'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.

Laser Printers Hazardous to Health, Study Finds


According to a study recently conducted at the Queensland University of Technology, laser printers could stand alongside cigarettes and conventional automobiles as a producer of tiny, potentially harmful airborne particles, reports Australia's Courier-Mail. Lidia Morawska, who headed the study at the university's International Laboratory for Air Quality and Health, said yesterday that the bonding of toner to paper was found to produce tiny particles that could be dangerous to human health.

"These particles deposit very deeply in the human respiratory system and can cause irritation which could lead to [cardiovascular] problems," she explained.

While there is still much to be learned about the printers' potential dangers (Morawska admits that there is no way for office workers to identify the level of a machine's particle emissions), she does encourage people to place printers in well-ventilated areas and to sit as far away from them as possible.

New Car Technology Guarantees Green Lights All the Time



Traffic lights exist to control the flow of traffic, ensuring that we don't all go driving like maniacs on the road. But what if there was a technology that made it so we never had to stop at a light -- ever? Believe it or not, that's the idea behind Audi's new Travolution device -- and if early test results are to be believed, the wireless attachment could significantly reduce traffic congestion as well as exhaust emissions.

By connecting wirelessly to "smart" traffic lights, the Travolution calculates the distance of an upcoming light and then tells you how fast you need to go in order to reach the light as soon as it turns green. It's just like driving down your favorite road where you have the timing of the signal changes memorized, only it'll work with every road (well, the ones that have intelligent signals). By having cars constantly moving, traffic inevitably speeds up, gas mileage improves due to less stopping and starting, and less idling means less CO2 production. Can this device do no wrong?

Well, it's clear that the Travolution system has many potential benefits, and as mentioned, a two-year test that Audi conducted saw significant improvements in traffic congestion. But remember that in less than optimum situations (e.g. standstill traffic), the device may not provide any benefit at all. And don't forget that traffic lights will need to be refitted and reprogrammed to be compatible with the Travolution. So while we love the idea of a traffic-free city, we won't hold our breath for an actual release date. [From: Daily Mail]

Electric MINI Cooper Spotted in Munich, Expected at 2008 LA Auto Show


Check it, Cooper fans -- that electric MINI we've been sporadically hearing about is for real, and we've seen the spy shots that prove it. Car has hosted up a slew of non-blurry (gasp!) snaps of the eco-friendly whip cruising around Munich, and just in case the complete absence of an exhaust pipe wasn't evidence enough, maybe the "Hybrid Test Vehicle" decals will make you a believer. Also of note, we're now hearing that the car is on track for a 2008 Los Angeles motor show appearance, which jibes quite well with the purported summer 2009 US launch.
