A new tissuelike material with the squishy stiffness of fat or brain cells can be programmed to undergo delicate shape changes, akin to the unfurling of a flower’s petals.

Built with a custom-made 3-D printer by scientists at the University of Oxford in England, the “droplet network” comprises tens of thousands of tiny water droplets connected by lipid layers. Similar artificial tissues might one day serve as scaffolding for failing tissues or be used to deliver drugs to pl...
