Scientists have developed the world’s strongest resistive magnet, which produced a steady magnetic field of 42 Tesla (T). The system could improve devices that use magnets, as well as enable a range of new experiments that probe electromagnetism.

In a move that echoes a sci-fi series, researchers have developed a material that was able to not only stimulate nerves in rodents, but reconnect them as well. The finding could lead to injectable particles that take the place of larger implants.

Taking a plot point from the 1990 Sean Connery movie thriller The Hunt for Red October, DARPA is working on a super-silent submarine drive that has no moving parts and provides propulsion through the water using magnets and electricity.

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.
