How host and symbiont cells interface in intimately symbiotic associations is still poorly undersood. @annazaidmanremy.bsky.social and her team @inrae-umr-bf2i.bsky.social identifed now a complex network of membraneous tubules containing carbohydrates presumably feeding Sodalis symbionts of weevils!

Inspired by Van Gogh's famous painting, "starry night", this digital artwork shows microbes swimming in the "night sky" just like stars above rolling hills and a town.

FISH images of microbial cells in host organs/ tissues sometimes remind me of Van Gogh's starry night. Am I the only one? No? Yes? Maybe?
Anyways, I just wanted to recreate it ;)

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

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.

Hi! I'm restarting my project to cartoon and post about cool animal - microbe symbioses.
First up, Burkholderia bacteria, the symbiotic "superheroes" of Lagria beetles. I did my PhD work on identifying mechanisms that help this ectosymbiont establish in the host :)
