Dr. Sanziana Roman, an endocrine surgeon at UCSF who was once a voice major at Cornell (and who can sew as well), worked with San Francisco Opera to develop a two-ply mask, made of cotton muslin and polyester corset boning, that allows a full range of facial and jaw motion. The company is already using the masks to rehearse for its outdoor production of The Barber of Seville next month. – San Francisco Chronicle
