The paper generates a multi-tissue RNA-seq atlas of adult medaka under salinity and seasonal contrasts to study gene-expression plasticity and comparative biology.

This study analyzes 42 genomes from Jomon hunter-gatherers to show they adapted to cold environments through positive selection during the Last Glacial Maximum.

The paper estimates the demographic history of the Jomon people using complete mitogenomes, revealing an effective population size increase during the Incipient-Initial phase not seen in present-day Japanese populations.

The paper investigates temperature-induced arrhythmia in medaka embryos, finding variation in temperature dependency of heart rate within the southern Japanese group.

The paper shows that CYP1B1 polymorphisms influence sexual dimorphism in medaka fish anal fin morphology.
