A 443 foot container ship grounded within yards of a cabin on the Trondheimsfjord shore, and the shipping company says the same vessel had run aground twice in the previous two years (opens the original)
Read excerpt
Shortly after 5 in the morning at Byneset, on the shore of the Trondheimsfjord, a 443 foot container ship rode up onto land. The homeowner, Johan Helberg, slept through the whole thing. A neighbor rang the doorbell, got no answer, and called him on the phone instead. When Helberg looked out, a vessel longer than a city block was sitting at the edge of his property, close enough to sever a heating pipe. How does a ship end up there in the first place? A container ship inbound for the port of Orka
Lab tests on 50,000 discarded mattresses a day found their foam absorbed three times as much oil, and it chose oil over water nearly seven times more selectively than untreated foam (opens the original)
Read excerpt
A row of foam cubes on a laboratory bench in Arizona, cut from the inside of a mattress. Beside them a shallow dish holding oil floating on water, the way a spill sits on the sea. Drop an untreated cube in and it takes both. Oil, water, whatever touches it first. Four versions of the same foam went into that dish, three of them chemically altered. Polyurethane foam is a scaffold of thin walls around open cells. How much it can hold is a question about that geometry, which is to say about empty s
Three Texas solar farms kept 1,200 megawatts of panels nearly intact through the same hailstorm that wiped out thousands of panels at a neighboring site just miles away (opens the original)
Read excerpt
The hail came through in three separate storms inside twelve hours. One large solar farm in Fort Bend County, Texas lost thousands of panels. Other large projects a few miles away lost almost nothing. What separated them was the angle the glass was sitting at when the ice arrived. A solar tracker is a motorized frame that rotates a panel through the day, following the sun from east to west to squeeze out more electricity. Most large solar farms now use single axis trackers, which tip the panel a
Chinook salmon returned to 88 percent of their historic range on the Klamath River within two migration seasons after four dams came down, with sonar counting more than 21,000 fish (opens the original)
Read excerpt
The concrete was gone, and the river was moving again. Four dams had blocked the Klamath River in California and Oregon for nearly a century. When the last one came down, scientists set up sonar to watch what happened next. Nobody knew how fast the salmon would find the opening. The answer came back in a single autumn. Stationary multibeam imaging sonar sat fixed in the current near the former Iron Gate Dam site, counting fish as they pushed upstream with no netting, no tagging. The equipment lo
After 60 days lying at a 6 degree head down tilt around the clock, volunteers showed reduced deep sleep with no sign the sleeping brain adapted to the posture (opens the original)
Read excerpt
The bed was level enough to lie in, but the head end was fixed six degrees lower than the feet. Healthy volunteers climbed in and stayed there, around the clock, week after week. They could eat, read, wash and exercise without once sitting upright. Researchers wired their scalps overnight and watched what sleep did. What happened to their deep sleep did not follow the usual pattern of adaptation. The six degree angle is not arbitrary. Tilting the head end down drives body fluid toward the chest
