1/9 Metagenomics lets us read microbiomes in nature without cultivation, but writing (editing) them in their native context is still a major challenge.

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 ...

I love AlphaFold—but please include PAE (Predicted Aligned Error) plots for every “interaction.” Pretty PDBs ≠ proof. If the PAE doesn’t show an interface, it ain’t one. Show the plots. Structural biology's reputation is on the line.

Might not be the best use of limited funds, depending on what the structurally-based quesiton was!
Or: Just determine the structures (using constructs as predicted by AlphaFold)! 😇

Wesley Sundquist named in the ‘TIME 100 Most Influential People of 2025’ list - @theU
The honor is in recognition of the biochemist’s research to understand the structure of HIV that led to the drug lenacapavir, which is nearly 100% effective against HIV.

Asgard histones form closed and open hypernucleosomes. Closed are conserved across #Archaea, while open resemble eukaryotic H3–H4 octasomes and are Asgard-specific. More here: www.cell.com/molecular-ce...

Scientists often engineer microbes, like E. coli, to make drugs and other molecules.
But what if, instead, we could isolate ALL the components of a cell into little vials and sell them? How much would, say, 1 liter of cells be worth?
The answer, it turns out, is about $600,000.

I don’t know who needs to hear this but the CDC is being eviscerated right now. America is not going to have any kind of outbreak response capacity after tonight. Americans’ health data is no longer secure. Say goodbye to federal public health in any capacity. It’s a disaster. We won’t recover.
