To put this in perspective chestnut trees used to be dominant species in the United States. Billions of trees were killed by fungal blight and now fully grown America chestnuts are functionally extinct. There is no getting them back. Ever. All for a data center. www.gadgetreview.com/one-of-ameri...

One of America’s Last Chestnut Groves Is About to Be Destroyed for a Data Center
A rare 200-tree American chestnut grove in West Virginia may be cleared for data-center development, but the project denies the site is on its land.

I can't stop thinking how wrong the tech bros have understood creativity and creators. Or even just having hobbies. #erliart

The press coverage of the Academy of Natural Sciences has gone from "Oh how sad" to sounding like a hostage negotiation. Which maybe sounds bad, but elected leaders, the press, the people online, all saying "You don't have to do this, man" is better than mourning. share.inquirer.com/YTQg0s

Philadelphia shouldn’t give up on the Academy of Natural Sciences’ historic museum | Editorial
The Academy's 150-year-old building faces roughly $150 million in deferred maintenance costs. While that may seem daunting, it is not insurmountable.

I became a biologist because of a museum exhibit. Real artifacts tell stories that are more powerful than anything we can get from scrolling. They are part of our engine for training the next generation of scientists. 🧪 scienceforeveryone.science/the-awesomen...

The awesomeness of museums
Genuine artifacts tell the richest stories that fill our souls. And they fuel the scientific enterprise.

I visited La Brea and the Page for the first time last Sept. Even at 33, the wall of dire wolf skulls felt like a transformative experience. So much life and death all at once. Every one a real individual. I hope they keep it or something like it after the current renovations.

So glad you liked it! I also love that there's a pine cone quest in PoT 😆. Yet another reason to finally get around to playing it!

Carole Gee, (the late) Dick Dayvault, and I named a new fossil seed cone species, Pararacauria utahensis, and reconstructed it in 3D!

The Mississippian aged Edwardsville Fm. near Crawfordsville, IN is famous for crinoids. This piece is special because the anal tube (think waste chimney) was damaged and regenerated twice! The first time it split. The second is just starting to regrow. #FossilFriday #Fossil

It's another beautiful fall weekend in Eugene and these leaf fossils are right in season. Found in Goshen, Oregon, these laurel leaves fell over 34 million years ago but still look fresh enough to crunch. #FossilFriday #paleosky #paleontology
A long rectangular drawer is pulled out from a cabinet. In that drawer is a rectangle slab of what looks like concrete, about 2 feet long and 1 1/2 feet wide. The surface of the slab is peppered with about 30 red and brown prints of oblong leaves. A close up of a red leaf pressed into the concrete slab. The brownish red is vibrant. The edges of the leave are clear, and the black veins are crisp and visible.
