My conversation with Zeb Miletsky about his book Before Busing about the Black freedom struggle in Boston:

We have a new paper out!

We looked at vesicle transport in cells. The textbooks say it's all motor-driven, but this idea is based on how large organelles are transported. Instead we find small vesicles move mainly by diffusion! We came up with a way to restrict the diffusion of one vesicle type (we made them furry!) & that reduces cargo delivery.

Congrats to my co-author Méghane Sittewelle who did all the imaging magic!

Alright, so, I am finally here and totally late to the party but I'm here!

Here's an amoeba imaged by scanning electron microscreepy!

In the endless discussion of #Mastodon over #Bluesky (which, btw, really, we all should move on if not away from it and it would be about time), I am amazed bout the quantity of people posting (on Mastodon) that scholars post more on Bluesky than here, bc (insert whatever feature of Twitter).
Maybe it's bc I'm tired and sleepy today, but considering the endless stream of complaining here, wouldn't it be better for the #AcademicFedi to stop comparing and start posting about their work?

Very cool preprint from the Fritz-Laylin lab - "Genetic transformation of the frog-killing chytrid fungus Batrachochytrium dendrobatidis" https://www.biorxiv.org/content/10.1101/2023.10.17.561934v1

Here's a closer look at the cell division fail from yesterday. The contractile vacuole network gets distributed through the cell during division- here you can see tubules converting to bladders that pump unusually synchronously

These are the cells that created yesterday's maximum intensity projection! Featuring one failed cell division, and one successful cell division. Lots of contractile vacuole activity.

“Graduate student mentorship as a target for diversifying biology.”

Girish Kale and Reinier Prosee cover a recent preprint from researchers #UCBerkeley. Particularly excited to note the positive impact of informal mentorship & being part of interdisciplinary groups that the students report as part of this study. #preLightsPeerSupport

I got to play with a very cool microscope today!
purple: actin
orange: mitotic spindle

A twirling flagellate

I wanted to consolidate a few thoughts on google, misinformation, large language models, enshittification, and the fate of the web as we know it.

It started when Carl Zimmer shared this remarkable example of Google being fooled by machine-generated bullshit online.

It's #MicrosCreepy season!
Here's an experiment that went horribly wrong

Gummy worms!

... or the tracks of cells before (green) vs after (orange) being squashed to a 5 micron ceiling. They tend to crawl faster when squished. Circles are the pillars holding up the ceiling.
