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

Decals on a wall at Oregon Contemporary read:

Only in silence the word,
only in dark the light,
only in dying life:
bright the hawk's flight
on the empty sky.
THE CREATION OF Γ‰A

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

Our week of finals go from Friday to Thursday this Fall.

I have an exam on Friday (10AM) and another on Monday (8 AM!) and then the last one on Thursday (not in the AM thankfully) 😬

Final gods were not happy with me this Fall. Well the last class has no final thankfully.

Should I watch ?

Rouge one was well-cast.
But the movie is fine.
There was so much acting talent.

Forest Whitaker as (unhinged/ falling apart) Saw Gerrera was the mvp.

if you are food insecure for both the humans and pets in your household there is a tool called Pet Help Finder that can help locate pet food banks nearby and other free or reduced price assistance and supplies for pets.
no one, ABSOLUTELY NO ONE, should have to give up their pet bc of this.
