Changing shapes at the push of a button

Programmable materials are true shapeshifters. They can change their characteristics in a controlled and reversible way with the push of a button, independently adapting to fit new conditions. They can be used, for example, ...

Collapsed bridge helps inform future flood-resistant designs

Before record rainfall in July of 2018, the Misasa Railroad Bridge spanned a small river some nine miles inland from Japan's western coast. Unprecedented flooding collapsed the bridge, an infrastructure failure that will ...
