The most viewed posts on Haldane’s Sieve this month were:

• Efficient computation of the joint sample frequency spectra for multiple populations. Kamm et al. introduce new methods for learning about demographic history from the site frequency spectrum.
• Eight thousand years of natural selection in Europe. Mathieson et al. use ancient DNA to identify loci and phenotypes under selection in recent European history.
• Structured nucleosome fingerprints enable high-resolution mapping of chromatin architecture within regulatory regions. Schep et al. develop a new genomic method for assaying nucleosome positioning, and apply it to measure nucleosome occupancy in three species.
• Tandem repeat variation in human and great ape populations and its impact on gene expression divergence. Sonay et al. compare divergence patterns at short genomic repeats with divergence patterns in gene expression.
• The interplay between DNA methylation and sequence divergence in recent human evolution. Hernando-Herraez et al. study the evolution of DNA methylation in the primate phylogeny using bisulphite sequencing.
