Thrilled to share our work on the 🔥 single-celled predator Podophrya collini, which rewires its cell morphology to hunt more efficiently. Huge thanks to our amazing team—Amy, Lauren, Omaya, Marine, Mari, and especially Scott—for making this shine! ✨

How do cells adapt morphology to function? In a 🔥 preprint by @zjmaggiexu.bsky.social , with @dudinlab.bsky.social and @amyweeks.bsky.social , we identify a self-organizing single-cell morphology circuit that optimizes the feeding trap structure of the suctorian P. collini. 🧵 tinyurl.com/4k8nv926

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 ...

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

Thank you Eden!😜 You are so nice.

Congratulations to all authors! Happy to have contributed to the cryo-EM side. It was a lot of fun learning more about the herpesvirus DNA replication process and how clinical drugs inhibit it 🦠💊. Big thanks to @cijilim.bsky.social and Tahir for the support!

Wilkinson Lab We discover and study reverse transcriptases

The Wilkinson Lab is open for science! @mskcancercenter.bsky.social

🧬We'll be finding funky new RNA biology, mainly by looking at reverse transcriptases (i.e. the Best Enzymes In The World)🧬

annnd: I'm hiring - come join! Especially postdocs and PhD students - please get in touch (NYC is great)

Human RPA is an essential telomerase processivity factor for maintaining telomeres Telomerase counteracts telomere shortening by repeatedly adding DNA repeats to chromosome ends. We identified the replication protein A (RPA) heterotrimer as a telomerase processivity factor critical ...

Our paper in Science is out! @souravagrawal.bsky.social, @rlynn.bsky.social, @susvirkar.bsky.social, and the rest of the team show human RPA is a telomerase processivity factor essential for telomere maintenance. This reshapes our thinking about telomerase regulation. www.science.org/doi/10.1126/...

Antiviral reverse transcriptases reveal the evolutionary origin of telomerase Defense-associated reverse transcriptases (DRTs) employ diverse and distinctive mechanisms of cDNA synthesis to protect bacteria against viral infection. However, much of DRT family diversity remains ...

1/10 Genome maintenance by telomerase is a fundamental process in nearly all eukaryotes. But where does it come from?

Today, we report the discovery of telomerase homologs in a family of antiviral RTs, revealing an unexpected evolutionary origin in bacteria.

Barbara McClintock portrait

🧬🌽 Happy Transposon Day! 🌽🧬

Today we celebrate the birthday of Barbara McClintock - scientist extraordinaire and discoverer of jumping genes. Still the only woman to have an unshared Nobel Prize in the biomedical sciences #TransposonDay2025

1/10 New pre-print(s) from the Sternberg Lab in collaboration with Leifu Chang's Lab! We uncover the unprecedented molecular mechanism of CRISPR-Cas12f-like proteins, which drive RNA-guided transcription independently of canonical promoter motifs.

Excited to share a new preprint! Wireless devices use FM modulation to transmit multiplexed noise-resistant data. Led by @born2raisecell.bsky.social, we create a biochemical analogue of this paradigm using genetically encoded oscillators (GEOs) for single-cell FM streaming tinyurl.com/nbs8rw42 🧵
