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?
High-power microwave weapons are useful for disabling electronics. A new report says they ‘plausibly explain’ some ailments suffered by US diplomats and CIA agents in Cuba, China and other countries.
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.
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.
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.
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.
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.
How can you turn lukewarm lager to ice-cold beer in under a minute? A startup has developed a nifty gizmo which does just that, saving both energy and embarrassment at parties. Manufacturer Enviro-Cool…
