# La Science s'aMuse: From Egyptian tombs to the litholamellage workshop
Welcome to La science s'aMuse, the science show co-produced by the UM and Divergence-FMwhich takes you on a cruise through the archipelago of Muse laboratories. This week's guest is Séverin Pistre, researcher at Hydrosciences Montpellier. In the second half of the show, Christophe Nevado takes us on a tour of the UM's litholamellage workshop.
And for our fourth stopover, we're taking you to one of the world's most fantasized regions: Egypt! And more precisely, to the site of the royal necropolis of Tanis in the heart of the Nile delta. Séverin Pistre, our guest, is a researcher at Hydrosciences Montpellier. He knows the site very well indeed, and in particular the dwellings of the pharaohs Osorkon II and Psousennès, whose eternity seems threatened by a few grains of salt. Almost 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 all this 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, to better understand the salinization process and, why not, to try to save these incredible testimonies of the past.

In the second half of the program, a report from the Machine Room takes you to Géosciences Montpellier, where Christophe Nevado works as a litholamelleur. By preparing rock samples as thin as 30 microns, the litholamelleur or lithopreparator is an indispensable link in geological research and training. A noisy encounter with an enthusiast rewarded by the CNRS collective crystal.
La science s'aMuse, you've got the map, let's get on board!
