Pierre Chambon was one of the driving architects of modern molecular biology, whose scientific vision transformed the understanding of gene regulation in eukaryotic cells. His passing in May 2026 represents the loss of an extraordinary scientist. www.nature.com/articles/s41...

AlphaFold can now predict protein complexes at unprecedented scale. But once we have a predicted complex, the core question of how much we should trust the interface remains. Existing confidence scores are useful, but their meaning is not always obvious. #alphafold

Check out our new review about SAGA (Spt-Ada-Gcn5 acetyltransferase) and ATAC (Ada Two-A Containing) coactivator complexes in EMBO. doi.org/10.1038/s443.... We dissect the functions of SAGA and ATAC, which are crucial for understanding regulation by these complexes as targets in precision oncology.

Pierre Chambon was a great scientist. And a good man too. He alone opposed to leading British embryologists during the evaluation of a case of scientific misconduct more than 40 years ago, to defend young scientists against an establishment to which he belonged. An unforgettable lesson. RIP Pierre 💐

This story started during my post-doc with @tlaszlo.bsky.social while looking at TAFs isoforms for another project. Striking that a fundamental component of the basal transcription machinery can undergo such species-specific (rather drastic) evolutionary innovations. Thanks to everyone involved!

Intrigued by a long-standing conundrum in small RNA biology—how nuclear Argonaute proteins silence transposons when they *need* target transcription for their own recruitment—we studied the piRNA pathway. And found a hidden RNA-decay axis from Piwi to the RNA exosome.
