👇 Still a couple of days to apply to join our amazing team as a Research Scientist / Software Developer.

Apply if you want to build and maintain reproducible pipelines for large-scale genomic analysis to support our study of breast cancer cis-regulatory signatures and JASPAR, among other things.

The TFBS tracks for 8 species using JASPAR 2026 TF binding profiles are now available as native tracks on the UCSC genome browser @genomebrowser.bsky.social !

Mechanisms linking cytoplasmic decay of translation-defective mRNA to transcriptional adaptation Transcriptional adaptation (TA) is a genetic robustness mechanism through which mutant messenger RNA (mRNA) decay induces sequence-dependent up-regulation of so-called adapting genes. How cytoplasmica...

Ever notice that when one gene is disrupted, its orthologs get upregulated? This phenomenon, known as transcriptional adaptation, has been controversial and mysterious - glad to see that we are starting to learn how it works.

📢 Hiring! Our group @ncmbm.bsky.social seeks a Research Scientist contributing to:
• Reproducible pipelines for large-scale genomics
• cisreg signature analysis in breast cancer
• Continued development of JASPAR
• Cross-disciplinary collaboration

Looking forward to two days of talks and discussions around research and innovation in Life Science in Norway!

@uio.no

Let's get in touch then to see how/if it would work

Let me know if you plan to come to Oslo/Norway.

Looking forward to participating in this symposium! Thanks for the invitation.

We are thrilled to announce the first official release (v0.1.8) of #𝗯𝗲𝗱𝗱𝗲𝗿, the successor to one of our flagship tool, #𝗯𝗲𝗱𝘁𝗼𝗼𝗹𝘀! Based on ideas we conceived of long ago (!), this was achieved thanks to the dedication of Brent Pedersen.

Getting here wasn’t a straight path. We discussed the story behind the model, paper & API in the following roundtable: youtu.be/V8lhUqKqzUc

Thanks to
@ferhatay.bsky.social
and Aly Khan, we’re excited to announce a new chapter for RECOMB-RSG 2026. After years with ISCB/DREAM, we are transitioning to an official RECOMB satellite meeting (May 25 in Thessaloniki). recomb-rsg.github.io

RECOMB-RSG 2026
Deadline: Feb 15.
Tracks for: Preprints, Highlights (Recent Papers), Lightning talks
Details: recomb-rsg.github.io

This move supports a "discussion-first" format. As the field moves toward complex genomics and system-level integration, the community needs a venue designed for deep technical exchange and diverse perspectives.

You swear at the code.
You’re sure the computer’s being stupid.
But it’s not the computer. It never was. 🧵

inMOTIFin is now published in Bioinformatics! 🎉

It lets you generate random sequences and TF motifs, and insert motif instances with custom spacing, co‑occurrence and orientation. Use cases for de novo motif discovery, cooperative TF binding, and DL explainability.

Start your independent as an ELISIR fellow right after your PhD, in one of the most terrific places in Europe !

Some interesting points raised here. I'm personally in favor of applications to be evaluated for soundness and feasibility, followed by lottery.

Point of no returns: researchers are crossing a threshold in the fight for funding www.nature.com/articles/d41...

JASPAR recognised as an ELIXIR Core Data Resource - NCMBM - Norwegian Centre for Molecular Biosciences and Medicine ELIXIR has announced the life science data resources selected in its latest evaluation round for ELIXIR Core Data Resources (CDRs) and ELIXIR Deposition Databases. Among the six newly approved Core Da...

@amathelier.bsky.social from NCMBM, says: “ I am very proud to see JASPAR officially recognised as a Core Data Resource by ELIXIR and it is wonderful to see JASPAR join the ranks of other well-established European resources."

Recognition as an @elixir-europe.org Core Data Resource reinforces JASPAR’s role as a trusted, FAIR reference for TF-based gene regulation research.
Proud of this achieved milestone. A big thanks to all collaborators over the years and to the community.
