Large Carbonaceous Chondrite Parent Bodies Favored by Abundance–Volatility Modeling: A Possible Chemical Signature of Pebble Accretion

The Planetary Science Journal
Primitive meteorite groups such as the Vigarano, Mighei, and Karoonda carbonaceous chondrites have enigmatic patterns of elemental abundances, with moderately volatile elements—those that transition from vapor to condensate between ∼400 and ∼900 K ...

The Possible Crystallization Process in the Origin of Bacteria, Archaea, Viruses, and Mobile Elements

Biology
We propose a hypothesis for the simultaneous emergence of bacteria, archaea, viruses, and mobile elements by sequential and concrete biochemical pathways. The emergence process can be considered analogous to crystallization, where genetic and biochemical

Immature ovarian teratoma in a 20-year-old woman: A case report

Journal of International Medical Research
Immature ovarian teratomas are a rare subtype of germ cell tumours characterized by the presence of embryonic elements, particularly primitive neuroepithelium, and they typically affect young women. We report the case of a 20-year-old woman who presented
