Congratulations to Maria Corina Machado, recipient of the Nobel Peace Prize - her incredible optimism has already changed her country. I spoke to her, and wrote about her, at the beginning of this year:

I made a flyer! Know anyone in CA, OR, WA, or BC who might be interested in collecting mushrooms for research purposes? #mycology #citizenscience

Please share widely! 🧪 🍄‍🟫 🌲

A PDF version can be found here: drive.proton.me/urls/W1MM4FG...
A help-wanted poster seeking volunteer mushroom collectors in California, Oregon, Washington, and British Columbia. 

The poster provided some background info about the research project and study system and how folks can contribute if they are interested. 

REQUEST | Calling all mycophiles, naturalists, and citizen scientists in CA, OR, WA, and BC!

Going for a hike in the woods or a walk in your neighborhood park?
• Please keep your eyes peeled for the purple mushrooms of L.a-o!
• Collect the mushrooms* if you are able to access them safely.
• If you can, please take a photo of the mushrooms and the tree(s) you find them under.
*If you find a mushroom that is clearly rotten or moldy, please don't collect it.

"I collected some purple mushrooms. What should I do now?"
1. Please keep the mushroom fresh:
• Store in paper, not plastic.
• Keep cool/ refrigerate, but do not freeze.
• Store mushrooms away from light.
2. Email me to arrange pick-up, delivery, or shipment* of your sample.
* will cover packing and shipping expenses!

"What's in it for those who contribute to this work?"
• You will receive acknowledgement in presentations and publications stemming from this research.
• You will receive copies of journal publications from this research (data available upon request).
• You are invited to attend presentations of this research and to visit the lab at Stanford University. Page 2 of the help-wanted poster includes reference photos of the study organism and a map of where this species has been observed. All images and the map are sourced from iNaturalist.

Fred Ramsdell was parked at a campground in Montana on Monday when his wife suddenly started shouting. He first thought that maybe she had seen a grizzly bear. Instead, she had regained cell service and had seen a flood of text messages with the same news. “You just won the Nobel Prize!” she yelled.
Winning a Nobel Prize Interrupted His Off-the-Grid Vacation
Fred Ramsdell found out about his Nobel Prize nearly 12 hours after it was announced because he was on vacation in the Rockies.

One of the more incredible stories out of LA this year has been how a taco review blog became the best on-the-ground coverage of ICE raids in the city.

They do a dispatch every day, follow-up on the kidnapped people (which almost no media outlet has done), and fact-check government claims.

Bad Bunny was born in Puerto Rico, which is part of the United States. Ted Cruz was born in Canada.

Bad Bunny is eligible to run for president because he’s a natural born citizen. Ted Cruz is not.

Thought that was a fun little fact.
