Researchers have developed pixels that can not only create images, but also analyse them. In the future, this could lead to ...

Russian satellites have been identified as the cause of mysterious, seconds-long bursts of GPS interference across Europe—a rare example of human-made GPS interference coming from space. But ...

For decades, astronomers have been puzzled by strange “zebra stripe” patterns in radio waves from the Crab Pulsar — bright bands separated by complete darkness. Now, new research suggests the answer ...

Since the start of the U.S.-Israel war with Iran on Feb. 28, interference with location-based services has surged across the Persian Gulf. Such electronic interference is often a defensive ...

QWP-based GP-SIDH architecture for artifact-suppressed full-color holography under broadband incoherent illumination: schematic overview (left) and video-rate phase retrieval with high-fidelity ...

In a new leap for neurobiology and bioelectronics, Northwestern University scientists have developed a wireless device that uses light to send information directly to the brain—bypassing the body's ...

A cat’s whisker and laser can show the wave nature of light. When laser light hits a cat’s whisker or a hair, it makes surprising patterns that demonstrate light’s wave nature. The spacing of the ...

Capture colorful light interference patterns on paper. Use nail polish and black paper to make colorful, reflective prints that reveal the wave nature of light. Fill the baking pan with water about an ...

Malicious interference with the United States Global Positioning System (GPS) is a potentially fatal safety hazard that demands immediate attention and unified action. As the Cybersecurity and ...

Knots are generally understood to form due to twists and turns of long, flexible materials that keep shoes on your feet or frustrate your attempts at hanging holiday decorations. A beam of light doesn ...

A simple and beautiful pattern occurs when light is shined through a pair of slightly misaligned periodic structures. This phenomenon is called the moiré effect, which looks pretty and has significant ...
