The paper investigates how molecular evolutionary rates in duckweeds correlate with acclimation strategies to high light, finding differences in mutation rates and metabolic adaptations between lineages.

This study shows that the NADPH phosphatase activity of Drosophila Mesh1, specifically the W138 residue, is essential for normal sleep regulation.

The study shows that VEN4 in Arabidopsis and SAMHD1 in humans both participate in DNA repair via homologous recombination, with VEN4 conserving this function despite differences in dNTP metabolism.

This study detects ppGpp in Drosophila and human cells and shows it induces metabolic changes, cell death, and lethality in Drosophila, establishing its role as an alarmone in metazoans.
