Naegleria amoebae seek confinement and crawl persistently through narrow spaces

This study investigates how Naegleria amoebae navigate narrow spaces and environments, finding they use bleb-based motility and exhibit memory-guided movement that may aid in pathogenesis.

Changes in nuclear and actin mechanics from G1 to G2 affect nuclear integrity

This study shows that nuclear and actin mechanics change from G1 to G2, leading to decreased nuclear stiffness and increased vulnerability to rupture.

Myosin 2 drives actin contractility in fast-crawling species outside of the amorphean lineage

The paper shows that Myosin 2-driven actin contractility is present in Heterolobosea amoebae, not just Amorphea, and correlates with fast crawling.

Frog-killing chytrid fungi deploy different strategies to regulate intracellular pressure in cell types that have or lack a cell wall

This study shows that frog-killing chytrid fungi use different strategies for intracellular pressure regulation in cell types with and without cell walls.
