Prevalence and Dynamics of Genome Rearrangements in Bacteria and Archaea
The genetic material of bacteria and archaea is organized into various structures and set-ups, attesting that genome architecture is dynamic in these organisms.bioRxiv

Advanced genetic techniques and microscopy offer new insights into anaerobic ciliate and methanogen symbiosis
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.Charles University (Phys.org)
Ran my way back from work at 3AM to streak out Archaea cells from a very generous collaborator. First round of plates are already cooking in the incubator - once we have data we'll know something about conserved genomic architecture dating back 250 million years. Exciting.

I'll be doing a lot more Halobacteria & Halococcus work in the near future, looking forward to sharing some interesting notes

Distinct life cycle stages of an ectosymbiotic DPANN archaeon
Abstract. DPANN archaea are a diverse group of microorganisms that are thought to rely on an ectosymbiotic lifestyle; however, the cell biology of these ceGaisin, Vasil A (Oxford University Press)
Happy to share the latest manuscript from our lab, in which we propose that eukaryotes evolved from a genomic chimera of Asgard archaea and giant viruses.

This is a controversial topic, but we believe we have strong evidence to suggest a critical viral role in eukaryogenesis.

Chimeric Origin of Eukaryotes from Asgard Archaea and Ancestral Giant Viruses
The details surrounding the evolution of complex cells remain some of the most enduring mysteries in biology.bioRxiv
Looking for some suggestions - I'm working with Archaeal genomic regions whose optimally fitting model seems to be Tamura-Nei (doi.org/10.1093/oxfordjournals…).
Would it be too much to suspect the Archaeal region is under similar types of evolutionary pressure?

Marine #microorganisms are crucial for #ocean health.
#Bacteria, #archaea, #fungi, #algae and #viruses make up most of the biomass in the seas and form the base of marine food webs.
They support nutrient cycling and drive crucial biogeochemical processes, including key steps in the carbon, nitrogen and silicon cycles.

‘Oceans are hugely complex’: modelling marine microbes is key to climate forecasts
Microorganisms are the engines that drive most marine processes. Ocean modelling must evolve to take their biological complexity into account.Tagliabue, Alessandro
While we are still trying to find ways to clean up problems like oil spills in the ocean, microorganisms in the seas have their own insights to impart.
Oil rich soil from the Guaymas Basin has provided German scientists understanding of a mechanism by which archaea in the Alkanophaga break down alkane molecules and thus degrade petroleum through oxidation.

A global virome of methanogenic archaea highlights novel diversity and adaptations to the gut environment
Mobile genetic elements (MGEs), especially viruses, have a major impact on microbial communities. Methanogenic archaea play key environmental and economical roles, being the main producers of methane -a potent greenhouse gas and an energy source.www.researchsquare.com
