Nearly a decade ago, a detector searching for ghostly cosmic particles found two anomalous signals in Antarctic ice. But ...

Astronomers studying a distant galaxy cluster stumbled upon ancient radio signals that might hold clues to the formation of ...

For 8 billion years, a burst of radio waves packing more energy than what the sun produces in three decades made its way across the farthest reaches of the cosmos before its light finally reached ...

In a major development, researchers have created a transparent device that can harvest energy from both radio waves and ...

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

Several research projects have previously looked at the potential of converting radio waves into electricity, with mixed success. In 2022, scientists at the University of South Florida said they had ...

The mystery surrounding a strange cosmic object or 'long-period transient' has deepened. This object is bursting with X-rays, and astronomers describe it as unlike anything seen before.

The U.S. military has trialled at least two weapons systems designed to take down drone swarms, but both use microwave energy rather than radio waves. In 2023, ...

Although ocean wave energy is staggeringly powerful—with the waves along the U.S. coasts capable of generating about 63 per cent of its utility-scale electricity in 2023—Hales says its ...

The resulting energy output can be used in a combination of wired and wireless devices. Infrgy says its device transmits an ultra-high frequency RF signal, which is converted into DC electricity.
