Briefly noted

The Western Wall of the Old City of Jerusalem has been the object of close scrutiny by scientists of the Hebrew University to examine the effect of erosion on the wall’s limestone. Material with small crystals, studies found, was much more prone to weather induced erosion by which micro-particles are washed out of the stone. Stone with larger crystals kept their integrity longer. The news is to be published in the trade magazine Geology forthwith was already the subject of headlines in the press implying that the ancient stonemasons purposely supplied stone of inferior quality to Herod the Great.
