Successful meiosis requires homologous chromosomes to pair and recombine to form crossovers, which are necessary for proper chromosome segregation. In this study, Li et al show how heterozygous inversions suppress these crossovers by altering the regulation of recombination.

Research Article
Microbiota can have a negative impact on lifespan of the model organism Drosophila melanogaster. In this study, Onuma & Yamauchi et al use a “fermented” fly diet to investigate the hypothesis that one specific species of microbiota shortens lifespan and disrupts gut homeostasis of aged flies.

Review
Lars Råberg reviews data from human host–pathogen systems to critically assess the evidence for a key assumption of models of host–pathogen coevolution—the presence of host genotype-by-pathogen genotype interactions (G×G).

Five new journals unified in addressing global health and environmental challenges are now ready to receive submissions: PLOS Climate, PLOS Sustainability and Transformation, PLOS Water, PLOS Digital Health, and PLOS Global Public Health
The COVID-19 Collection highlights all content published across the PLOS journals relating to the COVID-19 pandemic.
PLOS ONE is now accepting submissions of Lab Protocols, a peer-reviewed article collaboration with protocols.io, and Study Protocols, an article that credits the work done prior to producing and publishing results.
A collection of free training and resources for peer reviewers of PLOS journals—and for the peer review community more broadly—drawn from research and interviews with staff editors, editorial board members, and experienced reviewers.
PLOS Computational Biology's "Ten Simple Rules" articles provide quick, concentrated guides for mastering some of the professional challenges research scientists face in their careers.
PLOS Genetics welcomes several new Associate Editors to our board: Nicolas Bierne, Julie Simpson, Yun Li, Hongbin Ji, Hongbing Zhang, Bertrand Servin, & Benjamin Schwessinger
The former Natural Variation section at PLOS Genetics relaunches as Human Genetic Variation and Disease. Read the editors' reasoning behind this change.
Quanjiang Ji (ShanghaiTech University) joined the editorial board and Xiaofeng Zhu (Case Western Reserve University) was promoted as new Section Editors for the PLOS Genetics Methods section.
Congratulations to Associate Editor Michael Lichten and Consulting Editor Nicole King, who are newly elected members of the National Academy of Sciences.
Congratulations to Associate Editor Harmit Malik, who was awarded the Edward Novitski Prize by the Genetics Society of America for his work on genetic conflict. Harmit has also been elected as a new member of the American Academy of Arts & Sciences.
