What if transposases are already transcription factors in disguise? Our new preprint shows that transcriptional regulatory activity is an intrinsic property of transposases, revealing a direct route for their domestication into transcription factors. www.biorxiv.org/content/10.6...

The last chapter of my PhD work is now live on MBE. This has been an incredible project, combining genomics, proteomics, as well as transcriptomics that resolves total mRNA from ribosome-associated mRNA (which we infer to be in the process of translation).

Had to draw a cartoon for this fascinating finding! Defensive fungal symbiosis on insect hindlegs: www.science.org/doi/10.1126/... #SymbioSky
A cartoon/ digital drawing summarising the findings of the paper "Defensive fungal symbiosis on insect hindlegs" by T. Nishino et al published in 2025. On the top left, a female Megymenum gracilicorne bug shows off symbiotic organs on the hind legs where she carries Ascomycota fungi. These were previously assumed to be Tympanal organs in these bugs but only females had them?; that didnt make a whole lot of sense to the authors...To the right of the bug is a row of eggs lying side by side. The paper shows that the bugs deposit the symbiotic fungi on the egg surface after egg-laying. Next on the image, fungal conidia grow on the egg surface. The eggs are pinkish in colour. A few fungi wear sunglasses like they are body guards. The paper shows that they protect the eggs from Trissolcus brevinotaulus, a parasitoid wasp, that likes to lay its eggs inside the developing bug's eggs. There are two wasps in this cartoon "eyeing" the fungi and looking frustrated. Eggs turn from whitish to pinkish within 10-days because they are reflecting the body colour of the nymph within the eggs.
