...gave Michelangelo all the time he needed to correct his shadows without having to use the washes of black pigment and glue size that the critics believe to be his handiwork. And because his retouching was chemically integrated with the plaster, there is no reason to suppose that the solvent AB-57 would remove...
...left for between one and 24 hours and is strengthened by the disodium salt of EDTA, a substance that aids in the removal of calcium compounds; on the Sistine frescoes it is used in a weak solution, in varying applications lasting at most three minutes. It is an efficient solvent but a bland reagent. The fear that the cleaning has taken off any of Michelangelo's a secco passages seems unfounded.

A three-year-old boy was found...

If the only thing one cares about is keeping Social Security solvent, that could be accomplished by simply raising taxes or cutting benefits, no matter how bad a deal that makes the program for younger workers. But the goal of Social Security reform should not merely be balancing the books. Rather, we should be trying to provide workers with the best possible retirement option, and that involves giving workers more control and ownership of their retirement funds...
