The Orange Cat Brain Atlas is here. 🧠🐈

Today, we published the first comprehensive cellular map of the orange cat brain. The new atlas reveals a single, specialized neuron responsible for behaviors like staring at walls, knocking objects off tables, and the 3am "zoomies."

Nothing is more rewarding than lab members' success. First medschool (USC) acceptance for the (now former) lab members. Proud and thankful PI!

(still feel a lot like the cat here these days)

I have opinions ... some conflicting.

Respecting your audience to me means treating them as folks who can process complexity and nuance to make better decisions. My current concern is the over-emphasis on "engaging" which has come to mean "entertaining". (Postman's book comes to mind).

No exaggeration, the vote split on this poll is hysterical.

Decals on a wall at Oregon Contemporary read:

only in dark the light,
only in dying life:
bright the hawk's flight
on the empty sky.

Happy holidays from our lab to yours
(Missing 3 folks in the photo).

It has been... well a year for research.

But proud and thankful for all we got done.

Two submitted GRFP proposals is the big highlight imho.

Doing a PhD is - at heart - one long discussion with your mentor. The discussion changes over time - with unexpected turns and ups & downs - but through it all is a pair of people discussing a topic endlessly to make sense of it.
PhD students: choose someone you like to talk to!

Almost sunset photo of the sky - trees and cars, beach beyond the parking lot.

Almost sunset photo of the sky - trees and cars, beach beyond the parking lot.

Good view (+ ok macchiato) after a long day (week) of exams / ongoing grading.

Happy end of the semester to all the educators.

Two nerve nets are formed in Hydra vulgaris: the endodermal (cyan) and the ectodermal (purple) net. (B) Intraepithelial neurons are randomly scattered between the epithelial cells of the two germ layers. (C) Two types of connections have been found between Hydra’s neurons. (D) Endodermal neurons are in physical touch with each other by forming neural handshakes by digiform endings, which get intertwined. (E) In other places, clusters of vesicles of different types can be released to mediate volume transmission between neurons and between neurons and other cells.

I guess this has probably already gone viral somewhere but I am simply dying at this picture of a bear that looks like it hired a photographer to do a glamour shoot
