Animals that eat poisons and don’t die Critters consuming species that contain deadly toxins have evolved a suite of clever strategies to keep out of harm’s way

Part of our work was highlighted here: "Animals that eat poisons and don’t die". Take a look and enjoy the great Amazonian snakes that feed on poisonous frogs 🐸🐍!! @rdtarvin.bsky.social

The new Wiley journal review system is an absolute nightmare. Editorial assistants have been replaced by a clunky, AI-enabled website that makes it harder to find and invite reviewers. Associate editor workloads have increased. I'm not convinced the invitations to reviewers are even going through.

"Your reps (esp. dems) are cut off from info. coming from fed agencies under the executive branch. They are learning about science cuts from us, or from the media, so when you learn about terminated grants, interference in free speech, etc, call or mail your reps to inform them."
