Musical manuscript restored with x-rays
Scientists at Stanford University, Calif., x-rayed a damaged musical score to reveal the musical notes hidden beneath a layer of black carbon. The beautifully bound 1797 Luigi Cherubini opera Médée looks like an impeccably preserved relic of opera’s golden age. However, the final pages of the aria “Du trouble affreux qui me dévore” (“The terrible disorder that consumes me”) are blackened with carbon that completely obscures the closing lines.
Shape-memory polymer printed into inchworm robot
Researchers at Harvard and the Massachusetts Institute of Technology, Cambridge, teamed up to produce a 3D-printed inchworm robot made of shape memory polymers. The robot transforms itself from a completely flat, two-dimensional object into a walking inchworm-shaped robot with almost no help from human hands. Shape memory polymers fold along specific hinges; the only human input needed is to attach the battery and motor.
