Divergent Chemosymbiosis-Related Characters in Thyasira cf. gouldi (Bivalvia: Thyasiridae)
Within the marine bivalve family Thyasiridae, some species have bacterial chemosymbionts associated with gill epithelial cells while other species are asymbiotic.

متن کاملFirst Astronomical Detection of the CF Ion
We report the first astronomical detection of the CF (fluoromethylidynium) ion, obtained by recent observations of its J = 1 − 0 (102.6 GHz), J = 2 − 1 (205.2 GHz), and J = 3− 2 (307.7 GHz) pure rotational emissions toward the Orion Bar. Our search for CF— carried out using the IRAM 30m and APEX 12m telescopes—was motivated by recent theoretical models that predict CF abundances of a few × 10−1...
