Nevada is known as being one of the most lenient states when it comes to gambling, fireworks, and getting married; and now it's extending that easygoingness to driverless cars.

As of today, Nevada is the first state to let Google's self-driving cars on the roads. The state's Department of Motor Vehicles issued the tech giant the first license to see just how these cars act and react on busy streets and highways, according to the Las Vegas Sun.

"We're excited to receive the first testing license for self-driving vehicles in Nevada," a Google spokesperson … Read more

We welcome alternative approaches and views from readers, so if you have any suggestions or alternative approaches to these problems, post them in the comments!

Many of us have relied on rapid diagnostic tests at one time or another, whether it's testing for pregnancy, blood glucose levels, or strep throat.

But while dropping fluid samples on a small strip for near-instantaneous results is affordable and convenient, reading results using the human eye means there is the potential for, well, human error.

So researchers at UCLA have taken the human out of the equation as much as possible and developed a digital "universal" reader for all rapid diagnostic tests, or RDTs, that requires no translation of results.

In the journal Lab on a … Read more

BOULOGNE BILLANCOURT, France -- So you think you're a camera expert? Well, when was the last time you evaluated a camera by spending days analyzing hundreds of test photos?

That's what DxO Labs does, over and over, publishing results so far for 185 cameras on its DxOMark Web site. To see what lies behind those performance scores, CNET visited the company as it put one hotly anticipated camera through its paces: Canon's hot new video-capable SLR, the EOS 5D Mark III.

The results might not surprise close watchers of the camera business: Canon's score of 81 … Read more

WHITE SANDS MISSILE RANGE -- I recently watched footage of the detonation of the first atomic bomb at Trinity Site in 1945. A black and white mushroom cloud built up in slow motion. Chills and prickles crawled up my spine.

Visiting Trinity Site One week later, I visit ground zero, where a device called "The Gadget" was strapped into a 100-foot-tall steel tower and set off. Two more nuclear explosions took place over Japan after that successful test, harbingers of the end of World War II.

This all happened a long time before I was born, but I feel a strange sadness as I stand here on a hazy spring day in the middle of the Jornada del Muerto, a desert basin full of scrub and pronghorn antelope. That name translates to "day's journey of the dead." … Read more
