Pulling yourself back together after a breakup can be tough to do. But a new hydrogel has no trouble. Using little more than water, clay and a new, designer compound, scientists have created a moldable gel that is both strong and can heal itself in seconds when split in two. The gel may advance efforts in tissue engineering and environmentally friendly chemistry.

The new hydrogel is more than 50 times stronger than comparable squishy self-healing materials, researchers led by Takuzo Aida o...
