Recycled aggregates can match structural concrete strength

A new study challenges one of the most deeply rooted assumptions in civil engineering: that using recycled materials in structural concrete inevitably means sacrificing strength. Researchers from Escuela Superior Politécnica ...

New transistor brings high voltage to microchip scale

Inside every electronic device, the flow of electricity is controlled by a switch called a transistor. For decades, these switches were made from silicon. More recently, engineers have turned to a material called gallium ...

Light-powered soft robots that can keep jumping forever

Researchers from North Carolina State University have created teardrop-shaped soft robots that leap upward or forward when exposed to infrared light—and will keep jumping as long as the light is present. The work demonstrates ...
