TL;DR: The measured mass distribution tells little about the mechanisms of the fragmentation process, and two profoundly different models are studied, both of which agree qualitatively with the observed features.

TL;DR: This paper reports the discovery of a unique xenolith in the metal-rich chondrite Isheyevo, which has similarity with interplanetary dust particles (IDPs), but the volume of the xenolith is more than 30,000 times that of a typical IDP.

TL;DR: The skeleton of Coelosmilia sp. as discussed by the authors is shown to be entirely calcitic and its fine-scale structure and chemistry indicate that the calcite is primary and did not form from the diagenetic alteration of aragonite.

TL;DR: The radioactive isotope Fe-60 (T-1/2 = 1.5 Myr) was present in the early solar system by a single, nearby supernova and was inherited during the molecular cloud (MC) stage from several SNe belonging to previous episodes of star formation.

TL;DR: In this paper, nanoSIMS is applied to ancient carbonaceous structures to gain insight into their biogenicity and syngeneity, and the results demonstrate that sub-micron scale maps of metabolically important elements (carbon [C], nitrogen [measured as CN ion], and sulfur [S]) can be correlated with kerogenous structures identified by optical microscopy.
