Imagine a whirlpool spinning in a river, or a tornado swirling through the sky. They don't just spin on the spot: they travel forward while maintaining that spiraling motion inside them. These ...

A new optical device might allow astronomers to view extrasolar planets directly without the annoying glare of the parent star. It would do this by “nulling” out the light of the parent star by ...

Researchers have succeeded in printing uniformly sized droplets with a diameter of approximately 100 µm using a liquid film of fluorescent ink. This ink, with a viscosity roughly 100 times that of ...

Scientists have managed for the first time to create a unidirectional device that significantly increases the quality of a special class of transmitted signals in optical communications: optical ...

Topology originated from the classification of geometric structures in mathematics, and have prevailed in a variety of branches of physics, ranging from the early electronic topological insulator to ...

Scientists at the Max Planck Institute for the Science of Light have managed for the first time to create a unidirectional device that significantly increases the quality of a special class of ...
