☕ @majarad.bsky.social et al. show that phosphatidylinositol 3-phosphate (PI3P), produced by the phosphatidylinositol 3-kinase PIK3C3, is formed on ER domains after lysosome damage. ER domain PI3P helps to recruit the ATPase DFCP1, which promotes lysosome repair. www.nature.com/articles/s41...

Dear friends, take note of this position paper issued by the German Science Foundation on how to make the research ecosystem resilient against growing threats. Assuming this will blow over is a mistake. Academic freedom is an achievement of free, democratic societies that must be actively defended.
How can we protect academic freedom against growing attacks? A new position paper issued by a DFG Senate working group outlines how the resilience of research and the research ecosystem can be strengthened – and how policymakers, industry and society at large can contribute: sohub.io/aziq

A new, rather unexpected glycolipid class. Very well done study. Given how they look structurally, I think it makes a lot of sense to test these lipids against a panel of GPCRs. Lipid biology keeps surprising me. I like that. www.biorxiv.org/content/10.6...

Yale isn't just deciding whether to settle one investigation. They're deciding whether to cave to the Trump administration's campaign to use civil rights to control higher education. Yale has the resources to stand up for academic freedom. I hope they do(1/2) www.insidehighered.com/news/governa...
Deeply shocking, these White House draft regulations regarding federal funded research in the US, primarily aimed at advancing the interests of one individual. Hope 🇺🇸 scientists will make some coherent noise to divert a disaster that will undermine science & innovation in the US and far beyond
White House draft regulations could reshape federally funded research, including peer review and international collaborations. Learn what's proposed and why it matters. Comments due July 13. https://www.ascb.org/science-policy/white-house-draft-regulations-could-reshape-american-science/

Truly bizarre story of how two papers from the 1940s by physics pioneer Max Planck have been "retracted" from Naturwissenschaften, potentially by an algorithm, for anachronistic "plagiarism" issues, leaving the current editor baffled (but it is Springer Nature so.... www.science.org/content/arti...

Advice for @erc.europa.eu : Prohibit the use of LLMs for grant writing. Let applicants sign a declaration that they have not used such systems and that the text is written by them and them alone.

Proud to share a preprint of our paper on how bridge-like lipid transport protein VPS13C senses lysosomal membrane tension in anticipation of membrane lesions to initiate net ER-to-lysosome lipid transfer for efficient lysosomal repair www.biorxiv.org/content/10.1...
As ER-lysosome contact sites bridged by VPS13C have a gap width that cannot be resolved by light microscopy, we used a ratiometric approach to simultaneously trace fluorescence levels of ER-derived lipids & ER membrane proteins on the surface of damaged lysosomes containing pHrodo-labeled microbeads
