Our Wadjet-II paper by @roisnehamelinf.bsky.social is out in polished form: www.cell.com/structure/fu...

With a great preview by @kevincorbett.bsky.social & @amardeeep.bsky.social highlighting the potential of Wadjets:

Really excited to share our latest work led by @mattiaubertini.bsky.social and @nesslfy.bsky.social: we report that cohesin loop extrusion creates rare but long-lived encounters between genomic sequences which underlie efficient enhancer-promoter communication.

I am looking for phages infecting Streptococcus pneumoniae to test a phenotype - does anyone have some and willing to share ?

Repost appreciated :)

🧬 Ever wonder how metres of #DNA 🧬 fit into a single cell?

@gruberlab.bsky.social, working at @unil.bsky.social uncovered how protein machines fold DNA into loops – key for cell division & genome stability.

Excited to share a new preprint from the lab with @ryandhindsa.bsky.social ! www.biorxiv.org/content/10.1...

Led by @sherrynyeo.bsky.social, @erinmayc.bsky.social, and friends, we continue our journey to find viral DNA in our favorite place-- the overlooked and discarded reads in existing data! 1/
the treasure trove of all sequencing datasets

🔔Paper alert! Extremely excited to share a preprint from our lab! Spearheaded by @axel-schmidt.bsky.social, a super talented medical & computational geneticist, we studied latent Epstein-Barr virus (EBV) infection at population-scale.

Interested in how this works & what we found? Read along! 👇

Still a spicy question! Cohesin rings can hold sister mini-chromosomes (CEN plasmids isolated from yeast) together by "embracing" them. See beautiful work by Kim Nasmyth lab...

What happens on real chr is less clear & maybe more complicated... Calling in the real expert @dnatopologylab.bsky.social

AI just cracked de novo antibody design with a 100x leap! 🧪

Chai-2, a next-gen multimodal generative model, is shaking up protein design. With a 16% hit rate in fully de novo antibody design—over 100 times better than previous methods—it’s making drug discovery faster and more precise than ever.

This reveals parallels with DNA end protection in eukaryotes and highlights the challenges of having linear chromosomes as well as functional repair of DNA double strand break.

Maya, with help from Ania and Nicolas, figured out that the phage-encoded telomere resolvase TelN, which generates hairpin telomeres in the first place, also protects them from degradation by E. coli MR nuclease (but not B. subtilis MR). TelN associates with telomeric DNA and directly inhibits MR.
