The paper identifies a pH-controlled histone acetylation mechanism downstream of MITF that amplifies melanocyte differentiation by modulating chromatin dynamics.

The paper examines color pattern evolution in four bird lineages, showing plumage colors cluster along complementary color axes and that color variation is not constrained by phylogenetic relatedness.

The paper screens mosquitoes and March flies from northern Queensland for Mycobacterium ulcerans DNA and finds one positive mosquito pool and no positive March fly samples, with evidence of mechanical transmission via proboscises.

This study shows that T7 helicase can restart DNA replication from an RNA transcript without replication restart proteins or primase.

This paper introduces a mathematical model of HIV replication that includes both free virus and cell-cell transmission pathways, showing that cell-cell transmission suppresses latency and provides an evolutionary benefit to HIV.

This paper identifies WhiB4 as a redox-dependent nucleoid condensing protein in Mtb that links oxidative stress response with genome organization and gene expression.

This paper shows that the effectiveness of the β-lactam/β-lactamase inhibitor combination against Mtb depends on WhiB4-regulated redox changes, with higher mycothiol redox potential enhancing drug efficacy.

This study shows that 300 Hz sonic stimulation increases violacein production in Chromobacterium violaceum by up-regulating genes involved in glucose metabolism and tryptophan synthesis.

The paper introduces a method to quantify protein complex stoichiometry in live cells by diluting complexes in situ before single-molecule imaging, avoiding artifacts from detergent isolation or low expression levels.
