Airplanes use radio waves to determine how far off the ground they are. New 5G cellphone services come close to the same frequencies the airplanes use. Here’s how that can be a problem.

Electromagnetic beams of the right power and wavelength can cause pain and zap electronics. Could they also be used to disrupt a person’s nervous system?
Wi-Fi has become a fundamental part of modern digital life, but its foundation is the same as the technology that allowed your great-grandparents to listen to their favorite radio programs.
Is it necessary to control exposure to electromagnetic waves by limiting the number of relay antennas? Yes, but that’s not the only thing.
Did your holiday gift list include radiation-shielding undies to protect your privates from cellphone radio waves? A radiation expert explains they’re unnecessary – your phone won’t affect your fertility.
The design of a new chip to detect the twisted nature of light waves could pave the way for next generation of optical communication technologies.
We find them at the beach, in every sound and light show, the miracle of wi-fi and now in the fabric of space-time itself. But what exactly is a wave?
After the triumph of general relativity, Albert Einstein spent the rest of his life chasing a unified theory, which eluded him right up until the end.
Warfare is changing, and our approach to dealing with our adversaries must change too.
Big data is about processing large amounts of data. It is often associated with multiplicities of data. But the ability to generate data outpaces the ability to store it.
