Hi! We are looking for a PhD to work on the cross talk between transposable elements, insects and intracellular bacteria on the bioinformatics side. The PhD would be supervised by @mariefablet.bsky.social and myself along with @nicolasparisot.bsky.social Deadline December 2025! Please share! #tesky

Hi! Florence Hommais, @nicolasparisot.bsky.social , and I are looking for a postdoctoral candidate to investigate the molecular dialogue between three weevil species and their endosymbiotic bacteria #symbiosis! Please see the #post-doc offer for more information. #SymbioSky #Bioinformatics

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.

How does genetic architecture constrain evolutionary trajectories? To address this question, we inferred the genetic architecture of convergent plumage coloration and its evolutionary history in wheatears.
A mosaic of modular variation at a single gene underpins convergent plumage coloration
The reshuffling of genomic variation from multiple origins is an important contributor to phenotypic diversification, yet insights into the evolutionary trajectories of this combinatorial process and ...

Happy to share the results of a long-haul post-doc project, now online @science.org, aiming at understanding the rules of transgeneration epigenetic inheritance over TEs in plants and its extent and impact in nature. More below!
