'Electronic Fog' From Wireless Devices Might Block Study of Space

As our world becomes increasingly wireless, scientists must grapple with the effects of millions of people using devices like cell phones and laptops. After all, there's only so much space on the electromagnetic spectrum. You might not consider it while Googling or browsing Facebook, but that signal you're transmitting could be making it tougher for some scientists to do their jobs.

That's why the U.S. National Research Center (NRC), in a report released today, is calling for tougher regulations on the emissions of wireless signals. According to LiveScience, man-made signals have created an "electronic fog" that often blocks natural signals from the Earth or outer space. Scientists monitor these signals to keep an eye on temperature and water level changes in the atmosphere, to determine weather patterns, and even to learn about the origins of the universe.

Researchers 'Eavesdropping' on Computers Via Keyboard Emissions



We always knew those electromagnetic emanations would amount to no good, and now here they go ruining any shred of privacy we once thought to possess. Some folks from the Security and Cryptography Lab at Switzerland's EPFL have managed to eavesdrop on the electromagnetic radiation shot off by shoddy wired keyboards with every keystroke. They've found four different ways to listen in, including one previously-published general vulnerability, on eleven keyboard models ranging from 2001 to 2008, with PS/2, USB and laptop keyboards all falling to at least one of the four attacks. The attack works through walls, as far as 65 feet away, and analyzes a wide swath of electromagnetic spectrum to get its results.

With wireless keyboards already feeling the sting of hackers, it's probably fair to say that no one is safe, and that cave bunkers far, far away from civilization are pretty much our only hope now. Videos of the attacks are after the break.

MIT's EMF Bracelet Detects Radiation Poisoning


We've seen our fair share of EMF detectors and other tin foil hat apparel, but no endeavor is complete without the MIT stamp of approval. Cati Vaucelle's EMF sensor bracelet is designed to pick up on any potentially harmful electromagnetic fields, allowing you to dance around the veritable minefield of computers and cell phones in your workplace, unscathed by the -- maybe, maybe not -- lethal effects of radiation being emitted.

Nevermind about looking like a freak -- better safe than sorry, right? The bracelet, sensitive up to 14-inches, features an integrated LED that's illuminated whenever an EMF field over 50kHz is detected. If you'd like to see this prototype in action, check it out here after the break.

Was Wi-Fi Behind the Boeing 777 Crash In London?

Wi-Fi Behind 777 Crash in London?

Last week, a British Airways Boeing 777 on final approach to London Heathrow touched down short of the runway. The landing gear failed on impact and the plane ground to a halt on its belly at the beginning of the runway. Initial findings revealed that the aircraft's throttles failed to respond to a request for an increase in power, which caused the aircraft to come up short. Now, amid growing speculation about the effects of electromagnetic radiation, one woman is suggesting that Wi-Fi interference resulted in the problem.

The 777 relies on electronics for all flight controls, including the throttles. This enables computers on-board the aircraft to handle many of the details of flight, including fully-automated landings at many airports. In this case, when the landing system requested more thrust, the engines didn't comply. The pilots noticed this and manually shoved the throttles forward, but the engines still didn't respond.

Author and pilot Nina Anderson, who wrote 'Worse Than Global Warming -- Wave Technology,' believes that ground-based Wi-Fi signals are the culprit here, interfering with the aircraft's electronics and causing the throttles to fail. Her book, published late last year, ties technology to the prophesied downfall of humanity in 2012, believing that electromagnetic waves will trigger Earth's magnetic poles to shift, causing a global catastrophe. Her latest theory, about the 777 crash, was made public in an Australian Air Cargo magazine, and, like the rest of her book, doesn't seem to have much basis in fact.

The real cause seems to be bad fuel picked up from the craft's last stop in Shanghai. Water in jet fuel sinks and has the potential to be picked up by fuel pumps in the wings when the craft tilts back at landing. Substitute water for fuel and you have a recipe for disaster.

The real kicker, however, is that Boeing 777's have landed at Heathrow hundreds of times with no similar issues, meaning if there is some design flaw in the craft why is it just appearing now?

Are Your Gadgets Making You Sick? (6)

Low Sperm Count

Are Your Gadgets Making You Sick? Low Sperm Count
The condition: Despite repeated reassurances from the FCC to the contrary, those invisible electromagnetic fields (EMFs) emitted by cell phones, Wi-Fi networks and other wireless devices are being blamed for a whole host of health problems, including nausea, upset stomachs, tinnitus, brain fog and short-term memory loss. The most disturbing charge, however, is the link between cell phone use and dwindling sperm counts.

According to a study by the Cleveland Clinic in Cleveland, Ohio, men who gab on their cell phones for more than four hours per day crank out 40 percent fewer baby makers than their non-cell phone–using counterparts. Yikes!

How to prevent or cure it:
The EMF Safety Superstore sells silver-lined underwear, which reportedly blocks harmful EMF radiation. Otherwise, there's always pay phones.
