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 […]
