Across the United States, college administrators are poring over student essays, recommendation letters and SAT scores as they select a freshman class for the fall.
If this is like most years, administrators at top schools such as Harvard and Stanford will try hard to find talented high school students from poor families in a push to increase the socioeconomic diversity on campus and to counter the growing concern that highly selective colleges cater mainly to students from privileged backgrounds.
The Shell Oil Jackpine open pit mine uses trucks that are 3 stories tall, weigh 1 million pounds and cost $7 million each. There is explosive growth in the oil field areas around Fort McMurray, Alberta, Canada.

Layers of lake sediment are removed at intervals from a core. In a laboratory, contaminants and biological remains are analyzed from select sediment layers to understand lake history and reconstruct environmental changes that often predate periods of direct monitoring.
Canadian researchers have used the mud at the bottom of lakes like a time machine to show that tar sands oil production in Alberta, Canada, is polluting remote regional lakes as far as 50 miles from the operations.
An increasingly large share of U.S. oil comes from Canada's tar sands. There are environmental consequences of this development, but until recently, Canadian regional and federal governments left it to the industry to monitor these effects.

Harry Dent, a financial newsletter writer, has been looking at the Census data, and he's uncovered something odd about American adults. When we turn 50, we dramatically change our clothes-buying habits. It's not gradual; gradual is what we'd expect. Instead, the change is drastic.
You can see it with men's shirts. In our early 50s, American men are at the top of our shirt buying game (either buying more shirts than at any other time in our lives, or maybe we're buying more expensively). Then watch what happens:
The Shell oil drilling rig that ran aground off Alaska last week is now anchored in a quiet harbor so divers can assess the damage. Wildlife officials say they have seen no evidence of a spill from the vessel, which was carrying tanks of diesel fuel. But the accident does raise questions about Shell's plans to drill for oil in the remote and fragile ecosystem of the Arctic.

It's become an annual tradition: bidding up an outrageous price for a Pacific bluefin tuna during the first auction of the new year at Toyko's Tsukiji fish market.
And on Saturday, a bluefin tuna big enough to serve up about 10,000 pieces of sushi fetched a mind-boggling price: $1.76 million. That's about three times as much as last year's tuna and equates to about $3,600 per pound for the 489-pound fish.
NASA is facing a conundrum of large proportions; shuttle-sized, in fact. Now that the shuttle program has ended, NASA is no longer using shuttle facilities and equipment. That includes everything from a launch pad to space in the building where rockets were assembled. So NASA is conducting a secret auction. Orlando Sentinel staff writer Scott Powers explains what NASA is selling, why, and who the buyers might be.
Scientists have cooled potassium gas to one billionth of a degree below absolute zero. But in the quantum world, that's actually hotter than the Sun. It's hotter, even, than infinity degrees Kelvin. Vladan Vuletić, a quantum physicist at MIT, talks about this 'Bizarro World' temperature.
