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.

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"

A promising genetic treatment tailor-made for a baby born with a rare disorder For the first time, doctors have created a customized treatment using the revolutionary gene-editing technique known as CRISPR to treat a baby with a rare, life-threatening genetic disorder.

Look at this gorgeous chonk of a baby. Look at his lil face. We are treating his life-threatening ultra-rare genetic condition with super cool science. With a gene editing tool that we stole from bacteria! Just in case you also needed a reminder that humanity can still do some pretty awesome stuff.

Our primate T2T paper came out in Nature yesterday! It was a huge effort and I'm so grateful that I got the opportunity to work with this amazing group of scientists over the first two years of my PhD!

Sawfish: Improving long-read structural variant discovery and genotyping with local haplotype modeling AbstractMotivation. Structural variants (SVs) play an important role in evolutionary and functional genomics but are challenging to characterize. High-accu

Great to see that sawfish, our new HiFi SV caller, is accepted for publication in Bioinformatics! Sawfish emphasizes local haplotype modeling to improve SV representation and genotyping in both single and joint-sample analysis. Advance-access article now available: (1/n)

New @naturecomms.bsky.social paper reveals the hidden world of human pseudogenes, thanks to #PacBio HiFi sequencing. Researchers overcome short-read limitations to provide a more complete and accurate view of genetic variation and improve disease-linked variant identification. bit.ly/41zlRmJ

That's adorable!

Sequencing 101: Epigenetics - PacBio Epigenetics can impact everything from development to disease. See how PacBio HiFi sequencing technology is changing the game.

Epigenetics controls gene expression, but how do we see these modifications? Enter #PacBio Fiber-Seq—a groundbreaking method that maps DNA methylation & chromatin structure at single-molecule resolution. bit.ly/4gfQbrW

I wrote about a fun combinatorial problem I came across that is very useful in bioinformatics: Add marbles to k boxes, one at a time, independently, uniformly at random. How many marbles are needed for the probability that every box has at least r marbles to be at least p?

My first animation with the manim python package! Inspired by the following question: What is the probability that a triangle whose vertices are uniformly sampled from the surface of a circle contains it center? Do you know the answer intuitively?

You're absolutely right, the way I formulated it it could be misinterpreted. I corrected the statement, thank you! I think the "add characters anywhere" version is much harder, will be interesting to discuss it too (when I know how to solve it).

I wrote a post in my blog after 2.5 years. It's about a string problem I passed to my students long ago. It's also about DNA palindromes and a cool application of the KMP algorithm for prefix-suffix matching. Avoid this post if you suffer from aibohphobia.
