“We cannot withdraw from the fact that over 1 million species of plants and animals face extinction.” IPBES remains committed to its mandate to provide the most credible science and evidence about biodiversity to all decision makers and actors. — @davidobura.bsky.social , @ipbes.net Chair

🇦🇺 Les forêts australiennes se dépeuplent à un rythme accéléré à mesure que le climat se réchauffe, selon une étude publiée dans la revue Nature Plants, s'appuyant sur des données recueillies sur plusieurs décennies. ➡️ u.afp.com/SXJC

It is freezing temperatures across Europe, including Ukraine (with temperatures decreasing to -20 this week). Russia deliberately targets infrastructure to leave people without electricity and heat. For what? To increase civilian suffering and deaths.

I invite all the foreign journalists who have asked me if peace is coming soon, as we have been promised after each round of negotiations initiated by President Trump, to go to Kyiv now. Listen to the explosions with us and gain a better understanding of what Putin thinks about these negotiations.

Our Union is not perfect, but it is a promise. That cooperation is stronger than confrontation. That law is stronger than force. Principles that apply not only to our European Union, but equally to Greenland.

Job alert! Farooq Ahmad is recruiting PhD students for his new research group in my department! He's looking for people interested in assisted migration of oaks to ensure climate and pathogen resilience for our future forests. Ad text is here, English at bottom: www.uni-kiel.de/personal/de/...

I absolutely love this card I received from @inrae-france.bsky.social ! "In 2026, let us sow science and harvest solutions!" That should be the core European 🇪🇺 spirit! To boldly go where no one has gone before.

🧬 New preprint on fungal effector 🍄🍎 We identify AvrRvi6, the first AVR from Venturia inaequalis. AvrRvi6 is a MAX effector with apoplastic activity, expanding the functional landscape of this major effector family. 📄 bioRxiv: www.biorxiv.org/content/10.6...

RIP Francis Hallé 🥲

Sweeping science cuts in 2025 halted clinical trials, erased public health data and forced researchers into impossible choices. “This year nearly broke me as a scientist,” one writes. Six researchers share their stories: buff.ly/u2MHIQo 🧪

We strongly condemn the U.S. decision to impose travel restrictions on five European individuals, including former Commissioner Thierry Breton. Link to full statement: link.europa.eu/NtMX4K

Yet again, another massive attack on Ukraine. All in the name of “peace,” apparently the same peace Russia claimed to want when it started the war. Truthfully, they do not hide their intention to destroy Ukraine.

Congratulations to Elodie Muller for her successful PhD defense on The ecological dynamics of an invasive pathogen: Cryptostroma corticale on sycamore maple. It's been a pleasure to supervise this work! @umr-iam.bsky.social and a big thanks to the jury members for the amazing discussions

The last PhD defense of the year! Congratulations Dr. Elodie Muller on your thesis on the #ecological #dynamics of an invasive #pathogen, Cryptostroma corticale, causing #SootyBarkDisease of #Maple trees! 👏👏👏👨‍🎓🎓🌳🍄📊📈 #ForestHealth #ForestPathology

Point of no returns: researchers are crossing a threshold in the fight for funding. www.nature.com/articles/d41... In my opinion, research in 🇫🇷 has already reached this tipping point for years.

Ravi que notre petit projet #MemoRust ait été retenu par #SuMCrop @inrae-france.bsky.social ! A l’interface phytopathologie–histoire des sciences et rurale, avec pour cas d’étude la rouille noire en France, nous analyserons les mécanismes de construction, transmission et oubli des savoirs.

On the CZ Day of the Fight for Freedom and Democracy we remember: rights aren’t given, they’re defended. The same holds for #forests – without active, 🧪 science-based care 🍁we lose 🌳 #biodiversity, 🌍 #climate-resilience and 🍄 #healthy-soils. Democratic freedoms let us protect these common goods.

The latent presence of Cryptostroma corticale (causal agent of the sooty bark disease) is widespread among French sycamore maple populations. Host density and water deficit seem to drive the silent spread of the pathogen. See our paper: doi.org/10.1111/ppa.... @umr-iam.bsky.social
