The Trillion-Barrel Tar Pit

Fort McMurray, Alberta, is an unlikely destination for a congressional boondoggle, especially when cold snaps of 40 below make it dangerous to leave any patch of skin uncovered. But here I am in midwinter, 250 miles north of Edmonton, watching a flock of Washington politicians in subzero parkas cling to tour guides like a trail of oversize ducklings. With gas prices approaching $3 a gallon in some states, the US representatives are braving the frigid air not for adventure but to learn about a filthy sort of alchemy, one that turns sludgy, sticky earth into sweet crude oil.

The Armageddon Plan

At least once a year during the 1980s Dick Cheney and Donald Rumsfeld vanished. Cheney was working diligently on Capitol Hill, as a congressman rising through the ranks of the Republican leadership.

It’s like getting a newspaper with no headlines or section pages in which all the stories are strung together end-to-end.

Tired of premium? These cars tank up on vegetable oil

BOSTON ? When Josh Tickell drives his 1971 Datsun 240Z, powered by a straight six-diesel engine, he gets 44 miles to the gallon. He also gets disbelieving stares from everyone else on the road. The bright-red hot rod, with flames shooting out of a dandelion-rimmed globe on the hood, proclaims in fiery yellow letters: “Powered by vegetable oil.”

Pressed for manpower, Army will tap into reserve of former military members

WASHINGTON – The Army is preparing to notify about 5,600 retired and discharged soldiers who are not members of the National Guard or Reserve that they will be involuntarily recalled to active duty for possible service in Iraq or Afghanistan, Army officials said Tuesday.

Scientists explore math behind origami design

SANTA CRUZ, Calif.—On the mantel of a quiet suburban home here stands a curious object resembling a small set of organ pipes nestled into a neat white case. At first glance it does not seem possible that such a complex, curving form could have been folded from a single sheet of paper, and yet it was.
