About me: I'm a scientist and educator. I'm fascinated by our natural world and interested in how we best serve students in such rapidly evolving times. I'm also interested in crafts like woodworking and homebrew. I follow politics, perhaps too much. I don't post that much.

Ancient wolves on remote Baltic Sea island reveal link to prehistoric humans
Scientists have found wolf remains, thousands of years old, on a small, isolated island in the Baltic Sea—a place where the animals could only have been brought by humans.

It's my favorite day! It's the 38th anniversary of the Max Headroom signal broadcast intrusion!
1st incident lasted 25s during the 9PM news on WGN-TV in Chicago; The 2nd, 2hrs later, lasted ~90s on PBS affiliate WTTW during Dr. Who.

This is an amazing fact
8675309 is prime, and so is 8675311, so if you ever need a middlin'-large pair of adjacent primes to test your cryptographic suite, all you need is a 1980s earworm and a +2 and you're all set.
Man, everything is so bleak, anyone got a fun fact or little bit of trivia they want to share

School buses would make so much sense for V2G.. hope the technology continues to be developed.
Even without any V2G, seems likely that EV charging, by virtue of being a dispatchable load, is likely to be a net stabilizer of renewable-heavy electricity grids. In practice I imagine EVs will subsidize HVAC and other less shiftable sources of demand
Illinois utility tries using electric school buses for bidirectional charging
School buses are usually parked when the grid is under its biggest strain.

Can confirm.. wonderful thread. We would all benefit from sniffing more trees I think.
Ponderosa pine smells like butterscotch.
Go ahead, sniff one the next time you're in the western US. Some say "vanilla", some say "oh no, my nose is covered in sap."
Let's talk about birds, butterscotch, forest fires, blue wood, & boring beetles.
But mostly this thread is about terpenes.

Are there any outlets that are smart and worth reading on the right? I used to find the perspective of somebody like Noah Rothman worth listening to, but his recent appearance on the Commentary podcast, man just total intellectual bankruptcy.

I gotta say I find a lot of AI discourse around higher ed very confusing. "if ChatGPT can write your essays is college even worth it?" did people think math teachers were assigning problem sets because *they* couldn't figure out the answers?

Weird rabbit holes where you learn some real like this are the epitome of good social media IMO.
one of my favorite archaeology terms is "manuport" which just means a thing (rock, animal, stick, etc) that's in a weird place because a prehistoric human picked it up and carried it there. this one is estimated to be 3 million years old

He let snakes bite him some 200 times to create a better snakebite antivenom

These are amazing, such a unique intersection of different realms
I recently saw an amazing Navajo rug at the National Gallery of Art. It looks abstract at first, but it is a detailed representation of the Intel Pentium processor. Called "Replica of a Chip", it was created in 1994 by Marilou Schultz, a Navajo/Diné weaver and math teacher. 1/n
