Superconductors conduct electricity perfectly — without any energy losses — which is ideal for many energy-related applications. Unfortunately, even “high-temperature” superconductors only work at extremely cold temperatures, which limits their use. Recently, Cornell researchers showed that even when the superconductors are too hot to superconduct, the electrons in the superconductors form complex...
Hard drives “write” information by using a magnetic field to flip tiny magnets either north pole up or north pole down. Engineers have long dreamed of making much smaller hard drives using electric fields (which are easier to miniaturize) for writing, but...

Solar cells absorb energy from light and create electricity. Today’s silicon solar cells do this very well but are too expensive for many large-scale applications. Tiny crystals of semiconducting ...
Scientists can now grow single-atom-thick films of conductive carbon, or “graphene," by the yard, making this material potentially useful for large-area electronics, such as touch screens or solar cells. Unfortunately, graphene grown in the lab is...
