Great Bear Rainforest The Queen of the North was the pride of the BC Ferries fleet—right up until the night she sank. On March 22, 2006, during a routine run from Prince Rupert to Port Hardy, the ferry exited the narrow 45-mile Grenville Channel just past midnight. Then something went wrong. The officer at the helm, distracted by a conversation with another crew member, neglected to turn after leaving the channel, which points like a rifle barrel at the tip of Gil Island. At 12:20 a.m. the ferry's bow met the island's rock at a speed of 17.5 knots, ripping a hole in the hull. One hour and 20 minutes later, the Queen came to rest under 1,400 feet of water. Of the 101 people aboard, 99 survived, thanks largely to the citizens of nearby Hartley Bay, who put to sea in fishing boats in the middle of the rainy, windy night to rescue them. That leaves them skeptical about the pipeline and the tankers it would attract—about 220 a year. Neasloss has hardly known a time when the rain forest wasn't a battleground.

Sound Uncovered Poop Train You may not give a second thought (or backward glance) to what the toilet whisks away after you do your business. But we got wondering -- where would we wind up if we thought of flushing as the start, and not the end, of a journey? In this short, we head out to trace the trail of sludge...from Manhattan, to wherever poop leads us. This all started back when we were working on our Guts show, and author Frederick Kaufman told us about getting sucked in to the mystery of what happens to poop in New York City. Robert and producer Pat Walters decided to take Fred's advice and pay a visit to the North River Wastewater Treatment Plant... which turned out to be just the beginning of a surprisingly far-ranging quest. Want some more sewer fun? Read: As Robert and Pat report, some of that sewer sludge made it out into the ocean. Play: Try out our Poop Quiz:

Five decades of wolf-moose dynamics The wolves and moose of Isle Royale have been studied for more than five decades. This research represents the longest continuous study of any predator-prey system in the world. The most important events in the chronology have been essentially unpredictable. 2. Each symbol on this graph represents the density of moose (read from the horizontal axis) and the density of wolves (read from the vertical axis) for a particular year. Wolf and moose densities are the total number of wolves and moose on Isle Royale, divided by the size of Isle Royale, 544km2. This graph tells a great deal about how wolf and moose populations are interconnected. By contrast, if moose abundance was determined primarily by wolf predation, and if wolf abundance was a good indication of predation pressure, then wolf and moose abundance would be negatively related. This graph shows that wolf and moose abundances are neither positively nor negatively related. 3. 4. 5. 6. 7. 8. 9.
SAT Math Prep A Rain Forest Begins With Rain, Right? Is This A Trick Question? MinuteEarth/Youtube Think of a rain forest — rich with trees, covered by clouds, wet all the time. Then ask yourself, how did this rain forest get started? I ask, because the answer is so going to surprise you. Until I saw the video you're about to see, I just figured that a rain forest starts when a place gets rainier. So I figure that's the order: rain first, forest second. Or so I thought. Now watch this — from science explainer and animator Henry Reich:
