All electronic devices emit radio waves when they’re powered on, even if they don’t connect to the internet or Bluetooth. Governments have been using these accidental waves to spy on each other since the 1960s—but this week, a computer scientist at the Black Hat hacker conference took the idea way further than we’d…
Back in 2007, astronomers detected an incredibly brief, incredibly strong radio wave burst in Australia. And now, on the opposite side of the world, astronomers have detected a second blast of similar proportions. Meaning that A) the first one wasn't a fluke, and B) we have absolutely no idea what's causing them.
The 1930s witnessed a technological war between the US and Mexico. Radio channels overlapped with each other, turning the nighttime radio world into bilingual chaos. How did it end? Physics! And diplomacy.
You live your life at 2.4GHz. Your router, your cordless phone, your Bluetooth earpiece, your baby monitor and your garage opener all love and live on this radio frequency, and no others. Why? The answer is in your kitchen.
Are you troubled by strange noises in the middle of the night? Do you experience feelings of dread in your basement or attic? Have you or your family ever seen a spook, spectre or ghost?
There's tech in the works by the folks at Green Peak that could turn your battery-eating remote control into an energy-efficient device worthy of a true "green" environmental label. Couch potatoes rejoice!
