There a flowstone formation is stained red in places. This colouring is apparently almost 65,000 years old 1 but until now, a part of the scientific community attributed it to a natural coating of iron oxide deposited by flowing water.

High-temperature, low carbon processes: the challenge for the new Canopée laboratory
High-temperature, low carbon processes: the challenge for the new Canopée laboratory
The CNRS, l'Université de Lorraine and Saint-Gobain Group signed, this Friday, October 23, 2020, the creation of the Canopée laboratory, dedicated to the study of materials and "systems" under extreme temperature conditions. The objective is to reduce the carbon footprint of high-temperature manufacturing processes.

Wetting Effect on Torricelli’s Law
Jets at the exit of the tank for similar conditions except wetting; hole radius = 1.75 mm; initial height = 10 cm. From hydrophilic to hydrophobic plate: (a) Glass, (b) Plexiglas, (c) Hydrophobic-glass. Left side: Zoom in of the jets at the hole exit to display the meniscus profiles for the different wetting conditions (i.e.
