Gute Nachricht - Grüne, SPD und Linke verlassen X! Politische Debatte braucht fairen Austausch, der Menschen erreicht & informiert. X hingegen fördert zunehmend Desinformation & versinkt im Chaos. Macht mit & spread the word! Gemeinsam erreichen wir, dass die Bundesregierung diesem Beispiel folgt.

Screenshot-X-Post: X ist in den letzten Jahren im Chaos versunken. Politische Debatten leben vom Austausch, der Menschen erreicht & informiert. X hingegen fördert zunehmend Desinformation. Deswegen bespielen wir diesen Account nicht mehr.

In a rare show of unity, both R and D US lawmakers agree: the scientific publishing industry needs reform. Lawmakers are worried about the literature being flooded with 'AI slop' and the high open-access fees that some publishers charge. Read more @nature.com on this week's House Science hearing

US lawmakers intensify scrutiny of scientific-publishing practices

A congressional hearing covered the rise of paper mills and the costs of open-access publishing — but there was little agreement on what reform would entail.

I am thrilled and beyond grateful to receive a CNRS bronze medal this year - this is an incredible honour especially for an INRAE researcher like myself! A big thanks to my amazing team and the research community @RDP for all the great science we have done together!

Our first study on how the leaf succulent Kalanchoë laxiflora makes stomatal subsidiary cells is finally peer-reviewed & out - and it made the cover! 🌵 🧬 🔬 doi.org/10.1126/scia... Despite 150 years of evolution, grasses and Crassulacean succulents use the SAME gene to make subsidiary cells! 🤯

ONLINE COVER: Leaves of Kalanchoe thyrsiflora, a member of the Crassulaceae family of succulents also containing Kalanchoë laxiflora. Stomata, otherwise known as plants’ breathing pores, allow gas exchange between plants and the atmosphere, but little is known about how succulent stomata are formed or move. Cheng et al.’s investigation into K. laxiflora revealed that subsidiary cells can support the opening and closing of stomata and that the transcription factor MUTE, which drives stomatal development, also facilitates additional rounds of asymmetric division needed to generate subsidiary cells. Their work provides insight into succulent development and could be applied in agricultural contexts to engineer water conservation strategies.

© Miro LäderachThe MUTE gene switch is active in all cells of the developing stomata. Gene activity is visible through a weak signal (in blue) in the future helper cells and a strong signal (in green) in the mother cell of the guard cells.

🌵Preprint alert 🌵 5y in the works & extremely proud of this one. Xin Cheng & @heikelindner.bsky.social established the eudicot leaf succulent Kalanchoë laxiflora as a dev model. Like in grasses, MUTE makes Kalanchoë’s stomatal subsidiary cells! 1/n www.biorxiv.org/content/10.1... BSKY-tutorial 👇
