Happy to share our latest work digging a bit more into what makes the the core microbiota of photosynthetic organisms convergent (or not!). Work performed @lipme-toulouse.bsky.social @cnrs.fr, in collaboration with @guan06rui.bsky.social @quadraminstitute.bsky.social tinyurl.com/3e958dt6 (1/10)

Environmental factors and microbe-microbe interactions drive the structure of the core microbiota of terrestrial microalgae

Plants and other photosynthetic organisms interact with their environment and surrounding microbiota through specialized associations. A global core microbiota has been proposed at high taxonomic levels, such as the order level. However, it remains unclear which environmental factors and how microbe-microbe interactions drive variation of this core microbiota at lower taxonomic resolution. Here, we leveraged the environmental diversity of 141 sites across the southwest of France to characterize algal populations, and their associated bacterial and fungal microbiota. We then performed a meta-analysis, combining these data with published datasets to formally identify the global core microbiota of terrestrial photosynthetic organisms, which comprises seven bacterial and five fungal orders. We next investigated diversity within this core microbiota and the environmental drivers shaping site-specific community composition. While environmental factors have a low impact on the total relative abundance of core orders, the core microbiota at the ASV-level is impacted by climatic factors, edaphic factors, and plant community descriptors. Using interaction network analysis, we finally explored how microbe-microbe interactions contribute to the assembly of stable core communities. Our results show that core ASVs occupy central positions in algal-associated microbial networks and that distinct core orders drive site-specific variation in core microbiota structure. Together, these findings highlight the importance of both environmental context and microbial interactions in shaping the composition and stability of the core microbiota associated with photosynthetic organisms. ### Competing Interest Statement The authors have declared no competing interest.

There are endless studies showing this and also the financial and societal benefits of universal basic income and or housing-first policies but the U.S. never goes for any of it because it would require allowing the poor to receive benefits that the rich consider “undeserved”

“A single-payer universal health care system could cover every American, save more than 100,000 lives a year, and still cost $1 trillion less than the system it would replace, according to a new preprint study led by researchers at the Yale School of Public Health.” ysph.yale.edu/news-article...

"Plant immunity research must start focusing on how pathogens respond to immunity, not just how plants deploy it." Fully agree. Nice to see our previous data helping make the case 😄 Always happy to help if anyone wants to set up a system like this! www.pnas.org/doi/abs/10.1...

Bacteria under ETI enter reversible stasis - not death. A dormancy driven by osmotic stress. This isn't just a detail. Plant immunity research must start focusing on how pathogens respond to immunity, not just how plants deploy it.

A massive update: At least ~15 companies~ are selling scientists antibodies using faked validation data. We've documented 18,000+ manipulated images on 17,000+ products sold by leading laboratory suppliers including Thermo Fisher, Abcam, Santa Cruz Biotechnology, Millipore Sigma and Bio-Techne. 1/🧵

This is what I think of when colleagues presume they are being responsible scientists by informing us they used AI for writing articles/chapters. 😬 *Don't use the fasho plagiarizing machine, ffs*

In case you are an academic who is currently being gaslit into believing that you're a caveman who wants their students to be jobless if you resist allowing AI in your classrooms... I present to you Berkeley Law's response, which can be summarized as "Fuck off directly into the sun."

Just had someone ask me why I was not on X. It is an ethical decision. It is a moral decision. Elon Musk is a monster. To give him or his products any traffic or business is an ethical and moral failing given the incredible amount of data that shows his abuses upon the world.

So we know AI helped a negligible number of students. But how many did it harm? I've crunched the raw data provided by the lead researcher, and what I've found is that ~9,500 students using AI studied less than even the *least* studious, non-AI using student. This should shock the conscience.

Both the Economist and others suggest this study demonstrates that AI can help students. So I contacted the lead researcher to figure out how many. Answer: Out of ~26,000 kids, a total of 20. And five months after starting to use AI, only four continued to spend 65 minutes on homework. Four.
