Proud to share our single-cell transcriptomics approach for the microbiome by instrument-free split-pool barcoding - metaSPLiT, developed by the incredible @monochamussutor.bsky.social together with @gibbological.bsky.social, @cdiener.com, et al. at @isbscience.org

We sat down with Anika & Dmitry to discuss the new paper where we use bacterial scRNA-seq for studying bacterial phage infection and defenses. It turns out that bacteria use pre-existing variation in multiple layers of traits to protect themselves from unpredictable phages @isbscience.org

Pooled CRISPR screens with transcriptomics readout arrived for bacteria. We introduce mapSPLiT, an approach to profiling transcriptional responses to CRISPR perturbations at scale.

Estimation of diet from the metagenomics data is now possible! Curious to see how this can be applied for reanalyzing existing datasets to link the diet information with the data

What a stupid, petty move (rising to the top of the many many stupid, petty moves by this administration so far). Dispersing free HIV medication is one of the greatest unequivocally 'good' things the US does for the world. This program has saved 25 million lives. Why the fuck would you cut it?!

I think some people hear “grants” and think that without them, scientists and government workers just have less stuff to play with at work. But grants fund salaries for students, academics, researchers, and people who work in all areas of public service. “Pausing” grants means people don’t eat.

Finally caught up with some beautiful work from Alex Meeske in Nature! His lab has identified proteins in Listeria that either substitute for Cas in Cascade complexes (anti-type I-B CRISPR immunity) or degrade crRNA (anti-type VI-A CRISPR immunity). Inspiring stuff! www.nature.com/articles/s41...

We demonstrate that phages have co-opted cas genes from CRISPR defence systems, which subsequently evolved anti-defence functions.
