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.

Here's a comic about a new approach to antibiotic-resitant bacteria I made for Louisiana State University with @fromthelabbench.bsky.social and @jpjordan.bsky.social #sciart

Read the full comic and learn more about the research on the LSU website: www.lsu.edu/winning-team...
Comic page about how bacteria are able to internally store just the right amount of iron to survive, and a new drug can block their storage which kills the bacteria. The story is centred around a doctor and patient, and athropomorphic bacteria.

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 :)
#SymbioSky
A cartoon with six panels. Lagria beetle eggs are protected from fungal pathogens by Burkholderia symbionts that produce antibiotics. The mother beetle smears then onto the surface during egg-laying. The symbionts are taken up by the larvae into dorsal surface "crypts" once they hatch.
