New #ISEPpapers #preprint! Regulated development of cannibalistic supergiant cells https://www.biorxiv.org/content/10.1101/2025.08.19.671124v2
"we describe a ciliate undergoing drastic morphological transformations... supergiants increase in size, change shape, and modify their behaviour to cannibalize clonal relatives."

Ciliates party hard in my hay infusion even on a Sunday morning.
Research reveals even single-cell organisms exhibit habituation, a simple form of learning https://phys.org/news/2024-11-reveals-cell-habituation-simple.html
Biochemically plausible models of habituation for single-cell learning: Lina Eckert et al. https://www.cell.com/current-biology/fulltext/S0960-9822(24)01430-1
"Earlier work found that a single-cell ciliate showed avoidance behavior, not unlike the actions observed in animals that encounter unpleasant stimuli."

Methanogenic #symbionts of anaerobic #ciliates are host and habitat specific https://academic.oup.com/ismej/article/18/1/wrae164/7737421 #ISEPpapers by @joro
"This study provides a clearer understanding of how anaerobic ciliates have evolved a mix transmission mode to both maintain and replace their symbionts over time"

A recent study has uncovered critical details about the association between anaerobic ciliates and methanogenic archaea, a relationship that has fascinated scientists for over decades. Researchers from the Faculty of Science, Charles University, and University of Rhode Island have used advanced genetic techniques and microscopy to study this relationship in 32 species of free-living anaerobic ciliates, primarily from the order Metopida.
Single-celled eukaryote employs unconventional cytoskeletal components for dynamic shape-shifting https://phys.org/news/2024-10-celled-eukaryote-employs-unconventional-cytoskeletal.html
Dynamic shape-shifting of the single-celled eukaryotic predator Lacrymaria via unconventional cytoskeletal components https://www.cell.com/current-biology/abstract/S0960-9822(24)01214-4
"the remarkable morphological change in #Lacrymaria involves a unique #actin-#myosin system rather than the Ca2+-dependent system found in other contractile #ciliates."
Recently, a research group led by Prof. Miao Wei from the Institute of Hydrobiology (IHB) of the Chinese Academy of Sciences discovered that Lacrymaria cells utilize unconventional and novel components of the cytoskeleton to achieve their remarkable dynamic shape-shifting ability. This study is published in Current Biology.
