A research team at Chalmers University of Technology, Sweden, has developed new laser technology that could lead to tiny, ...

Researchers in Israel have created a microscopic optical device that could simplify high-power laser ...

A single flat metalens now handles both excitation and fluorescence collection for diamond quantum sensors, enabling ...

When a bone break is too severe to heal on its own, surgeons often rely on grafts or rigid metal implants — but both come ...

A cube of healthy bone is anything but solid. Inside it, countless tiny channels carry fluid and help cells move, feed, and ...

Most space missions rely on chemical rockets for propulsion. Rockets must carry fuel, which increases spacecraft mass and limits their speed and travel distance. For decades, researchers have explored ...

MIT researchers have built a nanoscale photonic device shaped like a tiny ski jump that launches laser light directly off a ...

Researchers at the University of Basel and the ETH in Zurich have succeeded in changing the polarity of a special ferromagnet using a laser beam. In the future, this method could be used to create ...

For decades, researchers have explored light sails as an alternative. These devices use radiation pressure—the force exerted when light reflects from a surface—to generate thrust. When driven by a ...

Inspired by how bones heal naturally, researchers have engineered a laser-structured hydrogel that could one day replace ...

A micrometer-sized liquid crystal droplet doped with fluorescent dye functions as a nanosecond optical switch that controls light output using light alone. The resonant cavity design cuts the energy ...
