Smuggling light through opaque materials

Electrical engineers at Duke University have discovered that changing the physical shape of a class of materials commonly used in electronics and near- and mid-infrared photonics—chalcogenide glasses— can extend their ...

The science of ants' underground cities

Picture an anthill. What do you see? A small mound of sand and crumbly dirt poking up through the lawn? A tiny hole disappearing into the ground? A few ants scrambling around busily. Not very impressive, right?

Self-healing liquid-metal elastomers

Soft electronics are increasingly in demand for diverse applications, but they lack rigid enclosures and are therefore susceptible to premature disposal after electronic applications. It is therefore necessary to create soft ...

A safer way to deploy bacteria as environmental sensors

In recent years, scientists have developed many strains of engineered bacteria that can be used as sensors to detect environmental contaminants such as heavy metals. If deployed in the natural environment, these sensors could ...
