www.sciencedirect.com/science/arti... Great to see this excellent work led by Fen Zhang published! 🌱 Fen is now a postdoc with us at INRES Bonn; much of this work was done at Southwest University, Chongqing. Smarter N management = less NH₃ loss while maintaining vegetable yields. Congrats to all! 👏

KKRSU-001: The Missing Inventory Manager Inspired by the recent study @science.org Meet Rooty, Chef Chloro, Inspy, and Vivi, the first residents of the KRSU universe. Based on the work from @martinaried.bsky.social and @gabrielschaaf.bsky.social The science is real. The story is fiction🌱:-)
KRSU-001: The Missing Inventory Manager. Cartoon-style scientific illustration explaining phosphate signalling in plants. Rooty, a worried root character wearing blue overalls, frantically searches the soil for phosphate. Chef Chloro, a leaf chef, works in a kitchen above ground and asks whether phosphate is running out. Inspy, a small messenger character representing InsP8, reports that no inventory updates have been received. The office of Vivi (VIH2), the inventory manager responsible for phosphate-status communication, is empty and marked "Out of Office." The card illustrates the concept that loss of VIH2 disrupts InsP8 signalling, causing the plant to behave as though phosphate is scarce even when phosphate is available. The image combines fictional characters and storytelling with real plant biology inspired by a Science Advances study.

Congratulations to Borjana Arsova, Stefan Sanow, and everyone involved! Very nice work and thanks for letting me be part of it. Nice evidence that beneficial microbes can help plants thrive under nitrogen limitation, not primarily via N fixation, but by improving how plants acquire and use nitrogen.

Our dean at the Faculty of Agriculture Food & Engineering is the only dean @unibonn.bsky.social who wears a chain of office. This is a relict of the time before our faculty joined the University of Bonn in 1934 and was an independent Agricultural University. During that era it was the rector’s chain

Yesterday 25 years ago, the first human chromosome (chr. 22) was sequenced. Back then, sequencing of the second smallest chromosome took them almost 10 years!

Sequencing of the whole human genome was completed in 2003 at estimated costs of $ 2.7 billion. Nowadays you can sequence a whole human genome for less than $ 1000. To achieve an accuracy compareable to the 2003 genome sequence costs would be today around $ 10 - 20 million. bsky.app/profile/hoch...

There are already many articles for which there is more attention on Bluesky than on other comparable micro-blogging sites, meaning the academic community and the general public have clearly adopted Bluesky as one of its core places to disseminate and discuss new research. A Place of Joy.
