This striped formation may contain the oldest intact rocks on Earth.* A new study suggests that they are at least 4.16 billion years old--relics from a time before plate tectonics, probably before oceans, even.

* The pocket knife is a more recent element. 🧪

Every study about vaccines that comes out is like "this vaccine is 97% effective at preventing this disease & also 3 other diseases & it somehow helps you play the violin beautifully" and antivaxxers are doing their own research that's telling them they can cure measles by eating polar bear liver.

Happy #FossilFriday from the BEST fossil shark specimen on display anywhere (it’s at KU)

This Cretoxyrhina mantelli skeleton has the bones of a big Xiphactinus audax mixed in with it, showing the shark died shortly after ingesting the absolute worst fish in the late Cretaceous seaway. 🧪🦈

What kind of AI governance do we need? Our new piece in @science.org answers this: we need policy grounded in evidence and built to generate more of it. Evidence-based policymaking is not a slogan—it’s a design challenge for democratic governance in the age of AI www.science.org/doi/10.1126/... 🧵
Advancing science- and evidence-based AI policy
Policy must be informed by, but also facilitate the generation of, scientific evidence

The great dismantling
The White House has instructed NASA to terminate two major, climate change-focused satellite missions. They've been collecting widely-used data, providing both oil and gas companies and farmers with detailed information about the distribution of carbon dioxide and how it can affect crop health.

What do fossils tell us about evolution? Kinda a broad topic...and I tried to give it a go in 20 minutes. Using dinosaurs and mammals as my guide (sorry foram and brachiopod fans!). Check out the video here:
