Genomes of animals as different as sponges and humans show conservation of global
architecture. Here we show that multiple genomic features including transposon diversity, …

How and at what pace bacteria evolve when colonizing healthy hosts remains unclear. Here,
by monitoring evolution for more than six thousand generations in the mouse gut, we show …

The objective of this study was to develop novel absorbable films suitable for use as a tissue‐engineering
scaffold for keratinocytes as a therapy for replacement of damaged skin. Poly(4…

Mitochondrial genomes of metazoans, given their elevated rates of evolution, have served
as pivotal markers for phylogeographic studies and recent phylogenetic events. In order to …

Gene duplication and deletion are pivotal processes shaping the structural and functional
repertoire of genomes, with implications for disease, adaptation, and evolution. We employed …

Gene duplication is an important process in the functional divergence of genes and
genomes. Several processes have been described that lead to duplicate gene retention over …

Experimental investigations into the rates and fitness effects of spontaneous mutations are
fundamental to our understanding of the evolutionary process. To gain insights into the …

DNA mismatch repair (MMR), an evolutionarily conserved repair pathway shared by prokaryotic
and eukaryotic species alike, influences molecular evolution by detecting and correcting …

The ecology and environment of the microbes that inhabit the mammalian intestine undergoes
several changes as the host ages. Here, we ask if the selection pressure experienced by …

Deoxyribonucleoside kinases (dNKs) are essential in the mammalian cell but their ‘importance’
in bacteria, especially aquatic ones, is less clear. We studied two aquatic bacteria, Gram-…
