Antoni van Leeuwenhoek died #OTD in 1723.
A largely self-taught man in science, he is commonly known as "the Father of Microbiology", and one of the first microscopists and microbiologists. Van Leeuwenhoek is best known for his pioneering work in microscopy and for his contributions toward the establishment of microbiology as a scientific discipline. via @wikipedia

Went to Mountain "Lake" yesterday for a faculty retreat and I had to get some samples to look for microbes while I was there. Pretty epic mud.
The claim to fame of this lake is that Dirty Dancing was filmed here (when the lake was full). It is one of two natural lakes in Virginia and it has highly unstable water levels.

A patchwork pathway of apparently recent origin enables degradation of the synthetic buffer compound TRIS in bacteria
The widely used synthetic chemical 2-amino-2-hydroxymethyl-propane-1,3-diol (TRIS) was long considered to be biologically inert. Herein, we describe a complete degradation pathway for the catabolism of TRIS in bacteria.bioRxiv

Hi again #Mastodon!
I joined the fediverse when a lot of my community had not migrated from the bird site, so could only partially reconstruct it here using automated tools. If I followed you there and don’t here, say hi and let’s reconnect!
For those who don’t know me, I am a #virologist by training with almost 20 years of experience as a #science #editor, a passion for #microbiology and all science really, #OpenScience #openaccess & people
Have a lovely day everyone

Interesting: *Vaginal Microbiota Transplantation (VMT)*
We're probably going to start seeing a lot more of this as we appreciate how microbiomes of different organs impact health and disease.
Personally the key is to have clinical measures of success, as here, not just measuring % of different species changing.

Hello everyone!
I’m an associate prof at Virginia Tech studying viral diversity. Lately my group has been focusing on giant viruses, but we are also interested in other protist viruses, and the role of viral endogenization in host genome evolution.

Mycorrhizae and Land Plants – An Update
by Roberto
I am fortunate that among the first impressions of my day, I take in this view of land plants. Given my proclivity for microbiology my mind inevitably wonders to what I cannot see, the underground network of filamentous fungi connecting the roots of those plants, the mycorrhizae.

Fight not flight: parasites drive the bacterial evolution of resistance, not avoidance
In the face of ubiquitous threats from parasites, hosts often evolve strategies to resist infection or to altogether avoid contact with parasites. At the microbial scale, bacteria frequently encounter viral parasites, bacteriophages.bioRxiv

The methanogen core and pangenome: conservation and variability across biology’s growth temperature extremes
"Increased methanogenic growth temperature is associated with reduced genome size, and thermotolerant organisms...have larger core genome fractions, suggesting that genome size is governed by temperature rather than phylogeny. "

Scaling of Protein Function Across the Tree of Life
"The abundance of functional categories in a given genome scales with genome size, suggesting that universal constraints shape category abundance. Here we look across the tree of life to understand how genome evolution may be related to functional scaling. "

Scaling of Protein Function Across the Tree of Life
Scaling laws are a powerful way to compare genomes because they put all organisms onto a single curve and reveal non-trivial generalities as genomes change in size.bioRxiv
