Two Possible Orbital Histories of Phobos

The Planetary Science Journal
The two moons of Mars, Phobos and Deimos, have orbits that are close to the Martian equator, indicating their formation from a circumplanetary disk. Phobos is currently migrating toward Mars due to tidal dissipation within the planet and may be disrupted

Plastome‐Based Phylogenomics Resolves Phylogenetic Complexity in Lysimachia and Reveals Unexpected Placement of L. thyrsiflora

Ecology and Evolution, Volume 16, Issue 11, November 2026.
We investigated the phylogenetic relationships and evolutionary history of Lysimachia using complete chloroplast genomes from four species. Comparative and phylogenetic analyses revealed conserved genome structure, identified variable regions as potential molecular markers, and detected positive selection in specific genes.
