In a recent Nature study, scientists have demonstrated an electrically driven perovskite laser using a dual-cavity design, addressing a challenge that has persisted in the field for over a decade. The ...

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 ...

The Nature Index 2026 Research Leaders reveal the leading institutions and countries/territories in the natural sciences, health sciences, applied sciences and social sciences, according to their ...

Nanoscale features of a laser-driven light sail showing germanium pillars and air holes embedded in a poly(methyl methacrylate) matrix, designed to achieve high ...

Laser diodes are convenient light sources, but for precise optical work their often-elliptical beam profile leaves something to be desired. One way to get around this is to couple the beam into a ...

A spacecraft that could reach the nearest star system in about 20 years would need to travel at a meaningful fraction of the speed of light. No existing technology comes close. But a team at Texas A&M ...
