(CAMBRIDGE, Mass.) – When we think about sponges, we tend to think of something soft and squishy. But researchers from Harvard’s Wyss Institute for Biologically Inspired Engineering and John A. Paulson School of Engineering and Applied Sciences (SEAS) are using the glassy skeletons of marine sponges as inspiration for the next generation of stronger and taller buildings, longer bridges, and lighter spacecraft.

In a new paper published in
Nature Materials, the researchers showed that the diagonally-reinforced square lattice-like skeletal structure of ....

In 2016, an inflatable arch wreaked havoc at the Tour de France bicycle race when it deflated and collapsed on a cyclist, throwing him from his bike and delaying the race while officials scrambled to clear the debris from the road. Officials blamed a passing spectator s wayward belt buckle for the arch s collapse, but the real culprit was physics.
Today s inflatable structures, used for everything from field hospitals to sporting complexes, are monostable, meaning they need a constant input of pressure in order to maintain their inflated state. Lose that pressure and the structure returns to its only stable form flat. ....
