How good is MiniBWA, the successor to BWA? To test it, I ran MiniBWA on sequencing from 76 different species, comparing mapping speed, rate and accuracy with BWA MEM. In short, it's really good. If you map short reads, it's well worth your time. andrewcarroll.github.io/2026/06/30/t...

The Best of Both Worlds - Assessing MiniBWA

Recently, Heng Li released MiniBWA (GitHub) alongside a paper by Heng Li and Nils Homer describing the method (paper). MiniBWA builds on the approaches in Minimap2 (also by Heng Li), but falls back on...

What if you could improve small variant accuracy, CNV inference, and interpretability of your HiFi WGS data by taking a different approach to read mapping? Our new preprint describes portello, a method which demonstrates the potential for such improvements. (1/5)

Comparison of read mappings at HG002 chr4:40,294,825-40,295,700, showing conventional (pbmm2) read mappings (above) and portello mappings (below). The same set of unaligned input reads were input into each mapping process.

This blog talks about the great work of the @ebpgenome.bsky.social. To support it Google.org has funded sequencing and open release of 13 genomes, with a $3M commit to sequence 150 more and develop methods to improve assembly finishing and other bottlenecks. blog.google/innovation-a...

The killing of Alex Pretti is a heartbreaking tragedy. It should also be a wake-up call to every American, regardless of party, that many of our core values as a nation are increasingly under assault.

Incredibly moving Justin Trudeau remarks: "We have fought and died alongside you....During your darkest hours...we were always there. Standing with you, grieving with you, the American people....Canadians are a little perplexed as to why our closest friends and neighbors are choosing to target us."

Best resource for getting extracellular domain localization from Ensembl gene/protein IDs? I tried the subcellular locations in HPA but the membrane annotation is mostly fully intracellular proteins. 🧪🧬🖥️🔬
