For the first time, researchers have seen how light behaves during a mysterious phenomenon called 'imaginary time'.

Unlike typical infrared night-vision goggles, these contact lenses do not require a power source — and they enable the wearer to perceive different infrared wavelengths that show up in various ...

The satellites the world relies on for navigation, communication and more get their bearings from distant black holes – but ...

LOFAR detects a faint radio 'mini-halo' from 3.8 billion years ago, revealing how galaxy clusters evolved in the early ...

The first ever space telescope, the Orbiting Astronomical Observatory 2 (OAO-2), was launched into the low Earth orbit in ...

It is possible to make a material emit more radiation than it absorbs, violating the laws of physics in a way that could make ...

New research published in Physical Review Letters suggests that superconducting magnets used in dark matter detection ...

“Scientists have long observed that the capability for a material to absorb electromagnetic radiation — a wave of energy in the form of sunlight and X-rays, among others — at a given wavelength and ...

The era of stealth may be ending due to advances in quantum sensing, according to Rob McHenry, the Deputy Director of DARPA. -In a recent webinar, McHenry argued that future quantum sensors, combined ...

This article shows that simultaneous exposure to infinite electromagnetic field (EMF) sources from typical base stations transmitting at multiple frequency bands is lower than international limits.

Revise electromagnetic spectrum for your National 5 physics exam with Bitesize Scotland interactive practice quizzes covering feedback and common errors.

In this paper, a self-sensing model of an electromagnetic vibrator is analyzed to pick up linear velocity directly without any extra sensors. A feedback control system is then established based on the ...
