My friends Betsy and Randy are in a tight spot.
Randy has glioblastoma; Betsy isn't able to work while caregiving.
If you are a person of means, w/ capacity to donate to their cause, it would really help them.
Our system is failing them; can our community help?

I'm grateful for my mental health.
I encountered someone *melting* down today. I had to step in to get them help. It was scary.
Our sanity is so contingent on the proper functioning of the big wad of wet gray meat in our skulls; doesn't take much for it not to work right.
Treasure your cognition.

More Greenland photos, featuring some geology. Scoresbysund has some fantastic exposures of columnar basalts, which are ~55 million years old (young for Greenland rocks!) related to flood basalts when the Atlantic was opening up. Fantastical shapes and fall tundra colors

For #MountainMonday, I'd like to express my gratitude that I can see both limbs of the Blue Ridge Anticlinorium from my campus. Here you can see PVCC nestled up against Carter's Mountain (eastern Blue Ridge geologic province):

Cool inset map from this "Geologic Map of the San Francisco Bay Region," by Graymer, et al. (2006). ngmdb.usgs.gov/ngm-bin/pdp/...
It shows the blocks of crust sliced & diced by Bay Area faults, and how much & in what direction they have moved in the past 34 million years.

Relying on ChatGPT to teach you about a topic leaves you with shallower knowledge than Googling and reading about it, according to new research that compared what more than 10,000 people knew after using one method or the other.

It’s fun to think about the surgeon who will botch your surgery 20 years from now and what he’s doing at this moment. He just ran all his homework through ChatGPT. He just read that article about vaccines and autism at the CDC website. He just watched an Instagram video about the moon landing hoax.

Speaking of bad science in media (and I am using the term "media" pretty loosely here), allow me to use The Daily Mail as evidence of why you should get your science information from reputable agencies rather than crap websites. I'm not going to link the article, but it looks like this:
