Researchers at Drexel University have created “Faraday fabrics” that can block almost all electromagnetic waves. The key ingredient is a 2D material called MXene, and the development could help protect wearables from interference and people from potentially dangerous radiation.

A research group at the University of Iowa has built what is described as a "remote control" for diabetes management that uses electromagnetic fields (EMFs) to reduce blood sugar levels and improve the body’s response to insulin.

Electromagnetic shielding is usually placed around electronics to prevent interference. Now, engineers have found that a 2D material called titanium carbonitride is excellent at the job, absorbing rather than reflecting electromagnetic waves.

Scientists at EMPA have developed a new aerogel-based material that blocks a wide range of electromagnetic radiation frequencies, forming what they describe as by far the lightest electromagnetic shielding material in the world.

Although it doesn't happen often, it is possible for electromagnetic fields (EMFs) to affect the performance of cardiac implants such as pacemakers. Fortunately, though, a new study indicates that EMFs produced by electric cars pose no such danger.

Soma Laboratory has developed a handheld gadget that taps into the hidden voices of everyday modern objects, such as display screens, park railings and electronic doors. Ether picks up secret electromagnetic whispers and records the audio to a cabled audio recorder.​

A new study from Tel Aviv University suggests that the electromagnetic fields given off by lightning activity around the world could protect living cells from certain kinds of damage, which may have had implications for the evolution of life on Earth.

​While we've seen a number of devices that use ultrasound to ward off mosquitos, many people maintain that such deterrent systems just don't work. The Nopixgo Mosquito Bite Protection Wristband takes a different approach, emitting electromagnetic waves instead.

​Lock up your flywheels, folks, an American inventor is coming after them. RK Transportation is working on an idea that replaces an engine's flywheel with a lightweight rotor with embedded magnets, to apply pulses of electric torque just when they're needed in search of easier acceleration.

​If these walls could talk. A new treatment that smartens up walls might not be about to give your bedroom a voice, but it could give it the ability to track your movements and your use of electronics, thanks to a special electrode-laden coating that turns them into interactive surfaces.

Researchers at Northwestern University have demonstrated that non-invasive electromagnetic stimulation can be specifically targeted to improve precise memories, such as specific shapes and colors of objects.

The question of how to track and locate first responders in an involved structure that blocks radio signals has long frustrated firefighters. Could a NASA electromagnetic tracker help them rescue lives without risking theirs​?
