We’re very excited about the potential of IACS for advancing infectious disease research and believe this review from the Goda lab and its collaborators in @natrevbioeng.nature.com highlights its many powerful applications. Check out the full paper here: www.nature.com/articles/s44...
We found a new asymmetry in the large-scale chromosome structure: sister chromatids are systematically shifted by hundreds of kb in the 5′→3′ direction of their inherited strands! The work was led by Flavia Corsi, in close collaboration with the Daniel Gerlich lab. www.biorxiv.org/content/10.1... 1/
We’re excited to share our review: "Next-generation genetic screens in kinetoplastids", now published in NAR! It covers a range of perturbation methods—from RNAi to prime editing—as well as emerging assay technologies like scRNA-seq and image-activated cell sorting. academic.oup.com/nar/article/...
Next generation genetic screens in kinetoplastids
Abstract. The genomes of all organisms encode diverse functional elements, including thousands of genes and essential noncoding regions for gene regulation

Nature research paper: Chromatin loops are an ancestral hallmark of the animal regulatory genome https://go.nature.com/4kcNObU
Chromatin loops are an ancestral hallmark of the animal regulatory genome - Nature
The physical organization of the genome in non-bilaterian animals and their closest unicellular relatives is characterized; comparative analysis shows chromatin looping is a conserved feature of genome architecture and spatial genome regulation emerged early in animal evolution.
