Researchers 3-D print metamaterials with novel optical properties

A team of engineers at Tufts University has developed a series of 3-D printed metamaterials with unique microwave or optical properties that go beyond what is possible using conventional optical or electronic materials. The ...

Conch shells spill the secret to their toughness

The shells of marine organisms take a beating from impacts due to storms and tides, rocky shores, and sharp-toothed predators. But as recent research has demonstrated, one type of shell stands out above all the others in ...
