Based on feedback from applicants, reviewers and broader research community, the ERC Scientific Council decided to make changes in the 2026–27 calls for proposal for research funding.

🚨 Save the date! Thrilled to be co-organizing the next iteration of the @embl.org Symposium on the Cellular Mechanics of Symbiosis (📅 March 17-20), w/ @floravincent.bsky.social, @hassansalem.bsky.social & Tom Richards.

Last Wednesday, my first Ph.D. Student, Junchen Deng, defended his thesis! So proud!
Check some of the underlying papers - on planthopper phylogenomics doi.org/10.1111/syen..., origins of Auchenorrhynchan symbionts doi.org/10.1093/gbe/..., and planthopper symbiont evolution doi.org/10.1101/2025... !

The newly assembled planthopper-Bartonellaceae genomes range in size from <2 Mb to 158 kb. The one most reduced lacks any essential amino acid biosynthesis genes, contrasting with all other insect-associated bacteria with ultra-reduced genomes, or other genes with obvious importance to hosts! 2/2

New preprint from our lab! We show that #Bartonellaceae bacteria, mostly known as mammalian #pathogens, also colonizes #planthoppers. The planthopper #symbionts typically resemble related ant symbionts in nutritional functions, but show a much greater breadth of #genome sizes and functions. 1/2

Congrats all!

Highlights:
• Molecular records for Entomophthora’s new host clades from an unexplored bioregion - Greenland
• Confirmed high host-specificity of the pathogens;
• Provided the first records of bacteria seemingly associating with pathogen-killed flies;
• Validated multi-target sequencing approach

A new paper by our team @ioes-ju.bsky.social just published in J Invert Pathol @jinvertpathol.bsky.social!

In Diptera-#Entomophthora system, we show how simultaneously #sequencing #insect, #fungal #pathogen, and bacterial marker genes can aid biodiversity and biological interaction discovery.

The 2025-26 Eco-Evo job list is out. Good luck to those applying!

NEW PAPER, JUST OUT! 👀

Insects from the '70s and '80s were already collecting microplastic, decades before the term microplastic even existed. 🤯

A thread on the surprising history of this pollutant and the incredible insect larvae that helped us uncover it. 🐛

Let's dive in! 🧵👇 1/x

New preprint by our team @ioes-ju.bsky.social! Using custom multi-target amplicon sequencing on diverse pathogen-killed dipterans from Greenland, we find multiple #Entomophthora genotypes with notable host specificity, and reconstruct bacterial communities associated with the killed insects.

A convincing demonstration of a unique transmission strategy of a widespread #insect #endosymbiont

Thank you, @einsteinberlin.bsky.social, for recognizing the importance of raising concerns about scientific papers. Often, science sleuths face professional, personal, and legal threats.

Awards like these are vital to acknowledging the significance of our work.

How can long-term #ecology studies survive & resist political & social change, authoritarianism, war, but also embrace positive change?

Hardly new info, but BSky should know:

Warsaw's water quality is monitored by eight clams with magnets attached to their shells. If contamination in the water causes the clams to close, the magnets trigger an alarm and shut off the city's water supply.
Thank you, little guardian molluscs.
