This is going to be so cool. The US Navy commissioned an electromagnetic launcher for testing on the USS Gerald R. Ford aircraft carrier and the system will be much more efficient and smoother in launching planes in the future. It’s the first time things have been shot off the ship without the old steam catapult system
The air is thick with electromagnetic noise these days. AM radio waves, the electromagnetic hum of computers—it's invisible to us, but birds seem to detect them with their internal magnetic compass. A new study finds that electromagnetic noise disorients European robins, raising the intriguing and frightening…
In an attempt to thwart and discourage the use of cars and other vehicles in suicide bombing attacks, NATO has been funding the development of a compact electromagnetic jammer that can safely cause an engine to cut out before a bomber reaches their target.
In the future we may no longer need knives in the kitchen, at least not food prep knives. That is the idea behind the "Innnovative Laser Device for Cutting of Foodstuff"—entered by a Russian design student into this year's James Dyson Award competition for problem-solving inventions.
To pump out all the radio-frequency signals that let you make phone calls and consume the internet wirelessly, your phone uses small chunks of silicon to create microwaves. Science had pushed the little things as far as they could—but now a nanoscale version promises to make your phone smaller, cheaper and…
You have some sense of what the wires going to and from your computer do. Some bring power; others transmit information from one device to another. But some of these cables look a bit...off.
Putting the right kind of strain on a patch of graphene can make super-strong pseudo-magnetic fields, a new study says. The finding sheds new light on the properties of electromagnetism, not to mention the odd properties of graphene.
Not to be less than the US Navy, the Army has tested their own electromagnetic rail gun, firing several times at Dugway Proving Grounds. Manufacturer General Atomics calls it Blitzer. I call it Hey Enemy Tank, You Have Been Blended.
Tesla's Spirit Radio uses a simple crystal radio circuit connected to a computer sound-in jack to generate spooky sounds from all kinds of electromagnetic sources. As you will see, it creeped the hell out of Tesla himself.
Sometimes it's the unseen that's the most terrifying. In the case of RFID we think there's plenty to dread, but never actually looked at those scary, scary waves. Thankfully someone at the Oslo School of Architecture and Design did.
Scientists have created a table-top-sized black hole that absorbs light. And yet we're still here, and the world hasn't collapsed. Clearly, my high-school science classes did not adequately explain black holes to me.
This is the Cell Phone Disco by Informationlab at NextFest '07, it's basically a large wall covered in LED's. These LED's only turn on when in the presence of the same electromagnetic interference (EMI) that comes from a cellphone. So when you use your cellphone in the presence of the Disco you can "see" the EMI…
This is an electromagnetic photo frame that can make it look like that picture is actually floating. It works because the photo frame has a magnetic field sensor on the top side and a microprocessor and other electronic doodads in the base that ensure the picture is always balanced. This is a great middle-man picture…
