National Geographic magazines and Indiana Jones movies might have you picturing archaeologists excavating near Egyptian pyramids, Stonehenge, and Machu Picchu. And some of us do work at these famous places.
But archaeologists likeus want to learn about how people from the past lived all over the planet.
We rely on left-behind artifacts to help fill out that picture. We need to excavate in places where there’s evidence of human activity – those clues from the past aren’t always as obvious as a giant pyramid, though.
A new machine learning approach offers important insights into catalysis, a fundamental process that makes it possible to reduce the emission of toxic exhaust gases or produce essential materials like fabric.
In a report published in Nature Communications, Hongliang Xin, associate professor of chemical engineering at Virginia Tech, and his team of researchers developed a Bayesian learning model of chemisorption, or Bayeschem for short, aiming to use artificial intelligence to unlock the nature of chemical bonding at catalyst surfaces.
“It all comes down to how catalysts bind with molecules,” said Xin. “The interaction has to be strong enough to break some chemical bonds at reasonably low temperatures, but not too strong that catalysts would be poisoned by reaction intermediates. This rule is known as the Sabatier principle in catalysis.”
Brain Muraresku, author of “The Immortality Key — The Secret History Of The Religion With No Name”, discussing his fascinating journey to discover psychedelic potions from antiquity, reconstruct their history in the development of religion and civilization, and their development into a modern neuro-pharmacopoeia.
On today’s show we are going to be weaving together a really interesting range of themes including psychedelics, pharmacognosy and medicinal botany, history, religion & spirituality, end of life care, dreaming, mental health and a whole lot more.
Brian Muraresku is the author of “The Immortality Key: The Secret History of the Religion with No Name”.
Brian graduated Phi Beta Kappa from Brown University with a degree in Latin, Greek and Sanskrit. As an alumnus of Georgetown Law and a member of the New York Bar, he has been practicing law internationally for fifteen years.
He is also founding executive director of Doctors for Cannabis Regulation. Their work has been featured on CNN and ESPN, as well as The Washington Post and San Francisco Chronicle. In arbitration with the NFL in 2018, Mr. Muraresku represented the first professional athlete in the United States to seek a therapeutic use exemption for cannabis.

Why it matters via Axios’ Miriam Kramer:It’s only the second time pristine asteroid material has been brought back to Earth. Sample return missions like this one are incredibly valuable to scientists.
