A new type of OLED can generate left- or right-handed circularly polarized light from just one form of light-emitting ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

Everyday life on the internet is insecure. Hackers can break into bank accounts or steal digital identities. Driven by AI, attacks are becoming increasingly sophisticated. Quantum cryptography ...

Nothing can travel faster than light, or 299,792,458 meters per second. But a certain group of particles acts as if it can, a team of physicists recently concluded, potentially paving the way for a ...

Scientists have turned a long-standing sci‑fi idea into working hardware, using pure light to move data wirelessly through ...

The continuous development of bright, stable and highly coherent high-energy light sources is a propellant to the fields of material science, biomedical imaging, ultrafast spectroscopy, and industrial ...

Black holes can’t be formed from pure light. Quantum physics would curb their creation under any foreseeable conditions, a new study suggests. Typically, matter is responsible for black holes. They’re ...
