Engineers Take a Step Toward Using Light Instead of Wires Inside Computers

Using a new algorithm, engineers from Stanford University have developed a prism-like device that can split a beam of light into different colors and bend the light at right angles, a development that could eventually lead to computers that use optics, rather than electricity, to carry data. They describe what they call an “optical link” […]

Microbullets Confirm the Strength of Graphene

A newly published study from Rice University shows that graphene is 10 times better than steel at absorbing the energy of a penetrating projectile. Graphene’s great strength appears to be determined by how well it stretches before it breaks, according to Rice University scientists who tested the material’s properties by peppering it with microbullets. The […]

A Nanolamp with Lightning-Fast Switch

Scientists have developed a light source which converts an electrical voltage pulse into a light pulse by means of a single molecule, possibly serving as a prototype for nano-components that convert electrical into optical signals with gigahertz frequencies. Information is processed and transmitted by ever-smaller components, sometimes with electrons and sometimes with light. Scientists at […]

Artificial Retina Could Help Restore Vision

New research shows that an artificial retina could someday help restore lost vision caused by retinal degeneration. The loss of eyesight, often caused by retinal degeneration, is a life-altering health issue for many people, especially as they age. But a new development toward a prosthetic retina could help counter conditions that result from problems with […]
