Today's robots tend to use one of three imaging techniques: cameras, LIDAR, or radar. Cameras see virtually the same views we do, meaning they're susceptible to smoke, fog, light reflections, and ...

Slowly repeating bursts of intense radio waves from space have puzzled astronomers since they were discovered in 2022. In new research, we have for the first time tracked one of these pulsating ...

When the New York Times first wrote about "mysterious radio waves" from the cosmos in 1933, they made sure to note one fundamental caveat: "No Evidence of Interstellar Signaling." Indeed, the radio ...

WASHINGTON — Researchers have developed a new metasurface-based antenna that represents an important step toward making it practical to harvest energy from radio waves, such as the ones used in cell ...

When lightning strikes on Earth, it doesn’t just light up the sky; it sends faint radio whispers into space. NASA has launched a 4U CubeSat under the CANVAS mission to study these very low frequency ...

Researchers report that lab tests of a new metasurface-based antenna that can harvest 100 microwatts of power, enough to power simple devices, from low power radio waves. This represents an important ...
