We watched piRNAs and transposons across development, saw them dance tightly and wrote a paper about it. It's so cool to see it online and we will make a thread about it all very soon. Stay tuned :-)

New paper! How do RNAs "know" where to go inside a cell? We dug into the sequence elements that route RNAs to the right place. It turns out that, in mammals, they're surprisingly massive (>200 nt), multipartite, and wonderfully complicated. 🧵

The long reach of the Red Queen
Nature Reviews Genetics, Published online: 19 May 2026; doi:10.1038/s41576-026-00976-wRed Queen dynamics describe a mode of evolution in which interacting biological entities continually adapt and counteradapt. This Comment discusses the pervasiveness of these dynamics within genomes, which can involve selfish genetic elements, and highlights building evidence that they can even drive compensatory coevolution among subunits of essential protein complexes.

I’m thrilled to share that my PhD work has been just published in Cell. After a long and bumpy ride, we uncovered the core function of nuclear speckles -splicing of GC-levelled exons- and traced the evolution of this gene architecture and condensates themselves to amniotes.
Graphical abstract: Speckle-proximal and speckle-dependent RNA has short introns, and simultaneous emergence of multiple exons requires heightened concentration of spliceosome components.
Speckle-independent RNA has long introns and can be spliced well with or without speckles
Speckle dependent introns evolved in amniotes. The reduction in intron length was accompanied by the increase of the intronic GC content, giving rise to GC-levelled intronic architecture. This exon-intron architecture is not present outside of amniotes (Fish, Invertebrates), and these organisms lack nuclear speckles.
