π€©Excited to share our new paper in @ScienceAdvances π ! We describe a new molecular mechanism underlying complementary sex determination in the Argentine ant π, involving a long non-coding RNA that we named ANTSR :) π https://t.co/VCXcdM0P93

Greenbeard effects in plants.
Have you heard about greenbeards? We just published an opinion piece on how this particular type of selfish genetic element could affect plant-plant interactions @NewPhyt @DEE_UNIL @AgapInstitut

Gut microbes can impact cognition and behavior, but whether they regulate division of labor in animal societies is unknown. We addressed this question using honeybees since they exhibit division of...

New paper on wound care in ants! Here we show that nestmates treat infected wounds more than sterile ones and that they use a battery of antimicrobial compounds to do so! This was a massive interdisciplinary project so let me tease it apart: (1/9) https://t.co/lDMerxkxfV

New paper out in @ScienceMagazine We report an extraordinary reproductive system in the yellow crazy ant. π Males of this species are all chimeras: they carry maternal and paternal genomes in different cells of their body.
science.org
A newly discovered mode of reproduction in ants results in males being chimeras of haploid cells from two divergent lineages.

Ants never cease to amaze. The latest and craziest in the saga of ant reproductive systems by @hgdarras and @KellerLab_Ants: males in the yellow crazy ant are chimeras of two distinct genetic lineages:
In this @ScienceMagazine perspective, @DanielKronauer discusses a new study showing that the males of an invasive species known as "yellow crazy ants" are chimeras of two distinct genetic lineages:

Congrat Katja!!! We are all happy to see this work out !!!
My most recent paper! Providing a rare example of functional validation at the nucleotide level, our results show that a SNP associated with life-history evolution in the fruit fly has remarkably large, pleiotropic effects on fecundity and viability https://t.co/2bZIfqoJFo

New preprint from the lab, in which nematodes related to C. elegans ambush ants, infect their head, and change their behavior. https://t.co/eripaHYSWJ. Lead by @ZimaiLi, with @ETF1989, T. Schmitt, @EconomoLab, F. Azuma, @DarrenJParker, T. Oliveira-Honorato, V. Bachmann

Back to France! After 15 years following ants in Lausanne, New York and Mainz, they finally led me to @IRBI_Tours, which I have newly joined as a @CNRS researcher. Excited to keep on studying the evolution and functioning of insect societies!

New paper out w/ @Shuping75138068 @yang_scotty @KellerLab_Ants and & colleagues. We show that the widespread longhorn crazy ant is likely native to the Indian subcontinent and that queens and males worldwide belong to two separate clonal lineages.π https://t.co/wvG7rNw0I6
