MISSOULA, Mont.--If you're going to decide how to fight fire, then you'd better know as much as possible about how it works.

That's the idea behind FireLab, a U.S. Forest Service program at the Rocky Mountain Research Station here, where scientists spend their days studying, among other things, the dynamics and behavior of fire, as well as ways to better predictively model how fire might spread.

And while, as scientists, the folks here don't set policy, it is their job to give those whose jobs is to set policy the best data possible. The … Read more

According to Nvidia on Tuesday, the U.S. Patent and Trademark Office has initially rejected an additional eight Rambus claims that Nvidia challenged.

The additional eight claims are based on two patents that Rambus has asserted against Nvidia in litigation. This follows the USPTO's rejection last month of 41 other claims in seven patents that Rambus had asserted, Nvidia said.

Rambus filed patent claims against Nvidia in an International Trade Commission action in November. The ITC litigation involves memory controllers--which handle communications between memory chips and other silicon--related to graphics processors.

"We are pleased that the USPTO decided … Read more

CRATERS OF THE MOON, Idaho--It's hard for me to believe, because I still feel like I just started Road Trip 2009, but I've already driven enough miles to have crossed the entire United States.

Already it's been 18 days, and on Wednesday, I hit exactly 3,000 miles since I started this project. And it was in one of the most foreign and awe-inspiring places I've ever seen: alongside the road adjacent to Craters of the Moon National Monument and Preserve.

I'll post a story and photo gallery on this huge and incredible place tomorrow, … Read more

Can robots be more humane than humans in fighting wars? Robotics engineer Ronald Arkin of the Georgia Institute of Technology believes this is a not-too-distant possibility. He has just finished a three-year contract with the U.S. Army designing software to create ethical robots.

As robots are increasingly being used by the U.S. military, Arkin has devoted his lifework to configuring robots with a built-in "guilt system" that eventually could make them better at avoiding civilian casualties than human soldiers. These military robots would be embedded with internationally prescribed laws of war and rules of engagement, such … Read more

DUGWAY, Utah--"We train warriors and test weapons."

That's how Col. Jeff Snell, the commander of the 388th Range Squadron, which operates the gargantuan Utah Test & Training Range (UTTR), summed up the main mission of his command.

I had spent the day visiting part of UTTR's Maryland-size facilities, and discovered that Snell's words were a very succinct way of explaining what really goes on at the range: Air Force pilots fly in there in screaming-fast aircraft to run bombing training missions, often in advance of deployments to either Iraq or Afghanistan, and, less frequently, … Read more

TERRA, Utah--It seems like Road Trip 2009 has still just started, but the odometer hit 2,000 miles as I was driving through this tiny hamlet.

Terra is near the entrance to the Dugway Proving Grounds, where I was on my way to visit the Air Force's 388th Range Squadron and its Utah Test & Training Center--the largest bombing range in the country,

Since I hit 1,000 miles just a few days ago, I've done quite a few things and, obviously, covered a lot of ground in the Audi Q7 TDI clean diesel SUV I'm road-testing. … Read more

DUGWAY, Utah--In a world where American soldiers in Afghanistan or Iraq might find themselves under attack from chemical or biological weapons, who's looking out for their safety?

The answer lies deep in the western Utah desert, at a U.S. Army facility called the Dugway Proving Ground where, among other things, groups of scientists are researching how to defend against a wide variety of potentially lethal, or at least dangerous, "agents."

"Dugway's primary mission is testing United States and Allied chemical and biological (CB) defense systems and also performing nuclear, biological and chemical (NBC) contamination … Read more

The U.S. Bureau of Land Management, in conjunction with the Department of Energy, this week released six maps that could help determine the location of the next big push in solar energy.

The BLM maps cover areas within the six U.S. states most suitable for solar energy generation and transmission as judged by the U.S. government: Arizona (PDF and below), California (PDF), Colorado (PDF), Nevada (PDF), New Mexico (PDF) and Utah (PDF).

"Only lands with excellent solar resources, suitable slope, proximity to roads and transmission lines or designated corridors, and containing at least 2,000 acres … Read more

COLORADO SPRINGS, Colo.--If there are two things that drive the folks at the world-famous Cheyenne Mountain complex crazy, it's the widely held public perceptions that, for one, the complex has shut down altogether, and that it is synonymous with NORAD, the North American Aerospace Defense Command.

After visiting as part of my Road Trip 2009 project Friday, I'm here to report that both perceptions are quite incorrect.

For one, the Cheyenne Mountain complex is very much still operational. In some ways, in fact, in a world where existential threats come not from the Soviet Union but from … Read more
