IF1 restrains excessive elevation of the mitochondrial membrane potential and safeguards the epithelial state of human iPSCs

Kaoru Kinjo, Gakuya Takamatsu, Kanako Toyama…·Masayuki Matsushita

This study shows that IF1 limits mitochondrial membrane potential elevation and prevents epithelial-mesenchymal transition in human iPSCs by inhibiting ATP hydrolysis.

Ancient Ryukyu Jomon contributed to past and current genetic structure of Japanese populations

Masatoshi Matsunami, Yosuke Kawai, Leo Speidel…·Ryosuke Kimura

This study sequenced ancient and modern genomes from the Ryukyu Archipelago to show genetic differentiation between Ryukyu Jomon and Hondo populations, with admixture occurring around 1,000 YBP.

Ancient genomes from the last three millennia support multiple human dispersals into Wallacea

Sandra Oliveira, Kathrin Nägele, Selina Carlhoff…·Mark Stoneking

The paper analyzes ancient genomes from Wallacea to show multiple human dispersals, with southern islands showing earlier Asian contributions than previously thought.
