Two great new studies out in @nature.com today, pushing back the recovery of dental enamel proteins to 21+ million years in the Arctic (www.nature.com/articles/s41...) and 18+ million years in East Africa (www.nature.com/articles/s41...).
Eighteen million years of diverse enamel proteomes from the East African Rift - Nature
The isolation of dental proteins from fossils deposited 1.5 million to 18 million years ago in the Turkana Basin in Kenya, a tropical region, demonstrate the promise of dental enamel for palaeoproteom...

I live rent free in Joe Rogan's head. Today marks the 10th JRE episode he's mentioned me on. But he won't have me back on. He's allergic to real evidence

The Aftermath of Speaking to Graham Hancock on Joe Rogan has now been ported over to Spotify. open.spotify.com/episode/7rMV...

Wild how the minute the “liberal arts degrees are a waste of time” people get a hold of the government they immediately start doing the stuff a liberal arts degree teaches you not to do because it ruins civilization.

A blue Tesla Model 3 has been crushed by an Olmec statue. A man with long black braids leans against the hood of the car with his arms crossed, staring down the camera.

So pleased to see Charlotte Blacka's first 1st author paper: innovation was to use tims-TOF #MS for rapid sex estimation method based on amelogenin #palaeoproteomics. At <20min per sample (including prep all the way to data processing), this enables far higher sample numbers: doi.org/10.1002/rcm....
Summary of methodological and analytical variables applied to the three different sets of sample material discussed. Each coloured background represents differences in variables: in green, sampling; blue, acid etching approach; yellow, MS instrument; purple, timsTOF run length.

His seminal work on oxygen isotopes in calcified tissues alone was impressive, but he did much more. While v genial, he was not afraid to speak his mind. Some of us vividly recall him banging the desk at a meeting in Paris & proclaiming “This is notta science, its‘a fairy story”

For isotope geochemists out there-

Just heard the sad news that Professor Antonio Longinelli, one of THE great 20th C isotope geochemists passed away yesterday. He was almost 95 and still on the button.

I expected this CNN article would be sensationalistic. I appreciate the range of experts quoted with different views.

Jeff Bezos never wanted this cartoon to become public.

He killed it, and as a result, pulitzer prize editorial cartoonist Ann Telnaes quit.

Make sure everyone sees this cartoon.

If you're putting together new Biological Anthropology courses this year, help yourself to my syllabuses so you don't have to reinvent the wheel. They're textbook-free and link to many assignments lawnchairanthropology.com/teaching/
