Interspecific variations in adhesive protein sequences of Mytilus edulis, M. galloprovincialis, and M. trossulus.
Variation in the adhesive protein gene sequences of Mytilus edulis, M. galloprovincialis, and M. trossulus collected in Delaware, Kamaishi (Japan), and Alaska, respectively, was analyzed by the
The Process of Tholin Formation in Titan's Upper Atmosphere
TLDR
Evidence is obtained for tholin formation at high altitudes (∼1000 kilometers) in Titan's atmosphere using measurements from a combination of mass/charge and energy/charge spectrometers on the Cassini spacecraft.
Liquid water on Enceladus from observations of ammonia and 40Ar in the plume
This corrects the article DOI: 10.1038/nature08153
Electron precipitation and related aeronomy of the Jovian thermosphere and ionosphere
Voyager ultraviolet spectrometer (UVS) measurements provided the first unassailable evidence for particle precipitation in the Jovian atmosphere. Strong Lyman and Werner band emissions at high
Liquid water on Enceladus from observations of ammonia and 40Ar in the plume
Jets of water ice from surface fractures near the south pole of Saturn’s icy moon Enceladus produce a plume of gas and particles. The source of the jets may be a liquid water region under the ice
The tube cement of Phragmatopoma californica: a solid foam
TLDR
A model for the structure and bonding mechanism of the cement has the following major features: within the secretory pathway of cement gland cells, the electrostatic association of the oppositely charged proteins and divalent cations condense the cement proteins into dehydrated secretory granules; and after secretion, covalent crosslinking through oxidative coupling of DOPA gradually solidifies the continuous phase of the concrete to set the porous structure.
Cement Proteins of the Tube-building Polychaete Phragmatopoma californica*
The mineralized tube of the sandcastle worm Phragmatopoma californica is made from exogenous mineral particles (sand, shell, etc.) glued together with a cement secreted from the “building organ” on
The Cassini Ion and Neutral Mass Spectrometer (INMS) Investigation
The Cassini Ion and Neutral Mass Spectrometer (INMS) investigation will determine the mass composition and number densities of neutral species and low-energy ions in key regions of the Saturn system.
