The origin and dispersal of the chicken across Eurasia is unclear. Here, the authors examine eggshell fragments from southern Central Asia with paleoproteomics to identify chicken eggshells, suggesting that chickens may have been an important dietary component as early as 400BCE.

Regulatory genetic variants repertoire in pig liver was expanded using RNA-seq, H3K27ac ChIP-seq, and DNA sequencing. These genetic foundations facilitate the dissection of molecular mechanisms underlying complex traits.

Recent findings implicating homeobox B13 (HOXB13) as a regulator of sheep tail length and their impact on sheep breeding via selection-based strategies and molecular genetics-based tools are discussed.

Are your mouse colonies in the best state to resume experiments? A short commentary on some key issues to consider when moving forward.

The SARS-CoV-2/COVID-19 pandemic has significantly increased the demand for specific-pathogen-free (SPF) nonhuman primates (NHPs) for development of vaccines and therapeutics, thus straining the supply of these animals for biomedical research studies. Non-SPF animals, which are available in greater numbers and include well-characterized primate species, should be considered in lieu of limited SPF animals for appropriate research studies.

Nonhuman primate (NHP) models, the most predictive preclinical models for human diseases and treatment outcomes, are in high demand and limited supply. There is a need for improved cryopreservation methods and routine storage of gametes and embryos, which are vital to protecting unique genetic models as well as providing resources for enhancing the genetic diversity of NHP colonies.

Genomic diversity is a driving force influencing human and animal health, and susceptibility to disease. During the Keystone Symposium on Leveraging Genomic Diversity to Promote Human and Animal Health held in Kampala on Lake Victoria in Uganda, we brought together diverse communities of geneticists with primary objectives to explore areas of common interest, joint technological and methodological developments and applications, and to leverage opportunities for cross-learning. We explored translational genomics research in farmed animals and humans, debated the differences in research objectives in high- and low-resourced environments, delved into infectious diseases and zoonoses affecting humans and animals and considered diversity and cultural context at many levels. The 109 participants were from 22 countries (13 in Africa) and included 44 global travel awardees from 9 countries, equal numbers of men and women, of whom 31 were students and 13 senior investigators.
