Out in Science Advances: Our #cryoEM structure of HFTV1, a virus infecting the halophile #archaea. *First full atomic structure (containing all structural proteins) of any tailed virus!* Congrats and thanks to all co-authors and our fantastic collaborators! www.science.org/doi/10.1126/...

Cryo-EM resolves the structure of the archaeal dsDNA virus HFTV1 from head to tail

This structure of an archaeal tailed virus (arTV) provides detailed insights into arTV assembly and infection mechanisms.

We are excited to share our preprint describing how Sulfolobus cells coordinate DNA segregation with cell division! In eukaryotes this type of regulation involves checkpoints and CDK-cyclins. But how does this work in archaea? This is the question we ask in our paper: www.biorxiv.org/content/10.1...

Temporal and spatial coordination of DNA segregation and cell division in an archaeon.

Cells must coordinate DNA segregation with cytokinesis to ensure that each daughter cell inherits a complete genome. Here, we explore how DNA segregation and division are mechanistically coupled in ar...

How do #apicomplexans reorganize their #PlasmaMembrane (PM) while replicating inside host cells? This study shows that #Toxoplasma recycles its PM via Rab5b- & MyoF-dependent #endocytosis, linking PM reservoir formation to membrane homeostasis via the micropore @plosbiology.org 🧪 plos.io/46tDxny

Formation and dynamics of the plasma membrane reservoir (PMR). The PMR forms prior to the development of the daughter cells’ IMC. Its position and size vary during replication, and it is reabsorbed at the conclusion of daughter cell budding. We propose that the PMR facilitates the expansion of the PM surface during replication. All scale bars represent 1 µm. While the PMR is not always visible due to its transient nature, virtually all the parasites undergoing replication are forming a PMR.

Seasonal biogeochemical variations in a modern microbialite reef under early Earth-like conditions - Communications Earth & Environment

Microbial communities, exposed to early Earth-like conditions in a modern microbialite reef, change cyclically due to seasonal environmental variations, implying evolved metabolic processes in microbialites over time, based on multiple chemical, physical, and biological analyses.
