Esther Lederberg (December 18, 1922 – November 11, 2006) pioneered bacterial genetics, discovering lambda phage and F factor, inventing replica plating and furthered the understanding of the transfer of genes between bacteria by specialized transduction. She founded Stanford's Plasmid Reference Center. Despite groundbreaking work, she never got tenure and her discoveries are often credited to her Nobel laureate husband.
Hidden inside every growing hypha lies a microscopic powerhouse — the #Spitzenkörper.
It’s not just a blob at the fungal tip — it’s the traffic controller, architect, and GPS of fungal growth. 🍄
This video will uncover how this mysterious vesicle cluster orchestrates the very architecture of life beneath our feet.

I was very fortunate to collaborate with Jonatas Abrahao on this study, in which his group discovered a novel giant virus with remarkable morphology!
Few giant viruses with a tail have been characterized so far, but recent findings suggest that these structures may be more common than previously thought.

Giant endogenous viral elements in the genome of the model protist Euglena gracilis reveal past interactions with giant viruses
Giant viruses in the phylum Nucleocytoviricota have increasingly been found integrated into the genomes of diverse eukaryotes. Here we report 8 Giant Endogenous Viral Elements (GEVEs) in the genome of the microalgae Euglena gracilis.bioRxiv
Exciting work from the Hsu lab at Virginia Tech! They developed a cool way too knock down phage abundances to examine their role in the gut.
"A bacteriophage-conditional mouse model reveals the impact of phages within a conventionally colonized gut microbiota"
We found a really cool giant virus inside the genome of a green alga, and it has a very strange infection cycle that is hard to detect.
There are reports going back decades of viral particles spontaneously appearing in pure cultures of green algae, so this phenomenon seems quite common but mostly overlooked.
Wonderful discovery for #protists #independentresearch #microscopy #microbiology folks. Check out a new zine called "Amoeba Discovery":

I never thought very much about protists/amoebas, and reading this volume was a fascinating introduction to what seems to be an understudied field.
Now I'm wondering how I might isolate and sequence some interesting samples!
My at-home algal cultivation hobby is going well. I am surprised thst soil samples are the best for growing new green algae - more so than pond water.

Not a bad hair day for Phage 7-7-1
Noteworthy — While the phages χ and PBS1 attach to the flagella of their hosts via the tail fibers, phage 7-7-1 of Agrobacterium sp. H13-3 has another trick up its sleeve – or better: on its head (capsid). Noteborn et al. Found that phage 7-7-1 sports a bunch of dreadlocks on its head, proteinaceous fibers with which it attaches to host flagella.

Interesting perspectives on the microbiome here.
I always had the somewhat quaint idea that our guts are full of friendly microbes, but what if the microbiome is largely parasitic, at least in the long run?

Background Classifying viruses systematically has remained a key challenge of virology due to the absence of universal genes and vast genetic diversity of viruses.bioRxiv
Very nice study from Henshaw et al shows that #marine heterotrophic bacteria can sense and move towards cyanobacteria when the latter are infected with #viruses.
Presumably the signatures of early infection are a sign that nutrients from a lysed cell will be available soon.
This is a nice study that has implications for understanding the role of viruses in the #ocean.

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.

A newly discovered bacterium, Uabimicrobium helgolandensis, eats other bacteria and is a kind of 'bacteria of prey,' that should not even exist based on previous concepts about microbial cells. It could be a kind of microbial missing link, researchers suggest.

by Roberto — Phage-bacteria population dynamics can be remarkably complex. This is reflected in the natural history of both; new phage defense systems in bacteria and anti-defense systems in phage seem to be discovered daily. Behind these intricate strategies to help in the reproductive success of each lies the basic problem of any predator-prey relationship.
