A team of astronomers led by Matteo Cerruti of Paris Cité University reports multi-wavelength evidence for a repeating, roughly 3-year modulation in the gamma-ray output of the blazar S5 1044+71, a ...

Researchers have created a new photonic chip technology that guides light nearly as efficiently as optical fiber. By bringing fiber-like performance onto a silicon chip, they demonstrate that light ...

By analyzing the data from various space observatories and ground-based telescopes, European astronomers have performed a ...

Astronomers have created the largest and most detailed 3D map yet of a glowing signal from the early universe, revealing hidden galaxies and gas from 9-11 billion years ago. By analyzing faint ...

A unique technique allowed astronomers to see the early universe as a "sea of light" and explore the effects of gravity and dark energy on cosmic evolution.

Emotional intelligence has true value in our work and personal lives. However, first, it's worth asking: Is it possible to determine someone's emotional intelligence by their favorite color? While the ...

University of Iowa researchers have discovered a method to “purify” photons, an advance that could make optical quantum technologies more efficient and more secure. The research theoretically ...
