Cameras at intersections may curb red light runners, but detractors like to argue that any offset in traffic violations is met with an increase in rear-end accidents. Not so, says a television station that debunked a couple of red light camera myths.

Drivers running red lights caused 762 deaths in 2008, and an estimated 165,000 people are injured annually by red light crashes, according to the National Highway Traffic Safety Administration's Fatality Analysis Reporting System (FARS). To combat these sometimes deadly accidents, many cities install traffic light cameras in key intersections that capture the offenders' license plates, and … Read more

Hedge fund manager Philip Falcone is expected to eventually step aside as the public face of LightSquared in an effort to keep the foundering wireless broadband effort from defaulting on debt, The Wall Street Journal reports.

The move is expected to prompt the company's lenders to approve a debt extension that would keep the company from having to file for bankruptcy protection, people familiar with the matter told the Journal. The holders of LightSquared's $1.6 billion in debt have given Falcone until 10 a.m. Monday to strike a deal for restructuring Harbinger's 96 percent equity … Read more

Sometimes, CNET goes weeks without bestowing an Editors' Choice award. We give the badges only to tech that we love so much, we'd personally buy these devices. There must be some magic in the air (or our drinks) this week, because we doled out not one, but three CNET Editors' Choice awards.

But before I walk you through our award winners (a surprising and diverse group in their own right), I'd like to point out two non-winners that deserve your attention. These two four-star computers, the Origin Genesis and the Origin EON17-S are a desktop and a laptop … Read more

Any barbecue kit worth its salt (or sauce) is going to have a few essentials in it. Topping the list might be a spatula or a food turner of some sort. Additional useful items might include tongs as well as a grill brush to clean the grates before use. And, of course, a light of some kind so as to keep grilling after the sun goes down. Preferably one with magnets.

Not only does the Man Law MAN-F378BBQ Twist Flashlight come with a tripod mount that sticks to the grill magnetically, it also stands by ready for action without the … Read more

With previous product launches, Barnes & Noble has made a habit of underpromising and overdelivering, so it's no surprise that it's shipping its new e-reader, the $139 Nook Simple Touch with GlowLight, a couple of weeks earlier than it previously said it would.

The company says that, "Beginning this week, ahead of schedule, Barnes & Noble will begin shipping units to customers who preordered the device" and that preorders will "ship throughout the month."

We have no way to know what Barnes & Noble's expectations for preorders were, but the company says it'… Read more

LEDs, or "light-emitting diodes," have come a long way since they were introduced as red, green, and blue computer indicator lights.

These days, LEDs are available in endless shapes and sizes, a wide variety of colors and neutrals, and offer many benefits over traditional incandescent lights.

For starters, LEDs can potentially cut energy usage by 25% in the U.S. How? Here's the science, made simple: incandescent bulbs convert most electricity to heat, whereas LED lights convert most of the energy into light. That's why LEDs don't give off heat the way traditional … Read more

Oscar Lhermitte wants to give city dwellers back their stars.

With his project "Urban Stargazing," the London-based product designer and graduate of the Royal College of Art has craftily used LEDs, fiber optics, nylon line, and giant slingshots to beat back light pollution and reconnect people with the aeons-old mysteries of the night sky. His "triangulated structures" stand in for the constellations that have fired human imagination for so long but that are now so often drowned out in metropolitan areas.… Read more

Philips on Sunday will start selling an LED bulb that sets a new bar for performance -- and price.

The company will release the Philips L Prize LED on Earth Day for $50, which includes an "automatic incentive" from the company. The general-lighting bulb came out of the Department of Energy's L Prize competition to develop long-lasting, efficient, and less expensive LED lamps.

Philips claims its L Prize LED is the most efficient 60-watt LED equivalent and improves on features from Philips own existing LEDs.

It gives off 940 lumens, consumes 9.7 watts, and has a … Read more

Sometimes we need to see to believe. I remember understanding on an intellectual level, from a young age, that smoking was bad, but I didn't really get it on a visceral level until I saw a smoker's blackened lungs. The effect was so profound that, to this day, I go so far as to hold my breath when walking past people smoking.

Unfortunately, it's not easy to peer inside our own bodies and check out the health of our lungs. It's also difficult to see the effects sun exposure is having on our skin, especially when … Read more
