SAN FRANCISCO--Researchers have linked global climate change to a tripling in the frequency of large fires in major forests of Alaska and Canada.

Black spruce forests cover about 2.7 million square kilometers in Canada and Alaska--about a third of the area of the lower 48 states of the U.S., and fire records date back to the 1950s. Beginning around 1987, the rate that large wildfires struck the forest jumped from about once every 10 years to once every 3 years, said Eric Kasischke of the University of Maryland at College Park, speaking at the American Geophysical Union conference … Read more

Depleted uranium armor may provide great protection against other tanks, but it's useless against hackers bent on penetrating the networks that tankers and other crews increasingly rely on to move and shoot.

Looking to fill the order for "digital armor," General Dynamics Canada and Secure Computing have teamed up to develop Meshnet, a hardware/software firewall designed to protect networks and digital devices inside tanks and other military vehicles from hostile computer and virus attacks.

Without adequate firewall protection, a tech-savvy enemy could infiltrate the net to eavesdrop, ambush or "blind" a crew by cutting … Read more

Paul Barton, founder and chief designer of PSB Speakers loves his job. He'd have to--over the last the last three decades he's probably logged more hours at the Canadian National Research Council's facilities in Ottawa, Ontario than any other speaker designer. There he dotes on his prototype designs in the acoustically neutral environment of an anechoic chamber, measuring and evaluating every aspect of their performance. Barton typically spends two to three years designing a new line of speakers.

I met with him in NYC a few weeks ago to check out his latest, Synchrony. After discussing the technical highlights of his new babies he handed me a Synchrony One B ($1,999/pair) bookshelf speaker to look over. PSB speakers have always sounded great, but they weren't the most gorgeous looking things. The new ones are altogether sleeker, slimmed down, and really pretty in an understated sort of way. Their heavyweight extruded aluminum front and rear baffles; and curved, seven-layer composite wood side panels display a new, more sophisticated level of fit and finish. The speakers are available in snazzy real cherry wood or black ash veneers.

The sound, especially the top of the line Synchrony One tower speaker ($4,499/pair) was spectacularly vivid. Bass was not only subwoofer deep, it was also taut, so it rendered pitches of bass with rare precision. Listen to Paul McCartney's bass on the Beatles' Sgt Pepper CD and you'll know what I'm talking about. Rock drummers came off particularly well; the sense of hearing sticks beating skins was remarkably clear and clean. Barton's new tweeter was equally astonishing when reproducing the cymbals' brassy shimmer. Livingston Taylor's folk vocals from his Ink CD had just the right combination of body and soul. That's exactly what separates "good enough" mainstream speakers from high-end models; the best ones make you feel like you're in the presence of live musicians. Ah yes, that's the point after all.… Read more

The World Monuments Fund has issued a list of the 100 most endangered sites, and it says islands and ruins are being ruined. The northern-most and southern-most sites are both threatened by the effects of global warming, according to the organization. Many sites suffer from normal disintegration--or war, vandalism or heavy tourism. But changing weather patterns are a serious factor in trying to preserve the Fund's most endangered 100 sites.

Take Herschel Island, off the northern shore of Canada's Yukon Territory. And take it quick, it's going to disappear, experts predict. The island's permafrost is melting, and rising seas are eroding the low-lying land. … Read more

A group of native Canadian tribes are seeking compensation from Manitoba Telecom Services for cell phone signals they claim are violating their air space.

According to the CBC, the Assembly of Manitoba chiefs is trying to negotiate revenue sharing for signals that cross the land, water and air space of their reserves and traditional territories.

"When it comes to using airspace, it's like using our water and simply because there's no precedent doesn't mean that it's not the right thing to do," Chief Ovide Mercredi of the Grand Rapids First Nation told the news … Read more

Biofuel. Hybrid cars. Electric cars. Hydrogen. Those are some of the bright ideas in the future of car tech. Many proponents of the hydrogen fuel cell gathered in Vancouver, Canada, recently to discuss their problems and the promises.

This video from that conference shows hydrogen cars on the road. Models from four manufacturers made a 150-mile round trip during the meeting. DaimlerChrysler predicts that by 2015 there'll be millions of hydrogen cars on the road. The company claims that's not just a lot of hot air.

Forget copyrighted comedy ripped off from some cable channel. Even forget the made-for-YouTube teen fantasy. This is real video of a real-life couple, laid bare before all the world. And the world, as reflected by YouTube, seems to love it.

Canadian TV reports the two otters have become big celebrities thanks to the video. Here you can learn the two … Read more
