Finally got to go through this carefully. An interesting paper and a tremendous amount of work. www.science.org/doi/10.1126/...

Excited to share our study out in @natcellbio.nature.com! Led by @mikelangelipid.bsky.social, we identify the first #LipidDroplet lipid quality control pathway: LD-localized FSP1 protects stored lipids from oxidative damage and prevents LD-initiated #ferroptosis. www.nature.com/articles/s41...

warmest congratulations to Scott Emr and Wes Sundquist for being awarded the 2025 World Laureate Association Prize in life science or medicine english.shanghai.gov.cn/en-Latest-Ta... WLA doesnt do a great job advertizing in the US so i am doing their job for them. So well deserved!

Now out in Science! Cyclin-dependent kinases (CDKs) are key regulators of the cell cycle. In @vcushing.bsky.social's magnum opus, we use #cryoEM to figure out how the CDK-activating kinase recognises CDKs to fully activate them - a key step in cell cycle control. www.science.org/doi/10.1126/...

🧠 The Lipid #Brain Atlas is out now! If you think #lipids are boring and membranes are all the same, prepare to be surprised. Led by @lucafusarbassini.bsky.social with Giovanni D'Angelo's lab, we mapped membrane lipids in the mouse brain at high resolution. www.biorxiv.org/cgi/content/...

See you there! Will try to throw a cytoskeleton party for my birthday 🎇

Beautiful live-cell imaging of lysosome tubulation along microtubules in this work just out from @lysoluis.bsky.social et al: rupress.org/jcb/article/...

Using cryo-ET, CRN Team Reck-Peterson showed that full-length LRRK2 can oligomerize on microtubules in its autoinhibited state. Both WT-LRRK2 and PD-linked LRRK2 mutants formed filaments on microtubules. 🔗 Read the full #preprint to learn more about their recent research: bit.ly/3VrVNaB

I'm very excited to share out latest work now published in Autophagy. www.tandfonline.com/doi/full/10.... This work was led by Dr. Devika Andhare and demonstrates the membrane binding and clustering capabilities of Atg11 using a new reconstitution system.

Excited to share our new review with @depaceraffa.bsky.social‬, @saikat2025.bsky.social‬, and Chad Williamson on the BLOC-1 and BORC complexes—key regulators of endolysosomal processes and linked to several genetic diseases. #NIH #Lysosomes #RareDiseases authors.elsevier.com/a/1lg4i8jWWJ...

👉 New publication ahead of print from our lab: tinyurl.com/ye7pntte We show that the protein SPG21, mutated in hereditary spastic paraplegia 21, localizes to endolysosomes via RAB7A, where it promotes mTORC1-dependent TFEB phosphorylation, reducing expression of a subset of TFEB regulated genes

big one! a decade in the making. nadler & team develop tools to track lipid transport in living cells at single-species resolution. turns out non-vesicular, asymmetry-driven transport is the main architect of organelle identity. feels like the dawn of a golden era for lipid biology. rdcu.be/eBGJv
