I never thought I'd find an online system that would make the user experience of eRACommons look good in comparison, but here we are.

If you are submitting an NIH grant in February, you will be required to use SciENcv to prepare you biosketch.

IT IS MUCH WORSE THAN YOU CAN POSSIBLY IMAGINE.

Set aside *at least* 4 hours just to transfer an existing an biosketch into SciENcv.

Gene-specific selective sweeps are pervasive across human gut microbiomes - Nature Development and application of the integrated linkage disequilibrium score (iLDS) reveals both selective pressures impacting the human gut microbiome and the mechanisms by which gut bacteria adapt to ...

Grateful to share our paper on gene-specific selective sweeps in human gut microbiomes, now out in Nature! It has been a joy to work with @rwolff.bsky.social, whose insights and hard work made this possible.

Excited to share new work by Guli Agirman + co that identifies a direct mechanism linking gut microbial imidazole propionate to stress! 🧠🦠 Btw this image was made by Nano Banana Pro 🍌. First time I've gotten a model to accurately generate a science graphic 🤯 authors.elsevier.com/a/1mA5M6t8JE...

Paradigm shift is an over-used phrase, but that's what this really is with genetic manipulation of an unculturable bug. That changes microbiology.

Metagenomic editing of commensal bacteria in vivo using CRISPR-associated transposases Although metagenomic sequencing has revealed a rich microbial biodiversity in the mammalian gut, methods to genetically alter specific species in the microbiome are highly limited. Here, we introduce ...

Very excited to share our latest work in Science on metagenomic editing (MetaEdit) of the gut microbiome in vivo & directly modifying unculturable immune-modulatory SFB bug in the small intestine. 🦠🧬🛠️

Thanks for sharing. One reason old papers (pre-1980s) are more enjoyable to read is how expressive the language is. In my career, with maybe one exception, every paper I wrote has had its language sanitized, quotes removed, titles changed, and discussions hamstrung. I'm not sure to what end.

Happy to share this paper in final form rdcu.be/eH8tj, with more info on neuronal responses and potential mechanism of actions! The results suggest that there is neural interoception of microbial metabolic state 🧠🦠 We hope they can inspire more work in this area!

What might that other variable be? Well what makes people take acetaminophen for an extended period of time? Illness, infection, pain, lots of things correlate with use of these drugs.

1. There is increased risk observed with longterm exposure to acetaminophen.
2. But if you control using a sibling that was not exposed, the risk is the same for the unexposed and exposed siblings.
3. This suggests that the correlation is not due to acetaminophen exposure, but a different variable.

If you're a UCLA researcher (PI, grad student, etc) with an NSF, NIH or other suddenly suspended grant, please email or DM me.

I'm trying to confirm what the suspension letters say and how extensive the NIH suspensions are.

Breaking: NSF is suspending roughly 300 grants with UCLA, following a DOJ finding on Tuesday that the university violated Title VI by "creating a hostile educational environment for Jewish and Israeli students."

This is an elegant solution and really useful analysis!

I am seeking a postdoc for my group at UCLA. We work at the intersection of population genetics x microbiome (garud.eeb.ucla.edu). If interested, please message me!

”replication crisis” has always been hyperbole. Scientists ALWAYS argued, called each other frauds, and eventually land on consensus. A lot of what van Leeuwenhoek observed in the late 1600s was NOT REPRODUCIBLE because nobody could make lenses like him. But he was right, about cells, and bacteria.

I try to always acknowledge her when presenting genetics work in Bacteroides: because all the tools came from her lab. She was working on this stuff steadily and productively for decades, at a time when very few people were thinking about mammalian gut microbiota.

Xue lab at UC Irvine Ecology and evolution in the human gut microbiome

Hi friends new and old! I study how microbes interact and evolve in complex communities like the human gut microbiome.🦠🧬💩 I'm thrilled to share that I'm starting a lab at UC Irvine in April 2025 and am recruiting at all levels - please spread the word! kxuelab.com More about my work below...🧵1/n

Very cool. I was skeptical this could work in a complex community but looks like I was proven wrong! Maybe I need to get back on the hybrid selection train.
