Austrian authorities are investigating whether a university committed a crime when it used corpses as part of research to develop better crash-test dummies, a prosecutor said on Tuesday. Authorities suspect that researchers at the Technical University of Graz might have violated the dignity of the dead by using bodies in tests.

DNA tests soon may solve a century-old mystery — whether a skull held by the International Mozarteum Foundation is part of Wolfgang Amadeus Mozart’s remains. Archaeologists have opened a grave in Salzburg thought to contain the remains of Mozart’s father and other relatives.
