The most viewed posts on Haldane’s Sieve in May 2013 were:

• The deleterious mutation load is insensitive to recent population history. Simons et al. use population genetic modeling and analysis of exome sequencing data to argue against an important role for population history in altering the burden of deleterious mutations in different human populations.
• Bayesian test for co-localisation between pairs of genetic association studies using summary statistics. Giambartolomei et al. present a method for testing whether association signals found in two studies are driven by the same genetic variant. An “Our paper” post is here.
• Our paper: The geography of recent genetic ancestry across Europe. This preprint from Ralph and Coop was formally published last month; they discussed their results in this post from last October.
• The role of twitter in the life cycle of a scientific publication. Darling et al. discuss the use of Twitter as a platform for scientific communication.
• Our paper: The rise and fall of the Phytophthora infestans lineage that triggered the Irish potato famine. Weigel and Burbano discuss a preprint on using genetic data from different time points to resolve the history of the pathogen that caused the Irish potato famine.
