7 years ago, I met a junior fellow named Jason Buenrostro who blew me away with a vision of futuristic genomic technologies

Today, we (Ajay Labade, Caroline Comenho) are excited to share our first steps into that future: Expansion in situ genome sequencing

What do you do when grants are cancelled, faculty searches are frozen, and the ability to do the science you believe in is slipping out of reach?

I wrote an essay. On efforts to solve aging with reprogramming, the primacy of the epigenome, and the path to rewriting our future:

maybe we just need more positive visions of what the future could look like if we develop mirror life

nothing cooler than watching a friend literally turn science fiction into reality

it's been awe-inspiring to watch @andrewcpayne.bsky.social and co build E11 Bio and prove that the FRO model can produce amazing, unique science

also expansion + molecular barcoding <3
🧪 E11 Bio is excited to share a major step towards brain mapping at 100x lower cost, making whole-brain connectomics at human & mouse scale feasible (🧠→🔬→💻). Critical for curing brain disorders, building human-like AI systems, and even simulating human brains.

Excited to see our T-cell exhaustion preprint published! This work is led by Tristan Tay and collaborators at AstraZeneca. See the sub-thread (reformatted for bluesky) originally composed and posted by the newly minted Dr. Tay

Degradation of IKZF1 prevents epigenetic progression of T cell exhaustion in an antigen-specific assay
Tay et al. demonstrate an antigen-specific assay producing exhausted T cells that reflect those found in human tumors. They identify IKZF1 (IKAROS) as a driver of exhaustion progression and validate t...

to shy posters, a reminder that you can literally just post about science you think is cool

& if you're looking for the next single-cell or spatial, I suspect single-molecule sequencing is about to blow up 👀

The single-molecule accessibility landscape of newly replicated mammalian chromatin
By developing a long-read sequencing method to simultaneously map replication status and protein-DNA contacts in cells, Ostrowski, Yang, et al. show that newly replicated chromatin is enriched for unw...

when you temporarily have more followers than your PI

(anyway @jbuenrostro.bsky.social is here now)

who knew it would be easier to get everyone to switch social media platforms than getting them to use hg38

seems like a fun game for all the scientists excited by the move but also mourning having to rebuild their following (it me)

I once made a meme to explain all of the drama surrounding the word "epigenetics" - to my horror, it is now used in at least several PhD classes
