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.

I developed mRNA vaccines. RFK Jr is endangering US public health Katalin Karikó says the health secretary’s decision to pull research funding for the technology is akin to ‘dropping a bomb on the US’

Katalin Kariko won the Nobel Prize for mRNA vaccine technology. She is certain that RFK Jr is endangering public health by killing $500 million in mRNA research www.thetimes.com/us/news-toda...

How old is the earliest trace of life on Earth? A recent conference sees doubts raised about the age of the oldest signs of life.

A large slab with a fossil shark head and jaws, lots of clay pigeon sized and shaped shark vertebrae, and cranial elements and ribs of a giant toothy fish

A large slab with a fossil shark head and jaws, lots of clay pigeon sized and shaped shark vertebrae, and cranial elements and ribs of a giant toothy fish

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. 🧪🦈

Advancing science- and evidence-based AI policy Policy must be informed by, but also facilitate the generation of, scientific evidence

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/... 🧵

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:

A beautifully preserved bothremydid turtle from the Late Cretaceous Mooreville chalk of west Ala. We collected it in the late 1990s, and it's now on display at @Mcwane
w/many more wonderful fossils. (The specimen was found lying on its back plastron up.) Splendid specimen.
