Body-motion sensors can be used to study non-invasively how animals sleep in the wild, opening up exciting opportunities for comparative analyses across species.
Experiments showed that uniformly white sclera, one distinguishing feature of human eyes, facilitates gaze perception across species, suggesting that this eye feature evolved for conspecific communication in humans.
Allele-specific expression, natural antisense transcripts, and developmental gene expression, but not RNA editing or developmental hourglass, act in concert to shape the transcriptome during the fruiting body formation of complex multicellular fungi.

Relatively few genes have evolved vertically from the last universal common ancestor to modern prokaryotes, and phylogenetic analysis of these genes demonstrates a great genetic distance between Archaea and Bacteria.
Synechocystis switches its redox pools under reducing photomixotrophic conditions from utilizing NAD(H)- to ferredoxin-dependent enzymes and thereby balances its metabolism in a trade-off between energy conservation and chemical driving forces.

Developmental genetics of sea anemone mechanosensory neurons provides insights into the deep evolutionary history of mechanoreceptor development in animals.
Exceptionally preserved small shelly fossils (SSFs) from the early Cambrian Kuanchuanpu Formation (535 million years ago) reveal the muscular system of ancient cnidarians.
