Breaking: it's now official, the pro-EU D66 party came first in the Dutch election. Their best result ever.

The National Press Agency has just announced the final vote count. It’s a narrow victory with D66 just 15,155 votes ahead of the far-right PVV of Geert Wilders.
The most pro-EU party just won big in the Dutch election
D66 had a surprise surge, tripling their seats in yesterday's Netherlands election—and its openly gay leader Rob Jetten is set to become prime minister.

Ogechukwu (Mimi) Mbegbu, super star RA and resident FISH-ing expert showcasing her cytogenetic analysis of astrocytes undergoing telomere dysfunction at #ASHG2025. Lots of chromosomal chaos observed and a 3-fold bias towards acrocentric abnormalities?! Stay tuned for the mechanism

I had the opportunity to write an editorial for a piece in Neuro-Oncology (@neuroonc.bsky.social) executing a genomic analysis on perhaps the largest cohort of extracranial metastases of adult gliomas to date. Congratulations to the authors on this terrific piece of work! bit.ly/494Pz8s

This 7-year journey has reached a first milestone! 🥳 Excited to share our preprint (3rd of 2025) on the 3D telomeric interactome, a project that started with a K99 in 2018. Thanks to Yi-An Chen, first postdoc in our lab and first author who worked tirelessly to realize this dream. bit.ly/3W3wuMk
Mapping the Telomeric 3D Interactome with Telomere-C Reveals Repetitive Element Hubs Associated with Telomere Maintenance
Telomeres are essential for genome integrity, but the accurate, high-resolution mapping of their three-dimensional (3D) chromatin interactions, a process thought to mediate gene regulation and telomer...

New preprint! Deacon is a versatile tool for filtering FASTA/FASTQ files and streams at hundreds of megabases per second using minimizers, built with rapid metagenomic host depletion in mind, but equally useful for search.

Extracting @NCBI SRA files with fasterq-dump can require 17x the size of the accession while decompressing. Our new tool xsra extracts sequences at 5x throughput with significantly less disk usage, built-in compression, and optional BINSEQ outputs

1/ We made a tool called Vizitig to explore sequencing datasets visually, interactively, and with metadata.
It uses a colored de Bruijn graph under the hood.

🚨 Pre-print alert! 🚨

We generated chromosome-scale diploid genome assemblies for the widely used fibroblast lines BJ and IMR-90.

These models of replicative senescence and telomere shortening now have fully resolved telomeres, subtelomeres, and centromeres. 🧬
