Researchers reveal cellular architecture, phylogenetic position of protist Meteora sporadica

Meteora sporadica is a small, unicellular eukaryote (protist) that was discovered in deep Mediterranean sea sediments in 2002. It differs from known protists by the presence of two lateral arms that swing back and forth. ...

Microfossils shed light on the long fossil record of euglenoids

Hiding in the shadows, euglenoids are a fascinating group of single-celled protists that are neither plant nor animal. Plants photosynthesize, and animals eat. Euglenoids do both. Spiraling along the murky bottoms of shallow ...

Unraveling the role of supersulfides in regulating mitochondrial function and longevity

Supersulfides are gaining prominence for their occurrence as low-molecular-weight thiols or persulfidated cysteine residues, observed more frequently in both prokaryotic and eukaryotic cells. These compounds, which are characterized ...

Research reveals fission-independent compartmentalization of mitochondria during budding yeast division

A recent paper published in the Journal of Cell Biology by the Barral group (IBC) reveals that mitochondria establish diffusion barriers independently of physical separation. Constitutive inner membrane barriers and inducible ...
