# Science Fun: From Egyptian tombs to the litholamination workshop

Welcome to La science s’aMuse, the science program co-produced by UM and Divergence-FM, which takes you on a cruise through the Muse laboratory archipelago. This week, our guest is Séverin Pistre, a researcher at Hydrosciences Montpellier. In the second part of the program, Christophe Nevado shows us around the UM's litholamination workshop.

And for our fourth stop, we're taking you to one of the most fantastical regions in the world: Egypt! More specifically, to the royal necropolis of Tanis in the heart of the Nile Delta. Our guest, Séverin Pistre, is a researcher at Hydrosciences Montpellier. He knows this site very well, particularly the tombs of the pharaohs Osorkon II and Psousennès, whose eternity seems threatened by a few grains of salt. Nearly three thousand years old, these tombs are deteriorating due to the salinization of their walls, resulting in the alteration of the stone and the gradual disappearance of engravings and paintings. And this is happening more than twenty kilometers from the sea.

In partnership with the Louvre and the French Institute of Oriental Antiquities, Séverin Pistre's mission is to investigate this new mystery of the pharaohs by attempting to identify the hydrological and hydrogeological nature of this environment in order to better understand this process of salinization and, why not, attempt to save these incredible testimonies of the past.

In the second part of the program, the report from the Machine Room takes you to Géosciences Montpellier, where Christophe Nevado works as a litholameller. A rare and little-known but essential profession... By preparing rock samples barely 30 microns thick, the litholameller or lithopreparator is an indispensable link in geological research and training. A lively encounter with an enthusiast who has been awarded the CNRS collective crystal.

Science is fun, you've got the ticket, let's go!
