How do we know the speed of light – and why does it have a speed limit at all? Leah Crane explores the history of one of the ...

Researchers from the Department of Molecular Physics at the Fritz Haber Institute have demonstrated the first magneto-optical ...

Researchers built a silver-grooved chip that channels laser energy into nanometer-spaced peaks, beating the diffraction limit and aiding light-matter studies.

When an intense laser pulse hits a stationary electron, it performs a trembling motion at the frequency of the light field.

When an intense laser pulse hits an electron at rest, the latter performs a quiver motion with the frequency of the light ...

An international collaboration of physicists including researchers at Washington University in St. Louis has made ...

While the terms "quantum physics" and "Theory of Relativity" are used casually every day, not many people know what they really mean. Yet these theories have had a profound impact not only on science ...

Space -- the final frontier. These are the words that introduce every episode of classic "Star Trek," the show that essentially popularized the concept of traveling the stars at the speed of light – ...

Can we turn back time? Ask a savvy physicist, and the answer will be “it depends.” Schemes for retrograde time travel abound but usually involve irreconcilable paradoxes and rely on outlandish ...

Many spider species build spiral wheel-shaped webs – orb webs – to capture prey, and some incorporate so-called “stabilimenta” into their web structure. These “extra touches” look like zig-zagging ...
