The discovery of the first kinetochore proteins (CENP-A, CENP-B, CENP-C) was reported by Bill Earnshaw and Naomi Rothfield in 1985 in Chromosoma. Forty years later, Chromosoma/Chromosome Research has published a special issue (most articles are open access) link.springer.com/collections/...

40 years of CENP-A
In 1985, Earnshaw and Rothfield published in Chromosoma a landmark discovery of the centromere-specific protein CENP-A. Subsequent research has shown that ...

Absolutely thrilled to share the latest work from my lab focused on the variation and evolution of human centromeres among global populations! We assembled 2,110 human centromeres, identifying 226 new major haplotypes and 1,870 α-satellite HOR variants. www.biorxiv.org/content/10.6...

It's exciting to see the continuing legacy of T2T sequencing methods being discussed on @scifri.bsky.social ! 🧬 Complete genomes are helping us understand more and more about genetic function and diversity in areas of our DNA that were unreadable just a few years ago.

This was both fun and terrifying to tape! Awesome to talk with @glennislogsdon.bsky.social and @aphillippy.bsky.social about our sequencing data / paper, the improvements to large-scale sequencing projects, and what this means for our understanding of our DNA!

Complete genomes alert! @glennislogsdon.bsky.social, @christinebeck.bsky.social, and I were on @scifri.bsky.social today talking about "Complex genetic variation in nearly complete human genomes" 📄 www.nature.com/articles/s41... 📻 www.sciencefriday.com/segments/65-...

65 Genomes Expand Our Picture Of Human Genetics
Researchers closely examined the genomes of 65 individuals to paint a more complex, and more complete, picture of human genetic diversity.

Telomere-to-telomere DNA sequencing is set to transform the field of human genetics in coming years. For a flavour of what's coming, see this exciting work on nearly complete genomes of 65 individuals from diverse populations, out today in @nature.com by @glennislogsdon.bsky.social & colleagues. 👇🧬🧪

We updated our preprint describing chr21 centromere genetics/epigenetics in families with Down syndrome and general population! We found transgenerational methylation changes in a subset of families and that centromere size asymmetry is exclusive to T21! www.biorxiv.org/content/10.1...

We demonstrate a single-platform solution for complete T2T genomes on the ONT PromethION: Duplex + Ultra-long + Pore-C, aka "TNT" 🧨 Expecting rapid improvements in the coming year. Congrats @sergek.bsky.social @zbao.bsky.social @awngs.bsky.social @awngs.bsky.social @khmiga.bsky.social et al.!
