Catabolic pathway acquisition by soil pseudomonads readily enables growth with salicyl alcohol but does not affect colonization of Populus roots

The paper transfers a catabolic pathway for salicyl alcohol in Pseudomonas soil isolates, showing it enables rapid catabolism but does not confer a fitness advantage in rhizosphere competition.

Purinergic Preconditioning Induces Epigenomic and Transcriptomic Changes Resembling Epilepsy-associated Microglial States

This study shows ATP-mediated preconditioning induces epigenomic and transcriptomic changes in microglia-like cells that resemble epilepsy-associated microglial states.

Energetic costs of bill heat exchange demonstrate contributions to thermoregulation at high temperatures in toco toucans (Ramphastos toco)

This study measures the metabolic rate of toco toucans with and without bill insulation to assess the bill's role in thermoregulation at high temperatures, finding it significantly contributes to heat dissipation above the thermal neutral zone.

Repopulation of a 3D-simulated periapical lesion cavity with triggered osteoblastic-differentiated dental pulp stem cell spheroids.

This study demonstrates that osteoblastically differentiated dental pulp stem cell spheroids better repopulate a 3D-simulated periapical lesion cavity than monolayer cultures.

Phylogenomic Discordance in the Eared Seals is best explained by Incomplete Lineage Sorting following Explosive Radiation in the Southern Hemisphere

This study uses genome-wide sequencing to resolve the phylogeny of eared seals, finding incomplete lineage sorting explains phylogenetic discordance and supports a recent trans-hemispheric dispersal and rapid diversification.

Species delimitation and biogeography of the gnatcatchers and gnatwrens (Aves: Polioptilidae)

This study delimits species and infers phylogenetic relationships in gnatcatchers and gnatwrens, finding increased diversity and polyphyletic species, with biogeographic origins in South America.
