Microtubules sustain the fidelity of cellularization in a coenocytic relative of animals

This study investigates cellularization in Sphaeroforma arctica, showing microtubules help guide plasma membrane furrows to ensure equal partitioning of nuclei and cytoplasm during division.

A geothermal amoeba sets a new upper temperature limit for eukaryotes

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.

Concanavalin A as a pan-eukaryotic nuclear envelope marker for expansion microscopy

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

Atonosomes, compartments involved in membrane tension decrease

The paper identifies atonosomes as tension-responsive plasma membrane-derived compartments in yeast, showing they form rapidly in response to membrane tension loss and are regulated by cell wall dynamics.

HAK-actin, U-ExM-compatible probe to image the actin cytoskeleton

The paper introduces HAK-actin, a probe for imaging actin cytoskeleton compatible with U-ExM, showing robust staining across human cells, microbial eukaryotes, and mouse retinal tissue.

An Advanced Mobile Laboratory to enable field-based microbial ecology and cell biology across scales

The paper introduces an Advanced Mobile Laboratory (AML) for field-based microbial ecology and cell biology, enabling multiscale analysis of environmental samples directly at the sampling site.

A self-organizing single-cell morphology circuit optimizes Podophrya collini predatory trap structure

The paper describes a self-organizing circuit in Podophrya collini that optimizes predatory trap structure through adaptive scaling of tentacle number and length.

Diatom ultrastructural diversity across controlled and natural environments

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

Charting the landscape of cytoskeletal diversity in microbial eukaryotes

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.

Hijacking and Integration of Algal Plastids andMitochondria in a Polar Planktonic Host

The paper tracks plastid and mitochondrial integration in a polar planktonic host over months, showing sustained benefits and highlighting a new strategy in plastid symbiosis.

A multicellular developmental program in a close animal relative

The paper shows that the ichthyosporean C. perkinsii undergoes symmetry breaking and cleavage divisions to form multicellular colonies with distinct cell types, suggesting ancient or convergent origins of animal-like development.

A mitochondrial redox switch licenses the onset of morphogenesis in animals

The paper identifies a mitochondrial redox switch that licenses the onset of morphogenesis in embryos by showing that mitochondrial superoxide production is critical for this transition.

Gradual evolution of cell cycle regulation by cyclin-dependent kinases during the transition to animal multicellularity

The paper identifies a periodic transcriptional program in Capsaspora owczarzaki, showing similarities to animal cell cycle regulation and suggesting an intermediate state in the evolution of cyclin-CDK systems.
