Photochemical enrichment of deuterium in Titan's atmosphere: new insights from Cassini-Huygens [PDF]

, 2008
Cassini-Huygens data are used to re-examine the potential sources of the D/H enhancement over solar, measured in methane, in Titan's atmosphere. Assuming that the system is closed with respect to carbon, the use of constraints from the Huygens probe for ...

Fast‐scanning small‐angle X‐ray scattering of hydrated biological cells

Journal of Synchrotron Radiation, EarlyView.
Fast‐scanning small‐angle X‐ray scattering on biological cells in aqueous environments reveals intracellular anisotropy and orientation, and allows for systematic assessment of radiation damage caused by the measurements.Due to their high penetration depth, X‐rays enable us to obtain information from the interior of whole unsliced cells. Scanning small‐

THEO Concept Mission: Testing the Habitability of Enceladus's Ocean

, 2016
Saturn's moon Enceladus offers a unique opportunity in the search for life and habitable environments beyond Earth, a key theme of the National Research Council's 2013-2022 Decadal Survey. A plume of water vapor and ice spews from Enceladus's south polar

Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

Integrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it
