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. 📸: Andy Moore, HHMI’s Janelia Research Campus

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...

NSF’s flagship fellowship program is rejecting applicants without peer review

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.

Cellular structure self-organizes through an interplay between internal mechanisms and external cues. The single-celled suctorian P. collini builds a trap structure to capture large prey using microtubule feeding tentacles, creating feedback between cell morphology and prey availability.

We have TWO papers out in @jcb.org this month! 🎉 First, @kirstin-rollins.bsky.social showed that macrophages nibble adherent target cells, like the ones found in solid tumors, instead of phagocytosing. Amazing movies from @sareenfiaz.bsky.social doi.org/10.1083/jcb....
