An ancient bacterial zinc acquisition system identified from a cyanobacterial exoproteome
Bacteria have developed fine-tuned responses to cope with limiting amounts of the essential mineral zinc.plos.io
Scientists have caught a once-in-a-billion-years evolutionary event in progress, as two lifeforms have merged into one organism that boasts abilities its peers would envy. Last time this happened, Earth got plants. The #algae Braarudosphaera bigelowii has been found to have absorbed a #cyanobacteria called UCYN-A, which may be a huge step forward for #evolution.

Two lifeforms merge in once-in-a-billion-years evolutionary event
Scientists have discovered that a once-in-a-billion-years evolutionary event is underway, as two lifeforms have merged into one organism that boasts abilities its peers would envy. Last time this happened, Earth got plants.Michael Irving (New Atlas)
Components of iron–Sulfur cluster assembly machineries are robust phylogenetic markers to trace the origin of mitochondria and plastids
The symbioses that gave rise to primary organelles are key events in the origin of Eukaryotes. This study uses a dataset of markers belonging to two conserved machineries responsible for [Fe-S] cluster biogenesis to support an early emergence of mito…plos.io
Chitin utilization by marine picocyanobacteria and the evolution of a planktonic lifestyle
This new research in Scientific Reports takes a #metagenomics and Q-PCR approach to explore the composition of the Cyanobacterial populations and their cyanotoxin production gene in major rivers across the United States (in 2019) and identifies Microcystis as the key toxin producing genus across this study.

The Early Microbial Colonizers of a Short-Lived Volcanic Island in the Kingdom of #Tonga https://journals.asm.org/doi/10.1128/mbio.03313-22
"We didn't see what we were expecting. We thought we'd see organisms you find when a glacier retreats, or #cyanobacteria, more typical early colonizer species—but instead we found a unique group of #bacteria that metabolize sulfur and atmospheric gases."
Rare opportunity to study short-lived volcanic island reveals sulfur-metabolizing microbes
In 2015, a submarine volcano in the South Pacific erupted, forming the Hunga Tonga Hunga Ha'apai island, destined to a short, seven-year life.Science X (Phys.org)
