contrast observed asymmetries with predictions based on current climate conditions and potential regolith(More)
AIMS To predict the risk factors for building infestation by Serpula lacrymans, which is one of the most destructive fungi causing timber decay in buildings. METHODS AND RESULTS The growth rate was assessed on malt extract agar media at temperatures between 1.5 and 45°C, at water activity (a(w)) over the range of 0.800-0.993 and at pH ranges from 1.5 to(More)
The Curiosity rover has analyzed abundant light-toned fracture-fill material within the Yellowknife Bay sedimentary deposits. The ChemCam instrument, coupled with Mastcam and ChemCam/Remote Micro Imager images, was able to demonstrate that these fracture fills consist of calcium sulfate veins, many of which appear to be hydrated at a level expected for(More)
Different mating systems have evolved in the fungal kingdom, including a tetrapolar multiallelic mating system in many basidiomycetes. In tetrapolar species, the presence of different alleles at two mating loci (MAT A and MAT B) is necessary for mating to occur. The tetrapolar fungus Serpula lacrymans causes wood-decay in buildings in temperate regions(More)
[1] Textural and compositional analyses using Chemistry Camera (ChemCam) remote microimager and laser-induced breakdown spectroscopy (LIBS) have been performed on five float rocks and coarse gravels along the first 100 m of the Curiosity traverse at Bradbury Rise. ChemCam, the first LIBS instrument sent to another planet, offers the opportunity to assess(More)
A suite of eight rocks analyzed by the Curiosity Rover while it was stopped at the Rocknest sand ripple shows the greatest chemical divergence of any potentially sedimentary rocks analyzed in the early part of themission. Relative to averageMartian soil and to the stratigraphically lower units encountered as part of the Yellowknife Bay formation, these(More)
