This study identifies a geothermal amoeba that divides at 63°C, setting a new upper temperature limit for eukaryotes and challenging existing paradigms about eukaryotic thermal tolerance.

This paper introduces Concanavalin A as a marker for nuclear envelope imaging in expansion microscopy, revealing diverse mitotic strategies across eukaryotes.

This study identifies Sfi1 family proteins as regulators of anterior-posterior centrin patterning in Stentor coeruleus, showing their role in regeneration and contraction through sequential recruitment during development.

This study identifies Brl1 and Brr6 as conserved fusogens mediating membrane fusion during NPC assembly in eukaryotes.

This study identifies SEP1, a septin in Chlamydomonas reinhardtii, as a coordinator of chloroplast protein import and division, showing its evolutionary conservation and functional interaction with TOC GTPases.

The paper develops a thermostable green fluorescent protein, Matcha, for live imaging in hyperthermophiles and uses it to study division ring dynamics in Sulfolobus.

The paper investigates how new centromeres evolve and become fixed in budding yeast by analyzing 138 species and 2,500 isolates, showing that kinetochore interface constraints influence centromere evolution.

This study identifies CLCC1 as a Torsin1A binding partner essential for nuclear envelope membrane fusion during NPC biogenesis, showing its therapeutic potential for DYT1 dystonia.

This paper demonstrates that cryo-ExM overcomes diatom silica barriers to enable high-resolution imaging and comparative cell biology across diverse diatom species.

Ultrastructure expansion microscopy applied to 221 cultured planktonic eukaryotes maps diverse microtubule and centrin-based cytoskeletons, including dinoflagellate apical centrin rings and cryptophyte cortical centrin meshes.

This study uses expansion microscopy to reveal unique sub-cellular structures in Candida albicans, showing a distinct SPB arrangement compared to Saccharomyces cerevisiae.
