NASA at 60: From Space to Earth

The benefits of NASA's space exploration efforts are not limited to the cosmos. NASA technologies provide innovative solutions for people around the world. NASA missions have generated thousands of spinoffs...

Optical fibers have been traditionally produced by making a cylindrical object called a preform — essentially, a scaled-up model of the fiber — and then heating it. Softened...

Computer processors have continued to shrink down to nanometer sizes where there can be billions of transistors on a single chip. This phenomenon is described under Moore's Law, which...

Instead of attaching semiconductors to fabric, an MIT team has found a way to add the technology right into the fiber themselves.
