Sexually dimorphic expression of multiple doublesex-related genes in the embryonic mouse gonad.
The only molecular similarity shown so far for sexual regulatory genes among different phyla involves doublesex (dsx) of Drosophila, mab-3 and mab-23 of Caenorhabditis elegans, and Dmrt1 ofExpand
Enumeration, isolation, and characterization of ultraviolet (UV-C) resistant bacteria from rock varnish in the Whipple Mountains, California
Abstract The in situ search for life on Mars requires an understanding of the possible habitats available and the types of microbes that inhabit such environments on Earth. Rock varnish is ubiquitousExpand
Terra Sirenum: Window into Pre-Tharsis and Tharsis Phases of Mars Evolution
Robert. C. Anderson, James M. Dohm, S. Robbins, B. Hynek, Jeffrey Andrews-Hanna, Jet Propulsion Laboratory, California Institute of Technology, Pasadena, CA 91109, University of ArizonaExpand
Space Science Opportunities Augmented by Exploration Telepresence
This document describes the conceptual and practical foundations of low-latency telepresence (LLT), opportunities for using derivative approaches for scientific exploration of planetary surfaces, and circumstances under which employing telepres presence would be especially productive for planetary science.

The northwestern slope valleys (NSVs) region, Mars: a prime candidate site for the future exploration of Mars
Abstract The northwestern slope valleys region is a prime candidate site for future science-driven Mars exploration because it records Noachian to Amazonian Tharsis development in a region thatExpand
Curiosity's Mars Hand Lens Imager (MAHLI) : inital observations and activities.
K. S. Edgett, R. A. Yingst, M. E. Minitti, M. L. Robinson, M. R. Kennedy, L. J. Lipkaman, E. H. Jensen, R. C. Anderson, K. M. Bean, L. W. Beegle, J. L. Carsten, C. L. Collins, B. Cooper, R. G. Deen,Expand
Error-Associated Behaviors and Error Rates for Robotic Geology
Humans are often blamed for errors in complex systems. A number of taxonomies exist for classifying human errors, but recent doubts have been raised as to whether these are actually errors or simplyExpand
Opportunistic Detection and Measurement of Novel Rocks
The Onboard Autonomous Science Investigation System (OASIS) evaluates geologic data gathered by a planetary rover and is used to identify new science opportunities during a rover traverse. Expand
