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?
Several countries are developing microwave weapons, like this U.S. Air Force system designed to knock down drones by frying their electronics.

For 60 years, physicists thought they knew exactly how coherent a laser could get. Now the ultimate quantum limit to laser coherence has been found, and it’s much much bigger than anybody thought.
Mating laser-driven atomic clocks like the one shown here with microwaves promises more accurate electronic devices.
Researchers have made some of the most accurate clocks imaginable in recent years, but the trick is harnessing those clocks to electronics. Using lasers to tune microwaves bridges the gap.
The short answer is that it depends on the material the cups and plates are made of, and even what shape they are.

It’s been five decades of microwave popcorn and piping hot leftovers in home kitchens. A serendipitous discovery helped engineers harness radar to create this now ubiquitous timesaving appliance.
Some say cancer-causing chemicals can leak into packaging and into your food.
There is no evidence supporting claims that cooking or heating food in the microwave can give you cancer or food poisoning.

Crews patch them, just to see these recurrent potholes come back again. New research focuses on microwaves zapping patches to make a more permanent pothole fix.
Scientists knew the mystery signals were close by the Parkes radio telescope: but what was the source?
Astronomers used to probing the universe always knew that strange signals detected by the Parkes radio telescope were coming from somewhere closer to home. But finding the source was the tricky bit.
Better than your refrigerator.
