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 ...

Wiring up quantum circuits with light

Quantum computers promise to solve challenging tasks in material science and cryptography that will remain out of reach even for the most powerful conventional supercomputers in the future. Yet, this will likely require millions ...

A predatory dinosaur from Brazil and its surprising anatomy

Irritator challengeri was a two-legged, meat-eating dinosaur, or more precisely—a spinosaurid. The knowledge of the species is based on the most complete fossil skull known from this group. With the aid of X-ray computed ...

Apochromatic X-ray focusing

A team of scientists from the Paul Scherrer Institut, the University of Basel and DESY have demonstrated the first-ever realization of apochromatic X-ray focusing using a tailored combination of a refractive lens and a Fresnel ...

Novel crystal compound melts under ultraviolet light

While many materials melt when heated, researchers from Japan recently discovered a novel material in which melting can be induced by ultraviolet light instead of heat. Even more intriguing, this material exhibits changes ...

Face-down: Gravity's effects on cell movement

Researchers at the National Institute for Materials Science (NIMS) and colleagues in Japan have developed a specially coated, light-responsive surface that helps test how the direction of gravity impacts cell movements. The ...
