JUST IN: A federal judge has just ORDERED Llano County Texas to return "all books" that were removed from their libraries due to their content or viewpoint. Library patrons successfully argued that "content-based restrictions" were likely unconstitutional. The Texas judge is also prohibiting the officials from removing any more books while a lawsuit remains pending. The books that were banned included a book for teens that calls the Ku Klux Klan a terrorist group, Isabel Wilkerson’s “Caste: The Origins of Our Discontents” and a comedic children’s book with three stories from Dawn McMillan’s “I Need a New Butt!” series. The decision could set wide reaching precedent in light of recent book banning in Florida, supported by Ron DeSantis. What a great victory for books! 💙

If we think lithium is our key to surviving and curbing climate change we should be investing in desalination technology that harvests Li from the concentrated brine byproduct of desalination facilities, instead of ripping it from the earth and exploiting labor abroad.

Every 4 to 10 years, certain oak populations will synchronize to produce almost no acorns at all (starving off mammals), only to rain them down excessively the following year. This happens because only one in 10,000 acorns results in an eventual tree buff.ly/3oIHlK5

For the past several months, I’ve been investigating the case of the Arctic crab collapses. I interviewed observers, whistleblowers, fishermen, government officials, and marine biologists. Here is my published story and a thread of final thoughts: nautil.us/where-have-all-the…

You may not believe that your cat was born with a predatory instinct because it's a so playful critter, but it looks like cats are responsible for the global extinction of 33 animal species & responsible for the deaths of 6.9-20.7 billion mammals annually buff.ly/2s8mL91

Here’s one of the specimens being photographed - Bathypterois guentheri. Tripod fishes are unusual aulopiforme fishes with elongate pelvic and caudal fins. These prolongations are very stiff, which allows them to essentially stand motionless on the sea floor.

Found following a hurricane 😳. How can a piece of wood break through a tree like this?!? Is this a properties of matter phenomenon?!? A physics phenomenon?!? Does the species of tree matter?!? #ngss #ngsschat

The Molly Miller (Scartella cristata) or I like to call it, the "Punk Blenny" is very common in shallow (1-3m depth) Caribbean reefs and rocky shores. It usually lives in small holes and stretches its head out to eat food particles that pass by. #ichthyology

Anytime a republican wants to talk economy remind them, 22 of the 25 states with the worst economies, are republican controlled or dominated states. 22 out of 25 It's their incompetence that's dragging us down.
