Researchers at Delft University of Technology have found a new way to cool radio waves all the way down to their quantum ground state. To do so, they used circuits that employ an analog of the ...

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 ...

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 ...

Astronomers from the International Center for Radio Astronomy Research (ICRAR), in collaboration with international teams, have made a startling discovery about a new type of cosmic phenomenon. The ...

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 ...

The circuit was designed to provide an alarm system that would transmit signals across the medium wave or the radio wave. The circuit was designed to provide an alarm system that would transmit ...

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 ...

A team of international astronomers have discovered a new cosmic object emitting both radio waves and x-rays. Astronomers from the International Centre for Radio Astronomy Research (ICRAR), in ...
