Genetic variance of adult human height shows a generally increasing trend across the birth-year cohorts but heritability estimates do not present any clear pattern of secular changes over a century.

Numerous related sample characteristics affect polygenic score performance, and incorporation of interaction effects increases both model and polygenic score performance.

The model organism Tetrahymena thermopile carries two nuclei with distinct genomes: an unrearranged germline genome with five chromosomes, and a somatic genome reduced in size by a third and with 181 chromosomes.

A previously unappreciated histone methylation pathway helps limit DNA double-strand break formation and recombination in heterochromatin during meiosis.

Two zebrafish Keap1-paralogs are equally adept at electrophile-sensing but manifest divergent and co-regulatory electrophile-signaling behaviors.

Gut microbial signatures of domestication parallel those of industrialization, implicating shared ecological drivers.

Brain functional connectivity shows a neurobiological predisposition to social bonding, and network-wide changes occur as a result of cohabitation in the prairie vole.

Transcriptional activation domains achieve rapid, dynamic, specific interaction with Mediator through binding of an unstructured peptide to multiple hydrophobic surfaces without particular amino acid side chain interactions.
