Getting Rosalind Franklin’s story right is crucial, because she has become a role model for women going into science

What Rosalind Franklin truly contributed to the discovery of DNA’s structure
Franklin was no victim in how the DNA double helix was solved. An overlooked letter and an unpublished news article, both written in 1953, reveal that she was an equal player.

Check out this chemoproteomics tour de force from @stephanhacker2.bsky.social and colleagues — want to know which electrophiles label which amino acid residues proteome-wide? Finally, a comprehensive comparative study with a ton of insights on old and new warheads and optimized workflows. Bravo!
How can we study target engagement and selectivity of covalent inhibitors? Which electrophilic probes are best suited to study a certain amino acid?

Our study on "Profiling the proteome-wide selectivity of diverse electrophiles" is published in Nature Chemistry.(1/7)

Ever wondered why only a fraction of genomes encode CRISPR immunity? 🧬 🦠

Turns out CRISPR is rarely beneficial against virulent phages, being most beneficial against those for which resistance mutations are rare!

I'm very excited to share our manuscript for Cenote-Taker 3. We show that (1) CT3 quickly and accurately annotates previously uncatalogued virus genomes and (2) finds divergent virus genomes in contiguous assemblies. Virome benchmarks are SO hard, but I think we came up with clever and useful ones.
