Variable responses of human and non-human primate gut microbiomes to a Western diet [PDF]
, 2015 BACKGROUND: The human gut microbiota interacts closely with human diet and physiology. To better understand the mechanisms behind this relationship, gut microbiome research relies on complementing human studies with manipulations of animal models ...

Advancing the Microbiome Research Community [PDF]
, 2014 The human microbiome has become a recognized factor in promoting and maintaining health. We outline opportunities in interdisciplinary research, analytical rigor, standardization, and policy development for this relatively new and rapidly developing ...

Advancing Drug Resistance Research Through Quantitative Modeling and Synthetic Biology [PDF]
Frontiers in Bioengineering and Biotechnology, 8: 583415 (2020), 2020 Antimicrobial resistance is an emerging global health crisis that is undermining advances in modern medicine and, if unmitigated, threatens to kill 10 million people per year worldwide by 2050. Research over the last decade has demonstrated that the differences between genetically identical cells in the same environment can lead to drug resistance ...

Adaptive tuning of mutation rates allows fast response to lethal stress in Escherichia coli
eLife, 2017 While specific mutations allow organisms to adapt to stressful environments, most changes in an organism's DNA negatively impact fitness. The mutation rate is therefore strictly regulated and often considered a slowly-evolving parameter.

Individual and collective identification in contemporary forensics [PDF]
, 2020 It has long been understood that individual and collective identification are inexorably intertwined. This convergence is not limited to genetics. This paper discusses the convergence of individual and collective identification in a comparative analysis ...

Global divergence of microbial genome sequences mediated by propagating fronts [PDF]
, 2005 We model the competition between recombination and point mutation in microbial genomes, and present evidence for two distinct phases, one uniform, the other genetically diverse. Depending on the specifics of homologous recombination, we find that global sequence divergence can be mediated by fronts propagating along the genome, whose characteristic ...

Relationship between fitness and heterogeneity in exponentially growing microbial populations [PDF]
, 2021 Despite major environmental and genetic differences, microbial metabolic networks are known to generate consistent physiological outcomes across vastly different organisms. This remarkable robustness suggests that, at least in bacteria, metabolic activity may be guided by universal principles.

Fecal microbiota transplants: Emerging social representations in the English-language print media [PDF]
, 2019 open access articleThis study investigates how English-language news sources have represented fecal microbiota transplants (FMT). FMT involves transferring stool from a healthy donor to a recipient with a dysfunctional intestinal flora in order to ...
