Our first paper in 2026 We worked on cornflower (C. cyanus) and mined metatranscriptomes of susceptible vs highly herbicide-resistant plants and discovered seq of previously unknown viruses (tentatively named cornflower partitivirus 1 & 2) enviromicro-journals.onlinelibrary.wiley.com/doi/10.1111/...

Where is coagulation factor VIII (FVIII) produced? After decades of research, the new data show that FVIII comes from liver sinusoidal endothelial cells located in zones 2 and 3 of hepatic lobules in mice and humans, with minimal expression in Zone 1 @rkaczmarekdr.bsky.social tinyurl.com/ydtaar2a

Bacteria associated with beetle increase the plant's emission of VOCs, incl. GLVs and benzenoids. The blend content & amount of induced VOCs in plants depends on the insect's developmental stage and the type of damage to the plant #insect #holobiont #microbiome link.springer.com/article/10.1...

"As HOLOBIONTS, insects are associated with diverse microbiota (Bacteria, Archaea, eucaryotic microorganisms, and viruses) that affect their fitness (positively or negatively)." Sidenote: microbes that do not impact fitness are also part of the holobiont www.nature.com/articles/s41...

Excited to share our new preprint co-led by @jnoms.bsky.social! Here we reveal an exceptional diversity of viral 2H phosphodiesterases (PDEs) that enable immune evasion by selectively degrading oligonucleotide-based messengers. This 2H PDE fold has evolved striking substrate breath & specificity.

1/ Transposable elements are often called "jumping genes" because they mobilize within genomes. 🧬 But did you know they can also jump 𝘣𝘦𝘵𝘸𝘦𝘦𝘯 cells? 🤯 Our new study reveals how retrotransposons invade the germline directly from somatic cells. www.biorxiv.org/content/10.1... A short thread 🧵👇

A very interesting day and still a few hours to go 🙂 We have a new team member - Diksha Kumari - welcome to our lab! 👋🙂 Moreover,we started the search for a signal from microcosm, namely from inside of cells in our samples,in cooperation with IBCH. We hope for interesting results!

Happy New Year! Good luck and FUN in 2025! 🥂🤗

Good piece by @natureportfolio.bsky.social. The erosion of thinking time—driven by admin, bureaucracy, industry agendas, and unrealistic output targets—stifles curiosity-led science. These pressures undermine innovation and the intellectual freedom vital for real progress. 🧪🌱🌍 #ScienceIsNotBusiness
