Actively reducing noise by ionizing air

Did you know that wires can be used to ionize air to make a loudspeaker? Simply put, it's possible to generate sound by creating an electric field in a set of parallel wires, aka a plasma transducer, strong enough to ionize ...

The exciting possibilities of tiny, twisted superconductors

Transporting energy is costly. When a current runs through conductive materials, some of the energy is lost due to resistance as particles within the material interact—just notice the warmth from your phone or laptop. This ...

Light forces electrons to follow the curve

An exotic phenomenon usually associated with high magnetic fields can be achieved without a magnetic field, according to theoretical predictions by researchers from A*STAR and the United States. Their analysis could open ...

Superconductor survives ultra-high magnetic field

Physicists from the universities of Groningen and Nijmegen (the Netherlands) and Hong Kong have discovered that transistors made of ultrathin layers molybdenum disulfide (MoS2) are not only superconducting at low temperatures ...
