CI chondrite Oued Chebeika 002 links asteroids Bennu and Ryugu to common parent body

Meteoritics &Planetary Science, Volume 61, Issue 5, Page 801-818, May 2026.
Abstract CI chondrites are a compositionally primitive group of meteorites that have undergone extensive aqueous alteration, providing insights into the evolution of primitive planetesimals. Oued Chebeika 002 is the most pristine CI chondrite to date.

Ryugu reference project: Recommendations from the measurement definition team

Meteoritics &Planetary Science, Volume 61, Issue 5, Page 819-848, May 2026.
Abstract Sample return missions play a significant role in planetary science by providing pristine extraterrestrial materials. JAXA's Hayabusa2 and NASA's OSIRIS‐REx missions have returned samples from the C‐type asteroids Ryugu and Bennu, respectively. The chemical and mineralogical compositions of these samples closely resemble those of CI chondrites,

A Whole‐Genome Investigation of Mitonuclear Discordance in the Trematode Parasite Atriophallophorus winterbourni

Molecular Ecology, Volume 35, Issue 10, May 2026.
ABSTRACT Faster evolution of mitochondrial genomes relative to nuclear genomes creates selective pressure on nuclear genes involved in mitochondrial function to preserve mitonuclear compatibility required for energy production. In isolated populations, such coevolution occurs independently.

Doomsday or Multiverse Bias

Philosophy and Phenomenological Research, Volume 112, Issue 3, Page 608-616, May 2026.
ABSTRACT Bayesian epistemology faces serious challenges when dealing with self‐locating evidence. This paper argues that, given two modest assumptions about how confirmation should work (Patterning and Live Centers), Bayesianism faces an unavoidable dilemma.
