In a new #openaccess PERSPECTIVE in #CYTOSKELETON, Ron Vale reflects on 40 years of #kinesin, from its serendipitous discovery to how this microscopic motor drove a revolution in single-molecule imaging. Read "Captivated by Kinesin" here: onlinelibrary.wiley.com/doi/full/10....

One year of the Aiken Lab! 🧫🔬🎉

It’s hard to believe how much we’ve built in our first year: new research directions, first papers, outreach initiatives, and an incredible team. Grateful to Sareen, Alejandra, Jacob, and Jay, and to our mentors and collaborators who have supported us along the way!

This mesmerizing timelapse captures the nonstop motion inside an animal cell. Red/orange streaks are the growing ends of microtubules, tiny “highways” that can rapidly assemble and disassemble to move proteins & other molecules within the cell.

What happens when marine embryos are crowded instead of isolated?

They become materials.

NSF's graduate research fellowship (GRF) program is designed to teach aspiring scientists how to write a winning grant proposal. So why are so many applicants being denied that learning experience? www.science.org/content/arti...

Getting asked about how academics can continue to do science & inspire trainees even in the midst of a continued (escalated) assault on science, reason, truth, & human rights. I don’t have great answers.

I would love to hear from mentors about advice they’re giving to trainees/ colleagues.

🚨The Neurocyto lab is branching out in our latest preprint! We used tubulin microinjection to directly visualize microtubule turnover in developing hippocampal neurons, demonstrating the presence of in-lattice repair and a selective stabilization in the nascent axon. Check below, or read on 🧵 1/9

Let's start 2026 with a @cellcommlab.bsky.social paper

How many branches is OK during #CellMigration?
It depends on the #cell: for ex. immune cells are just fine.
