Bone inspires strong, lightweight material

Tiny synthetic structures are as sturdy as metal

Stacks of wee honeycomb structures that resemble the build of bone can form super strong, lightweight matter unmatched by current construction materials.

Strong but light materials could be useful for everything from armor to insulation but are tricky to design. The strongest known materials, such as steel and diamonds, can withstand thousands of megapascals of pressure but have densities well above 1,000 kilograms per cubic meter.

To design a tough material without the bulk, Jens Bauer and col...
