A theoretical particle that travels faster than light, the tachyon has long intrigued physicists and fueled decades of speculation. Initially conceived as a possible solution to quantum and relativity ...

Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

A research group recently discovered the disappearance of nonreciprocal second harmonic generation (SHG) in MnPSe₃ when ...

Europe’s Euclid space telescope has detected a rare halo of bright light around a nearby galaxy. The halo, known as an ...

The Anderson transition is a phase transition that occurs in disordered systems, which entails a shift from a diffusive state ...

Researchers have created a light-manipulating AI chip smaller than a grain of salt that can harness light to power ...

As quantum computers threaten traditional encryption, researchers are developing quantum networks to enable ultra-secure communication. Scientists at Leibniz University Hannover have pioneered a new ...

Reflection: Let us walk this pilgrimage of faith, the Via Lucis, as daughters and sons of the light and as witnesses of the Risen Lord. Let us meditate upon the resurrection of Christ and discover ...

Besides this, the identification of a relevant disturbance of the Treg-IL-2 axis in human SLE as a key feature of systemic autoimmunity and its reversibility could offer the basis for a targeted ...
