Stunning radio wave imagery captures the hidden beauty of our galaxy

A new view of the Milky Way has revealed how the galactic center would appear to human beings if our eyes were able to detect low-frequency radio waves.

New technology uses lasers to generate radio signals

World's first laser radio transmitter/receiver paves way for ultra-high-speed Wi-Fi

Researchers have, for the first time, used a semiconductor laser to send and receive radio signals. The hybrid electronic-photonic device uses a laser to extract and transmit microwave signals, providing a data rate that may one day lead to ultra-high-speed Wi-Fi.

How radio astronomers will tune into the cosmic dawn from the far side of the Moon

China’s history-making Chang’e-4 spacecraft touched down on the far side of the Moon last week, and it opened up some exciting new avenues of scientific enquiry. Among them is an ability to tune into low-frequency radio waves in ways we never have before, so what could they tell us?

Using wireless signals, RF-Pose could serve as a health care system to monitor patients' movements from the other side of a wall

MIT trains AI to track people's movements through walls

An MIT team has hooked the latest version of a radio scanning technology that can see through walls to an artificial intelligence (AI) neural network. The AI was trained to deduce a person's postures and movements even when completely hidden.

New MIT system wirelessly powers medical implants using radio waves

Traditional batteries are large, contain toxic chemicals, and need to be periodically replaced, meaning they're not ideal for powering medical implants. But new research from MIT and Brigham and Women’s Hospital has demonstrated a new way to power implanted devices using radio waves.

The Square Kilometre Array: How the world's biggest telescope will revolutionize astronomy

The world's largest radio telescope is taking shape. The Square Kilometre Array will be of a scale never seen before, and with the first prototype dish recently unveiled, the search for answers to some of the most fundamental questions about the universe and its origins is set to begin.

Medical

Radio tags made to monitor vital signs

Someday, patients may have small tags placed on their clothing when they enter a hospital or doctor's office waiting room. By the time they actually get tended to, their vital signs will already be known. If so, it'll be thanks to research currently being conducted at Cornell University.

MIT researchers are steadily discovering how to learn more and more about people simply by bouncing radio waves off of them

MIT can now monitor your sleep using radio signals

Have trouble sleeping? MIT researchers believe they have a better solution than attaching sleep-disrupting electrodes to you and making you spend the night in a sleep clinic: beaming you with radio waves in your own home.
