Science and AAAS are working tirelessly to provide credible, evidence-based information on the latest scientific research and policy, with extensive free coverage of the pandemic. The porous limestone gained up to one-third of its weight in waterand it's not set to lose it quickly. As for Maurin, he's investigating the builders' marks on the roof support beams.
