Researchers cracked the mystery of altermagnets, materials with no net magnetization yet strange light-reflecting powers, by creating a new optical measurement method. Their findings confirmed ...

Light has always been described as an elegant partnership of electric and magnetic fields, yet for nearly two centuries physicists treated the magnetic side as a quiet background player. New ...

In 1845, physicist Michael Faraday provided the first direct evidence that electromagnetism and light are related. Now, it turns out that this connection is even stronger than Faraday imagined. In his ...
