In mice, epigenetic marks made on histones during infancy influence depression-like behavior during adulthood. A drug that reverses the genomic tags appears to undo the damage.

The cell type was discovered via single-cell RNA sequencing of thousands of cells in mouse and human airways and may play a role in cystic fibrosis.

The tails of polygamous deer mice sperm have longer midsections than the sperm tails of monogamous individuals of a similar species, and this correlates with improved swimming and competitive ability.
