So cool! Work from cell bio colleague Dorothy Lerit's lab @lablerit.bsky.social, featured in MBoC!
From MBoC… Dorothy Lerit (Emory University) shows how cells choreograph RNA delivery to their division centers—keeping the process of cell division precise and on time.

Ten years ago, I saw a paper with some data that has bothered me ever since: B cells in a 0-100 ng/mL gradient of CCL19 are attracted to CCL19, but B cells in 0-500 ng/mL are repelled (see movie, ignoring the big clusters for now!). Why? Here's our model! doi.org/10.1101/2025...

While this does not excuse his other actions, for me it does illustrate the complexity of some human beings who can be truly dreadful in many ways and, yet, make some surprising and important positive contributions.

The leading edge of a crawling cell videoed through a microscope. Watch the actin cytoskeleton in motion as it drives membrane protrusion and cell movement. It’s like watching the cell think with its feet. #CellBiology
